Title: 55 rancher help
Post by: mrbb on November 17, 2012, 10:51:57 pm
Ok I am new to the site, and looking for help
 I have a older 55 bought about 2002
 it has been to several husky repair centers since I have it, just never seems to run right or for any length of time
, think it has been in shops longer than I have it!
 BUT  I am currently having a problem of a  gas leak, its leaking  out of the cap!
 I replaced the o ring, then the cap, then a second cap, to no help!
it seems to be under pressure and actually bubbles out even if on its side, when on over a half a tank, and if left standing normally will almost drain empty over night!
 I had it in a husky repair center last yr for same problem,  and they fixed it, after having the saw for 3 months, seems all the dealers here move like snails, one had it for 6 months once for it not idling! and gave it back to me telling me they didn't know waht was wrong with it, second dealer fixed it under warranty in 2 months! almost alike a lemmon of a saw! goes from running great to lousy at will!
but  about 6 months later it started leaking gas again, rather than go back to shop,
 I just kept it low on fuel and kinda gave up on solving the issue!
 But with all the storm damage from Sandy
 its been getting a work out, and leaking gas like crazy every time I am done for the day, next day it is out of gas, wasting me a lot of fuel and pre mix!

 so what can be causing this thing to leak gas?? or how do I fix it , I know there is no cracks in the case, and the cap and O ring are  new, I now have 4 gas caps, and all are pretty much new


when I open the cap I seem to get a release of pressure too, and it again leaks out the cap only , I have even tried bigger O rings and even two O rings to no help??
 please help

Ok I might be just not seeing it, but I don't see any  parts being numbered 1-15-  or what ever on that link
am I just missing it?? I did go to the fuel link(on left side) but again didn't a list of parts there  numbered 1 to??

 what/ how , do I change/check the vent??
  sorry to seem like a dummy here , but I never really worked on a chain saw before, so all the help you could offer would be much appreciated

OK Now I am looking at the link closer, But on this 455 , it shows a primmer bulble, and mine doesn't even have one??
 and again not to sound like a dummy, but NO where on that link is a price list all it is , when I open it up is a 15 page PFD service manual for a 455 rancher, so am I missing something ??

OK I am looking on that site for the 55, and looking at the vent, how does that get removed?? does it screw in or is it pressed in, and if pressed in how do you get it out??
again I never worked on one before so, ??


here is the link

LOL that explains why.   I was showing IPL's for the 455 you ask about originally. Least you figured it out that you had a 55.  8)
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 11:12:04 am
OK the vent is just pushed in, how do you get it out to replace it
 and Yes the dealer I was talking to kept telling me how the 455 replaced the 55, so guess I had that in my head when I started this,
 
 but thanks for the help so far much appreciated

 and last can the vent be removed without dis assembling the tank??, like as is, and just either pull or push it out some how??
 thanks again
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 01:04:37 pm
There are two parts to the vent.

First, there is the black tube that extends to the opposite side of the gas tank to prevent spills.

Then second, there is a little filter disk that fits in the outlet of the vent. This disk is easy to get out with a scribe or ice pick.

There should not be any reason to need to remove the tube? They are hard to get out because there is almost no way to get a hold on it.

Some later model chainsaws did not have the filter disk but had a plastic elbow with a tubing nipple on its end. The tubing went up inside the carb air box area into a loop and then connected to a nipple in the bottom of the carb air box that exited to the outside.
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 01:07:48 pm
OK so to remove I have to pick out the disk then first and then I am guessing push the tube out then??

 and if mine is an older one(made in 2002 I believe ) then it would be in the air box instead??
thanks again for the help

Husqvarna 51 55  IPL   http://s30387.gridserver.com/partsDiagrams/Husqvarna%2051%20and%2055.pdf

Looks like it is on the rear right side of tank area.
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 01:19:24 pm
The ones with the tube that goes up into the carb area would be 455's recently made.

All the 55's had the little air filter disk. This may be felt, foam, or some type of porous plastic?

When you pluck the little filter disk out, you can see the part of the black tube where the little filter fits but there is nothing to grab onto to get it out of there?

Normally you cannot get to any of this for it is in the top right hand side of the gas tank between the gas tank and the rest of the chainsaw.
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 01:19:51 pm
yea thats why I was wondering if you have to remove the tank to get at it or not?

 and whats the best way to change it then??
Title: Re: 55 rancher help
Post by: Magnus on November 18, 2012, 01:30:15 pm
Loosen rear av mounts, out with tank lid, Angled pliers to grab the plastic tube with and push it out. Filter too...

I doubt that is the case tough. I think it is a carb/fuel issue.

You should have pressure in tank. It is natural and correct. Pinch the fuel line and as you take it of inlet and release it should squirt 30cm or more out on bench when there is pressure.
To get pressure you wiggle it from side to side a few times, 5-8...
I do that on start up of all Elux saws, saves a bunch of pulls.
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 01:35:24 pm
OK magnus
 the saws runs pretty good right now, maybe a tad high on idle, but its winter here now, so colder air always sems to do that here on a summer setting once wamed up

 but this saw did this before, leaking from tank when put down for the day or even a few minutes
 and last time I believe the dealer changed this filter and it solved the problem, thus why I am leaning to it being the issue

 I don't see how the carb would cause enough pressure for gas to be pushing out on the cap/ past o ring
 the filter being blocked or faulty doesn't really either to be honest  but can see how it not breathing can build up extra pressure I guess

 so what carb issue do you think would cause the gas to blow out then??
Title: Re: 55 rancher help
Post by: Magnus on November 18, 2012, 03:01:01 pm
If it runs OK now, it is not hardware that is at fault.
It is likely a fuel thing I suspect.



Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 04:43:38 pm
well like I said it runs OK, idle could be a tad better but runs good enough
 BUT the gas leaks out rather fast out of the cap, it bubbles out, can even hear air coming out, like its under pressue to the point of blowing passed the O ring
 and I have tried new caps/o rings, still leaks
 so I am guessing that the vent if not working causes [pressure to build enough to do this??
 or? I guess it could be something else, thus why I posted here looking for help
  it does Idle high after a cut throught say a telephone sized tree for a few seconds then comes back down, whne idling High it keeps teh chain rolling, but once it comes down its fine
 again I believe that could also be caused by the colder air now, and the fact the tank isn't breathing and changing fuel air intake NO??
Title: Re: 55 rancher help
Post by: man of stihl on November 18, 2012, 06:53:10 pm
Did it run ok when you unscrew the cap and released pressure from the tank or did it run the same?
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 07:31:42 pm
well to be honest I didn't try running it with the cap off or even open some, as again it ran more or less OK when cutting no boggs or issue;'s just when you let off the throttle after a cut it would rev a little longer but then come down in a short time period, so not a issue  really, just had to pay attention as the chain still spun till idle dropped down
 my bigger worry/complaint is the gas leak, as if i put it down on a full tank in a short period of time it makes a puddle under it, and just smells up anyplace I store it if there is fuel in it!
 plus a hot motor and leaking gas to me seems like a bad combo
 so need to fix the gas leaking first and then will see about the idle
 it idled fine in warmer temps, so could be temp related
 so suggestions on best way to remove the breather beside above is still appreciated
 will try to get time on Tuesday to fiddle with it, and order a new breather on Monday from local shop,
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 07:35:30 pm
Sounds to me like t\you have two problems

ONE:  Your idle fuel mixture is too lean.

TWO:  Your fuel cap is leaking.
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 07:38:52 pm
well the air fuel might be off now in the colder air, and NO its not the fuel cap, have tied 2 new one's and new O rings
 its building pressure in the gas tank and even with the saw on its side it will bubble gas out the closed cap, and even make a air release sound when you open the cap
 I also believe the pressure in the tank is causing possibly some idle issues too maybe, just maybe
 but before I play with carb, I need to fix gas leak
 I know the tank is not **** or damaged and again its not the cap
 this is the second time this saw has had this problem, and last time, the breather was replaced and it solved the leaking so??
but last time a shop did it took the 3 months, and now I want to just try and looking for tips I guess

thanks will look at that and see what I find then
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 07:52:47 pm
Gasoline has a vapor pressure that varies according to it's temperature but is often in the range of 4-7 PSI.

Most tank vents have a duck bill rubber check valve inside them that lets air IN but will not let any air OUT
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 07:55:45 pm
OK well, ?? that confuses me some, as like I said before I had same issue, and the shop SAID, have to take that word as I wasn't there, and the problem went away
 they first tried a new cap, making it a third one as I bought two thinking that was the problem at first
 But any ways
 after they replaced the breather , it stopped leaking so??
 that again is why I am leaving that it is the source of the gas leak again
 but again open to other idea's
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 09:00:39 pm
There was a newer cap design that Husqvarna started using around 2005. Instead of having a O-ring seal, there is a molded rubber band with ribs. They have superior sealing capability compared with the old style caps.

The old style caps with the O-ring have 3 straight sided tabs sticking up on the cap. These tabs are thin. There is a wider middle one with narrow ones on each end.

The newer style cap, the tab is smooth, thick, and more rounded. There is a screw driver slot in line the center of the tab. But more important the sealing gasket has a broad flat sealing surface with tiny ribs to aide the seal as can be seen in the picture.

Either cap will fit either style tank on the chainsaws that I have. Talk with your dealer.

Below is a picture of the new style cap.

(http://img.photobucket.com/albums/v11/jamesirl/21Vr9jCn3ML.jpg)

I have changed most of my old style Husqvarna gas and oil tank caps that didn't seal well with the new style caps from the dealer.

I have a chainsaw currently that the old style cap leaks unless I tighten it just a little tighter with a wrench than what I can with my fingers. I will replace it before warmer weather returns.

The next time you remove the gas cap, inspect the area of the tank where the cap fits for cracks, just to be on the safe side.

Post by: mrbb on November 18, 2012, 09:51:43 pm
thanks for the info on caps
 the caps I have, I have 4 all together all are the same with the last one's I bought being last yr
 and I am sure the tank has no cracks, been keeping close eye on it
I wish my local dealer were not so terrible to deal with, but will stop by to order a new vent and ask about the new cap style, and try one , but again, no matter how tight I tighten mine now, it still leaks, and don't want to force tightening and maybe crack something too'
Title: Re: 55 rancher help
Post by: 660magnum on November 18, 2012, 10:06:20 pm
I agree that you may crack the tank if you are not careful.

I actually get most of my Husqvarna parts over the Internet.

If you need help with part numbers or sources, just ask?
Title: Re: 55 rancher help
Post by: mrbb on November 18, 2012, 10:09:32 pm
thanks, but I prefer to buy locally when I can , and after looking online I seen about 5 different style caps that all say there for the  55 saw
 so this way I can take one with me I have and try to get a different style to see if a new stye will work or not
 but I still think its not the whole issue, the cap that is

Post by: farmboy on November 19, 2012, 07:43:38 am
I push the vent out with a pair of long 45* needlenose pliers.  Then take air hose and blow the little white vent out.  Replace the little white vent tap back in with round punch or a nut driver slightly smaller than black tube.
The new style cap is the "Dog" for stopping the 55,261 and more from leaking.  I've replaced the oring and still leak use new old style cap and still leak after 1-2 removals.  Again get the new style it works.

thanks farmboy, appreciate the imput  I will get a new cap and try to remove and just put in a new vent, and hope that solves the leaking
thanks again all
Title: Re: 55 rancher help
Post by: mrbb on November 22, 2012, 06:14:15 pm
just an update
 I made it the local shop, called first and they said they had a gas cap and vent in stock
 got there only to find out they had neither one
 so they ordered it
I decided to give it a good cleaning and have a close up look at it
 well this is the first time I have taken the air filter off sice it was in the shop for idel issue and the gas vent deal last summer
 once I removed the air filter I found that there was only one screw holding the carb on, guess last shop forgot to replace both??
 so I am now leaning that maybe that is why it idles is a little off, sucking in some air maybe, so need to order a new screw for that too, I also found 2 other screws missing
 so that's the last time that shop gets any business

 But on the fuel breather vent
 I don't know, I cannot see it in the tank,( I dumed out all the fuel first)
 or can see where the heck it is at or how to get it out if I find it?

I looked at the service  manual pic's/ drawings of it and well I do not see one on my saw where it is on the drawings??
 so now I am confused to say the least

I added just a couple ounce's of fuel after cleaning it up and putting back screws on all but the one carb screw(didn't have one)
 and it fired right up idled just fine
 BUt as soon as I shut it off/put it down
 it started leaking fuel out the cao again
 its like its under pressure, so again I am still thinking its the vent, but not sure how to replce or even find it now???

Post by: man of stihl on November 22, 2012, 07:18:00 pm
Looking at the clutch side of the saw. If you were to separate the handle\fuel tank from the crankcase you would see it better.Empty the fuel tank and Look in the top of the fuel tank. You will see a needle like part of the vent sticking inside the tank. On the outside it will be a recessed screw sized hole. Hope that helps. I dont have a 55 or i would take a pic for you.

Post by: mrbb on November 22, 2012, 08:09:18 pm
Ok will look again tomorrow, I was just looking in the tank and with the top cover off
 so I have to split the case/remove the carry handle  to change/replace it??
Title: Re: 55 rancher help
Post by: man of stihl on November 22, 2012, 08:33:07 pm
No you shouldn't have to. I was just trying to describe where the vent is located.
Title: Re: 55 rancher help
Post by: mrbb on November 22, 2012, 08:36:14 pm
OK thanks
 and  I was hoping I didn't
I will look again tomorrow and see if i can find it
its at the top of the tank, I gather, I
 know I can see the two screws molded inlets for the carry handle, is it near them?? would you know?? maybe above them or?
Title: Re: 55 rancher help
Post by: man of stihl on November 22, 2012, 08:47:37 pm
Yes. top of the tank and close to the handle screws but higher and back a little further.
