First one of these I have had come in.
Husqvarna 455 IPL http://s30387.gridserver.com/partsDiagrams/Husqvarna%20455%20Rancher.pdf
Issues pouring bar oil out when tipped on the side to fill. Looked and coming from behind metal bar plate.
Not oiling bar. Seen that fix right off. Plastic gear looks stripped and owner painted bar and the paint in mount area has balled up and filled bar oiler hole. Plastic oiler gear is being pita to remove. I think this one has melted and isnt coming off like normal 346 etc ones would being so simple.
Chain brake not working. This one puzzles me. The big spring inside the clutch cover has some how come out of cover and was laying inside. Cant find any hole etc where it made it's exit. Any tricks for getting this spring back in place. I'm having a PITA of a time and just came in to look at IPL and service manuals a little.

I replaced the brake in a 350 cover a couple years ago and it was a lot harder to get the spring in than on a 372.
You have to mount the cover in your big vice with some rags so you don't scratch the paint.
You need to use some device that sticks inside the spring to keep the spring from buckling out. Like a screwdriver that has part of the shank cut off.
It takes both hands and all your strength.
After you get the plastic cover on the spring to keep it from jumping out, you need a way to release the brake so you can get the brake band over the clutch drum.
I removed the brake handle from the chainsaw and used it with the cover stihl in the vice to release the brake.
Then everything went together and all was forgiven and I was, from then on, a new man. I had the service manual and had followed the instructions.
-
I got the spring in after 30-40 mins ;D. I still dont see how it got out. ???
Oil leak is from a hole into oil tank right in front of metal plate.
Oiler gear was melted to the crankshaft. :o Not anymore. ;)
-
Trick for cover and spring. I removed the clutch drum and set inside the cover the way it normally would inside the brake band.
Then installed spring how you mentioned on your 350. Put plastic on. Put cover on saw and drum onto crankshaft, with handle still on saw and engaged brake handle to open brake band. 8) :P
-
So how is this 455 56cc going to compare to my 55 53cc 46mm open port?
-
??? This 455 has oregon chain with 80 on the drive link? What is this chain with 80, never seen that one.
Bar is 1.3mm 050 and guessing 325 didnt really pay attention.
I just found searching a husky labeled chain in 3/8 050 H80. Would this be the chain with 80 on the drive links that I thought was a 325 chain? Guess I better look closer at this chain.
-
With any luck and the local husky dealer has a worm gear in stock. I could be done with this saw tomorrow.
I pulled the oil pump to get to the worm gear better and had to take it off in pieces being it was melted to the crank and really brittle from the heat.
Thanks to Al Smith for the micro finishing stuff I used to clean the crank up with for a smooth finish after removing the most of the plastic bits melted to it.
Hole in oil tank I used some steel putty and putting seal all on top of that.
I havent run it yet. But I really like how these saws are put together compared to the 290-390 series by stihl.

Oh checked the chain and bar closer while I was out there. 3/8 050 72dl b+c.

I totally agree. 029 I did took me twice as long as a 455 I put rings in. 455 is a decent saw IMO mine never fails to start and cut wood. Bought it new in 2002 before I got into saws. I only had 3. Would not buy one new now. Mine still has original chain on it about half used.
Shep

hey cut, why did the gear get melted up? hope the seal isn't damaged...
-
Seal looks good. I cleaned that all up looking.
I have my theory on why. But who knows.
The gear threads were stripped and not turning the pump. The drum where it goes into the worm gear was all stripped out. Just spinning on plastic.
The clutch drum and clutch are a nice shade of midnight blue. The clutch bearing took a licking too. Surprised more didnt happen to it.
Just hope I can get the worm gear tomorrow and find out if the pump is good or not.
-
Does the pump shaft turn freely?
-
Does the pump shaft turn freely?
IMO yes. Seems normal to me.
I'm thinking just lack of knowing and maintenance. Owner ( firewood cutter ) didnt even know it wasnt oiling till I showed him when he brought it in.
-
Figures. They show a worm gear in stock for the 455 between the 2 shops. But they cant locate it. So on order.
-
Part # 537252601 pinion worm gear ordered on Mon and came in Fri. I was able to pick it up today and install. Oiler works great after adjusting to max output and saw is ready to go cut some wood.
Funny part was they ordered 2 so they would have a extra on hand. I was like cool I'll take that one too and put it on my shelf. ;D
-
Have you cut with it? I was just wondering how they run.
-
It's Running 20" 3/8 oregon vanguard like the new poulan 2050 comes with. My softwood piece today might have been only 8" and the walnut piece maybe 11" and it cut good in that. Not a real test. Need little bigger to tell anything.
Fast forward to evening.
Just went out to the secret wood pile stash with 660mag and got a truck load of wood to test in, hard maple mostly. Will have to see before it is picked up tomorrow afternoon.

It's Running 20" 3/8 oregon vanguard like the new poulan 2050 comes with.
I just cut a 16" piece and 20" piece of hard maple with above chain set up. Saw felt smooth and cut as expected for it's cc size. I like this saw for a clamshell design way better then the 290 series by stihl.
I then cut with the 55 I took in trade ;) with a afm 46mm open port topend. I was only running 15" .325 and stihl rsc chain on it. If they were running same bar and chain they would be close. I dont have time to switch them back and forth right now.
I then ran my 60cc poulan that has a hurt piston in it but still pulling 130psi with new ring and 455 had more toque in the cut then the old 3750 that and the poulan 365. I guess I should pull out one of the new PP 330 I have.
The 455 was way smoother in the cut then all of the above saws I ran. It just needs a better chain then the vanguard IMO.
-
Sounds like the 455 is a good saw.
-
Just digging up some specs.
Model C.I. C.C. H.P. LBS. Idle Speed Max RPM
455 3.4 55.5 3.4 13.0 2,700 13,500
55 3.2 53 3.4 11.4 2,500 12,500

There are a lot of 455's out there in home owner land.
-
My buddy dropped his 455 off because its not oiling .I tore it down and everything looked ok. Worm gear looked fine also. I robed a oil pump out of a 350 and still no oil. Has anyone ever had to prime a oil pump before? I don't see a filter in the tank either. I drained the oil and put some gas mix in the oil tank. Mix came out. I emptied the tank and put bar oil back in and nothing. Any suggestions??
-
Ron there should be a filter type strainer on the end in oil tank if you look at IPL in 1st post here.
Ideas to try. Since the 350 oil pump you know is good with your 350 worm gear and 350 oil pump didnt work with 455 worm gear. Put your 455 oil pump in 350 with 350 worm gear that works. This should tell you if 455 oil pump or 455 worm gear not working properly.
-
Thanks kevin. I'll try that
-
Update. It was pluged between the oil pump and the oil tank. I took the pump off and sprayed carb cleaner in the oil line. Pumps oil fine now.

Hope you put a strainer on it if it was missing inside tank.

hey guys, I have a few 455 ranchers and found out the hard way that the older models didn't use a fine enough screen to prevent the feed line from clogging. the newer models on the shelf now use a different hose and a finer screen, they are interchangeable. the newer style screen is white plastic so it's easy to tell that's it's the new updated one.
-
Got a 455 coming into today. Seems like alot of oiler issues on these, are you seeing this too?

Thank you so much for this info. Thats what was wrong with the 455 that came in today. 8) 8) 8)

There are times that a non invasive solution is needed like a oil tank of kerosene to flush things out?
But the real solution to the problem has been already posted by others.
I just mention this as removing the pump and replacing the pickup tube is beyond the scope of Joe firewood.
-
I removed everything, gear, oil pump, both lines cleaned everything. Flushed the oil tank out. Reinstalled everything and it worked again. The line inside the tank was plugged up going to the oil pump. Fines were actually at the pump entrance hole too.
So ordering the updated stuff is on hold as owner needs saw back now.
-
Husky 455 came in. Needed another drive link removed.
Was a new stihl RS chain sold to him last year by me.
Also had removed a link from a chain he had last year. Told him your either not getting oil to your chain and creating heat or your running your chain to long dull. Does that sound right to you guys? Thats my WAG of what he has going on. His chains stretch so bad, a 72DL 3/8 to have to take them to 71DL.

3/8 spur clutch drum 537291604
Needed a new decomp etc too 503715301

Not cut through, but close. Also aftermarket decomp just almost cost him a saw topend.
-
Locals 455 gets road hard and put up wet. Literally.
Imo not going to be worth it this time scoring started 100psi.
Not getting fixed. Owner going to run it till cant cut anymore. It's past the wont idle anymore stage. But will take throttle and still make cuts.
