the complete saw has a good gouge out of the front of the piston but i have 2 other topends that are basicly like new to use, plus an alomst complete other engine/saw. no bother ;) i have a complete titan 57 inventory at my disposal if i ever need parts
not to shabby for a 50 note. imo.

Say what's that blue and orange button looking thing ? I certainly don't have any like that on the Titan 70 which is only one of that series I own .

Well depends on the saw model I suppose .The impulse operated  oil pumps on the 10 series and large reed valves were about the best ever built .The ones on the mini macs were about the worst .Then too compairing a mini Mac to an SP 125 would be like compairing a Yugo to a Cadillac .

I've never seen much less worked on a Titan 57 .I would have thought it was patterened after or like the Titan 70 but that evidently isn't the entire story . .Actually what I know about Italian made Macs is about thimble full if all knowledge of same would fill the Atlantic ocean ,I'm just dumb about them .

oh don't get me wrong about the oilers in them there macs ;D they have worked flawlesly for years. only after a million cords of wood did they start to show a few problems. the one main sticking point of them though is the fact they had to be re-installed absolutly positivley exactly 100% correct to work properly if you had them out. whereas any gear driven pump will work so long as the teeth don't get chewed or plugged up. the pulse style pumps are quite a bit more finiky to work with. especially with the age thing coming into play. :) even nos parts are hit and miss to be working without a little quality time getting the check valves moving and seating. they did prime better than the gear pumpers.
the titan 70 was a good saw for it's size. but thats about it, only good. there were better saws out in that size that would out do it stock for stock.
the 57 was a real runner back in the '90's in the 55-60cc class. when you could keep them running. their only downfall (and reliability issue) was the fuel/impulse and oil lines would fall apart after a month and they would burn them selves up, and quickly. if you were lucky enough to save it before that, and changed out the lines, it would last as long as any other saw out. and out run some of the bigger ones.
i remember when we got the first batch of jonny 670 champs in. awsome saw! really strong and fast. the titan 57 would cut right beside them no problemo, until you put something bigger than the 20" (same chain, same wood). then the 670 would be all over the mcculloch like a fat kid on a twinky.
even by todays standards, the titan 57 is still competative for weight and power.
on a side note: the titan 50 was a turd.

t'was totaly stripped down except for splitting the case, new crank seals, fuel/impulse/oil lines, new carb (yes, new carb ;)i had one),plug, and bar. i didn't have a correct chain (getting one on tuesday) but the cm chain that's now on it works pretty good for semi chisel.
she runs gooood! very good. just like a new saw. forgot how much i liked these. this one just might be a keeper.
VROOOM! VROOOOOM! VROOOOOOM! ;D

Good looking job .

On that 70 I may have over estimated it .Cutting some hard oak yesterday at the GTG it didn't do quite as well as I thought it would . I had thought for a while it was about heads up to a Stihl 044 but I was mistaken although for 70 cc's not too bad .Fact is it played second fiddle to both a 6-10 and a 700 both being 70 cc saws .

Ha on that I imagine Kevins ears are still ringing from the 6-10 which has an early style gutted muffler from a 10-10 .The one that has the sweep in the bottom rather than a square floor .Not much restriction on that one ,loud . ;D
Title: Re: titan 57 the saw the legend

hey al, the t70's were a good saw, not as much torque in the cut as an 044 and a little more "peaky" but they were a good srong runnger. and could be made to run better quite easily. i found they like to be a little fat, tuned around 11500 to just under 12000rpm. most would sound a little lean at anything over 12000rpm anyway :)
 i have no idea why mcculloch couldn't make a quieter muffler for those 10 series saws. my gawd, you'd think the person who designed it was already deaf from birth :D probably not even born with ears ;D but man do they ever make great torque.
on a side note. about 10 years ago i had an older gentleman show up with a really beaten to hell pm700 he wanted the chain sharpened on. he dropped it off and said he would be back in a couple few days to get'er (his words). i sharpened the chain, made another for it and decked the bar.
i go out to test it in the big log out back and the thing was winding up waaaay to high. put the tac on it and she was right around 15000rpm, but still burbling. i tried to get that saw to run properly at 12500 but she was having none of it. it just wouldn't pull it self throught the wood. no air leaks or problems i could find. i spun it back up to where it was and set it on the shelf. guy comes in 2 days later, i asked him about it and he said that was where it was when he bought it new in '79 and it has never wanted to run anywhere else. man did that saw cut it's as$ off! it would hold really good rpm's in the wood. that saw is still going today after cutting an honest 15-20 full cord of wood every year up until about 5 years ago when the old guy left this earth. his grand son lives a few properties down from me and still uses it for a tractor bucket saw. still pulls 160psi comp. and looks good through the exhaust and intake. some very minor scorring on the intake side but i wouldn't pull it down for that.
Title: Re: titan 57 the saw the legend
Post by: Al Smith on October 09, 2011, 02:29:09 pm
It's typical for a 10 series to scuff the intake side ,doesn't seem to hurt them though .The air filters weren't the best .

I never tached a 700 but I have that 6-10 and WOT is over 15 thou .Similar but not the same .The 700 has porting and transfer much akin to the 850 whereas the 6-10 is more like the older 10-10's with a full skirt and three semi closed tunnels ,grooves what ever they might be called .

Probabley because of the torque both the 700 and especially the 6-10 could handle an 8 pin but it really doesn't make any diff to me anymore .They're pullers and that's what I like .

On the 70 perhaps a little better tuning is in order but then again I seldom use that saw simpley because of it's rarity .That aside the saw has a good balance and to me at least is a comfortable saw to operate .

man, ran the 57 last night for a couple of hours at a friends house. this saw runs nice 8) i'm running a 16" bar/chain, but
an 18" bar is about perfect on it. no idea who decided these should come with a 24" :D
Title: Re: titan 57 the saw the legend
Post by: Al Smith on October 12, 2011, 01:08:29 pm
 I can't say as I've ever seen a Mac bar in 18" for what would be the same size as the 10 series bar mount .16" 20" 24" 28" and 32" .The old large mount bars for like the 250 ,125 etc came in 18" .
Title: Re: titan 57 the saw the legend
Post by: brokenbudget on October 12, 2011, 03:26:10 pm
up here we sold the pm700 with a 18" bar/chain, most of the time. we had them in either oregon, windsor or the mcculloch brand. :)
of the handfull of the 850's and double eagle 80's we sold, they went out the door mostly with 18" bar/chains. some with 16" on them. nobody wants long bars 'round here, we just cut fire wood :D a big tree thats good for fire wood around here is around 2'dia. nobody wants to touch any bigger.
the titan 57's that we sold were offered with 16"-24" (we recomended 18"-20" tops). some people wanted the 24" bar...... ::) ;D
Title: Re: titan 57 the saw the legend
Post by: Al Smith on October 12, 2011, 03:42:20 pm
Just seems odd to me . Usually on an 80 cc a 24" is about the right size . A 60 cc either 16 or 20" .Then again they do things slightly different depending on the location I suppose .
Title: Re: titan 57 the saw the legend
Post by: brokenbudget on October 12, 2011, 04:39:29 pm
we had one older fella, about the time i started at bentons, ask for a 14" bar for his 850 ::) he was going to use it for cutting ends off of the posts he was splitting. john told him he would have a loose crank in about 5 tanks if the saw was set properly.  theres no way you can load an 850 with a 14"bar/chain combo in cedar. nobody made a 14" bar for the 850 anyway. the guy was rather dissapointed. he ended up with a 16" ;D and we never seen him again :D good. guy was a miserable prik, to say the least.

Speaking of which ,I used the 805 today to drop a 36" ash . I just had to do it rather than let it be a shelf queen all the time .That thing handles a 24" like it's childs play .
Title: Re: titan 57 the saw the legend
Post by: brokenbudget on October 13, 2011, 09:44:12 am
yep! a 24"er on an 80cc saw is fine :) throw one on a 57cc saw and it turns that poor saw into a tired dog. :D
Title: Re: titan 57 the saw the legend
Post by: Al Smith on October 13, 2011, 07:08:08 pm
I did have a 24" on a 60 cc once buried .It pulled it okay .The saw was ported though, 038Av  By the same token I ran a 32"  on a 72 cc ,also ported .

That aside I agree a 16- 18-20 is a better option for 60 cc stock .

titan 57 is still my firewood saw today and is the best saw ive ever owned, keep good lines in it and its one of the best all around saws ever produced. Run a castor based two cycle oil like klotz supertechniplate and its very likely you wont live longer than the topend on that saw.

OK this winter I must get into my basket case 57. Not that I haven't had other interesting saws to work on.  All the lines are done but I was stymied due to a messed up crankcase gasket.  Thanks to Steve (brokenbudget) I have everything I need but the gasket.  Maybe I could just use Motoseal instead?

I actually ran across a NOS titan 57 last year. New lines all around, and new carb diaphragms and fired it up. Looking back, Iprobably should have kept it, but iIneeded the cash, so iIsold it. I sold them new back in the 90's, and they were a good running saw

If often makes me wonder what might have happened had McCulloch would have went to this design years before.However there was more to the story than saw designs.We will never know because the McCullohs I grew up running and the company is just part of history.

I have a couple of Titan 57 saws and one Double Eagle 50 put together, enough parts to make up a Titan 50 as well.  As noted above, the fuel and oil lines were made from whale snot or some other junk and will always need to be replaces and the coils are prone to failure, but the same coil was used on a few other saws, I just can't remember which.  Same goes for the plastic mac saws like the 32-38 cc models, same coil was used on a number of string trimmers.

Never let a coil failure cause you to believe a saw is gone forever or that you have no other options.  Many times you can find a similar coil on another piece of equipment and remove the coil and install it on the original laminations to make it work.  I'd have to do some digging but Ike Holts on another site was showing one (Husky 50??) that could be repurposed to 10 Series and SP105/125 saws. 

You might spoil one or two in the process, but you will never know until you try.

In regards to coil changeability it's a toss of the dice .They don't publish something like Hollanders interchange books for small engines.Cars yes,chainsaws no .

You would need a barn full of small engines to find one if you had no idea what might work .
