064 cylinder

[Totembear]

I've got a post in Tradin' Post but I thought I might post here to. I need a cylinder for my 064. Either that or an early 066 with 5mm bolts. I wouldn't mind Meteor or tecomec but I think they make them with the 6mm bolt holes only. Any advice or offers would be extremely helpful. My BB experiment lasted about 5 minutes ending up with a scored piston. Should have gone with the 066 cylinder. Oh well, live and learn! Thanks.

We rebuilt one recently wirh a jug and piston from a shop called Lil Red Barn.

Why did the Bb kit score? What happened to your original P&C?

If the saw has a problem, you're just gonna keep ruining parts and wasting money.

Just askin.

I wonder if you could sleeve the bolts? If the 5mm jugs are impossible to find, it wouldn't be a hard job to weld the 6mm holes closed and redrill, or to just drill out and tap your case for the 6mm bolts. You won't have to worry in the future.

^-^-^ What @drf255 said , make custom bolts with 6mm sleeve and 5mm threads!? ^-^-^

To make sure You have good quality bolts You could use OEM 6mm bolts and narrow/re-thread them to 5mm.

The original P&c were scored. I got it in a lot of 6 chainsaws from a landscaper that ALL the Pistons and cylinders were burned but seals, bearings, etc. we're fine. I rebuilt them and they are cutting wood today. There are two marks on the piston and cylinder, pretty deep, that I've got the feeling that it caught a bur in the exhaust port and scored it. When I built it it ran fine, ran fine to cut the 36" piece of wood, but when I got done it cut out. It did take about 7pulls to get it started, so it might have been scoring all along. Wouldn't start as the piston was caught on something. I hear ya, and I might have to do that, but I'll look for a cylinder for a while. The reason I got this BB kit is that I'm impatient, and now I'm out $100. Good things come to those who wait, or so I'm told!! If I do decide to do it, I'm going to have to give it to a machine shop, no good at that kind of thing! It's a real nice saw!

How did the one from the lil red barn do? Is it cutting close to OEM? I'm real hesitant to go with aftermarket anymore if it's not meteor or tecomec.

Someone with a lathe could make custom bolts in a matter of minutes.
Turn down the 6mm thread and thread on the 5mm one - four times.

Another case proving bad beveling on AM P&C kits can be a deal breaker!
Acceptable bang for the bucks only if thoroughly inspected and reworked if necessary.

 

[Totembear]

Are you saying to leave the neck 6mm and cut the rest down to 5mm? Or cut all the threads to 5mm?

It is so easy to rethread the chassis to m6 and do the bit of slotting required to install an 066 cylinder on these saws that keeping them standard 064 is just for the purists. The increase in power and much easier to find 066 P & C sets make the conversion well worth it.

 

[Totembear]

I like the idea of going with a 066 cylinder, easier to get, it's just when it comes to machining I'm challenged in that area. I have a close friend who's a machinist by trade who I will run the scenarios by. My only question with machining the bolts down to 5mm is is it a stable platform for the cylinder?

 

[Deets066]

Instead of machining the bolts down just tap the bolt holes in the case to 6mm as pioneer guy said above

 

[blsnelling]

You don't need to do any machining. Simply drill and tap the case to 6mm.

 

[Totembear]

Ok. I will tell him what I want to do. Better in the long run I suppose. This 064 better last me a long time as much time and effort that I've put in to it!

 

[pioneerguy600]

LOL,...You havn`t even scratched the surface of chainsaw building. Wait til you have stripped that saw down to the last possible removable part, washed and cleaned each part by hand, inspected every fastener and fastener hole n threads, rebuilt it that way 3 - 4 times total replacing every worn part, gasket and rubber pieces. Then you can say you put time and effort into that saw.....LOL

I would re-thread only as much as goes into the case, plus a little spare length of course.

-OR-

This would work too, keeping the bolt stronger altogether!

I see you enjoy becoming "intimate" with your rebuilds, too.

 

[Totembear]

Yeah. I've stripped down saws, pulled the crankcase apart, rebuilt it, had to tear it down again because I left a simple but necessary part out... I've got to the point where I feel comfortable going Down to the barebones and building her back up. But I'm still on the learning curve to what works, works good, and works better, lol. It never ceases to amaze me how many different parts can go on one saw. Case in point: mine has got the dogleg coil on it, holes for it are not drilled like a standard coil, but some of them got the standard coil, and some of them have a different coil than either of them two. It was a little while before that one sunk in. The only coil I could find was at a local dealer for $145. Plus odd accessories and I know I've got some money in that saw. But, I want it right and pain is the cornerstone of spiritual (and monetary) growth! Lol as always, you guys are the greatest!

 

[Totembear]

But a question: you said a bit of slotting, what do you have to modify besides the bolt holes?

 

[Totembear]

I might have to take my friend to my hunting honey hole as payment! Lol
