WANTED OEM 064 Cylinder

[jacktheripper]

I think my cylinder might be worn out. New rings, .027 squish, only 140psi.

Let me know if you have one.

Are the rings brand new, or have they had a chance to break in?

I was hoping it was a break-in issue, but it doesn't seem to be. I'm about three tanks in and still no improvement.

Is the plating worn through? Can you resize some over bore rings?

Plating isn't worn as far as I can tell. I was thinking about finding some bigger rings and filing the gap. Does anyone have a suggestion on a set of rings for it? Oversize 52x1.2mm I guess?

Caber rings?

 

[jacktheripper]

Caber rings?

Yep.

 

[huskihl]

Yep.

Cabers take 10 tanks or so to break in. The plating isn’t very thick and is usable as long as it’s not worn through. Was the end gap excessive on the new rings?

 

[huskihl]

Could also be an issue with your tester. Maybe try another saw and see what it reads

 

[Nutball]

I assume 140psi is low for what your particular gauge normally measures on most saws, right? I found 150 and 165psi for a stock 064.

That is what I was gonna say

 

[jacktheripper]

Same gauge was reading 190psi on my 5105 and 195 on my 266. I just haven't had this issue with long break in with Cabers before, but you may be right. Unfortunately I didn't measure end gap, just ball honed the cylinder a couple of passes and threw em in there. I do take into account that I'm up at 5800 ft, so 140 would be more like 160 up here

I have had some Cabers take even more (like 15+ tanks ) to notice break-in. I would consider 150psi to be normal for that after break-in and I’m at 850’.

Any jug pics?

Agree with all of the above. Caber F-cast take even longer to break in.

I'll tear it down and take some sometime soon. Maybe I'll just run it and see what happens after a few more tanks too

Is this one of mine? I should still have pics

 

[jacktheripper]

Nope, it's actually the saw that got me into saws. My good ole trusty

How worn is the piston?

 

[jacktheripper]

How worn is the piston?

Not worn. It's a new Meteor. Very little slop when in the cylinder.

What altitude are you at?
