550XP loose crank stuffer.

[Mark_Skyland]

Got a 550 in for repair which has had a mild seize. Fortunately the pot is in very good condition and needs next to no work unfortunately one of the crank stuffers is loose.

 

Is there any movement allowed, and does anyone have any experience in using a saw that has this issue?

I rebuilt one of my 560's and noticed the crank stuffers were loose , I did put it back together and a few months later the stuffer destroyed the saw!

MattyF had a 560XP that stripped the outer stainless cover on one stuffer, needless to say it did some damage but he rebuilt the bottom end, I ground and fettled the top end, Burrell machined the piston and it ended up fully ported, muffler mod and pop up piston - still running a year later:thumbup:

 

The stuffers are usually a snug fit and don't believe that they should be loose but never really prodded them about TBH!

What did I say...............thought Matty would be down the pub:lol:

I have seen some with loose stuffers with no ill effects, i have never seen one come apart and damage the engine.

Can't say hand on heart it was due to it being loose but here it is and the damage was pretty bad but we got it going again!

Major issue on hard worked saws , 3 560 bottom ends on the bench this week , 2 have stuffers with hairline cracks , stacks of play in them .

I got a whole bottom end short block for £180 I did try and rebuild with a crank off an a 562 but the crank was the wrong size for the clutch Off a 560 ,which reminds me it needs to go on eBay.
