use the thrust washers you made , donot run saw without them, I have seen a couple motors guys didnot use the washers and figured the rod being centred on the crank would work, it didnot . I donot use thrust washers to the big end and only use the 084 rod , never ever had a problem

I'm talking the thrust washers on the piston end not the big end , I always put a new stock 3120 bearing on the big end when stroking and changing to 084 rod , to put thrust washers on the big end they must of used a narrower rod bearing

Ed, You're right.  The big end bearing I sent them was a high quality silvered bearing but slightly narrower than the Husky bearing.   Didn't think about that being the issue.  Thks

Al, I remember you made some for Cliff?   We're they flat or scalloped to allow more oil to migrate into the needle cage?

They were just blanks .I don't know what he did with them .I had the ID and OD right on the money but left some meat on the length so they could be fitted at how ever much clearance he wanted .

If I recall I made several blank  sets and Kevin might have ended up with a pair on that 3120 hottie he had .

Good deal Al. I made a batch and cut four radial slots 9,12,3 and 6 o'clock with a ball end mill to let some more oil into the bearing. Probably not necessary, but...
