Finger tight and the thrust washer

[NorthernEdge]

I changed the chain case oil last night and as I was tightening the chain I realized I don't know what finger tight means. Does it mean as tight as I can with with my fingers or does it mean until I meet resistance? I asked on FB and I called two dealers, the answers were split right down to the middle. I figured I was going to get blasted.
Last (for now) but not least, I assume I just put that thrust washer that gets stuck on the case back on the middle shaft and it will work it's way into position?

Yes put washer back on. For chain tension back the rubber washer off and turn it in with two fingers tight then back off the 1.5 lock it down holding position of bolt and dont think about it. 1.5 is way more than enough slack and the spring on tensioner is whats actually doing the tension. You checked tensioner for loose bolts I assume?

The spec of 1.5 IMO is from the old rule book.....TCL and all.

I used to to 1 turn out, but now am at 3/4 turn out. I did this all while actually watching the chain and what is going on. Even at 1 turn out, the chain can touch the center post and grind alum in certain conditions. We have seen this many times. Possibly issues of not going into reverse have not affected mine at all at 3/4 turn out.

I tightened mine as hard as I could with fingers, before loosening.

Dan as far as I know TCL never was used with a manual adjuster. I think 1.5 is cautious but some people have real strong fingers I guess. I go 1 turn back and never a issue other than top gear bushing every year. I do know that at 1/4 turn back like Yamaha used to be there is big time whine from gears. Probable good anywhere in between.

Yeah I thought there was a few seasons without auto adjuster, like early Vipers maybe? And it was cat simply bring over the language(from manual) and not really thinking about the fact they could be tighter without TCL.

I hear ya with the whining.....We certainly need to keep tabs on these chaincases for sure.

Older video I did last yr....Now this video is with a 22 top gear so you can see less dogleg and chain is not even close to center post....But you can see the tension when set to 3/4 turn out.

I would never set it tighter then 1.5 turns out, that tensioner is spring loaded and you preloading it to help set the spring and then actually are backing the tensioner bolt off completely. Its only there in case of the chain deflection is to great to not keep the chain engaged on the gears. If you hear whining then you will kill the bearings thats for sure.

Disagree....

 

[MrSled]

Disagree....

Good luck with that. I have taken out chain cases our because of wrong spec. So you take on the responsibility and whoever else follows it.

 

[Fleecer]

I'll settle this argument:

Mr. SLED states 1.5 turns out from finger tight. Rockerdan states 1 turn out from finger tight. When I serviced my chaincase this fall, I didnt want either of these gentlemen to be mad at me, so.........I settled in the middle and went 1.25 turns out from finger tight.

Boom....argument resolved and everyone is happy!! Lol

LMAO, no arugment here. Do whatever you want but the spec is 1.5. I have better things to do like keep the damn hackers from the sites resources.

Dan your stm 60ys ramps,are they the ones that are close to the stock Yamaha ramps for curvature,kinda flat vrs stm ramps that mimic Dalton shape? I really like the cat 22 top for less dogleg,and we set mine at one turn out from very tight finger.

Suppose to tighten 5lbs then loosen off 1.5 turns,running it at 1 turn noticed silver in the chain case the spring is suppose to keep the tension they say its harder on the roller any tighter
