Yam_Tech314's official build thread

Looks like it.

Yes, as long as you're using a non-hardening sealant, you can wait as long as you please.

Better question for you. (Or anyone really)

Is this JB weld job gonna cut it? I know it probably wasn't necessary but I wanna cover all my bases so I'm gonna let it cure overnight. Will the tiny lumps prevent the seal from sealing properly in the groove?

As an info refresher, the chain threw in the past life of the motorcycle, and cracked the cases by the clutch pushrod seal, so now I'm working on preventing leaks before going forward despite my excitement.

One more stupid question... But should ALL the seals be flush with the outside of the cases upon install? I instinctively wanna press them in as far as they go... But the old ones look like they were flush.

When time comes to yamabond this guy together, are there any spots I should coat heavier? Such as the clutch side of the crank? If this thing leaks I might actually cry lol.

If I am correct, the sprocket will eliminate the side play on the output shaft, and the clutch pushrod seal should eliminate the play on the other shaft, correct?
 
Correct.

Not correct. Clutch basket will remove that play.
Cool. As long as I know there's something there to eliminate it...

As far as sealing the cases goes, the directions tell me to thinly brush it onto the mating surface. I only need to brush one side yes? The other side is real close to crank and bearings and other components I'd rather not mess up.
 
Is the output shaft supposed to have side play? Mine definitely has a good bit of it.

Interesting. I've not noticed much out put shaft side play in the past while changing chains and tightening the front sprocket. Curious about the amount of side play and the reason?
:popcorn:

The moment I put the sprocket and bend washer on, and hand tightened the sprocket nut there was ZERO side to side movement. I dunno! Lol as long as it's solid now I'm happy. I don't recall there being play when the motor was together even when the sprocket was off, but I got it to sit in solid.
 
That play is what we're adjusting when we adjust the worm screw, yes?
Nope. The play I'm referring to is pictured

The play you adjust with the worm screw is the distance between the worm gear and the pushrod itself if I'm not mistaken.


The side play I'm referring to is this:

I'd do a wiggle video but that requires uploading short clips to YouTube and it's not really worth it.

I only put it on one side. Putting it on both is usually too much sealant that will squeeze out everywhere and make a mess.
 
While I have people's attention... I have more side play questions!

Is there any kind of washer or spacer that goes here? And do I even have it in right? When removing the outer gear the inner gear fell off the shaft and since that was a year ago now, I can't confirm no parts were lost.

Use your IPC drawings.... no, no washer. Yes, looks correct.
