Tranny Trouble AHHHHHHHHHH

[Scoooter]

No I haven't removed all the clutch components yet. I stopped after I noticed all the slop on the rack release. i plan on taking the clutch the rest of the way out shortly

[Scoooter]

Ok I removed the springs and cover, all disks, and am now stuck on the center nut, so far all components look fine

[BadBillyB]

Getting that nut off can be a challenge if you dont have an air impact. Resist the temptation of holding it by the bosses that the clutch springs screw into. They will BREAK...I bought a 78 GS1000 last summer that had a rattling basket in it. I knew that it needed a basket in it when I bought it. When I tore it down to replace the basket I found 5 clutch springs in it and a broken boss where the 6th clutch spring bolt would have gone. Somebody made an attempt to pull the basket and made a mistake.....Do you have use of an air impact???.....BadBillyB

[Scoooter]

Yea I have an impact gun. Not so sure the basket is the problem thought, everything is tight and has no play:? I am starting to get frustrated now, I just want to find the problem so I can get the parts on the way

[Scoooter]

I just went out and was going to take off the clutch and check the basket abd then pull the motor. I put the chain back on so I could take the clutch nut off and spun the inner clutch hub(one that the disks and plate slip over) and it has like close to an inch of play before it the back wheel catches, and also it makes the knock noise. So wonder which part is defective???? Please help, ready to take out offending part and order new stuff

You may have problems with the "dog cam" on the countershaft gear assembly.
The dog cam spring retainer has broken twice on one of my 850 motors.
When this dog cam assembly failed, the bike would act as if it was jumping out of gear and make a horrible rattle/grinding sound. This would happen when going through the gears in a "spirited" manner. It also had alot of "lash" in the driveline.
To fix it required disassembly of the transmission. Cost about $80 in parts (new spring, retainer and spacer)- doing labor myself.
The second time it happened I just bought another good running engine on ebay for $150.
I have since quit pulling holeshots and doing powershift second gear wheelys and my trannys are holding up lot better.
I put an exploided veiw of the countershaft for an attachment.
Good Luck!

Thx alot, I went out in the garage and started stripping the bike down. Everything is off and the engine is just sitting there waiting to be lifted out. Split the cases tomorrow after work so I can see what the deal is.

If you turn the center hub back and forth left to right it will make a noise. This is normal. The inch of play, is also normal as the receiver slots on the gears is much wider than the engagement dogs. Try taking the chain off and turn the inner hub counter clockwise in a smooth and continuous circle. It should be very smooth. No clicks, pops or binding.....I think your jumping the gun by pulling the motor at this point.....Even if you pull the motor you will still have to take the clutch basket out, might as well do that now.....BadBillyB

He has a chain not a shaft drive. Transmissions are very different....BadBillyB

Well we split the cases tonight. Things look great inside with the exception of 2 things I noticed. On the sprocket shaft, The last gear which is on the clutch side has some play in it, 1/16 I would estimate, slides from side to side, not checked into it further till tomorrow, and the small gear that is behind the clutch basket(has a clip that holds it to the shaft and goes into a small housing) looks warped when you spin it, its very noticable. So I suppose that is where the vibration is coming from. Everything else looks good as new:?

[Scoooter]

What is the small gear behind the clutch basket called? I can't find it on bike bandits exploded views. It is on a shaft all by itself.

Oil pump driven gear.
