final drive replacement

Post by 86 goldwing »



just picked up the final drive to day
now its time to tear bike apart again to replace the housing
so was wondering if the drive shaft can be left in the u joint when i pull the bad FD out as you can see in the pic the new
FD did not come with the shaft


if i can do this how do i keep the drive shaft in the u joint when i pull the FD off the bike
thanks for any info on this

I think what you're asking is will the shaft come out with the drive and the answer is, probably. They can be a little difficult to get back into the u-joint but it just takes figuring out how you will keep it elevated at the end you can't see or touch.

thanks Dennis was hopping i could grab the shaft through the boot and hold it will i pull the FD out at the four bolt joint
but i guess that wont work
read one of the posts that if shaft is moved to much or removed it will start to leak oil at the u joint end
was hopping to avoid that issue

To put the drive shaft in the u-joint, I take the u-joint boot off the engine, pull it back, drop the u-joint off the engine and fit the drive shaft to the u-joint on the same level then put the u-joint back on the engine and push with the drive shaft. As with any issue with the GW, works 99% of the time.

No issue with the seal on the drive out the back of the engine. The seal on the drive shaft will be good as long as you ease the FD on the swing arm.

ok good to hear that is one of my main concerns dont want to put it all back together and find an oil leak and have to start all over again
going to start on it later this morning and see how far i get without any help
have to work on wednesday then off on thursday and back to work friday so might not be done until weekend
so might tkae a little longer than most people do this
have heard that it only take a couple hours to do but
i have a large group of gremlins that just wait for me to start working on the old girl
and they really enjoy messing with my tools and parts
will keep all of you on site as to my progress
thanks for all your help

just throwing out a big thank you to all of you who replied to my posts about the final drive
if it was not for your replies and advice i would still bet fighting with the drive shaft
tried just fitting it to the u joint with no luck then went with the idea of the 1/8 shim under the u joint and the shaft slipped in like butter
drive shaft final drive tire and rear brake all back on hard stuff over with
now onto rear shocks lower light bar with trailer hitch attached rewire all the lights and then saddle bags and i should be on the road either
thursday night or some time saturday
thanks again to all of you on this site
