Question about driving shaft

[werewolf]

A little question.

The rubber boot (right aside of my foot, left side of the bike) is scrap (holes in it, rubber too dry), and I have to change it. Is it a difficult task to do? I mean, will I have to remove all from rear tire to the front exhaust pipes to change it, or it's a simple task to do, just remove the rubber, 2 3 nuts and then replace the boot ?

thx a lot, I'll learn ! =)

Its definately not going to be a simple job.Correct me if I am wrong, but you are either going to have to remove the engine and middle drive or remove the rear end (swingarm, rear drive, tire and rim) I am 99% sure that removing the exhaust is required. Trust me it isnt going to be that simple. Hopefully someone can chime in and give a step by step instruction on how to do so.

Give yourself a whole day to do it. Involves removing the back wheel and swingarm.

settle down guys

remove the bolts tht attach the drive shaft to the motor.slide the drive shaft back a bit,remove rubber.Then put new rubber on slide rubber back were it belongs.It's not real easy but can be done like this with pacients.I've done it on an xj.There is not a whole lot of room so work slowly and carefully.One hour tops

Chevy, I tried your idea once but couldn't do it - couldn't get the rubber through. I'm fired! Ended up pulling the swingarm. No real drama though - took 3 or 4 leisurely hours total.

How about a different approach?

Remove the rear engine support bolt/shaft, remove the upper front engine mounts/bolts, loosen the front lower engine mount bolts, loosen the header nuts, put a piece of wood and jack under rear of engine, loosen and remove the 4 nuts securing the drive shaft to final drive, then slowly jack up rear of engine allowing it to tilt forward in frame, puts the final drive a bit further away from the drive shaft, so you don't have to pull the rear wheel assembly. Then reverse to put back together. Just a thought!?

If you do decide to drop the swingarm you can then clean out the 25 years worth of grungy grease in the shaft unit. If you're keen , you can replace the 25 year old universal joint too. You can get them cheap from an auto suspension dealer. Quarter the price of the oem replacement.

I did a replacement on my XS850 by simply disconecting the shaft from the middle gear, then unbolted the middle gear from the engine case (9 or 10 Allens) and voila! Trick here is to have a replacement gasket for the middle gear to engine case surfaces, or gasket paste will work too. 1 hour top...

Remember to drain the middle gear first if you remove it from the engine. It makes one hell of a gear oil mess if you don't. DAMHIKIJD

thx a lot , all of you..

Is this rubber boot need to be filled with some grease or this boot is needed only to get away rain, dust and others unwanted stuff in ?

[strom]

The rubber boot keeps the icky stuff out... dust and things...
However... mine is still so nice, it even held the oil that the middle drive oil seal leaked thru...
I checked it once, pulled the boot back a bit and it was filled with middle drive oil.
Replaced the oil seal, cleaned the boot, greased the u-joint and off we went.

BTW: I got my yammie street legal... got a licence plate and everything.
Idle is a bit high after a longer ride, but I guess the carbs are set too lean. Gotta reseal the valvecover too.
Also both front fork oil seals leak (they are new) and one of rear shocks too. Gotta replace em. As soon as I find a decent set of konis on ebay.
Looks like the next thing is gonna be the tires... avon supervenoms.
