swing arm question

[ahoward125]

First... I did a search on this and found differing opinions.
I need to replace the seals on the clutch shaft.
Can you pull the swingarm, bevel box, and rear-wheel as a unit?
Roll it away, replace the seals, roll it back,
Bump the motor to get the splines to line up
Re-install swing arm as a unit.
Yes, I am a lazy sod and want to get this over as soon a possible.

You'll find that you will do more work trying to get out of work then just doing the work.

I need to replace the seals on the clutch shaft.

Which seals ?

I had no problem with the rear wheel and guard removed, swinging the swing arm backward complete with the bevel box back off the shock absorbers.
Swinging it back in, engaging the splines was easy then putting the pivot pins in by myself.

I am sure with two people what you want can be done easily but comes back to the seal you are talking about.

Clutch pushrod seals...

Getting the swing arm back in works best having it angled with the rear of it near the ground so if the wheel is on you can't do that. If you try with the swing arm parallel to ground it's difficult if not impossible getting it in the frame brackets to put in the pivot pins.

Clutch pushrod seals...

Remove the wheel, pull the swing arm rearward.
Needle nose pliers will get to the push rod.

That area has nothing to stop crud getting to the plunger, I cut up a clutch cover (Ducati) to make a bellows/seal while I was there.

That is my experience, too.

You have to take out rear frame rail upper bolt or it won't go in. That would be the rear one for foot peg mount.
I use a tiedown strap over fender/frame rails, hooked on shock mounts on rear drive & swingarm.
Adjustable AND you don't have to hold it, you can swing it in & out.
Just did this day before yesterday on LM5

This site is the BEST...
So I remove the rear wheel, and only pull the swing arm back, but not off completely... excellent!
Needle nose pliers will get the shaft out.... OK (I am bummed that I left all my reference books at a different location.

Now ya tell me about the custom throw-out-shaft boot - a week after replacing the clutch. At least it's something I can do without undoing the swingarm.

Which bike?  On my Quota, I replaced those with the rear wheel on, swingarm as-is, etc, I could get the pushrod seals out and replaced.  Just remove the clutch cable from the arm, and then there was room to get the clutch arm off, and pull out the push rod from the back. 

Do other Moto Guzzi's have room for this like the Quota?  Or was I just fortunate? 

[malik]

Fortunate! On the smallblocks, there's a couple of problems. Firstly, there's not much room at the back with the swingarm on - it's a lot easier to acces with it off. Secondly, the clutch pushrod seal lives in a recess in the rear of the clutch shaft, so to replace it, the clutch shaft has to come out - gearbox off, clutch cover off the transmission cage. Oh, frabjous joy - I've another one to do.

On a Eldorado (1973) the swing arm pivot tube would be in the way to removing the push rod from the bike.
If you were one of those folk who build ships in bottles it might be possible to work in the 30 mm gap but why bother.

I used the recommended O-rings instead of the OEM push rod tapered rubber collars.

With the swing arm back or out you could lubricate a few things while you were there ( I left the shocks in place and the SA pivoted on them, the rear guard/fender was not on the bike either)
