Title: Cali drive shaft coupling
Post by: Mr Revhead on May 23, 2017, 01:04:07 AM
Took the bevel drive and swing arm off the other day. Looks like someone forgot some grease!!  :angry:

Looks like i'm lucky with no wear. However that coupling is stuck on the shaft.

Before I start getting creative with my techniques I want to be sure I have this right:

12 is a press fit into 14, which in turn is a press fit into the swing arm. So that assembly comes out forwards.
7 should slide off nicely out the back?

Currently spraying penetrating fluid up the shaft which I'm keeping vertical so it can run down the splines and hopefully free it up  :huh:

Your right on the parts diagram on how it comes apart. I can figure out how to get it apart, how do you get it pressed back together with the U joints?

I'm not removing the U/J's or bearing, they are fine. I want to free up and lube the coupling. So just making sure I have the right idea with how it goes together to make sure I don't bugger something.
I wonder if Guzzi will still honour the warranty  :Beating_A_Dead_Hors e_by_liviu

The bearing and shaft should not need any presswork.  Firm but gentle persuasion should do.

#2 in the diagram is a grub screw.  It holds the carrier bearing in place.  That's why it's not a press fit.  Find it, remove it, and drive the entire driveshaft/coupler and bearing out the front.  Then you can heat the coupler and knock it off the splines.

The coupler, #12, should slide right off the back of the driveshaft.
I have had it freeze onto the back of my 2004 EV a few times. I soak it for DAYS in penetrating oil. I made a hook that I hook onto it. And I try to get it hot. It takes a lot of work but it eventually comes out.

I have yet to find a grease that stays in place and prevents rust.

Someone told me that the grease Honda use on their splines is pretty good

From the boating world works great.

Totally missed that grub screw!! Thanks for that! See that's why you ask before using hammers  :violent1:

I have the moly grease Honda use for my CX500. It's for splines and high pressure/shear use. So I'll use that. It's quite thick and sticky
Thanks guys!

If you mean the Honda Moly 60 paste, it doesn't do a thing to slow the rust. I didn't have much luck with it alone.

I tried the Honda moly 60 also. It was gone shortly thereafter. I've been using Wurth for 20 years, and it's always there. Never have had a rust problem.

Hmmm I'll have to have a dig around then. Wurth is extremely over priced here.
Sounds like this spline should be lubed every Tyre change or yearly

Bang on. Well, I banged on it with a section of broom handle as a drift. Out it came! The u/js and bearing feel fine so it'll go back in again. After I've cleaned the gunk out of it. Gearbox out put was leaking
