Shaft Drive Leakage

[Fiddlesticks]

Another tale of Explorer woe...

 

I noticed a suspicious oily mark under the back of the swing arm while the suspension linkage was out for it's highly irregular re-greasing.

 

Thinking that it might be the gasket that seals the final drive I went to the trouble of purloining a special tool to get the castellated oil seal holder unscrewed and set to work getting the rear diff off the bike.

Knowing it might be a long job, the first thing was to get the bike into a position where the garage door could be closed later tonight. Just the job for the turntable..

Getting it all to pieces was not too tricky, rear wheel, exhaust, brake caliper, speed sensor, gear linkage, torque arms...  

 

Sadly I think there's oil coming from the engine end, rather than the rear diff.

... Or maybe as well as.

Done for tonight.

Well, it's all back together via a brief excursion into one-up, five down gearing.

 

In the end the rear diff was seeping just a touch, but the thing was solid - needed a breaker bar extension and a second pair of hands, neither of which were available.

 

The bigger issue is the oil seal around the output shaft splines from the gearbox. How much of an issue? I'll keep checking the inside of the front gator to find out.

 

Looks like it will have to be fixed from the inside. I'll have a chat with the mechanic, it's getting beyond my comfort (and patience) zone.

Looks like someone tried to get the seal out previously.

[Fiddlesticks]

Maybe so. Needs heat to break the threadlock, followed by a lot of vertical and axial force.

 

Edit - Ah, sorry, I think you mean the one from the gearbox. Yes, I agree.

Be easy with the right tools

 

 

But I bet the right tools aren't cheap!!

I know from BMWs , contrary to belief I see loads of them having that and bearings done in garages regularly,  its a mechanics rating of “7-8” of a pain in the arse for a “simple and cheap part” to fail but yet requires so much ball d1cking about to get at it, fix it and put it back together and hope it doesn’t weep again shortly.

 

Good luck and hope you sort it out soon and cheaply.
