Title: Leak underneath LT
Post by: Dermy on June 14, 2016, 03:43:03 AM

Hi guys

Had a tiny leak.
Then I started to move the rubber seal now I have a proper leak.
Where is this coming from and what do I need to fix it.

Is it safe to ride or will it do more damage.

Thanks guys

Clutch push rod seal.   If it is not torn,  it is at least unseated from the arm at the small end.

Item #6, clutch boot, about $42.

Like was mentioned, if it is not torn, you should be able to re-seat it. If not then a new one is in order.

There is supposed to be some gear box lube within the boot to lubricate the push-rod "piston" aka throw-out bearing....

Would it hurt to ride? Not really but that's your call. It's only going to drip oil into the path of your rear tire.......

Replace the boot as Scott_ and Marshall have indicated. You could try to attach a small can under the weep hole to catch the dripping oil for resale as a mosquito control in Belfast but the licensing of your recycling business would probably be more trouble than just the repair. It's good to see, though, that you're not letting sentiment get in the way of reusing materials. Our planet thanks you!

It looks to me like the coolant tank has sprung a leak a the bottom of the overflow tube (cracked at the clamp) and coolant has run down the gear position wire onto the clutch seal, where is it now dripping off.  kb

Hi

Definitely not the coolant.
Rubber seal is leaking oil.

I've ordered new parts.
Just need advice on how to change it.
I'm a complete novice on mechanics

Thanks

Pick up a Clymer manual then pour yourself a couple of drams and watch this 5/6 part video. It will explain removing the clutch cable from its lever, adjusting the sidestand lever, installing the boot and a number of other important maintenance items. You won't need to strip your bike down to the extent shown in this video but it's an education in various procedures and may help clarify instructions in the manual. If nothing else it'll be entertaining.
