I've spent some time underneath Marvin today and I have two issues.

The exhaust is blowing at the Y-joint (the pictures shows the leakage) and although the exhaust still seems stable there is no attachment/bracket securing the exhaust system.

I've identified a bracket - Exhaust to Gearbox (1985 on) Manual (part number GEX7526) but can't find an image of such a bracket is attached (to the gearbox) and to the exhaust.

I've spent 20-minutes searching the topic on the forum but I can't find a suitable answer.

Does anyone have an image or advice?

Also, while underneath, I identified the gear change rod has lots of play where the 'bayonet' style joint where it connects to the gearbox.

Gear changes seem okay but I suspect it has far too much play.

Should this joint be loose and sloppy? I suspect not.

Thanks in advance.

Peter

Pipes not pushed in far enough. Don’t bother with any bracket there are they are gearbox wreckers. But if you must replace the bolt with a longer stud as the bolts are not available at a suitable length.

 

gears. The roll pins connected sleve? Yes they can be loseish. Not much you can do.

With the gear linkage, given what a PITA it is to drive out the roll pins , I would suggest you leave it be for now and do some research on the better options for the pins. I make my own system but you can decide on your best fix so when the gearshifts become troublesome you have a plan ready to go.

I bought one of these and found it very good. Saves distorting the seal in the box when beating the roll pins in.

Bolting the exhaust to the gearbox only pulls the threads out of the gearbox. Not a good idea at all.

Thanks for all the replies.

Great advice. I appreciate it.
