Drive Train Backlash - Rear Mudguard

Post by Weg » Tue Sep 21, 2021 8:00 pm

Decided to strip out the rear end to investigate backlash in the drive train.
Nothing serious but the swinging arm bearings had started to see the effect of 20,000mls with no mudguard under the boot.
Taper roller bearings and seals replaced and packed with grease, details of greasing maintenance provision to be explained in another thread.
To prevent future deterioration, I fabricated a rear mudguard (which I should have done when I built the car) using 1.5mm ally tig welded down the seams.
Double thickness reinforcing plates welded in where fixing occur.
Hinged in the middle to give easy access to rear wheel by removing 2 bolts on the rear s/s strut.
Lower front mountings were welded to the swinging arm while it was removed.
On re-assembly of the drive train, I packed all the spline with Chain Soap (used to be called Linklife). It’s very thick so hope will stay on the job for a while.
Road test has revealed a marked reduction in backlash rattle. Time will tell if long-lasting.

I like it. I might have to borrow that design and build one this winter. Nice work.

Thank you for sharing, I have been looking at options for retrofitting a mud guard on my type 3

For an alternative non welded construction but using a shrinker, glued and riveted:
