Rear wheel bearings - car type wheel

Post by BSA » Fri May 10, 2019 10:35 pm

The NZ Triking has been on the road since August and has now done about 12,000 km, daily drive if the weather is kind.

The rear wheel is the car type supplied by Alan, using the donor guzzi cush drive rubbers etc and spacer tube.

Alerted by a clunk from the rear end, I found that I had run the rear wheel bearings. On investigation I realise that I have failed to check the length of the guzzi wheel bearing spacer against the distance between bearing housings in the Triking car type rear wheel.

The spacer was .4mm shorter than the distance between bearings, meaning that when the rear axle was tightened a thrust load was applied to the bearings, causing premature failure. Sorted with a couple of new bearings and a longer spacer.

Just a reminder for any ‘new builds’ to measure before assembly.

Good point BSA perhaps it is something to put in the next Trifles Newsletter for Triking owners.
