Cheep things are expensive. Such as this 2008 C50 Tramp. That said, it appeared to be low mileage; where it was stored featured dust accumulation with no signs of leaks under the cycle, and the differential case did not show signs of leaking. Changed the motor oil, drove it home 550 miles- and the front of the differential case and, slightly forward, a brake cable are covered in what seems to be oil.
So, now I get to learn all about rebuilding a differential.
Along the way, I left the parking brake on a couple times. Could this have taxed the differential to seal failure? The trike seemed fine while I was riding- do you reckon that means the gears in the differential are still intact?
I’ve read that Lehman attributes some differential failure to certain batches of faulty components- is there any way to identify if this differential includes those parts?
Thanks for your consideration.
