you have read the threads , on other forums , here is a picture of an 8v cam and followers .
A distinct lack of grease from new…these are going to be a problem for every owner. The problem will be compounded by other problems that you are trying to fix at the same time .
This needs to be a job on it’s own, because you will end up doing the knuckle underneath at the same time .
Parts involved , knuckle, swinging arm bearings , seals for bearings , swinging arm spindle …and if you are really unlucky …a swinging arm .
Getting the rhs bearing out , means grinding/cutting the inner race as the output shaft from the gearbox gets in the way of a puller , and the shape of the hole and frame stop you getting a drift on it from behind .
In my profile picture you will see a Moto Guzzi California II in white, this bike came to me with a knocking noise which started from around 2 thousand revs and stopped around 3.5 thousand revs. After a road test. I found the issue by stripping the engine and checking the con rods. The rods were egg shaped worn. This caused the bike to make the noise.
With a engine out of the frame, second hand conrods, machined crankshaft to oversize shells. The bike was brought back onto the road.
This bike had been seven years parked up so it was good to see a happy customer able to use the bike as it should be. No nasty noises and back out, on the open road.
