In Mororcycles, we are told to replace the sprockets ever time we
replace the
chain ('cause it is the increased spacing of the sprockets (due to
wear) that
has caused the chain to stretch). Is the same not true for the
oil pump
drive chain? In the video, bruce measures the laxity of the chain
(mine
measure the same his did) and replaces it, but no mntion is made
of the
sprockets.
There is no visible wear. Does anyone know if they need to be
replaced?
Does the oil chan really need replacing? Everything else in the
engine is in
good shape, havent heard of many engine failures caused by chain
failures...
but sure would hate for those to be 'famous last words'...

The chain wears on the rollers and the pins. Take a new
chain and bend it to one side with the end plates verticle. Now do the
same with a used chain that you think is not worn. Surprise!!
