Hi Em and Smelmechiz,
In all honesty those clutch bearings are quite robust and really don't do that much work anyway.
If the machine it came from hasn't been left out in the rain over long periods of time you'll find that a removal, good clean and re-lubrication is all it will require and thus it'll do many more hours worth of work, also they ain't cheap in any case.
The clutch body as em suggests is a very important part of the driveline and must run totally true to lengthen the life of the chassis and as you have a twin railer which is far more susceptible to stress fractures than the one piece Solid deck versions you must preserve it the best way possible. If the body shows any left and right movement while rotating the engine via the starter cord you can consider it either a throwaway or have it sleeved for reuse again.
Cheers,
BB.
PS. Thanks for your very kind words Em.
