Overhauling the engine gives an ideal opportunity to check out the transmission?
Check all the major components for wear or even damage while you have the window of opportunity available. It could be a colossal waste of time and effort to carry out a successful rebuild of the engine only to suffer a noisy, or unreliable gearbox after reassembly.
If some parts are found to be worn or damaged then this component and possibly some of those listed below, perhaps also parts interfacing with the damaged item, may end up in your shopping cart.
Add as many components as you wish to the same shopping cart, new thrust washer 0821120321 & circlips 0938025003 for example, and still only pay the same single fixed price shipping cost.
