M32 / M20 Gearbox Bearing Rebuild Kit (M32 Bearing Pack) for M32 and M20 gearboxes with early end case.
Usually up to around 2012 (unless late end case upgrade has been performed)
Bearing Kit and Seals for M32 and M20 Gearboxes as used in Astra H, Corsa D, Meriva A, Fiat models including Croma and Punto, Alfa Romeo.
M32 gearboxes can be prone to noisy bearings often caused by poor quality gearbox oil which is often left unchanged. Heat build up in the gearbox causes the oil to go out of grade reducing its protection and causing premature bearing failure due to loss of bearing lubrication. If left the bearings can break down and then cause further internal damage. At the first sign of noisy bearings it is advised that the box if inspected and repaired/bearings replaced at the earliest opportunity, to prevent further more costly damage.
Bearings are manufactured by GBC, NTN-SNR Group (SNR Bearings) and The Timken Company (Timken Bearings), Leading Automotive Suppliers to the Automotive industry as OE (Original Equipment) and Aftermarket.
There is an input shaft diameter difference with a change around 2008.
M32 Up to 2008 Input Shaft Bearing/Seal 27mm M32 After 2008 Input Shaft Bearing/Seal 25mm
There can be an overlap/slight grey area on the input shaft bearing size, generally the change occurs during 2008, so included are both sizes of Input Shaft Bearing and seals which means you do not have to remove your gearbox first to check which size you need.
This kit can be supplied without differential bearings if they are not required, for example an LSD has recently been fitted and the bearings were replaced with the LSD.
This kit is for the earlier type M32 and M20 with the earlier end case. The early end case is identifiable by the oil level check plug at the front. There is a later type M32 / M20 gearbox in circulation with different end case bearings for which a different bearing kit is required. To identify the later type of end case it has no level check plug and additional oil galleries to the bearings. If unsure please contact us.
Clearances should be checked during rebuild and shimmed accordingly. Shims available separately as required.
