M32 Gearbox Updated Endcase Shim Upper and Lower Mainshaft 24461954 1.30mm

M32 GEN 2 Gearbox Updated Endcase Shim 1.30mm – Upper and Lower Mainshaft – OE Part 24461954

This is the 1.30mm endcase shim for the upper and lower mainshaft of the M32 GEN 2 gearbox, OE part number 24461954 (fitment positions 31 and 56 on the M32 exploded diagram). This shim is required when fitting the upgraded endcasing on M32 GEN 2 gearboxes and is used during gearbox rebuild to set the correct endplay. This product fits all M32 GEN 2 gearboxes — it does not fit the first generation M32 which uses a smaller endcasing.

Important: The correct shim thickness can only be determined during gearbox assembly by measuring endplay. We are unable to advise on which shim thickness is required prior to disassembly — this must be established during the rebuild process.

Does this shim fit all M32 gearboxes?

No. This shim fits the M32 GEN 2 gearbox only. It is not compatible with the first-generation M32 which uses a smaller endcasing. If you are unsure which generation your gearbox is, please contact us with your vehicle details.

What thickness shim do I need?

The correct shim thickness is determined during the gearbox rebuild process by measuring mainshaft endplay with the new endcasing fitted. This measurement cannot be pre-determined — it must be established when assembling the gearbox. We are unable to advise on shim selection in advance of disassembly.

Why is an endcase shim needed on the M32?

The M32 GEN 2 upgraded endcasing requires a shim to correctly set mainshaft endplay. Without the correct shim thickness, the gearbox may exhibit noise, rough gear engagement, or premature bearing wear. Eco Torque is one of the first UK companies to offer the M32 bearing and endcase upgrade.

What positions on the M32 diagram does this shim correspond to?

This shim fits positions 31 and 56 on the M32 exploded parts diagram (upper and lower mainshaft endcase shim positions).
