SOHC (and LS DOHC) Camshaft Bevel Shim - Various Sizes (Each)

Essential when rebuilding your SOHC engine to ensure that the upper vertical bevel gear has the correct backlash and position in relation to the camshaft bevel gear, these camshaft bevel shims fit between the camshaft (the rear of the shoulder that holds the large bevel gear) and the front cambox bearing (i.e. in the front cambox well).

Fitted in conjunction with the upper vertical bevel gear shim, the ideal positioning is acheved when the gears are in line and there is a just perceptible gap (backlash) between teeth (and see our listings for lower bevel gear shims for more information on the full Vertical Bevel Gear shimming process).

This is for a single shim in one of the following sizes - state which size required when ordering:

Shims are available in the following thickness:

- 0.1mm = 0.004" or 4 thou

- 0.2mm = 0.008" or 8 thou

- 0.3mm = 0,012" or 12 thou

- 0.5mm = 0.021" or 21 thou

It is common practice to measure initially with no shims fitted, then add one or multiple shims to reach the desired final positive backlash, measuring each time shims are added or subtracted
