Essential when rebuilding your engine to ensure that the upper vertical bevel gear has the correct backlash and position in relation to the camshaft bevel gear, these upper bevel shims fit between the cambox shell casting and the upper bevel housing -

Fitted in conjunction with the camshaft bevel gear shim, the ideal positioning is acheved when the gears are in line and there is a just perceptible gap (backlash) between teeth.

This is for a complete set of 5 shims in the following sizes :

0.5mm/0.3mm/0.2mm/0.1mm/0.05mmNote - shim steel is now supplied in metric thicknesses, but these are offered in the nearest equivelant to the old Imperial sizes that were commonly used - i.e.

0.5mm = 0.021" or 21 thou (for some reason the actual thickness is 0.53mm which = 21 thou) 

- 0.3mm = 0.012" or 12 thou

- 0.2mm = 0.008" or 8 thou

- 0.1mm = 0.004" or 4 thou

- 0.05mm = 0.002" or 2 thou

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

Packed in Duck Oil to protect from rusting, with slight cost saving over buying individually
