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 camshaft bevel shims fit between the camshaft 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.
This is for a complete set of 5 shims in the following sizes : 0.030”/0.018”/ 0.012"/0.006"/0.003” (metric equivalent: 0.5mm/0.3mm/0.2mm/0.1mm/0.05mm) + the A11/788 camshaft back distance piece - with a cost saving over buying them separately.
Note: The A11/788 back distance piece can be bought seperately - Item 0329, as can these shims in the individual sizes.
Update Feb 2020: All sizes now back in stock again
