(2) Collar
(4) Shim
(12) Feeler gauge
Use feeler gauge (12) to measure the distance between C-clip (1) and collar (2).
When the components of the engine oil pump are installed on the front housing, measurement (B) between C-clip (1) and collar (2) must be between 0.10 to 0.15 mm (0.004 to 0.006 inch)for new components. Dimension B must be not more than 0.20 mm (0.008 inch) for used parts. The distance between the faces is adjusted with shims (4). The thicknesses of the shims are given in Specifications, "Engine Oil Pump".

Install the components of the engine oil pump and the front housing on the cylinder block. Make sure that the two dowels align with the bushing, the outer rotor, and the holes in the idler gear. Align the timing mark (15) on idler gear (10) with the timing mark on crankshaft gear (16) when you install the idler gear on the oil pump shaft. Also, align the other timing mark (15) on idler gear (10) with the timing mark on the camshaft gear (13). The hole (14) in oil pump cover (5) should align with the locating pin in the front housing.Note: When the front housing is not installed on the engine, do not rotate the crankshaft.
