Important: After measuring clutch pack travel,
determine if the measurement is within the
specification. If the measurement is not within the
specification, measure the thickness of the existing
snap ring, and then choose a thicker or thinner snap
ring that will bring the measurement within
specification.

Rotor and slide must be chosen from the same size
classification as the oil pump body.
Allowable rotor and slide to oil pump body end play
The oil pump assembly has "selective" rotor and slide
components. These components are chosen based on pump
body dimensions. Oil pump rotor and slide components are
available in three size classifications (1, 2, 3) with the following
tolerances.
Slide to Pump Body Face
0.020-0.051 mm (0.0008-0.0020 in.)
Rotor to Pump Body Face
0.020-0.038mm (0.0008-0.0015 in.)
