Manual Extract: Installation and Adjustment

1. If the port block assembly was removed, install a new port block assembly. See “Port Block Assembly Installation” discussed earlier in this section.
2. Install the thrust washer, 9, and align the timing marks on the idler gear, crankshaft gear, and camshaft gear, as shown in Figure 86, and install the idler gear on the port shaft.
3. Install the rotor, 6.
4. Install the oil pump cover, 5, shim, 4, spring, 3, and collar, 2. Secure the assembly to the shaft with retaining ring, 1
5. Using a dial indicator, 1, Measure the axial movement of the collar, 6. The standard clearance is 0.1 — 0.15mm(0.004 — 0.006 in.) and the maximum allowable is 0.20 mm (0.008 in.).
Install or remove shims, 5, as needed to obtain the standard clearance.

NOTE: Shims are available in 0.1 mm (0.004 in.), 0.15 mm (0.006 in.), 0.2 mm (0.008 in.), and 0.5 mm (0.020 in.) thickness.

IMPORTANT: Insufficient rotor clearance may cause binding and damage to the inner rotor cover or port block. Excessive clearance may allow the oil to bypass around the sides of the rotor resulting in loss of pressure and volume in the lubrication circuit.

6. Install the water pump and cooling fan. See “Water Pump and Thermostat Installation” and “Cooling Fan Installation” discussed later in this section.
7. Install the timing gear cover. See “Timing Gear Cover Installation” discussed earlier in this section.
8. Refill the radiator to its proper coolant level.
9. Replace the engine oil filter and fill the sump with oil.
