Inspection And Repair Of Oil Pump Drive Shaft Bearings And Bushing

1. INSPECT OIL PUMP DRIVE SHAFT

(a) Using a micrometer, measure the journal diameter of pump drive shaft.

Standard journal diameter:

Front 40.959 - 40.975 mm (1.6126 - 1.6132 in.) Rear 32.959 - 32.975 mm (1.2976 - 1.2982 in.)

(b) Using a cylinder gauge, measure the inside diameter of the pump drive shaft bearing.

Bearing inside diameter:

Front 41.000 - 41.025 mm (1.6142 - 1.6152 in.) Rear 33.000 - 33.025 mm (1.2992 - 1.3002 in.)

(c) Subtract the journal diameter measurement from the bearing inside diameter measurement.

Standard oil clearance: 0.025 - 0.066 mm

(0.0010 - 0.0026 in.) Maximum oil clearance: 0.08 mm (0.0031 in.)

If the clearance is greater than maximum, replace the bearing. If necessary, replace the drive shaft.

2. IF NECESSARY, REPLACE OIL PUMP DRIVE SHAFT BEARINGS

(a) Using SST, replace the No.1 bearing by using No.2 bearing as a guide.

SST 09215 00100 (09215 00120, 09215 00130, 09215-00140, 09215-00160, 09215-00210. 09215 00220)

(b) Using SST, replace the No.2 bearing by using the No. 1 bearing as a guide.

SST 09215-00100 (09215 00120, 09215 00130, 09215 00140. 09215 00210, 09215 00220)

3. INSPECT OIL PUMP DRIVE SHAFT THRUST CLEARANCE

Using a thickness gauge, measure the drive shaft thrust clearance between the thrust plate and collar.

Standard thrust clearance: 0.06 - 0.13 mm

(0.0024 - 0.0051 in.) Maximum thrust clearance: 0.30 mm (0.0118 in.) If clearance is greater than maximum, replace the thrust plate and/or collar.

4. IF NECESSARY. REPLACE THRUST PLATE AND COLLAR

(a) Using SST, remove the thrust plate and collar. SST 09950-20017

(b) Install the thrust plate and collar in the direction as shown.

(c) Using a press, install the thrust plate and collar.

5. IF NECESSARY. REPLACE OIL PUMP GUIDE BUSHING

(a) Drive out the bushing from the outer side of the block.

(b) Drive in the bushing from the inside of the block with a suitable tool.

HINT: The oil hole should be positioned toward the crankshaft side.

(c) Make sure the front mark of bushing should be positioned toward the front of block.
