Information:
Start By:a. remove timing gear cover 1. Remove bolt (1) that holds the relief valve.2. Remove bolts (2) that hold suction tube to the mounting bracket. 3. Use tool (A) to remove the retaining ring that holds idler gear (3). Remove idler gear (3).4. Inspect bushing (4) in idler gear (3). If bushing replacement is necessary, use tooling (B) to remove the bushing.5. Remove bolts (4) that hold oil pump (5) to the front main bearing cap, and remove oil pump (5). Use the reverse procedures of Steps 1 through 5 for installation of the oil pump.Disassemble Oil Pump
Start By:a. remove oil pump 1. Disconnect pump suction tube assembly (2) from oil pump (3).2. Disconnect pump pressure tube (1) from oil pump (3). 3. Remove relief valve (4).
The cap under cotter pin (5) is under spring force. To prevent personal injury, be careful to hold the cap when removing cotter pin (5).
4. Remove cotter pin (5). 5. Remove cap (6), spring (7) and plunger (8) from relief valve (4). The oil pump is serviced only as an assembly. See Specifications for more information on how to check the condition of the pump.Assemble Oil Pump
1. Install plunger (3), spring (2) and cap (1) into relief valve (4). Compress spring (2) with cap (1), and install cotter pin (5). 2. Put a new gasket on relief valve (4), and install tube (6). 3. Connect tube (6) to oil pump (8).4. Put a new gasket on oil pump (8), and install oil pump suction tube (7).End By:a. install oil pump
