Injection Pump Timing
- Remove distributor head bolt on injection pump. Install special alignment tool (Toyota Part No. 09275-54010) and dial indicator to distributor head plug.
- Set No. 1 or No. 4 cylinder to 45° BTDC on compression stroke. Set dial indicator at zero. Check to see that indicator stays at zero when crankshaft pulley is rocked slightly to left and right.
- Turn pulley until No. 1 or No. 4 cylinder is at TDC. Dial indicator should read 0.0394" (1.00 mm). If not, loosen injection pump bolts and all fuel connections.
Install special tool and dial indicator as shown.
- Tilt pump body slightly and recheck injection pump stroke. When correct, tighten bolts and fuel lines, then remove tools and install distributor head bolt and washer.
