Fuel Injection Pump: Installation
- Install pump, aligning marks on pump and mounting plate. On Volkswagen models, install injection pump sprocket. Tighten pump mounting bolts and fuel pipes to 18 ft. lbs. (24 N.m).
- On Audi models, align rear support so it contacts cylinder block and injection pump without tension. Tighten support mounting bolts. Install injection pump sprocket and turn it until marks on sprocket and mounting plate are in line. See Fig 1.
- On all models, lock pump driven sprocket with special setting pin (2064) and tighten driven sprocket retaining nut to 33 ft. lbs. (45 N.m). See Fig 1. Install drive belt and injection pump drive sprocket. Tighten drive sprocket retaining bolt so that sprocket can still be turned by hand. Check drive belt tension with VW 210 scale. Value should register 12-13 on scale.
- If not, adjust drive belt tension by loosening bolts and moving mounting plate with pump. Check if TDC mark on flywheel is still aligned with reference mark. Tighten injection pump drive sprocket bolt, using special pulley locking tool (3036), to 72 ft. lbs (98 N.m). Remove special setting pin and pulley locking tool. Check injection pump/valve timing and injection timing.
- Reinstall fuel pipes, drive belt cover, and vacuum pump pulley and drive belt. Reattach accelerator cable and wire to fuel shut-off solenoid. On Turbo Diesel models, reinstall boost pressure intake line to boost pressure enrichment device on injection pump.
