PISTON PIN REPLACEMENT R & I
Ensure piston and rod are properly marked. Remove both
circlips from pin bore groove. Use Piston Pin Replacer (VW 207C) to
remove and install the piston pin. If pin is too tight, heat piston to
140øF (60øC). To install, reverse removal procedure. Ensure rod is
properly positioned with piston. See Fig. 15.
CRANKSHAFT R & I
1) Using flywheel Holder (10-201), remove flywheel bolts.
Remove flywheel. Remove front and rear oil seals and covers. Remove
connecting rod bearing caps.
2) Measure crankshaft end play. See CRANKSHAFT END PLAY CHECK
in this article. Remove main bearing cap bolts. Remove main bearing
caps. Remove crankshaft. To install, reverse removal procedure.
MAIN BEARING INSTALLATION
Main bearing caps are marked with matching journal and must
be installed to original position. See Fig. 16. Thrust bearing is
located at No. 3 main bearing cap. Use Plastigage method to check
clearance. Machine or replace as necessary. See ENGINE SPECIFICATIONS
at end of this article. Tighten evenly to specifications in several
steps.
CONNECTING ROD BEARING INSTALLATION
Ensure rod caps are marked to ensure installation to original
position and location. Use Plastigage to measure bearing clearances.
Measure connecting rod side play. Replace or machine as necessary. See
ENGINE SPECIFICATIONS at end of this article. Tighten evenly to
specifications in several steps.
CRANKSHAFT END PLAY CHECK
Insert feeler gauge between No. 3 main bearing and crankshaft
thrust face to measure end play. See Fig. 16. Replace thrust bearing
as necessary. See ENGINE SPECIFICATIONS at end of this article.
Original thrust bearing uses plain shell with 4 separate washers and
replacements have attached collar.
REAR MAIN BEARING OIL SEAL R & I
Remove flywheel/flex plate and discard retaining bolts. Oil
seal may removed without removing retaining flange by prying seal out.
Remove retaining flange if gasket is leaking. See Fig. 16. If
installing without removing retaining flange, use Centering Tool
(2003/2A) to center seal and Installer (2003/1) to install seal.

connected, timing mark on flywheel should appear at pointer in hole.
NOTE: Before checking engine timing, raise engine speed above 2100
RPM at least 4 times. This must be done each time ignition
is turned off and restarted to clear ECU memory and by-pass
hot-start, fast-idle function.
3) If an adjustment is needed, turn ignition off and loosen
distributor hold-down bolt (2.0L has 2 hold-down bolts) just enough to
move distributor by hand. Start engine and allow to idle. Turn
distributor until timing mark is aligned with pointer in bellhousing.
4) Stop engine and tighten hold down bolt to 18 ft. lbs. (24
N.m). On 2.0L tighten hold-down bolts to 87 INCH lbs. (10 N.m). Check
and readjust if necessary and install plastic plug in inspection hole.
VANAGON
1) Engine oil temperature must be 176ø F (80ø C). Connect
timing light and tachometer. Start engine and allow to idle. Check
ignition timing at 800-1000 RPM.
NOTE: Before checking engine timing, raise engine speed above 2100
RPM at least 4 times. This must be done each time ignition
is turned off and restarted to clear ECU memory and by-pass
hot-start, fast-idle function.
2) If an adjustment is needed, turn ignition off and loosen
distributor hold-down bolt just enough to move distributor by hand.
Remove connectors from idle stabilizer by squeezing connectors then
pulling apart. Plug idle stabilizer connectors together.
3) Start and allow engine to idle. Turn distributor until
notch on V-belt pulley matches separation in case. Set timing and RPM.
Reconnect electrical connectors to idle stabilizer. Tighten
distributor clamp bolt.
