- Turn crankshaft at central bolt of toothed belt gear in direction of
engine rotation to cyl. 1 TDC. Timing marks -A- and -B- must be
aligned.

WARNING!
DO NOT turn crankshaft while checking for TDC mark. Personal
injury may result. - Check position of camshafts. Large holes (arrow) of securing plates on
camshaft sprockets must face toward inside and align.
If not, turn crankshaft one revolution further.
- Remove sealing plug from left-side of cylinder block.
- Top Dead Center (TDC) mark on crankshaft must be visible or be felt

CAUTION!
Before removing ribbed belt, note direction of rotation with chalk or
felt-tip marker. Reversing the direction of rotation of a used belt can
destroy the belt. When installing the ribbed belt, make sure it is
seated correctly on the pulley.
Notes: - Install 3242 crankshaft holder into sealing plug opening.
- Remove tensioner for ribbed belt.
- Remove center and right toothed belt guards.
The toothed belt tensioner is oil dampened. Compress it by slowly
applying constant pressure. Use spring clamp from 2024A.

- Using 8 mm hex wrench, turn toothed belt tensioning roller -1- counter-
clockwise, opposite direction shown (arrow), until tensioning lever -2-
compresses tensioner -3- so that spring clamp (2 mm dia.) can be
inserted into bore and lifter.

Note:
The camshaft sprockets should be loose enough on the cone to be
turned, but not so loose as to be tipped. - Remove both camshaft sprockets using T40001 special tool.
- Reinstall both camshaft sprockets together with locking plates and
hand-tighten.

- Install toothed belt on all sprockets as shown in illustration.
- Install 3391 camshaft locator bar.

1) Always replace the center bolt. 2) Two turns of 90 are permissible. - Using 8 mm hex wrench, turn toothed belt tensioner roller -1- counter-
clockwise, opposite direction shown (arrow) until tensioning lever -2-
compresses tensioner -3- so that spring clamp can be removed and
then remove clamp.
- Before starting engine, pre-load timing tensioning roller as follows:
- Using a torque wrench with 8 mm hex bit, apply tension to toothed
belt clockwise in direction shown (arrow) until a torque of 15 Nm is
attained. This ensures tensioner has expanded completely and is
properly engaging toothed belt. Component
