(d) From the exhaust cam remove the bolt that is at the 10 o’clock position and from the
intake cam remove the bolt from the 2 o’clock position.
8. Installing timing belt
(a) Install the timing belt on the intake cam. Make sure that the gear is at the proper
position with the pin straight up and the alignment marks are horizontal.
(b) Insert a tie wrap (supplied with kit) into the
open bolt hole and tie wrap the belt to the
gear.
(c) The exhaust cam may be off from proper time
due to the valve spring acting on the cam
lobes. Use a wrench to rotate the gear into
proper time as you install the timing belt.
Insert a tie wrap into the open bolt hole and
tie wrap the belt to the gear to prevent the belt
from slipping off the gear during installation.
(d) Timing belt tensioner
i) Try to complete the installation of the
timing belt without loosening the timing
belt tensioner pulley. However, if difficulty
is encountered and loosening the
tensioner pulley eases the installation of
the timing belt on to the pulley system
then the tension on the timing belt will
have to be reset.
ii) From beneath, remove the automatic belt
tensioner.
iii) On a vise, compress the tensioner until
the hole in the shaft aligns with the hole in
the tensioner body.
(1) This procedure should be done over a
15-minute period to allow the tensioner
to bleed down. If you compress the
tensioner down too fast you may
damage it internally (please see the
factory service manual).
iv) Once the tensioner has been compressed
and the holes are aligned, insert a

inch pin or nail into the holes to lock the
tensioner in place.
(e) Complete installing the belt on to the lower pulleys.
i) Ensure that all the timing marks are in their proper position after the belt is installed.
Any deviation from these procedures can lead to serious engine damage.
(f) Install the timing belt tensioner. If you loosened the eccentric idler pulley for the
tensioner you will have to reset that pulley before you complete the assembly.
9. Resetting the tension pulley
(a) The following procedures are to be completed if the tensioner pulley was loosened
during the removal of the timing belt.
