3. Tensioner Locking Pin (H)
3-1 To remove the timing chain, the chain tensioner must be
'lockedback' and removed. Release (1) and simultaneously
push back (2) and insert (H) through the hole (3) to lock back
tensioner.
3-2 Remove the tensioner, rail and chain guides. Mark the camshaft sprockets as "inlet" and
"exhaust" before removing them, along with the injection pump sprocket and timing chain.
IMPORTANT: (G) are designed to allow removal of the sprockets without removing the timing pins.
DO NOT remove the pins from their timing holes when sprockets have been removed.
3-3 When re-assembling the sprockets, chain and front end, ensure that the 3 copper colored links on
the timing chain align with the timing marks on all three sprockets, and the chain is taut on the non-
tensioned side. Loosely fit the camshaft and injection pump sprocket bolts (finger tight only). Re-fit the
chain guides and tensioner, then withdraw (H) from the tensioner to activate it. Tighten all sprocket
bolts to the specified torque and then remove the locking pins.
4. Timing Check
To ensure engine timing is correct, tum the engine over, by hand, two revolutions, returning to 50°
BTDC and insert the correct flywheel locking pin.
Check that the 3x (G) can be inserted into the timing holes of the camshafts and injection pump timing
holes. If the 3x (G) cannot be fitted then remove the chain and repeat the procedure, engine timing
adjustment. IMPORTANT: Do not slacken the sprocket bolts unless the locking pins are fitted. If only
the injection pump locking pin will not enter - slacken the 4 sprocket bolts, tum pump shaft nut slightly
until the pin enters, then tighten sprocket bolts.
5. Front Cover Installation
Note: If the front cover is damaged or distorted from removal, then a new cover should be used.
When installing the engine front cover it must be correctly positioned relative to the crankshaft using
(A). This ensures that the crankshaft seal located in the engine front cover is correctly aligned and will
not wear prematurely. Ensure that the engine and front cover mating surfaces are clean and that any
old sealant has been removed.
