Repair manual KTM 690 LC4 Art.-No. 3.206.045-E
Mounting the camshaft
– Pull the timing chain out of the chain tunnel, only push the
camshaft into the bearing far enough to be able to place the timing
chain over the rear sprocket.
NOTE: the middle hole
1 of the 3 holes must be in the upper position.
– Push the camshaft into the bearing seats.
NOTE: make sure the rocker arms rest on the valves, otherwise they will
block the camshaft.
NOTE: if the timing chain is correctly mounted, the middle hole will be
aligned directly over the hole
2 for the camshaft retaining bracket
screw.
– Mount the camshaft retaining bracket
3 in the camshaft groove,
apply Loctite 243 to the screw (M6x12) and tighten to 10 Nm.
Mounting the chain tensioner
– Compress the chain tensioner 4 down to the first notch and,
holding it in this position, slide it into the hole in the cylinder head.
NOTE:
– Checking and locking the chain tensioner: see Chapter 5.
– The piston
5 should protrude approx. 3 mm from the chain
tensioner.
– Mount the plug
6 (A/F 19) with a new seal ring and tighten to 25
Nm.
– Hold the plug (A/F 19) while you remove the screw
7 (A/F 17).
