VALVE CLEARANCES.

1. rotate crankshaft by means of crankshaft pully bolt in a clock wise direction untill number 8 valve (counting from front of engine) is fully open.

2.using feeler gauges and a screw driver, adjust clearence of number one valve.
valve clearences - all valves = 0.20mm

3.tighten tappet adjusting screw locknut when clearance is correct.

In these engines the valves you adjust add up to NINE with the valves on full drop.

Valve 8 fully open adjust valve 1 ------ so = 9
7 down adj 2 so = 9

and so on and so on

Finally- Thanks Trewey.. it's nice to find help. Not many manuals in the Masai mara.

Right so now the valve collars have gone.. any feedback on changing these would be much appreciated.. special tips?

discomania · Jun 4, 2013

Valve collars? I trust you mean caps and not collet as the valve would have fallen into the engine if the collet's had disappeared!

First thing to do is get GOOD caps. Even the Gen LR ones are poor now. If you can make a mark on the cap with a hacksaw then it's rubbish.

I get mine from Turner Engineering.

Wind the adjuster a bit so you can slip them in, bit of molyslip under the cap and carefully pop it onto the top of the valve. Set the clearance then put a little moly slip in-between the cap and the rocker. Rocol MT-LM would do too.
