Help adjusting valves on an LX665

[acarlo]

I am trying to adjust valves on this machine and cannot find a mark on the pulley. I have the pan off, side panels off, lots of light and even a magnifying glass. I cleaned the pulley and ran chalk around it no mark. I was gouing to run a wire down the glow plug or injector hole but there seems to be a shroud in the head that doesn't allow me to do it. Has anyone had an issue like this? I need to get it to TDC on the compression stroke. Thanks for your help. Art

Did you look on the front face of the pulley?

I did from a bit of an angle. I may have to remove the radiator to get a better look.

Can't find a mark but there are the letters T and A stamped on the inside ring of the pulley.

The service manual shows it on the front but I think it is a notch on the edge of the pulley next to the timing cover. To get you close to TDC turn the motor over until both rocker arms on number 1 valves are loose, #2 intake rocker is loose, and #3 exhaust rocker is loose. Then look closely at the pulley in front of the timing cover timing marks.

Mike, thanks a million. It was hidden by the belt and is on the pulley next to the cover.

Mike, I was wondering your opinion/method for setting valve lash. When I did the head on my shibuara 844, it seemed like the oil on the studs, rockers and pushrods all played a part in the final setting. If you check it to many times you end up wiping the oil away. Just not sure if your better off a little tight or a little loose?

I usually do not get involved in engine work. When I have been present when a valve adjustment was being done the parts were generally somewhat dry because of a repair. I do not think a little varience in the clearence will make much difference.

I'd have to agree. That's why they generally give you values like .007" - .009", i generally work on .008 in those figures. A small amount out should still be ok, i don't know if i'm right or not, but i'd always rather go a little more than less though. I always figured that would give a little more compression before the valve opened rather than less if the clearance was smaller.
