Setting valves
« on: September 26, 2016, 01:08:44 PM »
Being retired sometimes means I screw-around with my toys looking for stuff to do...and do stuff when its really not necessary. While I am waiting for some stuff to come in and have the interior out I decided it was a good time to check the valves on the front cylinder. Now at about 200 miles I set all the valves once mostly so I knew where they were. And now it have about 700 on it I wanted to re-check them cause...well something to do...and I don't plan on opening it back up for a while. I always set my valves mid-range unless I have a reason to do it differently and that's what I did last time. This time I found that over the last 500 miles the intake's lash depleted to the minimum clearance, which usually means seat wear thanks to the stock air filters, and the exhaust's lash had increased to the maximum clearance, which usually means cam, rocker or tappet wear and that could be just breaking in. After setting them back to mid-range the engine ran quieter and smoother. I still need to do the rear but will need to pull the storage box to open it up. I'll check them again in 5 or 6 hundred miles but I thought it interesting they had changed that much in such a short time. I know many people out there have never checked theirs but it might be a good idea to every once in a while.

I think after the valves get beat in and the have heated and cooled many times the steel stretches and stress relieves. You may not get too much change for awhile. I would do me more, but it's a major ordeal to do.

I'm hoping they settle down.

How big of a pain is it to re-check the valve clearance. I know having a 600 I have to take off the back of the body. No problem. Do I need any special tools? Any videos out there? The service manual is kind of vague.

No it's actually quite simple on these after exposing the head. Just remove the valve cover and spark plug(s), set it on the TDC of the compression (not exhaust) stroke. Just need a set of feeler gauges, 10mm end wrench and something to hold the adjuster like a needle noise vise grip. Engine has to be dead cold...ie not run in over 6 hours or more. There are lots of video on setting valves..probably not too many on CFM engines though. But really its all basically the same.

After taking a million push pins and bolts out the valves themselves aren't bad. 10mm box wrench and a small screwdriver or a square deck screw if not a slot on the adjuster.

Well,

I will take a look at some videos and since I have a 4 day weekend coming up. I might just attempt to set the valves. It has almost 900 miles on it and I don't know if they have ever been adjusted.
Sounds like I may need a case of Guinness for the weekend.....LOL

LOl..next time I will. Or maybe I'll do one when I do my rear cylinder. I have the cab-side all back together now.

Too much driving for five minutes work...lol. It's a shame they didn't just point that one cylinder toward the back instead of the front. Would have made service work a lot easier.

No doubt.... Having the cylinder facing back would have been great.

Found this. Because the CFM800 is a copy of the Rotex 800, this gives a good general idea. He does not put enough drag on the feeler gauge but its a good general video. Ours don't turn over as easy.
