continental flat head

Trying to help a friend. 6 cylinder flat head model F226. I need to adjust the valves. I have the specs, but not the procedure. Do you adjust it running?

No. Adjust them cold. If you try it running, you will get an oil bath.

Do you know the procedure, which piston to set at top and which valves to adjust in each step? I am familiar with the way to do 4 cyl IH, but this is new to me.

John,

Do them in firing order, easiest to start

with # 1 and timing mark at the pointer, mark

damper in thirds. Every time you adjust a valve

rotate engine 1/3 turn.

DO NOT EVER adjust while running, ruins the

feeler gage and does not give you a true setting.

I don't know how a person could adjust the valves with the engine running cause the intake and exhaust manifold has to be removed to get the side cover off to get at the valves!! Here is how, remove manifold and cover and plugs, check the firing order on top of the head, start with # 1 cyl. Turn engine with crank or fan and watch the valves, exhaust opens then intake opens and when intake closes keep turning until that piston is at top, look in plug hole with a light, with piston at top you are at compression, set both valves on that cylinder and go on the the next in the firing order. I set the F226 intake at 14 and exhaust at 18, that's cold, have fun!

Yep, there's LOTS of oil flying about the tappet area of a flathead!

Thanks everyone, I was wondering about that but I found 2 different scans of original service manuals on line that stated in the regular maintenance section that every 500 hours the valves should be adjusted at operating temperatures and idle speed. It is supposedly a manual for my engine.

I had to look in the book and found that statement also and the same picture as you posted, but notice in the picture the manifold is removed so kind of hard to do. It's a SOB kind of a job to set them, you need 3 wrenches and a feeler gauge, don't know how a person could ever set them with the engine running. Just finishing one up today and will reinstall it back in the tractor tomorrow.

Thanks Mike, and everyone else who replied. Wouldn't be the first time I have seen instructions in a service manual written by someone who has never done the job. I noticed a while back that one of the Farmall cub manuals has the oil slinger for the fan illustrated reversed. Fan bearing would not last long if installed that way.
