Setting the valves? (Super 55)

[Ol 54']

Now that I have installed a new muffler on my 4 cylinder gas tractor, boy can I hear some noisy valves or lifters a clattering. Need some info on what the settings are and the easiest way to set each cylinder through the rotation cycle. Thanks there farmers.

Standard method is to count to nine for a four cylinder engine. One valve open, the other closed. Simple.

Well not quite sure what you mean by that, I have set a lot of valves on some chevys and fords but not quite sure about the 9 count? :?:

This is a gas tractor? Valve clearance is 10 & 16. Firing order is 1 - 2 - 4 - 3. Do number one and a half turn of the crank later do # 2, then another 1/2 turn do # 4 and a half turn later do #3. If nothing else find #1 TDC by removing the distributor cap and turn the engine in the direction of rotation till the rotor lines up with #1 spark plug terminal. Questions? Have a phone number.

Now that makes sense to me Thank you J. Schwiebert for the info.

Looks as if I found my old name here on the forum. Hopefully I am not interrupting anything here on the sight. I just don't know if I can combine bothe names into one. Probably need to contact the moderator. Thank you.

I am looking for the marks on the flywheel for # 1 cyl. So I can start my valve settings. I have the rotor on the distributor pointing towards #1 while rotating the engine back and forth. Problem being I can't seem to see any marks on the flywheel through that witness hole to verify it is in the #1 cyl. Is there another way of performing this, or how would you time this here Super 55 if you had too?

You don't need timing marks to set the valves. You say the rotor is pointing at #1. If #1 is ready to fire (for setting the valve clearance) both valves will have lash (free to move). And if you watch the rocker on #4, as you turn the engine back and forth a bit, you will see the valves on #4 will be "on the rock", no lash, both rockers will be tight (exhaust valve closing and intake vale opening). The info J. Schwiebert gave you, above, still holds true.

Well probably my fault but along with setting the valves my plan was to was to also time it. I noticed there is a notch ground out in the witness hole on the aft r/h side of the block. On the flywheel there are some numbers stamped and a kind of a 0 at the fwd. end, along with all that the rotor on the distributor is pointing towards #1 with the valves loose. By the way I haven't heard from J. Schwiebert in a while..Thank you..

Sounds like you found the timing marks on the flywheel and the indicator. 0 would be TDC. You likely need to do some cleaning to see the marks. I've had to use some, brake cleaner, strips of emery and a stick before to clean flywheels to see the marks. You likely need to clean to or beyond the 30 degrees advanced so you can check distributor advance with your timing light.

For setting valve lash the fool proof way is to turn engine in direction of normal rotation,when the exhaust valve begins to open the intake for that particular cylinder will be on the base lobe of the cam. After setting intake continue to rotate until the intake valve totaly opens and gets close to being closed again then your exhaust will be on the base lobe of cam and ready to set for that same cylinder. This is not just my way. Many moons ago when I was a teenage wanabe gear head I bought a crane cam and it came with those instructions on setting valve lash. Your dealing with both valves on one cylinder at a time and its pretty hard to get mixed up as to were you are at.
