Putting the motor back together. How do you guys adjust the valves?

I followed the procedure in the IT manual, seemed to work OK runs fine.

Observe both valves on cylinder #1 while rotating engine. Stop turning just as one closes and the other begins to open. At that point, turn the engine over exactly one more turn and adjust both of those valves. Repeat this procedure for #2 and 3 in the same manner.

Might be wrong but it has always worked for me , I start at the front and turn the motor until the companion valve is about all the way down , then adjust the first rocker arm . Then I go to the next inline rocker and wait until its companion valve is down .

So I adjust #1 when #2 is down , adjust #2 when #1 is down , adjust #3 when #4 is down , adjust #4 when #3 is down , adjust #5 when #6 is down ....... Until I get to the end ,V8 straight 6 , 1 cylinder , whatever .

Some cams have more overlap than others but on your average motor when one valve is close to fully open the other is a long way from moving .

I have tried it buy the book on a V8 to get it tdc and adjust half of the valves then turn the motor180 degrees to get the other half . It was just easier for me to count 1,2,3,4 than to keep from mixing up intake and exhaust especially when you worked on a Ford ( left bank 1-2-3-4 ieieieie ) and the next week a Chevy ( left bank 2-4-6-8 eiieeiie )

He's going to have a hard time adjusting number 4 since a 3000 is a three cylinder tractor and with a firing order of 1-2-3 valve adjustment is different from any other engine

I turn the engine till the intake valve closes then turn the engine another half turn, I adjust both intake and exhaust valves on that cylinder then move to the next cylinder and repeat.

I implied the fourth valve not the fourth cylinder . I know it is a 3 cylinder . If the second valve inline is down you can adjust the first and you work your way down the line no matter how long or short it is .

It is a lot of bumping with the starter but much simpler in the fact you do not need to know what cycle your valves are in or if it is an intake or exhaust . No need to break out a manual when working on a different motor .If you bump the starter too far it does not throw you out of sync . The odds of skipping a valve on a 6 or 8 cylinder are reduced .

Just one of a few ways to adjust valves which may be more confusing to some or simpler to others .
