valve adjustment

Recommended Posts

Howdy I have a c200 gas engine in a 574 that I rebuilt this past spring getting ready to change the oil , adjust valves and retorque head for 1st time since. I assume I should do all that with engine warm is that right? thanks

Yes Sir, It is the way we always did it when engine is at road temperature.

Thanks I figured so but I know when the engine was assembled it would have been cold

The IH manual # ISS 1039-1 suggests anything above freezing is warm enough and suggests a "HOT" engine is uncomfortable to work on and might cause mistakes. I got a laugh out of that item but does seem to be true that the factory wouldn't take time to get it hot.

X2. We set the valves at room temperature on my pulling motor and have no issues.

do any of you know where to get a good crank at a good price? new or used?

 

Crank for what? 

 

Yes, set valves at "room temp".  When the book says "warm" it just means not freezing.  If everything is "hot" like running temp, you will burn your hands, and the setting won't be correct.  

Personally, I wouldn't retorque the head.  Let it be if it was that long ago you overhauled it.  If you are going to retorque, it should have been within the first couple hours of running the motor.  30 minutes run time after overhaul if you do it at all.  Only heads I retorque are air cooled unless the manual specifically suggests it.  Pretty sure it doesn't on that motor.  Honestly, even if it does I still wouldn't.

Retorque the head and then reset the valves.

I always done it hot.

Hot, meaning it was just running and generally not on the dyno, HOT!

Just ran into a 706 gas with a slight, but noticeable miss.

One valve was just a few thousandths to tight.

Retorque and reset valves was always to be done after a few hours of operation.

It does take time, is a pain to do, and most do not put out the effort.

It is worth it though.
