Cm2250 overhead set

[Waterloo]

I don't know who Simon is, or why you would need to use a dial indicator... I would purchase an inch pound torque wrench, will be more accurate than using a foot pound at those numbers. But, if it is all you have, just make sure you release all of the tension on it and then set before use.

Rawze has a good video on doing the overhead, even though it is on a CM-871, the same procedure applies, as the exhaust side is identical to yours.

Tekton makes a decent torque wrench for the money, that is what I use...

Many of the Farm and Fleet or Tractor Supply stores sell these, so you may be able to purchase locally. Prices are normally on par with internet pricing, around $40.
