Thanks Richard now I know the torque foot lbs. for the pistons too. Hope you have a vedeo for installing the valves, need to know what filler guage size is used for CJ2A, M38 AND CJ3B, M38A1 I'll be working on this soon but still trying to find the best overhaul catalog that best fits all. Thanks again. This vedeo helps.
The T slot is the weakest point of the piston as far as compression leaking down past the piston and into the crankcase. The ring gaps are staggered and away from the T slot so as to not enable compression to have a straight path to the T slot and past the piston.
Please be careful that you have the correct ring application for the pistons/engine you are working on. There are several different ring manufacturers that have different installation instructions. Regardless, if you know you have the correct rings for that engine, follow the instructions that came with it. Also, regardless if the bevel is top or bottom of the ring, if it is marked TOP or has a stamped dot...then those are the top of the ring.
This is a well detailed video on ring installation for these old motors. I finally found which groove to put the ring with the dot. Thank you RIchard.
The Mechanics Manual from Willys states that the upper ring should have the bevel facing upward. Now I'm confused. Help please.
Thanks a lot for this video. Very usefull. I`m repairing the engine in a m606 (cj3b). I hope enjoy a ride soon. Cheers from Argentine
You're very welcome. Glad it was helpful to you.

Just curious, What’s the reasoning behind keeping the spacer spring gap away from the T slot?
Thanks!

How do I determine the torque spec that I should use if it’s 35 to 45foot pounds Should I go in the middle and stay at 40?
In between at 40 is fine if you're rod bolts are 3/8". If they are 7/16" ,then 50-55 psi. Head BOLTS are 60-70. Head STUDS are 65-75
Thanks for the info
@@normanfields6371 you're welcome
My top two piston rings had the bevel on the top with markings on all rings saying "top" is that just because my parts are different
