Hi,

I have these pistons in my 1943 Farmall H.

Pistons and liners look great (std. bore) and I like to reuse these pistons. Is there any source for new piston rings? I don't want put on the old ones in again.

I measured these rings and it seems as if the standard IH rings are different.

Can anyone help me?

My book only lists 4 rings for that piston. 3-7/16 bore with three 3/32 rings and 1/4 oil ring. top and oil ring was chrome. Don't recall or have wrote down what size IH 3-7/16 ring sizes for a H are.
 
Thank you for the Hastings link. It seems as if there something available for my pistons. I just saw that my pistons are NOT standard bore... I have a M&W over bore kit with 3 7/16 bore in it.

Sorry for my mistake.

Hastings shows items #2C7681 and #2C5669 which may fit. Which one would be the right one?

Thnak you.

Hendrik
 
Choose the part number that uses chrome plated compression rings. Make sure to check the end gap of the compression rings when installing them. End gap is
about .1mm for every 25mm of bore diameter. Jim
 
I have a M&W book & a 2016 Hasting book. SP70 M&W sleeve & piston set with AP 70 piston uses a 2C5669 Hasting ring set. 3.7/16 bore. 4- 3/32 compression rings top ring chrome 4- 1/4 chrome oil ring. Hasting PH. # is 269-945-2491 You might ask for engineering & they will help you make the purchase. Earl
