    Posted: 30 Sep 2023 at 3:44pm
Happy saturday everyone. My uncle has a wd45 with what I believe is a 4” piston. They were stuck and the pistons were less than pretty when he got them out. The part number on the piston is 226347. I am trying to figure out what he needs for the new one. I found where that part number is a 4 1/8 piston but it does not measure that way. If it is a 4 in piston then How do I figure what compression it is. Lastly if it’s a 4in can I buy a 4.125 cylinder pack and use it instead? Thank you for the help
When your working on something how does it always seem that merphy's law come into affect?

That part number is for the standard 6.45:1 compression gasoline piston. If your sleeves are still good, i have 4 NOS AC pistons with that part number. $150 for a set of four plus shipping. Michael
