Question about track chain condition for D2 J series

Can I assume that since the links in the track chains of the 22, R2 6J, and the D2 5J are that same part numbers that the height of the link—3.00 inches new and 2.75 inches worn out, I believe—and the measured distance across several links—I forget the number—would be the same in determining the condition of the chains?I have a 22 that I might part out and would like to use the tracks for one of my running 22s. The links measure 2.85 inches high but I haven’t been able to measure the distance across the several links yet.What are the correct heights and distances across the links?ThanksPete

Hi Pete, the pitch is 6.125

Thanks, Neil.
I want to use the the tracks on another Cat but don’t want to go through the effort of changing them if they are worn out. I read somewhere that you stretch the chain by backing uphill and then take a measurement across a certain number of links. Do you have those numbers?
Pete

Pitch 6.12" C/L
Link Height: 3" new  , 2.69" wore out
1.16" width of link where rollers contact.
Measuring over 4 links: 24.48" New ,  25.07" Wore out

Thanks, side-seat. That helps a lot.
Pete
