No aftermarket available yet, not even from China.

Our latest-generation SALT chains with PPR are consistently giving us over 10k hours to scrap. We don't do pin & bush turns as we've found it's not worth it, so we run them to 125% wear first time round and call that it. The number of dry joints we've had you could count on less than one hand. Most if not all were on our first tractors and there was a Cat Service Program covering it. Lately I can't recall a single one.

Our next move it to try the new single tooth master links.

What is the ppr stand for?

Are the Pin Bores Staked to the pins in these Nige? Looks a lot like the Primer Pockets on my .50.

PPR means Positive Pin Retention. It's a ring on each end of the track pin that locks it in place.

I suspect someone other than Cat makes System One because Komatsu Plus One is that same type of track.

I see I read up on it never dawned on me that the end play was the killer

Komatsu make theirs to their spec and I’d be surprised if there’s an aftermarket fix there either. I spent time last year trying to source a-m for a Cat and no go anywhere in the world at that time. I’d be very happy to be wrong, though.

I didn't say that it was available after market. I suspect someone holds a patent and sells on exclusive agreement. The track chains are of the same design but probably has differences in pitch and chain gauge.
