Lift Chain stretching

We have run into this situation a lot lately:
The lift chain is stretched and the chain anchors have no adjustment left. We buy a new chain and cut it to the same # of links as the original chain, install it and again the chain anchors are bottomed out with no adjustment left. The only way to leave some adjustment in the anchors is to shorten the chain. The problem with doing that is now the mast and cylinder sequencing may be incorrect and the chain could break.
Obviously, we have to assume that the trucks have the original chains in them and that there was plenty of adjustment in the anchors when the truck was new.
Can someone please explain.

if you shorten the chain don't just worrry about the chain breaking, keep an eye on the carriage stops. They should not touch when the carriage is all the way up. It's fun when the carriage falls out the top of the mast in front a major building box store.

When in doubt replace the operator
are the bearings collapsed/worn on the chain roller. What size truck are we talking about?

Not very.
In cases where the tires were worn significantly we jacked up the truck to make up for the difference in tire wear and still the chains were loose.
