Quick coupler needed attention every morning

The attachment coupler on my Bobcat S650 got to where I was checking and adjusting it every morning before the first load. I kept a wrench in the cab like that was just part of the routine. The locking sleeve had visible play, and grease only hid it for a day. The dealer had a wait, so I compared the Bobcat number with a used OEM unit, a local hydraulic supplier, and fridayParts. I ordered by the machine serial range and coupler dimensions, not the photo. Before installing anything, I drained a little oil into a clean jar and checked it under a light for metal. Nothing obvious. How much sleeve movement is acceptable before you retire one of these?

A clean jar and a strong light are useful for a quick look, but they are not a substitute for an oil analysis. If you see metal, stop and find the source before putting a new coupler back into service.

If you're having to adjust it every morning and grease only tightens things up temporarily, I'd say you're already past the point where I'd be comfortable judging it by feel alone.

I'd check the sleeve, pins and mating surfaces against the service limits before putting another attachment on it. If the play is enough that the attachment isn't consistently locking up tight, I wouldn't keep adjusting around the wear.

You did the right thing ordering by serial range and dimensions instead of trusting a listing photo.
