It took 17 tons on my left side brake hub. I cut off the clutch hub because I didn't trust the hub threads that that grade 8 studs were screwed into over 25 tons. I pressed them both back on at 10 tons which I think is adequate even though it's less than the Cat specification. All new hubs and plates, springs and retainers; I'm not going back in there....
The trick is to have appropriate tools including adaptors for the various pressing operations - then it's easy. My main tool is a 20 ton hollow ram with a pressure gauge on the hand pump. I had my guy turn down various adaptors so I could press safely and correctly - he only seems to charge 20 dollars per piece which I think is a good deal

Cheers,
Neil

Hi Team,
always ensure any threaded puller bolt/stud is screwed in to the full depth of the threaded holes in these hubs or I have seen short bolts/studs break the side out of the thread boss and then you are up for a hub and a lot of work to remove the old one.
Always ensure that the splined tapers of both the hub and the shaft is totally oil free as I have seen the hubs split due to being even slightly oily--as Neil said the hub does not and should not be pressed on beyond 10 tons--never saw or heard of any at 10 tons dry coming loose in service in our Dealer area, especially on 933 loaders with rippers--some of those units used to get a real beating in our area.
Cheers,
Eddie B.
