This bearing dolly takes the effort out of changing caravan and trailer bearings. Bearing dollies will last many years. If they mushroom at the head through toomuch hammering, cut the mushroom with a hacksaw.
The dolly is now returned to original condition.
How to install bearing cups
- After the old bearings are removed, and the grease cleaned out, knock in the outer cup until it is flush with the hub surface.
- Grab the bearing dolly and hold it vertical before giving it one smack with a lump hammer. This smack gets the cup started and before the hub journal. You should be able to feel the dolly stabilise on the outer side of the hub journals.
- Hold dolly vertical and smack home with the hammer. Once you hear a sound change, the cup has bedded itself on the bottom shoulder, and the job is finished.
- Lastly, turn the hub over and repeat the procedure on the other side.
Couplemate bearing dollys are a must-have tool for workshops.
