I've got a 1985 Casita 13' and was going to change out the wheel bearings, I took the dust cover off and instead of a carter key holding the nut in place it has a flat sided washer holding it in place...............My question is how do you get this out, I dug around in there with a pair of needle nose pliers but couldn't get it out...does it take some type special tool ??? I don't want to damage anything so I'll wait to hear from someone who has done this before....
Thanks for any information
Buried under the grease are two nuts with a washer between them. the washer is keyed to a keyway milled into the axle
. The idea is to tighten the outer nut against the washer and inner nut and then bend the edge of the washer against one flat of the outer nut to hold everything in place. To disassemble just bend the tab back down until you can get a socket on the outer nut and take it off. After that the washer and inner nut should come off easily.
When you put everything back together set the bearing play with the inner nut, then put the washer and outer nut back on and torque to recommended value. Of course the final step is to bend the edge of the washer back against a flat of the outer nut.
