Front rotor replacement, not fitting on spindle

[jeremypbeasley]

I’ve got a 1985 2WD Vanagon (manufactured 12/84). I’m rebuilding my front end and stuck on a rotor figment issue.

All new rotors and bearings. Rotors and bearings match the measurements of the ones I had before that were operating well but due for replacement. I’ve pressed the bearings and seals into both rotors without issue. When I place the rotor on the spindle though, I don’t have enough of the shaft coming out of the front (through the putter bearing) to put my nut on.

This makes me think it’s not seated on the spindle correctly. When I take either my new or old inner bearing and place it on my spindle, it stops at the end of the tapered portion of the spindle. Is that correct? Or should it go all the way to the end?

Rotors are ATE brand from the brake kit here: https://vancafe.com/1980-85-2wd-front-brake-kit/

When I take the rotor off the spindle, it leaves behind the seal and inner bearing stuck on the spindle. If I place the rotor back on the spindle (with the seal and inner bearing in hand), it seems to fit fine, leaving plenty of thread for my nut.

Any help would be much appreciated!

your inner bearing should go all the way on.

Welp. This one’s on me.

For future reference: It took several tries to seat the rotor on the spindle. I had to reinsert the inner bearing and seal each time. The spindle OD and inner bearing ID are super tight so it’s a tricky fit.

There is a very specific way that bearing is seated onto the spindle.
You tap the inner race with a punch, going around and around, evenly.
Or if you have a pipe that doesn't touch the bearing cage.

You don't want to do anthing that presses it on top the spindle with any force upon the rollers.

Recommend you check your method with the forum here first - or the bearing can be damaged.

The inner bearing is an easy slip fit on the spindle. No hammers!

Take a bastard file and run it around the spindle to see if there are any high spots where the inner bearing race is supposed to fit.

just replaced mine also on my type 3, it is supposed to slide on completely without any problems or hammering, what make/type are the bearings? Did the other side go on without any problems?
