Eriba Puck - From Bearings to Drums to Electrical to ??

I did not see any forum for "Other VW related Technical" so since I have seen Eriba Pucks owned by Bus owners and other posts here regarding the Eriba Puck, I figured I would start it here.

I need to replace the wheel bearing seals on my late 60s early 70s Eriba Puck as grease is coming out the inner seal area and getting all over the wheel.

I removed the tire, popped over the outer metal cap, removed the retaining pin, the washer, and that is where I ended. I would have thougt, like a VW drum, the whole deal that holds the bearings would now just pull off. I pulled, but no luck.

What do I need to pull things like this off? Is this item considered a hub or a drum? I called it a drum but maybe that is not the proper word for it. So, would I need a drum puller?

Any guidance would be great.

I want to get all the seals replaced so I can start using this Puck as I am tired of it just sitting on the garage. Mad

Thanks

Looks like you need to use a puller to push against the axle, and pull the hub off.

I believe most of the Puck and other trailer stuff is in Accessories but I didn't see much technical information there.

I can't help TJ but I love to know the outcome as I should be doing that to my '67 puck! Please keep me in the loop and good luck!

By the look of the end of the axle, it is indented for recieving a puller. I would say find a puller that would attach to the lug studs and center in the end of the axle for the leverage point.

If you use a puller that attaches to the lugs, make sure all four are attached. Otherwise you can pull out the studs. Prefer a puller that hooks onto the OD of the hub instead....

That's a good point, perhaps pulling from the backside of the hub would be a preferred way.

Hey tj,

I've rebuilt the hubs on my 68 puck. They have inner and outer bearings, small outer big inner. On all three puck I've had they were all the same. Use a puller and grab the hub on the outside lip, should come off easy. Some of them will come off with a little tap from a mallet. The bearings look like wheel bearings from a swing axle but smaller. What seals the back side of the hub are two or three thin comp. rings like the rings in your motor. I never tried to get new bearings I got lucky and all the ones I've worked on where good. Clean your hubs, axles, and bearings. Repack with trailer bearing grease. Reassembly takes some time.

I wish you luck!!!!!

Mr.Armstrong

The info I have on the bearings is inside my head somewhere. The inner seals/rings can be reused. If the inside of your hub is not bad just hit it with #0000 3M pad till it is smooth. If the bearings are bad or if your spindle is bad it will need a face lift. The bearings are all metric in size and are a press fit. I'm trying to ease your mind here, these pucks don't weigh much so the bearing don't get much work.

Again I wish you luck,

Mr. Armstrong

If you have a good example you can most likely get correct sized bearings and seals from any bearing supply shop.

OK, I have the hub off now. Borrowed F-in-laws puller and it came off easy. Now, what I have left behind is the inner bearing, which I thought would have came out with the hub, but was mistaken.

So, how do I get the bearing safely off. I grabbed it, even litely put two flat head screwdrivers behind it where there is some space and gently pried to see if it would slide off. No luck. I am not going at it heavy, just gave it an easy go to see. My guess, the bearing must tightly grip the axle and is pressed on?

Anyway, any tips on how to get the bearing off. I can see the couple seals behind it that should pop off once I get the bearing out. I don't want to kill the bearings so if there is another tool to get something like this off, let me know.

Thanks

tj

Something like this should do it along with a puller.

http://www.amazon.com/Bearing-Splitter-2-3/dp/B000...amp;sr=1-2

You could just make a simular item out of some 1/8" thick (or thicker) steel plate. Would make it round like a washer with hole in center a bit bigger than the axle shaft. Then slot it out to one side and grind an angle on the side the slot comes out on. Slide the plate/washer and wedge it on inner side of the bearing. Then gently tap it down wedging between the bearing and axle flange. Once down in place use the puller to pull the plate and bearing the rest of the way off.

Mr. tj

I think I did the two screwdriver trick to get one of mine off. Give it a tap with a mallet but not enough to hurt anything. How do your bearings look?
Yes the bearings are a press fit on the axle.

Good luck, Mr. Armstrong
