Bus wheel bearings...

Post by Merlin »

's up all?

Quite some time ago, Armand (IMPI) responded to a query I hard regarding the bearing numbers for bus rear wheel bearings...

I unfortunately had this info stored on my USB drive which got scaled :evil: , and now need it sooner rather than later, read: 'today if possible'...

Do any of you happen to have all the bearing numbers for the rear, and how many of each I need to replace both sides?

Thanks! :)

...I'll be buying from Bearing Man, unless you can recommend somewhere else too.

Cheers, N.

Reduction gearbox bearings for split bus:

N207E
6305
6306

There are four bearings in each RGB, so you need two of one of them, either the 6305 or 6306; I can't remember.

Eish!

No-one in Jo'burg seems to know how many I need! :o

Anyways, I'll seee what samples I have, and confirm with IMPI over the phone tonight...

As for the N207E, I've just cleared out Bearing Man's entire stock countrywide!

*lol* :mrgreen:

I had the info stored, but as stated, some @!$%^&* stole my USB drive sooo...

Which bearing is which, and which [a; b; c; d] do I need 2 of per reduction box?

Thanks! :)

Cheers, N.

Hehe...

Strangely enough I've used that phrase often this week. ;)

It was the "44mm socket" thought that made me think "big nut". :mrgreen:

Thanks, N.

Small nut = 36mm axle nut.
Big nut = 46mm axle nut

You will also need a 41mm socket to remove the stub axle, as well as a special puller to remove the steel plug at the back of the RGB.

Eric's doing 'em for me. :) I'm running out of time, and need the bus 100% as I'm taking to the 'berg in 2 weeks.

The engine's coming out for a retorque of the heads, and a general tune-up, it's getting new wheel-bearings, and a period radio is going in. :mrgreen:

I'm buying bearings for the ambo too, as that will be done later this year...

Thanks for the help! :)

Which bus' had small, and which big - and why the change?

Cheers, N.

Buses up to 8/63 were small nut and after that were big nut. The change coincided with the 1500 engine becoming standard and the brakes being uprated to match.

There was a period in 1963 where one could order the 1500 engine as an option, and those buses have one-year only rear brakes with the larger drums but still a 36mm axle nut.

The small nut RGBs are much easier to rebuild as they don't have the 41mm nut on the back of the stub axle and the associated metal plug, which is press fitted flush and needs a special puller to remove.
