 Posted: Fri May 06, 2011 4:24 pm Post subject: Confusion regarding rear drums on 1963 Bus |
 |
|
Hi everyone,
I recently have been having problems with my rear drum making a grinding noise so I had a look yesterday and there is a bit of play with the drum and axle on my 1963 split. For some reason I had in my head that the rear drum had a part number of 211 501 615 D, anyway today to make sure I pulled the rear drum off and the number was 211 501 615 B?? I really dont know where I got the "D" from but anyway...(might of got it from the front hubs or something)
So I have tried looking for this drum with the "B" part number and cant find one, so I googled the number and sort of came up with the conclusion that "B" is for brazil but mine has a VW sign on it..
So my question is how do i figure out what hubs I need? It has a 36mm stub axle nut..And its a 1963 model, thats about all I can tell you at the moment..  
Cheers
Dave

Thanks for that srfndoc, I did read that in a thread, so would I need the 211 501 615 D - Bus 62-63 w/Big Axle Redux Boxes & Brakes (M216) ??
Not the 211 501 615 A - Bus Mar 55-Aug 63?
It has a small stub axle nut (36mm).... |

Thank you mtb7001
I just looked up the part numbers and both the "A"and the "D" part numbers are both up to chassis number 1144281 which mine is before this chassis number, though it says the "D" has the M216 option which is the 1500cc engine. Now mine being an Aussie built 63 it doesnt come with an M-Code plate but it does have the bracket for the air filter on the top left side of the engine bay which suggests to me it had the 1500 engine...
Which would make it the "D" part number the one I would need..(I think)
So what are the differences between the "A" and the "D" rear drums?
Is it the rear axle size??
The "A" has the 36mm nut and the "D" doesnt?
I dont know. 
Cheers

Both those have a 36mm axle nut. The 615 D has a longer stub axle and the drum is longer/sticks out farther to compensate, they are not interchangeable. You need to look closely and compare which you have. Post a pic, might help. |

Ok, how much longer is the 615 D compared to the 615 A? |

This is not really a correct description, it's more like:
211 501 615 D - Bus 1963 only w/63-only reduction box ratio and 64-67 style brakes (M216)
If your Bus has the air cleaner hanger welded to the left side of the engine compartment, it should be an original 1500cc Bus and should use the D brake drums, assuming nothing has been changed along the way since it was new.

Thanks EverettB,
I remember I had the later 64 on wheel cylinders and shoes, if that helps also?
Cheers

Yes, those drums use the later brakes.
I have a '63 1500cc 15-Window with all the original, or at least correct, rear end parts on it. The axle seal parts and some other parts are also unique but apparently I don't have any specific detailed photos of them.
Here's my axle nut if this adds anything
And my driver's rear axle sticking out:
And my axle seal cover:

Just waiting for the battery on my camera to charge, though the wheel is still on but the hub cap is off.. 
The axle nut looks the same as yours Everett, I knew I should of taken pics when I had the drum off.. 
I have had a vw mechanic put "new" or original axles in it about a year ago and knowing him they would be the right ones or the same as what came out. Its hard to read the receipt he gave but it says 974 Axles?? Not sure what that means...
Hurry up and charge battery!! |

Ok here are some pics, notice in the last pic where the hole is through the axle for the split pin, as to where the nut is..There is a bit of room I think for a bigger drum but not sure how much bigger the 615 D is compared to the one I have is..(The 615 B)

I suppose the only way for me to be sure is to take the drum back off and to measure the diameter of the drum.. So if the diameter is 250mm that means the 615 D's are the right choice...I think
Judging by this thread
http://www.thesamba.com/vw/forum/viewtopic.php?t=459107&highlight=drum
He has the same 615 B drums that I do so they should be 250mm..
We will have to wait and see..
Cheers

I have a pair of drums, 1 is a D and the other is B. They looked the same to me but I can measure both and post my findings .

It turns out my new parts transaxle is a 63 small nut 1 ton.
I measured the depth of the drums from the 63 (part # 211 501 615 D), end of snout to inside edge at 125mm
I measured a small nut drum (part # 211 501 615 A) at 115mm.
10mm more depth on the D drum.
After searching a bit on the 63 1 ton, it appears that there are a lot of differences from both early and later RGB's.
Both RGB halves, spacers, stub axle, bearing cap, axle nut, brake drum are unique?
Backing plates, brake shoes, brake hardware, brake cylinders, gear ratio are the same as big nut?

Excellent, thanks Riff Raff.
Now I wonder what the measurement of my 615 B is going to be.. |
