 Posted: Fri Feb 22, 2013 6:29 pm Post subject: Cv Joint P/N |
 |
|
Hi everyone,
I am confused about what the correct P/N is for a thing CV joint.
The parts manual lists it as a 113 501 331 d which would make it a Beetle part.
The boot is listed 411 501 149, a type 4 part.
What am I missing, or I am I stuck on stupid?
Regards,
Tony O. |

No, you're not stupid. The guy who worked at VW back then was for handing out a Beetle part number on a Thing only part.
That is the correct part number for a T181 CV joint.

That is the correct number for a 181/411/412 CV joint. I don't know why they assigned the part number they did. Sometimes VW would assign modification letters to parts to indicate "small" changes to parts already in production on a different model. Perhaps they considered the changes for the 411 (at the time) CV joint to be similar enough to the type 1 joint to carry a 113 part number with a modification letter. Remember that the 181 didn't get double jointed axles until midway through the 1973 model year, but the 411 went into production in 1968. Personally, I think the CVs are different enough to warrant a 411 part number or a modified type 2 number, but no one asked me (I wasn't alive then either).
I have a workshop bulletin dated 4 October 1973 (as well as another dated 15 February 1974) that indicates that the 113.501.331D CV is an updated replacement to the previous 113.501.331A. The difference being the introduction of gaskets to improve sealing of the entire CV assembly. Other parts changed as well at this time including the output flanges (went from 113.517.283A to 181.517.283) and the stub axle (181.501.263 to 181.501.263A).
However, I bought some NOS CVs a while back (NOS only because they were being sold for less than new German ones at the time) in anticipation of a future rebuild of the rear axle/suspension/transmission. I managed to purchase three 113.501.331D and one 113.501.331A in original boxes. I can find no difference between any of the joints and don't see any recesses for sealing gaskets on the 113.501.331D like the workshop bulletins indicate.
The correct 181/411/412 CV joint has similar dimensions to the type 2 CV joint, but should not be interchanged with them. The correct joint has more articulation than the type 2 joint. Some people claim they are stronger as well, but I can't personally back that claim up. However, I am told that the type 2 CV boot is interchangeable. I personally want to use Rockford Duraboots, but GermanSupply always seems to sell out of them quickly.

I have a pair of those type of output flanges. There's a recess for a gasket in them. I see no need to have a different part for the CV though.

According to the two workshop bulletins, the flanges and stub axles will have the recesses for the gasket (the cv won't on that side) and the cv will have the recess on the boot side. I regreased my CVs a long time ago, but I don't recall noticing gaskets or recesses for the gaskets in any of the parts (I wasn't really paying attention to that sort of detail so this isn't saying much). Maybe VW changed their mind again at a later date and I don't have a workshop bulletin for it (bulletins and supplements seem to have gotten rarer after 1974), but at least the NOS CVs I have all are without any sort of recess. So according to the evidence I have seen, there wasn't a need to change the part number of the CV joint.
