hi driving member for front hub part no512887 jim

The star shaped thingy part no 217378. On a 57 model SWB front, on a LWB front and rear.
.W.

The Series 1 drive flange continued on into Series 2, but about the start of Series 2a it changed from star shaped to full circle - these are interchangeable, and remain so right up to late Series 3 for vehicles with Salisbury rear axle - these had 24 spline flanges, and the fronts were the same. Last few of years of Series 3 used 24 spline even on swb with Rover rear axles.

At the Expo last month I sold a pair of them that I took off my Series 2 in 1963 when I fitted free wheel hubs. (Traded the S2 on S2a in 1965, and sold the 2a in 1969).

Nothing to do with OP , but a bit of trivia relevant to hub member / drive flange / spline count

Who thinks they know when LandRover first used 24 spline drive flange , most will say with the introduction of the Salisbury rear axle in the LWB Series 3 , when was that ... about 1980 right ?

infact the 24 spline was actually introduced in 1968 on all four corners on the Series 2A Lightweight , it was done because the spline length on the axle drive flange was only half as long as the 10 spline, and gave similar relative strength. This continued until about 1978 when they revised the design and began using regular style 10 spline flanges and axles because there was no longer a requirement to make the vehicle narrow to fit 2 side by side into a Argosy, the newer aircraft were much larger.

Actually the Salisbury was optional on the S2a from about 1968-9, and standard on all lwb Series 3 from 1971. The 110FC also had 24 splines from around the same time. And I have an idea some One Ton ones had salisbury axles, although I don't know when.

Thanks for all the replies.
I asked a well known supplier for confirmation of part number and interchangeability ( if thats a real word) between a drive flange from a 2 2 a or 3 to a 1 etc . I got the old run around for not using the right description - i was told a series 1 doesnt have a drive flange , only a drive member and that they were confused as to which one i meant - when i said the drive flange for the wheel , i was told there are 20 or more different drive flanges and which one did I want - which somewhat confused me. I kind of got the impression I had somehow annoyed the bloke by not using the correct form of words. People on here seemed to know what i was asking for - no problems. Its their loss - i’ll be going elsewhere with my hard earned cash.
cheers,

I think you have encountered staff who have very limited experience and are not familiar with Landrovers - hence, they cannot help beyond what is in their parts database. And worth noting that a lot of the later factory parts books do not have a description - just a picture and a part number, which does not help when you are on the phone, even if it is more definitive than the description.

And interchangeability is rarely specified in the parts lists - this is a matter mostly of experience.

To continue the tangent:

Actually the 24 spline flanges were first introduced 1964 when the Series IIA Forward Control changed to the ENV diffs, initially only on the rear and shortly after on both front an rear. All ENV assemblies had 24 spline flanges SIIA 549398 then SIIB (1966) 533578.
