I have not checked the archive to see if this has come up before.

I was wondering what the difference is between the front axle fitted to the J/P types and the ones fitted to the L types.The part numbers are different.

I spoke to Mike Allison earlier this week and he thought the L axle was the same as fitted to the J4. The difference is probably in the thickness of the "swan neck" part?

I have just fitted an L type front axle beam to my J4 rep. You are correct, the axle ends from the crank are noticeably thicker compared to the P type. Also, this one it has a greater axle camber

Good Morning George,

J2 and L2 axels are the same, have physical the same demensions,
the "Swan Neck" demension up to a Millimeter the same,
Both axel beams have the same forging number.
The J2 axel is stamped 72, the L2 72






cheers

I am intruded to know what I have just fired then. I was advised it was L type, stored 40 odd years and complete with its rack rods and complete brakes etc.

Comparing a J and L parked together I reached the same conclusion as Carl, no noticeable difference and measured dimensions were within a millimetre. The J-type axle is stamped “72” and I can’t see the stamping on the L-type (L1) axle. Cheers

I am sure that Carl is right and that J2 and L were fitted with the same axles - whichever ones were being made at the time.
However axle beams did vary from early J2 through to late P type and were progressively beefed up. I doubt if there is any record of when the changes occurred.
Some time ago when Colin Tieche was straightening axles for people he at one stage had quite a lot to do so one day we took dimensions from quite a few of them. We found three different types so if your axle has been changed in the last 80 years you could have any one of these fitted to your car.
From memory dimensions varied all over but the main difference was that some, which all happened to be from later cars, were definitely thicker in what George calls the swan neck section and around the king pin eye.

On the basis that the item was hot forged, there will have been tool wear over time. It may simply be that this is the source of the thickening of the cross sections.

Wonder whether all the axles came from the same Forge Shops?

Different suppliers could have resulted in differing measurements.

Well I typed 'intrigued' in my post. No idea where 'intruded' came from!

I do know there is a noticeable difference in sizes of axles I have here from the J to the P and the P to the L. I am also aware that the C/D had an axle cross section which was less than the J onwards. To clarify, like George mentions, I am referring to the 'swan neck' cross section only.

On the issue of tool wear, I would have expected any wear to be relatively constant along the axle length although of the different sizes of axles I have, these all appear to retain the same cross section measurements to the beam section, so I don't think noticeable thickness differences in axles can be down to any tool wear as there are noticeable thickness differences.

Tooling would no doubt have been periodically replaced so potentially an early L axle may be different to a late production L. Who knows although the L axle I have here is certainly beefed up.

Hi All,

When I bought a consignment of parts I was told that this was an L type front axel. Can anyone ID it for me?

The distance between the mounts is 540mm.













Regards,

Andrew
