Is this from a carrier
 

Hi all , is this from a carrier ?

cheers dave

I think it's a vehicle prop shaft joint. I have similar looking on my Morris Commercial but it has rubber joints. Whatever vehicle it's from must have more nipples than the Luton Girls Choir!! Ron

Duplex coupling
 

Hi David yes its a carrier duplex coupling conecting the gearbox to the diff

Ron P. Some of us are now waiting for that particular picture :D
Ron W. because these are such complicated pieces of engineering did they last well?
And..... were these early production, replaced with the rubber bushed type?

Hi Lynn, not trying to answer for Ron but regular maintenance on this particular joint is paramount, it states in the maintenance book that not greasing even one nipple is just as bad as not greasing the whole joint at all. It is quite a complex part if you ever get to pull one apart and you can certainly appreciate why it requires so many nipples :eek: In my opinion, I don't think it was an early production joint as I have seen them on late model carriers as well as early ones. Like with most things, I think I would have came done to parts availability at the time and also manufacture preference as to whether to use this coupling, the 8 point coupling or the muff coupling. From memory the 2pdr and 3' mortar carrier use the 8 point coupling in there drive lines.

I have seen muff coupling pictures, but never in the flesh. Were many used?

Hi all , due to to many offers have listed on ebay tonight ( Sunday).

cheers dave

coupling
 

I believed this type of coupling is the early type because it is used on the 1938 -40 Ford axle. This axle has the spline pinion , where as the later 1942 was tapered. This coupling is splined both sides , one for gearbox end and the one for the early axle splined pinion. Correct me if I am wrong on this.

Thanks Andrew If they were not made with anything but splines, that would confirm them as "early" (as I suspected)

PM sent David.

I have 3 of these duplex couplings and all 3 are tapered on one side and splined on the other....

I agree with Andrew for Kiwi LP2 carriers.
 

NZ seems to have used them only for early LP2, and gone for the rubber bushed flanged coupling on later production LP2A.

Our LP2 had the early one, but one ball had frozen and it was flogged out.

An LP2 in southern Wairarapa NZ had one fail in spectacular fashion in the early 80s when it seized and rotated the gearbox off the back of the engine!
The carrier was going again a week or so later, but the monkey face CMP project in the shed never got completed due to lack of its engine!
