Life of Puma Rear Diff's

Naa, it was a genuine front end.

This one had a Rockwell Standard beam axle (2wd :o)

A brace of them were brought in for a mine contract, so the old fella at Stokoe Motors in Melbourne told me. (edit: this was back in the eighties)
I tried getting a kingpin kit and he wouldn't believe me it was 2wd until I told him which axle and quoted the model and serial, then all the info came tumbling out :)
He also had the kingpin kit, part of the spares package imported to support them.

I later fitted a D44 I had underneath her.

The old T98a Warner 'box had a near 7:1 first gear, real crawler stuff :D

Ah, sorry I thought it was an original 4x4 J3000.

My bad.

Still a big ugly yankee truck, though:p

This new diff will take our stock rover air locker and be 3.54 ratio, ie a bolt in upgrade but will require the prop to be shortened a little,

Dave,

This sounds very promising, I'll certainly be following with interest.

So apart from the shortened prop shaft there is a new pinion housing and all new internals including your HD half shafts ? Will your limited slip ATB be able to be used ?

Yes, new housing, new ring and pinion, takes stock rover diff bearings, stock seal and flange, uses rover (non P38) diff centre, locker , ATB, whatever, but with larger crown wheel bolts so the 10 holes will need drilling out to suit,

HD shafts are optional,

Dave what is the design based on? eg D44 etc? Is it also a low or high pinion?

Hi, it's not really based on anything, just to our design,

It's a low pinion,

They are a good material, plenty of hypoid offset (1.5") means more teeth in contact , chunky teeth and bearing are further apart than the P38 like the rover,

Should be quite strong,

Dave

Thanks Dave, I really love the work you're doing with Land Rovers - such an innovator.

Just as I think it through, it really sounds like its going to be an excellent diff, like really strong compared to Rover and beyond that of those Toy 8" conversions too.

If you don't mind me asking:

Is this setup that you're developing able to be used in front applications, so provides clearance for the tie rod also or has it been designed as purely a HD rear diff option?

You were saying previously that it accepts other Rover type hemispheres - eg old style ARB, Maxi etc with holes drilled out to a larger dia.

Does the pinion use Rover 4 bolt or 3 bolt flanges.

Which ratios do you expect to be available?

Is this something suitable for upgrading half shafts to Toy 30 spline, D60 35 spline if clearance etc?

Is it suitable for Rover housings also or only P38 type?

Sorry for all of the questions, I just think this is such a great development for LandRovers.
