Life of Puma Rear Diff's

Hi all,

Good to see there is still interest in this thread as we are getting close to having a diff ready for testing,

The new hypoid ring and pinion is made, 20 sets, crown wheel looks normal, pinion is huge !

Diff housing is drawn, pattern made and 2 prototypes have been cast and are awaiting machining now,

These will use our air locker and HD 24 spline halfshafts,

Will post up some photos once the housings are machined,

Dave

Serge, I was in no way advocating fitting one of these, unless 40"tyres are planned...:cool::twisted: These trucks are pretty heavy...

Just noting the size of them; even they have issues too apparently. a pair of D80 units :o are being about to be trialed in a couple of OKA now, Cummins 6BT and Allison1000 in front of them, and 40"tyres....

And mine was a big eight stud for duallies, full floater out our full size Jeep.

It wasn't a Jeep rear end, it had been swapped before Dad bought the Jeep, we think it may have been out of a Dodge or Inter, all I know it was ****** heavy :eek:

When I moved house in '96 I had a few different CWP's of various ratios and no longer had the Jeep so they all went to Sim's, then in '01 I bought a Deefer with a Sals......:(

It's incurable, they now come to you. Next you'll be putting drop boxes on them and steering knuckles onto rear axles for extra track width.

I've often thought D44 CWP's would make a good base to cast a drop in centre around.
Plenty of options for ratios and availability of good quality CWP's.

We are making a HD rear replacement diff unit to fit in place of the later P38 type 110 unit,

Naa, getting too old and cantankerous and hate getting my hands dirty these days, just a capable tourer is the aim now :)

Part fixed the track/steering issue of a 130 with Serg's Mach V's :D

Hi Dave, will this share the R&P from your force 9?

Since it is rear application only, did you consider making a new cast center to adapt ford 9inch gear sets so more availablility of R&P would be there?

Best of luck with it
