Got nothing to do with balls! but i did make it my self!

the rear prop in the 90 binds with the rear wheels off the ground. thanks to scouse for finding this for me.
so over the past 4 months ive been looking for a way to fit a stronger/greater angle tail shaft in.

101FC(1310) stuff will fit but every option i came across, that was bolt in, had the small 1300 series uni.
i wasnt about to spend megga bucks to import one or get one made here in oz. so i was under the 90 looking at the front tail shaft and noticed that the front uni's are huge compaired to the rears.

fronts are 1330series. 27mm caps and 92mm cross
rears are 1300series. 27mm caps and 74mm cross.
101FC are 1310 series. 27mm caps and 80mm crosses

load ratings are; 1330. constant 162Nm short 815Nm
1330. constant 203Nm short 1206Nm.

so i found a front td5 shaft at the right price, thanks tombraider! and started the cut up job.

a re tube costs $220! and thats just to add the 140mm i was short! the same tube cost me $43.00 thats enough to do 2 shafts...

the rest is cutting the ends off and lining everything up and welding together.

old shaft front with yoke cut off.
new length of tube at rear.

slip joint now fitted to new tube, ready for welding.

shaft ready for painting, and or ballancing, if it needs it.

the only thing im not sure is why the front shaft is phased and the rear isnt??

cheers phil

ps. ive done this before!

Excellent work Phil...

I love reading of your exploits! They're always first grade work.

Keep up the good stuff mate :cool:

Tombie!

Thanks for sharing that Phil. You have given me something to investigate further for my stuff.

AFAIK early rangies had wider angle uni-joints than later models.

As for the phasing of the uni-joint on front driveshafts. It is to compensate for the unequal angle changes that the t/case uni makes, compared with that at the front diff end.

Because the engine and transmission is angled up at the front on coil sprung rovers, it is not practical to have the front diff pinion parallel with the front output shaft from the t/case.

This does not apply to the stage 1 or disco II, because they use a double cardan joint at the t/case end.

heres the differances between the old rear and the new rear.

the uni's are quite a bit bigger, well for a LR part anyway...

i was told this too, something like classic RR were bigger? their the same as all D1's.

thanks for that, makes sense.
