series landrover CW&P set Question

[UrbanRedneck]

Just wondering if any one can tell me if the CW&P set from a series landrover will fit in a range rover centre with a ARB locker. They look like the same as a original rangy centre but before i pull them i would rather find out if they fit.
Differnces i know of are the coarse spline on the pinion of the series centre as oposed to fine one on rangy.
Apart from that i have no idea. Any help would be appreciated.

Cheers Damo

check the ratio's, a rangie is 3.54:1 , i think the early series landies are something like 4.7:1?? but it should say on the diff housing somewhere

Ye the ones i have are 4.7:1 thats why i am hoping they will fit in place of the original 3.whatever:1 so she can get some go go with the big tyres on her.

aparently they are weak as pi$$, i have some here in a series 3 if ya can't find any

[UrbanRedneck]

ok the arb listing list them as the same locker centre but they need a spacing ring and longer bolts. The ring is available from arb and the bolts apparently available from landrover.

MMMMMM 4.7:1 here i come i think:?

Ok next question is does anybody think that there would be a massive step backward with the coarse spline over the fine spline pinion. I would think the axles would still be the weak link.

OK well even so i spose they will get me along till i can afford to buy a new gear set.
Thanx for the offer i will keep them in mind but have been givin a set at the moment . If they are that weak i might need them anyway.

Any tire over 33" is going to act as a detonator for those 4.7s, unless you drive it like you're driving Miss Daisy.

I have read up that they recommend to use a four pinion or arb or a detroit carrier with these gears as it is the carrier that is weak alowing the ring gear to ride out on the pinion thus stripping the gears.
Do you think that pegging the diff may help with the weakness of these gear sets?
I only ask as i am on very tight budget as is every one now days and need to gear her for my 35's. And i already have these gears.

The ring gear flange on a 4.7 carrier is in a different spot to a 3.54 carrier. So you either need to use the complete 4.7 centre, or the arb spacer on your 3.54 carriers.

They are weak - mainly because of the fine 10-tooth pinion. However, Snarba on here has been running 4.7s on his play rig with huge rubber, and Mick Garner ran them on his comp truck with 35's - I think he broke a few, but I think the front was saved by stock RRC CVs/stubs.

I have broken one on the front of my IIA - with a naturally asthmatic 2.25 Diesel and 32s... I have had another fail on a different vehicle because the threaded section of the pinion snapped off, and the diff locked up.
