differences in atlas axles. last question on these from me! promise!
right, decided to definitely go with the 52" capri atlas axle, 6 bolt hubs available, as are half shafts etc... a few decent priced ones on ebay
at the moment too, finishing tomorrow.
question is though:
is there any difference in the axle case between 1.6, 2l, 2.8 and 3l?
basically all i want in the axle is the casing and diff. i'm told, ideally i want one from a 2.8, but whats different in these over the axle
from a 1.6?
please help! i'm about to bid on one of these tomorrow

hi there
as i remember the main difference between the 1.6 2.0 and 2.8 is the c.w.p
its 3.77 for the 1.6 3.44 for the 2.0 and 3.09 for v6 capris in addition th this theres also a thick tubed atlas fitted to the p100 range wich as the
name suggests has a thicker wall tube this will also have either a 4.66 or a 5.1 cwp and stronger planet and sun gear assembly
unfortunatly i have missed your other posts so am not sure what application your useing it for
a friend of mine has one for sale in west yorks if its any help its from a 2.0

cheers mate!
its going in the pickup, but i've had a lot of confusions as to what i'm going for... the racing pickups use an atlas axle, with special
hubs and half shafts, disc brakes, and 6 wheel studs.
really all i need is a case and diff. not too worried about the ratio at the moment tbh. i really wanted to make sure the tubes were all the same
diameter and thickness on all the capris, and that if i got one off a 1.6, i wasn't going to break it with a 3l engine
how much is your friend wanting for it? west yorks is a bit of a mission for me, but if these ones which are on ebay don't work out for me, and
your friends price is right, i could make the trip
oh, and btw, the P100 axle was an inch longer. not much, but could cause problems with the proper half shafts i need

yes we use the p100's as a base for the gp4 rally axles but we chop the end off so the lenths imaterial but caseing wise they are the strongest

Early 2.8 is non lsd, later ws LSD as standard, no other capri's were fitted with an LSD.
As far as I know you can swap the diffs ariund in the earlier casing without any issues, I certainly did this years ago taking out the diff on a 1600
and put in one from a 3ltr.

so they're all as strpong as each other? diffs shafts etc are all the same, except the ratio of the crown wheel is different?
i just don't want to end up with the wrong axle. it needs to be exactly right for the 6 stud hubs and half shafts to suit you see

All the Mk2 and Mk3 casings are the same, P100 casing is a stupidly heavy thing with floating shafts, some Trannys came with Atlases as well as some
Cortinas. All diffs interchangeable.
DO NOT PUT ON KNOB OR BOLLOCKS!

sorry mate I don't want to p**s on your chips but youd be better to find out exactly what the halfshafts you intend to use are spec'd at.
I have read somewhere (burton catalogue I think) that some of the aftermarket lsd's had shafts that had different no's of splines on them.
Prolly so they had to buy new ones at an exagerrated cost. If I were you I'd try asking around the pits at cowdie first to see if anyone had an
axle kicking about. They do mostly use english ones but they break up all sorts just to get boxes and engines.
If it looks wrong it probably is wrong.

^ very good point! SHP won't be open today... but Sonny did send me a price list for some of thier parts. half shafts are listed as 'Capri
type' although, for racing they do mostly use quaife diffs.
If i get a complete axle and the SHP shafts don't fit the diff then i've got the casing and thats some of the battle. if the axles cheap
enough and the diff doesn't suit the shafts, then i could sell the diff and original shafts on ebay, get some of my money back off the case.
though in saying that, i'm very confident the SHP shafts are the same spec as the ford ones and they just have a different fitting for the hub
on the ends

If theyre the same as the ones i've seen then they are capri type with a splined hub end which you bolt the hub onto with a castle nut/ split
pin setup. Presumeably he's adapted this to suit a variety of his own hub types sizes/p.c.d.'s. I'd still ask around the cowdie
guys.
If it looks wrong it probably is wrong.

thats what i'm thinking. they used to use alloy hubs with 6 studs, pcd was the same as toyota hilux, bedford midi, etc i forget exactly what it
is just now. 139mm or something.
alloy hubs aren't allowed in racing anymore, so a set of the alloy ones should still be around to be had.

you can get various spline diffs for the atlas most i think there 16 or 18 tooth i think english are 22 tooth
i know quaif do halfshafts to match either diff
and i think its 18 tooth standard
not sure if its any help to you tho

^ it sure does! cheers fella
i just won a complete atlas axle off a mk3 capri. *IF* the diff doesn't fit the half shafts, selling the original shafts and diff should result
in me getting the case for free, so not a major problem. the axle was rather cheap  worth the price for the case alone tbh

the spline difference is the side gears.
all the road atlas axles had the same splines, but for gp 4 rally use ford used bigger side gear splines known as zf side gears, to fit bigger
halfshafts.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

Mega Bargain although it'll be a 3.09 if it's from a 3ltr
OOPS need to read better a MK3 capri not a 3ltr

not entirely sure which one its from (which is why i was asking if they're all the same and as strong as each other)
the same guy is selling parts from 1.6, 2l and 2.8 capris, so could be anything. but like i said, as long as i'm not going to end up twisting it
or something, then its all good, and again, at that price, cheap enough to sell the diff and shafts and get the casing almost for free to put in my
own diff and the new shafts
well chuffed

depends on your gearbox gearing. I had a 3.90 that i swapped with calvinx for a bec project and now have a 3.77. It depends what you want I wanted
blistering accelloration (sp) up to 100mph and when i did a gearcalc for the 3.09 top speed was somthing like 165mph (theory) so I decided to go down
in ratio (or is that up) to give better acc but a lower and more realistic ( air drag etc) top speed.
If it looks wrong it probably is wrong.

at the moment, as long at it works, i can get new gearing for it later.
was just hoping there was not some major reason that a 3.09 would be wrong
