differences in atlas axles. last question on these from me! promise!
blakep82 - 1/9/07 at 10:29 PM

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


24vseven - 1/9/07 at 11:00 PM

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

i will dig out my mates number and u2u it to you as i am not to sure howmuch hes after if you have a spare p100 about i might be interested

sadly i don't have a p100 axle. there was one on ebay earlier, but can't for th life of me find it now. was cheap too. i've been searching for capri axle, and atlas axle


mark chandler - 1/9/07 at 11:21 PM

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.

Regards Mark


blakep82 - 1/9/07 at 11:24 PM

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


gazza285 - 1/9/07 at 11:53 PM

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.


blakep82 - 2/9/07 at 12:01 AM

^ nice one! again, exactly what i was hoping!


omega 24 v6 - 2/9/07 at 10:34 AM

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.


blakep82 - 2/9/07 at 10:59 AM

^ 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.


blakep82 - 2/9/07 at 11:38 AM

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.


24vseven - 2/9/07 at 12:38 PM

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


blakep82 - 2/9/07 at 12:52 PM

^ 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


NS Dev - 2/9/07 at 01:08 PM

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.

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

[Edited on 2/9/07 by omega 24 v6]


blakep82 - 2/9/07 at 01:32 PM

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

would a 3.09 be a bad thing though? its a 3ltr i'm putting in my car

depends how much aceleration you want


omega 24 v6 - 2/9/07 at 04:17 PM

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.


blakep82 - 2/9/07 at 04:22 PM

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


blakep82 - 2/9/07 at 05:31 PM

was hoping to collect it today, not heard anything from the guy selling its a 2 hour drive there, its getting a bit late to collect now...


24vseven - 2/9/07 at 06:09 PM

you can go as low as 5.1 useing standerd ford parts but as above top speed suffers my gp 4 escort has a 4.6 to a 4 speed box on 13 inch wheels and tops out at 96mph and thats with a 200bhp xe
gets there like f***n crazy tho lol


blakep82 - 2/9/07 at 06:14 PM

my engine was out an american ford van, so gearings probably not amazing for a car as light as the pickup's going to be.


blakep82 - 5/9/07 at 08:32 PM

picked up the axle last night. very nice its a 3.77 ratio from a 2ltr.

very pleased. whats the best way to clean it up for painting?

looks very little wear on the gears too

the actual diff

I tool mine into work and needle gunned it then wire brush in the drill.


blakep82 - 5/9/07 at 09:00 PM

i was considering sand blasting... didn't fancy getting grit in it though

what kind of paint did you use? been trying to think of what colour to do.

Answered your own question there I think. I used an anit corrosion primer matt black and then black gloss.


blakep82 - 5/9/07 at 09:17 PM

i quite fancy making some kind of a feature of it (it will be seen faily easily from the back of the truck) it like it to be really smooth.

nice one, cheers fella!


omega 24 v6 - 5/9/07 at 09:29 PM

You could get it chromed. But you'd need to strip and rebuild it prolly.


blakep82 - 5/9/07 at 09:36 PM

the cars going to be fairly noticeable considered a bright colour, yellow or something, maybe dayglo yellow... that or some other colour that really contrasts to the body, whatever colour that ends up.
