Halibrand Quickhange Rears

[Russ Gaylord Fontana]

I'm thinking about the possablity of fitting a quick change rear to the model A rear axle on my sprint car. Does anone have experience of these, obtaining, fitting, etc (I do realise that they aren't cheap)???

[Banger]

Have a read of Darren's build up of a Kiwi Quickchange here.

I've got the same unit under my Model A and I can't fault it. Nervous Bob did the machine work and axle assembly for me and again his work is first class. I believe it's a fairly accurate copy of the Halibrand unit. It uses Winters gears which are around $60 a set.

Thanks for the reply, I found this one www.dickspadaro.com/quickchange.html from the states, it says it's not for racing or high horse power engines, how have you found the one yo've fitted? Could you give me Bobs number and an idea of the costs involved?

The above post doesn't seem to allow me to use the word d i c k in the www.address and put in richard instead....what else can it do???

I have done a few with 9 inch half shafts as well which can handle up to 400hp. Just in the middle of doing an A-axle with 9" shafts and a locker diff for Duncan Bell (one of the vintage stock car boys at the Hay-ride).

[Banger]

Bob's number is 01359 230027. I can't remember how much I paid Bob to be honest, but I did need a new ring gear (mine had a few teeth missing) amongst other things so it wasn't an entirely straightforward swap. The centre section itself was something like £650 but I sourced the gears myself as I wasn't too keen on the ratios they supplied.

The D1ck Spadaro unit is for V8 rear ends so won't work with a Model A. Other than finding a vintage piece I believe the Kiwi quickchange is the only option currently available for Model A axles, though I'm ready to be proved wrong.

I'm running a hopped up 4 banger in front of mine so high power really isn't an issue!

[Russ Gaylord Fontana]

Just shows my lack of knowledge on this stuff, but still scouring the net for more info. On an old HAMB thread Cyclone was mentioned, but more expensive, www.cycloneracingequip.com/contact/cycloneracingequipment.htm
anyone know any more?

[Banger]

The Cyclone unit is a good piece but again only for the V8 axle. Are you certain that you have a Model A rear?

Jim, what quickchange are you using on the A axle you're building?

[Russ Gaylord Fontana]

Yes, model A rear, so I'll stop looking. It seem that most of the quick changes are for later axles, just hopefull I guess. Thanks for the help so far....

[Enbloc]

Just in the middle of doing an A-axle with 9" shafts and a locker diff for Duncan Bell (one of the vintage stock car boys at the Hay-ride).

An 'A' axle with 9" halfshafts?!? Is that your own doing or a modified Hot Rod Works kit?
Does that incorporate safety hubs as well?

Whats the locker? Spool or welded up diff or...??

[Hot Rod Deuce]

Russ, if you get a copy of the Rodders Journal number 26, there is a full list and info on the quickchanges available.There is also a good article in Car kulture deluxe issue number 12, it gives a full 8 page article on stripping and rebuilding an banjo rearend, with 34 how to pictures.

I`m running a Spadaro qc in my latest...open drive behind a T5 box.//

[Russ Gaylord Fontana]

Thanks 'Deuce' I need all the help I can get....have just discovered that I haven't got an A rear (have got an A front though) but in fact it's a '39....somewhere along the way it might have helped to remember, I should engage brain before typing!!!!!!!!!!!!!!!!!
So it seems there's more choice on the quickchange front with a later axle. So far, from what I can gather (all done when too tired to concentrate) that the 'cyclone' is the toughest (not really sure that I need the strength with only 135? hp) but also the most expensive and 'winters' the most used.
So it's out to look for some more mags.....any excuse
Cheers, Mike

[Banger]

135 horses isn't going to be a problem for any of 'em. Now it's down to personal choice of which you prefer the look of and suits your pocket best.

[Russ Gaylord Fontana]

I think the next question then, is how to get more horses in there, as that seems the only way to justify paying more than I should for a quickchange!!!!
I think I might need help

[32vertex]

Here's my question on this (maybe this should be posted on the techpage) how can I tell exactly what banjo rear i have ? I ve been told it is a 1936 Ford rear, so that would make it a V8-rear ? Is it in counting the bolts on the axlebells ?

[Banger]

It's a little more complicated than counting the bolts I'm afraid. Rather than try and explain it, I've scanned this lot in which should answer most questions about identifying early Ford rear ends.

Niel, the A axle quickchanges were the kiwi units. Clarke, the 9 inch kit is was a modified Hot Rod Works kit with slide in axles, the diff is a machined unit which fits in where the spider gears would normaly fit (i will try and get a photo later today). Erwin, heres how to tell.


Identify Axle Housings


There are 7 basic styles of axle housings.

#1) 1928-1931 'A'. The bell is 9 3/4" diameter. The spring perches are on top of the axle tubes near the backing plate mounting flange.

#2) 1932 ('A' style). The bell is 9 3/4" diameter and the length is 24 1/8" from housing gasket to backing plate flange. The spring perches are attached to the backing plate flange. The radius rod tabs are straight.

#3) 1932 (V8 style) and 1933-1934. The bell is 10" diameter and the length is 24 1/8 from flange to flange. The spring perch is attached to the backing plate flange and is shaped like the '32 'A' style. The radius rod tabs are mounted on an angle.

#4) 1935-36. The bell is 10" diameter and the length is 24 5/8" flange to flange. There are no spring perches. The spring was mounted on the radius rods. These housings have an oval flange to which the radius rods mounted.

#5) 1937-40. The bell is 10" diameter and the length is 24 5/8" flange to flange. The spring hangers are attached to the backing plate/housing end.

#6) 1941. The bell is 10" diameter and the length is 24 5/8" flange to flange. The 1941 housings have a small triangle shaped "nub" by the spring shackle hole, and a stud on the passenger side spring hanger for the pan hard rod .

#7) 1942-1948. The bell is 10" diameter and the length is 25 1/2" flange to flange. These have an extra stud on the spring perch for the pan hard rod.

Damn, I'd forgotten about the ID guide on the Hot Rod Works site, that would have saved me a whole heap of time scanning all that stuff in! Here's a couple of links to the info there.

Thanks Banger ! I found a centersection on ebay (haven't bid yet) http://cgi.ebay.com/ebaymotors/Parts-Accessories___SPRINT-MIDGET-CAR-REAR-END-ASSEMBLY-quick-change-ping_W0QQitemZ120296024650QQddnZPartsQ20Q26Q20Acce ssoriesQQddiZ2811QQcmdZViewItem?hash=item120296024 650&_trkparms=72%3A543%7C39%3A1%7C65%3A12%7C240%3A1318&_trksid=p4506.c0.m245

It is a bit diificult to establish if that will fit my 36 axle (which my axle is according to the info given here).
Can any of you quickchange specialists confirm this ? (and not outbid me afterwards LOL !)

[Banger]

Given that it's an old race car piece and has a crack in it I'd pass on it to be honest. If it needs any machining, repair or whatever it could end up costing a pretty penny. That's to say if it even works with a V8 Ford rear end. There are enough choices out there for new and used that I would wait till a better one comes along.

[32vertex]

"That's to say if it even works with a Ford rear end"
You're supposed to build the stock Ford diff into the quickchange housing, ain't it ?

Pass on is the better option, I know, allthough I have access to a good and cheap (as in free) machinist, I will be banging my head against the wall, if it sells (no reserve) for $200....I allready enquired, shiipping is $112. (buy it now!, bu it now!, buy it now!!)

[Banger]

I've done a bit more digging around for you, the casting number 101 would put the one your watching as being for a Model A, if it were for a V8 it would be numbered 201. For further reference and searching on ebay, the Model A quickchanges are also known as Midget axles, so you need to avoid those as well. Oh, and Champ stuff is numbered in the 300's.

Are you perhaps female Banger ? If yes, consider yourself hugged now !

Thanx for taking this kinda trouble, to keep me out of trouble !!
