SINGLE RAIL GEARBOX INFO

[Thom 6,708]

also the gear stick position of the AU T5 is further back from what i was told.. need to verify that. but just another potential pain in the ass

Gearshift is 30mm further back on an au box

Just a heads-up for anyone still running these old beasts, a bloke on an XD-XF Facebook parts group is flogging his shifter pivot kit, turns it into a short-shift and eliminates the nylon thread issue.

Dunno if you need to be a member to view though.

Hi Does anyone know what a single rail 74 BA-7003-AA, 0503 014. I have researched the codes on this thread and have not found a mention of the 74 BA, all 74 codes seem to start with 74DA, not BA so i am wondering if this is a significant change.

Putting that aside there is no mention here of what a 0503-014 is out of

Thanks

Steve

Hi all

New on here so here goes, hope I'm not going over something already covered.

I'm doing a resto on a 79 302 XD S Pack that some fool has converted from 4 Speed to auto. As I understand it I need a 0503 009 single rail what I am not sure of is the  casting numbers i.e. 7? DA-7003-AA . Does the number after the 7 equate to the year of the car and should the AA mean that model as well. I have a couple of gearboxes lined up but aren't pulling the trigger until I'm sure.

Great info on here

Cheers in advance 

Britto

The first set of numbers is the Ford part, but that one doesn't make sense. Normally the US part number is letter-number-letter-letter, then specific part number, normally 4 digits, then 2 letters for design variation. The Aussie part numbers used to be the US one with AR (Australian Revision) added to it, then they came up with their own that had 2 digit year, then DA (Design Australia). Yours doesn't have the year before it. The 7003 is likely part number.

 

The second set of numbers is the Borg Warner one, 0503 is for the single rail box, 009 is the variant (ratios, shifter and rail config). That variant, which with a Google search came up with OzFalcon as one of the first shows as a 3.06 first gear, meaning it's a medium ratio fitted to 302s and some 250s (depending on application, year model, etc). The wide ratio has 3.48 first, the close ratio (fitted to 351s) has 2.46.

Sorry just re-read your post and realised the 7? Is the 2-digit year code, you were just eluding to a hypothetical year. Say it was 75DA, it doesn't mean the part was necessarily made then, it means the year that the part was first introduced. So if a part continued to be fitted unchanged many years later, it would still carry the original year that it was first installed.

Thanks mate, so I would be safe with say  a 74DA-7003-AA ?

If it fits in the hole and is the right ratio, can't go wrong... I don't think anyone cares about it being the right box for originality reasons. Most folks who care about matching numbers are only concerned with engine and chassis matching.

Can anyone help with identification of this Borg Warner 4 speed, all I know is was behind a 302c in a XE falcon. 

Have purchased it as a combo for my 351c.

Surely it's not a 6 cylinder one as am I correct in thinking the input shaft count would differ. 

 

Cheers

pretty sure that one is out of a TE cortina 6cyl,i did some research into single rail tag numbers some time ago as i had some with similar 014 and 017 numbers.

Thanks, so knowing my luck the input shaft is the same perhaps. 

Ya reackon it's gonna handle the jandal behind the 351c,it'll probably get thrashed in 2nd & 3rd but no burn outs. 

All the gears under the plate looked in really good knick & oil was clean as a whistle 

(Probably built in 78 though aye)

Hey Guys,

  I just picked up a 1984 XE with a 351 Cleveland and 4 speed single rail.  The shifter is fairly well jacked up (I believe, I only just got home and haven't pulled it out yet).  When in gear the shifter can be moved nearly an inch from forward left to back right.  The wiggle from left to right in gear seems pretty good.  Also when shifting into gear the shift is very, very heavy and short.  Does this sound like a shifter issue that is common??  Do the 4 speeds shift better with or without a short throw??

depending how worn out the whole thing is..

i had my first one 30yrs ago with the shifter housing worn where the selector rail goes in (bushes were fitted if it didn't have any, and the shaft was turned down a bit on a lathe as it was also worn) 

this could be the for and aft movement you mention. 

the side to side and for and aft wear is often due to the "horseshoe bush" but some single rails never had them, and were metal on metal (would be hard to fix)

 

the old way for a shorter throw was to cut the shifter down, but someone has made a short throw for these now (mentioned on this site, but i haven't seen anyone who's bought one yet. )

 

personally i'd prefer to repair what's there and leave the shifter standard length. i'd be more inclined to make sure the gearbox is in good condition first, and replace the selector shaft seal (requires extension housing to be removed)

Dale Gollan on messagener or a few other Facebook Ford X series pages offers a very good shifter replacement.
