Zephyr I6 Clutch Won't Disengage Missing Information

[Stormin' Norman]

I'm getting to be a Serious Number, just looking at the transmission tag.

RUG DE GK26
E0ZR EA 2082

I know its a 1980 SROD - E0ZR

But no one of the big rebuilders or resellers lists the RUG DE, just RUG D, D1 or D2, and what does the "GK26" mean?

If all else fails... RTFM! My Ford Factory shop manual is for 1979 Ford cars, but doesn't show the SROD/RUG tag. Another missing bit of data:

Henry Ford said


"We'll build it as best we can, and if we dont use it, someone else will".

Ford and Mercedes make money by on selling there production process investments. So the TopLoader became the SR4, SROD, RUG by consulting work done for FoMoCo by three other suppliers. AMC and Jeep used Ford gearboxes and electrics and carbs. And Porsche 928's and Sasyong Musso's used to get Daimler Benz automatic gearboxes.

The little imported Ford 4-speed Type gearboxes came from Dagenham initially, and then the German Rocket and Hummers got out sourced as Borg Warner Singal rail in Australia, the Tremec T140 and 170 series in South America, and then those companies put there own 5th gear clutster and extension housings on a Ford gearbox. Would you believe a Toyota with a Holden engine and Ford gearbox by Borg Warner Australia? Or a Nissan pickup with a Ford based gearbox by Tremec, Belive it!

Ford of Europe did a 5 speed overdrive version of the German 4 speed themselves to create the Ford Type 9 gearbox.

So the apple doesn't fall far from the tree, but the gearbox tags only cover the makers details and if made for a Ford, Fords basic part number requirements.

In keeping with a bold move for the mid seventies, FoMoCo's Dearborn team farmed the 3.03 design out to urgently get a better, lighter, less heavy duty gearbox, a classic price verses quality trade off over the more expensive 5 speed over drive option. Ford always knows how to reduce the cost of components. sometimes by outsourcing, sometimes by doing it in house, but mostly by outsourcing.

In so doing, you ensure supply if there is a strike, and you improve the quality price tradeoff.


There are many different suplliers of iron or alloy case Top Loader OD based gearboxes. Ford, then Orion, Borg Warner, and, IIRC, Tremec. But there were cost shaving and optimised inventory variances each time. If any of the four transission builders had a part in stock, they'd redesign there SR4/SROD/RUG/RAD to suit a new part, and in so doing, the 4 speed Ford Toploader morphed out into using Borg Warner T4 parts, or Tremec T170 parts.



Eg Your 1980 SROD

RUG DE GK26
E0ZR EA 2082

DE - Class D Prefix is the Ford Letter size vehicle (compact, with Suffix E the compact break down for Foxes.

GK26 Date Code

Eg AN 82 TO 87 truck SROD

RUG EM DC17
E2ZR AA 2914

EZ - Class E Prefix is the Ford Letter size vehicle (full size truck), with Suffix Z the full size break down for Foxes.

DC17 Date Code


Eg the 1979 2.3 Turbo Mustang/Capri RAD 4 speed Singal Rail

RAD YK 278

D9ZR EA 112061

http://vb.foureyedpride.com/showthre...E-transmission

Eg 1979 3.3 or 5.0 Mustang/Capri trans

RUG DE DA9
E0ZR EA 0650

RUG (= SROD) _ _ = trans model code _ _ _ _ = build date

_ _ = BPU year and _ _ = Car model _ _ _ _ _ _ = trans part #(last six aplha numeric)

10001 = production # / last 6 #'s of vin

RUG DE
DA9 = built April 9, 1980
E0ZREA = manual transmission (R) originally engineered for 1980 (E0) Mustang (Z), revision level EA
0650 = transmission serial number

And lastly, that German based, Ford US engineered example of a 4 speed with a bolt on Overdriven 5th.

Eg 1980-1983 U shift 5 speed behind 2.3 Lima A code and the various 1980 US and 1981-1983 Canadian Carb Turbo W codes

RAP AG LB27
E1ZR NA 0658


This info below is now somewhat out of date, as there was rapid change to the BPN sequence with the advent of the modified S shell Fox Fords (the 1983 Thunderbird/LSC/ LWB Cougar and LTD's) and they were now supplied by a secondary supplier with its own system, but

http://automotivemileposts.com/ford/...rtnumbers.html has the older numbers.


Lots of issues. B and D interchange, the second suffix letter varies.

TYPICAL DATE CODE:

There are other kinds too Xctasy

9A21

9 = Year (1949/1959/1969/1979/1989/1999) Actual year can be determined by checking the part number of that component for the decade code.
A = January
21 = 21st Day of the month

We'll say the part number prefix indicates the decade is the 1960's, so 9A21 is decoded as being built on January 21, 1969. (Yes, we checked...it was a work day.) And sometimes, the date code can be stamped in the wrong order, as in the example shown above. We're going to guess that the "79C" code should have really been "9C7" which would designate a casting date of March 7, 1959, which would be a correct date for that particular part.

MONTH DATE CODES:

A - January
B - February
C - March
D - April
E - May
F - June
G - July
H - August
I - (not used)
J - September
K - October
L - November
M - December

You and FoxChassis should open The Fox Library. I've got links to about 30 NOS vendors, so as our Foxes replace the Model T, historically speaking, That info will become strategic to keeping them around in prime condition.

My car is reassembled. Adjustments today. They shut down at noon today, until Tuesday AM, for Christmas. Works for me, because we're getting another 30 CM snow dump, from late today until Monday PM.

Merry Christmas, down there so close to Christmas Island.

...New flywheels are almost impossible to find...

National Parts Depot has '66-'67 200 flywheels p/n 6357-21A. Visually it looks the same as the used one I harvested from a '79 or so Mustang.

I'll check that out. I've read, here and there, that the old V8 flywheels are interchangeable. Where's a Hollinger book when you want it!

Thanks Dean_T, Oh! Merry Ho Ho! :0

Well, after this adventure, here is why my new clutch cable broke and why it wouldn't disengage.

The clutch plate was oversized on the diameter. The shop had a 'seasoned' mechanic/machinist who knows Fox stick shifts, and some of the issues that plague them. He had the younger mechanics reassemble the trans into the bell, and tested it for himself. The clutch was just over 1/8" oversized, enough that the pressure plate couldn't move into place. They also changed the pressure plate bolts from the cheap cadmium-plated bolts that came with the kit to ARP bolts.

She runs like a champ! What a difference with the rear swaybar and posi-trac! No dipping, just a tight suspension all around. Awesome!

And since Ford didn't write their manuals with after-market vendors in mind, I forgive them for not cautioning to check the diameter of the clutch plate.
