1966 F850? help please

Hello all, I recently purchased a 1966 F850??? vin# F85LU868852... Single rear axel dump truck. Max GVW "27500" LBS per VIN tag but CA DMV states "30,000", W.B. "212", Model "F857", BODY "481", Trans "F".


It has a 6V 92 Detroit Diesel mated to a Eaton fuller 13 speed transmission.


The truck came without a clutch Master cylinder and I am having a very difficult time trying to locate one. Any help with information on this truck will be greatly appreciated. ill be attacking photos shortly.

Sequence as listed on the Warranty Plate:

WB: 212 / COLOR: Omitted / MODEL: F857 / BODY: 481 / TRANS: F / AXLE: Omitted / MAX GVW LBS: 27500 / CERT NET HP: Omitted / RPM: Omitted / DSO: Omitted.

It has a 6V 92 Detroit Diesel mated to a Eaton fuller 13 speed transmission.
Engine & transmission have been swapped.

The truck came without a Clutch Master Cylinder* and I am having a very difficult time trying to locate one.
F85 = F850.

L = 534 4V (gas) or Caterpillar model 1673-B 525 cid 6 cylinder diesel.

U = Louisville KY Assembly Plant.

868852 = 1966, assembled May 1966.

212" Wheelbase.

F857 = F850 .. 27,500 lbs. GVWR

481: 4 = Medium Beige Crush Vinyl & Medium Beige Wicker Pattern Vinyl / 81 = 81A Standard Cab.

F = Warner T-98 4 Speed or Warner T-18 4 Speed or Fuller model 5H74 5 Speed Direct.

27,500 lbs. Gross Vehicle Weight Rating.

C1TT-7A542-A .. Clutch Master Cylinder-less pushrod / Obsolete

1961/62 F750/1100 / 1963/69: F800/1100 & N850/1100 & NT850/950.

No Ford dealer or obsolete parts vendor has any.

If you also need the master cylinder pushrod (C1TT-7A541-F), there are at least 17 available NOS

Parts catalog pic: 7A512 is the hydraulic line between the clutch master cylinder (shown as black triangle) and the clutch slave cylinder (7A508).

*Did you check with the person you bought this truck from to see if the clutch master cylinder might be laying around somewhere?

People take these things off in hopes of getting a new one or a repair kit, then cannot find either.

If you can find it, there's a repair kit (C1TZ-7578-A). So far, I found 49 of them NOS

C1TT7A542A crosses over to a Dorman CM36126. Might be obsolete, but you could try searching for that number too.

More Information for DORMAN CM36126

Love to see a picture of this truck, like to see how they got a 6V92 in there!

Thank you all for the great info pics and part numbers. I'll be ordering one today l if they actually have one. Hoping the first set if pictures upload correctly. The truck appears to be built first class. It starts right up without any undue cranking and without clouds of smoke.

Once I get the clutch master cylinder I'll see if it actually moves.

Again I thank you all on this forum. The wealth of knowledge here is very impressive!
