1963 3-speed speedometer gears

Hello,

I am not having any luck locating the speedo drive gear for a 1963 3-speed manual trans. Trans code is C3AR-7006-E. Speedometer cable is on the driver's side.

I tried a couple of places online and local parts stores, no luck.

Anyone know where to purchase new speedometer gears for this transmission? Any guesses on tooth count with 3.90 rear axle and 235/75/15 tires?

Thanks!
Brian

I talked to these guys today:

Ford Speedometer Gears for Automatic and Standard Transmission

He said they have the drive gear for a 1964 transmission, but it will not work in a 1963 transmission. Mentioned there was a major change from 63 to 64. From what I have found, I thought the major change happened between 62 and 63. Maybe there was a major change both years?

BS!

Mentioned there was a major change from 63 to 64.
Uh huh,
What's the difference between a 1963 vs a 1964 F100/250 3 speed manual? NONE!

Same Ford type 3.03 all syncromesh introduced in 1963.

9" rear axle ratio should be 3.89-1, not 3.90.

Speedo DRIVEN gear (end of cable) could be nylon or steel w/a fiber gear riveted to steel body.

DRIVE gear on output shaft could be nylon or steel. Correct gears depend on trans type/rear axle ratio/tire size.

Parts catalog does not list P-metric tires sizes, so you'll have to convert the 235/75/15 to the original bias ply size if you want correct Ford part numbers.

Or, count the number of teeth on these gears, tell me what they're made of.

btw: The 16 thru 21T nylon DRIVEN gears have been used for over 50 years. ALL are available from Ford for less than 5 bucks each.

Thanks for the confirmation.

I think I will take the gear out of the trans so I can give them the measurements. He is telling me the ID on the drive gear is different in a 63 trans vs. a 64 trans.

Thanks again.

"He" hasn't a clue!
1963 F100 2WD 3.89-1 15" wheels DRIVE gear most likely has 6T and is D0TZ-17285-A (replaced B7C-17285-A).

D0TZ-17285-A applications: 1957/62 F100/250 with Ford 3 M/T non syncro 1st gear / 1963/86 F100/250 with Ford type 3.03 all syncro M/T.

Also used with 3 O/D, 4 speeds and A/T's on myriad other F100/350 ratios/applications.

Just want to make sure - Did you mean DRIVE gear?

Typo: DRIVE gear is what I meant (since corrected).

You won't find a 6T driven gear, that's for damn sure!

Since all these gears are available from Ford, where do you think these repro parts sellers are buying them from?

CODZ-17271-A has an MSRP of $5.00. If bought from an FTE Ford Dealer Parts Dept sponsor, the price is even less.

tousleyfordparts.com price: $3.30 / Tousley Ford ~ White Bear Lake MN

silverstatefordparts.com price: $3.54 / Gaudin Ford ~ Las Vegas NV

horizonpartsguy.com price: $3.60 / Horizon Ford ~ Seattle WA

You have to pay shipping charges, but you do not have to pay double the MSRP!

I agree, but I needed several other items from DC so the shipping was sort of free on the speedo gear which some what made up for the over charge.

This is an old thread, but I finally had a chance to remove the speedo gears.

Bill - Do you have a way to verify the gear part number you referenced is in fact this gear:



I cannot find anyone who sells it that has a picture wit hthe description.

Thanks!

ID is very close to 1.375" (don't have my calipers here at home, so I had to use a tape measure).



Thanks!

Thanks. Just trying to verify, since I do not know if the truck has the original transmission.
