3. From memory (not to be trusted 100%) I think Clark Brothers Instruments http://www.clarkbrothers.net/catalogs.html had similar tips but not absolutely identical to Chevrolet. My memory is that the precise cable and sheath weren't obviously available but I may not have looked hard enough....



A couple of days ago I made up a dummy to see whether the sheet metal guide at the transfer case could be replicated on a bead roller. No photos at this time but the summary is "exact to the nth degree" - no, but functional should be possible.

Hi Grant,

I had a look at Phil's drawing and my dimensions are the same where it connects to the driven gear: tip diameter = 0.203", height of tang = 0.040"
Overall length is different. Mine is shorter at 1.20" (nominal 1-3/16" same as Clark Bros tip J-2) Likewise my shoulder position is the same as J-2, 3/4".
There is also no O-ring notch on mine or tip J-2.
My shoulderless tip has the same tip diameter and tang height.
Both tips were pulled out of Ford transfer cases that looked like they hadn't been touched since WW2. It has just dawned on me. I think the J-2 type came from a two speed transfer case and I think it had a large diameter casing. I replaced my 2 speed with the single speed in keeping with a F-15A. The shoulderless type definitely came out of a single speed case and had a remnant or 1/4" diameter casing on the ferule.

The only bare steel outer casing Clark Brothers stock is bulk 0.25" OD which is the Ford commercial and F-15, F-15A size. Perhaps Ford used a larger casing on their two speed transfer cases too?
Covered sizes may be the same as Chev, without the covering, but I will leave that to the Chev guys to determine.

Good Day.

Further to previous post and to keep it short:

Does anyone have the Ford F60L-01 Spare Parts list?

It would be interesting to see if the part numbers were the same for the speedometer casing and shaft of the F-15A and F-60L as fitted to new design cabs.

For the F-15A:

*C29Q 17261- Casing Speedometer shaft. Used with new design cab
*C29Q 17262- Shaft Speedometer. Used with new design cab

I would think the lengths would be similar based on location of driven gear.
If different part numbers, it might explain a larger diameter casing on a two speed transfer case.

F60L-01 parts list

Hi Jacques,

The F60L-01 parts list Dec 1942 issue shows:

C01Q 17261 Casing speedometer - used to serial #21565 with old design cab
C29Q 17261 Casing speedometer shaft - used from serial #21566 with new design cab.
106749 - key, speedometer drive gear (74142-S)

C01Q 17262 shaft, speedometer, used to serial #21565 with old design cab
C29Q 17262 shaft, speedometer - used from serial #21566 with new design cab.

*083065: Sleeve speedometer drive gear (C01Q-17269
* 1809553: Gear speedometer driven - 14 teeth (C01Q-17271-D)
*284414: Bushing - speedometer driven gear (C01Q-17277)
*1809534: Gear-speedometer driving - 4 teeth (C01Q-17285)
C01Q-17288 Spacer, speedometer gear.

Hope that helps. - Edit: looks like I was typing while GJ was scanning!

Hi Graeme and Mike,

Thanks for your replies. Based on those same numbers, Ford single and two speed transfer cases used the same speedometer casings and shafts on the Cab 13's. Hanno's speedometer shaft would slot right into a F-60L casing.

Only the following are different:
Driving gear, C01Q-17285-A (4 teeth) Note: this is also listed as part 1809534 same as the F-60L part number. "A"?
Driven gear, C011WQ-17271 (15 teeth)

The key, sleeve, bushing, and spacer are the same part numbers as the single speed case.

Thank heaven I keep a box of "samples". Since posting the previous posts I found the ferule and remnant of the casing from what I believe was the two speed transfer case.
It measured 0.452" in diameter which would be nominally 7/16"
This does not prove anything, however, as the transfer case was installed in the modified F-15A chassis so the casing could have come from anywhere. Different supplier or even a Chevy perhaps? Bush engineers grab whatever is laying around.
I am fairly certain the transfer case had Ford markings on it but it is long gone to check.

This could be helpful, there's a clip on the underside of the engine cover clip mount, and another higher up in this pic from the F60S assembly guide. It's from a pdf uploaded to my facebook group by Mariano Paz.

Thanks Keith, that image confirms the routing of the cable alongside the engine. I now know the cable on my F15A needs some clips to secure it.

Re. Mariano’s file, it is on the MLU Forum FB group also and I have shared it on the Forum here as well: http://www.mapleleafup.net/forums/sh...ad.php?t=31370

Hi Keith and Hanno,

That is great information again! Would not be surprised if the clips used to hold the handbrake cables at the rear springs are not the same and just repurposed.
It may also account for the hole on the frame of the floor.

I will still climb over paddock relics, just the same!

Cheers,
