Identification of F15 2WD?

[Ganmain Tony]

How about this to throw a spanner in the works.

Cable is 43 and 1/2 inches long.

Outer conduit is 33 inches long.

Interesting to note the outer conduit length is identical to the old ones I pulled out.

The inner cable appears to be slightly longer though on the old cables. It is a bit difficult to tell because both cables had snapped at the end that attaches to the equalizer arms.

Hi Tony,

That sure does- throw a spanner in the works that is.
With your conduits being 6-3/4" shorter than mine it must be a bit of a stretch between the backing plates and the conduit supports.

I enclosed photos of original handbrake cable routing on my F15-A parts truck. There is reasonable amount of slack to allow for suspension movement. I am certain the crossmember where the equalizer is fitted is in the same position on both F15 and F15-A trucks so the distances to the backing plates should be identical. I know this the hard way- In my earlier naïve days I bought a dodgied up F15-A that had been converted from an F15.

The other surprise is look what I found! A handbrake cable to spring bracket had slipped down to the backing plate. I've had the truck 3 months but hadn't seen it. Of interest is that it seems to be of thinner gauge steel which may be as Grant Bowker pointed out in an earlier post there was a C01Q 2279A bracket and a later replacement C01Q 2279B.
I used a bracket remnant attached to a spring of a 1944 built truck to get the thickness. This thinner bracket is on a 1943 built truck. Perhaps they found in service the thinner gauge one broke early from fatigue and reissued the part in a thicker gauge steel hence the A and B versions.

Cheers

Slight correction:

Yesterday I removed the brake cable bracket remnant of the end attached to the 1943 truck spring and I notice it was folded over doubling the thickness. I looked more closely again at the 1944 remnant and it too had been folded at the spring end and therefore that bracket was the same thickness as the 1943 bracket.

On that basis anyone recreating this bracket could make it from 16 gauge steel with the length of the fold over exactly 1". I can also confirm the spring bolt hole is 13/32" diameter and the clamp bolt hole is 9/32" diameter. the center of the spring bolt hole is 1/2" from the end and the center of the clamp bolt hole is 3/8" from the end. the flat end at the clamp area is 3/4" long. With Tony's 3-1/4" BC of the holes and 3/4" wide steel that should be enough info for anyone to replicate it.

This means my suggestion that there was a thickness difference between the A and B part is not necessarily correct so whatever is the difference is still yet to be determined.

Cheers

Looking closely, you are spot on Jacques. If I attempt to shorten the conduit, odd's are Im going to hit the inner cable. Plus I am only going to get another inch or so and that aint going to be enough.

The NOS cables Ive got cant be the right ones. Be interesting to know what they are off. Must be some thing from the era.

If anyone does have some I would be interested to hear from you.

Have looked up MACs. They have a 46 inch cable 21C 2275. Im going to give them a go.

[Grant Bowker]

I suggest caution on the Mac's cable. Nothing against Mac's, I do buy parts from them.
It's the part number structure that makes me nervous. 2275 is a generic part number for brake cables of the era and the prefix C01T, 21, C01Q, C101W etc. define the year and model the part was first used on. An example of a long-lived part number is BB5783 (rear spring bumper used on F15A). The BB indicates it started being used on the BB trucks ~1932, well before CMPs existed and I've often seen them advertised on ebay as being for P series panel vans of the 1970s (no mention of earlier uses). 21T indicates 1942 truck. 21C 1942 pickup.
I would expect the 21C-2275 cable to be for a 1942 pickup truck. It might fit your application perfectly, be close enough or be significantly off. Just speculating now but it is also possible that parts developed in Canada and later adopted for US use were renumbered to avoid having the C prefix in the US system - I don't remember seeing it in US parts catalogs

Noted Grant,

I realise I'm being a bit of Guinea Pig here. But I'll give it a go and 'take one for the team".

Hi Tony,

Yes I know the feeling o being a guinea pig. Usually after weeks of searching and fruitless enquires and buying something not quite correct someone says to me have you tried "Joe Blogs" he has dozens of them!

I have two ideas which may be of help:

You may have heard of Flexible Drive here in Melbourne. They make control cables for all types of applications. I have never dealt with them but perhaps they could be of assistance to make up new ones to the required dimensions. Just Google their website. Has any MLU members had any experience with them?

The other thing is Dirk Leegwatter had cables with Part No. C01Q 2275B which were 86" long on the inner cable but the conduit was about the same length of 40-1/2" as the F15/F15-A cables. If the inner cable could be shortened you could have the handbrake cables you need if you cannot find the correct F15 ones.

Does anyone know hot the ball end of those cables are secured to the cable? Spot welded?, Brazed?

Food for thought anyway.

Cheers,

[Grant Bowker]

The ball ends are swaged to the cable.
The process is described at https://www.youtube.com/watch?v=hp0skdRW_TI
The machines are made by https://loosnaples.com/swaging-machi...oloc-m1-type-i and are not cheap!
My experience when getting C01Q 2275B cables shortened to closely resemble C01Q 2275A cables was that there are limited service providers, but they do exist. One source is through Aircraft Spruce https://www.aircraftspruce.ca/catalo.../cableassy.php You will be asking them to swage a SA110-5 ball onto a customer supplied cable assembly after shortening the cable. The wire cable is 5/32" 1x19 stranding. They prefer to cut the cable in order to ensure against damage in shipping. I believe the actual work is performed by ACS Products http://acsproducts.co/ It ended up costing me nearly C$150 to shorten the 2 cables (including shipping both ways, about 50% of the total) - not cheap, but a bargain compared to the machinery to do it myself.
