HUP project started at last

[Alex van de Wetering]

Lovely work Jonathan....and thanks for keeping us updated. Great to see the C8a coming back to life, after loosing it's body so long ago.

regards,

Alex

Sorry, I didn't take pictures of that. There is a picture in the workshop manual but I have a new laptop with windows 10 and I am buggered if I can work out how to get the bloody printer to scan. What was wrong with windows 8.

How about the brakecilinders where did you dig those up...
also question on the central wheel nut what kind of wrench do you use to fix the nut ? I'm looking for a wrenchcap(?) don't know the English word to fit the 70mm wide nut (its quite big)

[Jonathan Moore]

Here you go, if you have problem, I will get the link off ebay. In my opinion the front brake pipe, chassis to axle, could do with being a bit shorter. I couldn't find a socket to fit the large nuts, so I made a very crude one to suit. It works a lot better than a hammer and chisel, which is what had been used in the past by previous mechanics.

All of the parts that I have been waiting for have turned up so I was able to get the rear axle in and the brakes installed. It took quite a lot of searching to find some of the components so I will post where the parts came from.

Rear brake cylinders - Ebay (usa)
Drum Brake Wheel Cylinder-Professional Grade Front Raybestos WC3406( 161726933472 )

Rear spring u bolts and long nuts - ATS springs www.ATSsprings.com (USA) 9/16X3-5/8X9-1/2\" ROUND U BOLT KIT x 2 sets

Front brake cylinders - Ebay (usa)
Drum Brake Wheel Cylinder Dorman W4571 fits 40-47 Ford 1 Ton Pickup( 281439639223 )

I had time on Sunday to pipe the brakes in. The brake hoses that were on the vehicle, were far too long, infact, the front axle to swivel housing hoses, rubbed on the inside of the wheels. After a bit of research I found a company in Southhampton Hampshire, that had the correct hoses, run by a very helpful chap called Steve.

STAR Automotive

Front axle to Swivel housing - NAPA part Number 4900 or his invoice UP4900
Front and rear chassis to axle - NAPA part Number 4960 or his invoice UP4960

I hope that helps.

Your efforts to rebuild the HUP are extraordinary and the preservation of a less common vehicle is to be commended. Could you please post some pictures of the profile the of the re-enforcing channels that support the roof.

Gord

[Jonathan Moore]

Thanks Gordon, very nice of you to say so. I hope that these are ok, obviously deeper sections in the rear and shallower in the front. The worst parts to form, were the radius sections, I tried several methods and in the end made some rollers for a pipe bender. Unfortunately it deformed the centre slightly but it was the best that I could do without press tools.

Regards,

Jonathan

[Gordon Yeo]

Jonathan

Thank you for the pictures. Great work and will watch your progress with great interest.

Johnathan,

How much overlap does your hatch have versus the hole in the roof?

Seems I messed up my measurements..

I've been busy, the roof is finished, apart from a bit of grinding. The rear sun roof took me longer than expected, it never ceases to amaze me how long making all the little bits takes. It now locks, lifts and moves as it should. The front passengers observation hatch is in place and for once this contains some original parts. The inner and outer frames were actually present and usable, as were the hatch catch and strengthening ribs. Alas the actual hatch is long gone and the fabricated replacement was rubbish so a new one had to be made.

Obviously and as usual, the only firm information that I have to work with is from the few dimensions and pictures supplied by Robert. As I don't have any original parts to copy this information has proved invaluable. The next job, is the rear wheel arches and guards. As I finish off grinding the roof, my mind has gone on to how to form the guards. Well It gives me something to dream about at night.

Regards,

Jonathan

Looks fantastic Jonathan, only wished I was at this stage....

Jonathan,
Did you make the actual omegaprofile or did you bend square tube?

[Jonathan Moore]

Hi Pieter,

The hatch size is 51 1/8" x 39 1/8"
The hole is 37 3/4" x 49 3/4"

I made the profiles and then bent them, I tried several methods and that was the best that I could come up with. As you know its a labour of love and HOPEFULLY mine is nearing completion ready for me to start the next one,
ha ha.

Progress has been a bit slow but its coming. I have been working on the wiring, which is complete and working now. Its all done with cotton covered wire and to the wiring diagram but I have added a fuse box. The horrible bit of modern wiring, that will be hidden under the steering wheel, is a 12v-6v transformer for the horn. I have connected it with blue connectors so that I can't get the 6v and 12v systems mixed up in the future.

I don't see the mounting of the coil, do you have the coil on the engine.?
My version has a special mounting tray mounted near the rear of the dash..

[Jonathan Moore]

I have bolted my coil to the engine, as it was when I got it but when I was preparing the body for spraying, I found the remains of the coil brackets above the engine on the body frame. To be honest, I am not sure if these brackets were only on an HUW or whether all early C8's had them. Roberts, which is a HUW shown below has the same brackets.

Yes I have these brackets to mine is a HUM did not know that there is also a lid for the tray, I only have the bottom part of the tray.
The tray makes sense though for easy access...

[Phil Waterman]

Hi

Be careful of the coil bolt length the hole go all the way through into the valve push rod passage. Seen two problems, 1st actually hitting the push rod, 2nd oil leaking around the threads of the bolt.

Keep up the great detailed work.

Cheers Phil

[Jonathan Moore]

Thanks for the information Phil I will check the bolt length.

Jon, the position for the coil was unique to wireless trucks (and maybe machinery vans?) for radio interference suppression. If you had a moment, I'd love to get some details and measurements on the coil cover as I have to make one for my project.

[David Dunlop]

Pieter.

By 1944, that radio suppression coil mounting up under the hood framework was standard issue for all Chev C15A Wireless Trucks and Chev was also producing a conversion kit that enabled retrofitting this equipment to any Chev that was deemed needed it. I think I posted the instructions for the kit somewhere on the Forum a while back but cannot remember where.

Levy's in Toronto used to sell the complete kits.

Thanks for the info,...any contact data on Levy's ?

Unfortunately they closed down and the site was developed into condos over 30 years ago. But that's another story in itself.

[Jonathan Moore]

Progress to date. All the fiddley bits take so long.

[Alex van de Wetering]

Awesome work Jonathan! Great to see the truck back as a HUP again.

Alex

[Gordon Yeo]

Jonathan

A big undertaking and congratulations on a job well done. Lovely to see anther HUP come back to life and rejoin the CMP fleet.

Gordon.

[Hanno Spoelstra]

Amazing job, I am awe inspired seeing how you transformed this "bitsa" - or more accurately: "cut 'n shut"- back into its former glory

[Jonathan Moore]

Thank you all for your kind comments, I am looking forward to getting him on the road and attending some shows next year.

Jonathan
