Hello Bill

Looks like you have a nice project there to keep you busy, dont wish the winter months on us to soon, I have lots to do. Whats your plans for the Bolster, will she stay as is or will you convert her to something else. You can get reprint manuals on Ebay about £21. Just type in GMC CCKW Manual. good luck with the project are be watching! Howard.

Thanks Howard! Sorry for wishing them

Thanks baz will have a look :-)

If you have any problems with that give me a nudge and I can e-mail you a copy

thanks baz, I would really apeciate it if you could! ill pm you my email.

weathers really shocking down here so haven't been to the yard today, so hopefully I can get there Wednesday and get some more detailed photos of her, really looking forward on starting!.

ps, ill try and get the photos to come out more straight next time!!.

Gave the jimmy a power wash, get all the moss and grease etc, gave her a little drive around the yard,

engine is very very sweet! She's had a new clutch fitted by previous owner, soon to start restoration! Bill.

I'll be looking for the a picture of the pioneer rack with all the tools attached. And would love a few photos of the Jimmy bolster trucks in the war etc, any pictures greatly appreciated!

fitted a new brake pipe of which the last one corroded and burst, all the other pipes look fine and new, whilst bleeding the brakes, once the brake pedel was touched the engine would make a different noise (I no they always do a little) and then smoke would come out the inlet manifold, but when the brake pedel was let of the noise and smoke stopped.

somehow I think brake fluid is getting up into the inlet manifold, going to check the hydrovac, if that's ok what else could it be?, regards bill.

Hi Bill,

Sounds like the hydraulic cylinder on the hydrovac is leaking in to the vacuum cylinder and hence being drawn into the engine. You will have to inspect the cylinder, and overhaul or replace.

Thanks rich!

spoke to Howard about this- check the drain plug on the vac tank etc so that's tomorrow's job :-)

Un-done the drain plug on the hydrovac & out poured Blake fluid, time to come of.

hi all, took the hydrovac of as that's the problem, now all I need is a new one or for it to be rebuilt, would anyone no were to go for this? or have one, I do have one option but im keeping it open.

& would anyone no what sort of mudgards the pontoon trailer would have had??.

bill.

Rex Ward is the man to contact for your hydrovac repair, http://www.dukwparts.com or tel 01189 306300.

If you put GMC Pontoon trucks in to your search engine you will find pics there that show the mudguards.

Thanks mate

After inspection the manifold had a crack down the side, all of and instead of buying anther we welded her up.

Hello Bill

Just a tip get a straight edge and run accross the manifold ports from edge to edge with the intake manifold bolted up, make sure all the ports are flush, if they are not all flush then it would pay you to get it machined level. also if this is done find out what they take off, your need to reduce the depth of the 3 seating rings for the manifold, other wise when you come to nip it up the manifold it wont do up as tight as it should, it will stop on the rings and not the gasket. Hope this helps Howard.

Thanks howard will bare that in mind.

Once done I'm thinking of building an authentic crate to sit on her & the trailer possible to sleep in for the shows etc.

Need some help with the breaks.

bled the breaks a few weaks ago, went to pull away and they was jamming on, ovbiously thought they were sticking but once the engine is switched of she rolls freely, which must lead to the hydrovac, some folks said the master cylinder but if the master cylinder was faulty it wouldent leave symptoms like that, it's asif the hydrovacs staying on as soon as the engines switched on, anyone had these problams, any info would be greatly appreciated.

No free play in the pedal, piston can't come right back so brakes come on with servo.

You need one inch of free travel at the pedal with engine off, and it should stay there when the engine is running. If you have free play it might be the piston not returning fully anyway.

Yes there's three play in the peddle, it's quite baffled me if I'm honest, it's a basic set up the vacs been rebuilt but as I was building pressure up whilst bleeding the breaks, I built pressure for quite a while, I'm abit worried I made a valve inside the vac stick, hence when running they come straight on?.
