  1. Got a quick job out of the way, removed and straightened the headlight guard. With a combination of the press and a big hammer it was straightened And got it to here And with a bit more tweaking in the vice it's almost as good as new Just needs stripping in the sand blasting cabinet, a spot of weld where the metal has cracked at one of the bolt holes and a coat of paint. One more job ticked off the list.
  2. Have made some progress with sorting out the relentless warning buzzer in the cab, No. 4 air warning would not go out even though the gauge was right up and the cab lock warning was on constantly. I bridged each of the pressure switches in turn with a length of wire until I located No. 4 and removed the pressure switch. They are good old fashioned things that, unlike modern equivalents, can be dismantled and serviced. I took one of my donor spares apart first just to see what was what. Very simple inside, a rubber seal/piston pushes against a spring to break the circuit. The p
  3. Yes it's really simple when you realise how it works. It's beautifully made brass or bronze, I'm not sure if I should paint it or get the brasso out.
  4. Just checked my pics of another and it's the same typo. Obviously didn't have a proof reader at Foden!
  5. I suspect they were wired and piped identically so they could be a tractor or limber on the production line. I don't think they used the same name twice! The handbook, chassis plate and body plate all use different wording. Should have just given it a simple name Also they uprated the front axle from the commercial motor article which stated an 8t front axle where all those I've seen have had 10t axles. Or the commercial motor article got it wrong. Does anyone know how many still survive in the UK in original spec? tractors and limbers. They seem to have
  6. Thanks for the info, an interesting read. Always thought it was a shame they never gave them a proper name. Especially after the matador's, militant's and martian's. Makes you wonder what they might have been called? Was talking to a DVSA inspector today, after an MOT, and I'll need to go to an old fashioned test station for an IVA. This will get it onto the DVSA system and then I can book a regular HGV MOT so it can be registered and taxed. Will confirm this once I have called them.
  7. It was a good call Richard and definitely saved some time. Half the battle is working out how it should work before you can understand how to fix it. I've spent a fair bit of time on a customers Bedford MW and the much newer Pinzgauer. It's nice to have something of my own to work on. I've also noticed there are some extra air pipes fitted which are not connected but tied up along the chassis. I think they are for the winch pto and brake. I don't know if all the Foden fh70 limber's had these fitted or if mine was nearly a gun tractor? I don't remember seeing spare pipes on the last one I
  8. Committed to resolving the diaphragm issue in the gearbox today which I have been putting off for a few weeks. Drained the oil and got back underneath, spanner in hand, for the tedious job of undoing bolts a fraction of a turn at a time through the letterbox. Getting quite swift at it the second time. This time I removed all the bits behind the diaphragm to see what was what. Then realised it's the clutch brake. Had been wondering what the diaphragm was for! Cleaned everything again, found nothing amiss, but realised if this is the clutch brake why does it have a prmanant
  9. After a look at the pipes to the screen wash I realised that I was looking at the pump the wrong way. It's not a pump in the conventional sense more of a pressure pot giving a single squirt to the screen. Fluid enters via either of the top pipes, it's irrelivent which way round the pipes go as the second is just a breather back to the bottle. The centre pipe at the bottom is the air feed, the ball bearing in the fitting stops fluid running back into the air pipe. When air is applied to the centre pipe the small piston is forced up closing off both the top pipes and air then leaks around t
  10. This afternoon I decided to attack the screen washer pump, it's operated by compressed air as I haven't encountered one of these before I have some questions. The underseal encrusted pump is from my Foden and the other is from the donor cab. The donor has already been rebuilt at some point but is missing a ball bearing non return valve. Both were stripped to sort the best parts. As you can see the top housing has suffered from freezing. So it was taken to the adjusting machine... Or 50t press as it's otherwise known. A little over kill but allows a controlled p
  11. Hi to those that have not seen my introduction, this will be the blog of my Foden FH70 refurbishment and restoration. I say that as to start with it will be a refurbishment to get it through an mot, road registered and out in to the wild and then it will become more of a rolling restoration job to get it back to a sound condition to last another 40 years. I got a little carried away and my introduction page has the start of this story so you might want to have a look at that bit.... ....and now your up to speed I'll continue. The exhaust had a bit of a blow So a new s
  12. The weather wasn't conducive to working through the letterbox to examine the diaphragm issue today so I set about some of the odd jobs. First was to refit the front panel stay so it can be opened and closed properly without the aid of a broom. And to get all the lights working. The head light switch was swapped for one from the donor cab, which I had already liberated, cleaned and tested. Just a matter of unscrewing the dash, hanging the old switch out the way, fitting the new switch and swapping the wires one by one. Then went through all the other switches with some contact cleane
  13. I'm hoping the plate can be popped out via the letterbox and isn't captive behind the bearing cover. Otherwise it will be time to remove the body and the gearbox, which will not be so much fun. Will find out at the weekend. If anyone has any pictures of a gun tractor or owns one I would like some detailed info on how the winch is plumbed in to the hydraulics. I have all the main components but am missing some of the pipes and connections. I would like it to look as original as possible. Any info much appreciated.
  14. Quick update, things didn't quite go to plan with the gearbox diaphragm. Filled the gearbox with oil and started the truck, air built up nicely no leaks from the box. After about ten minutes there is a squeaking noise, at first thought the release bearing needed some grease then the air pressure drops and the dreaded hiss from the gearbox starts again. It turns out that the plate the diaphragm presses on is turning with the layshaft and was rubbing through. I've yet to investigate as to why. Hopefully it's just jammed up with the old diaphragms. On the plus side I now have a full set of
  15. Thank you Paul I'll get in touch and see what info he has.
