Thread: Ex-Military 109 GS (202)

Figured out why the feed from the brake reservoir had a piece of hose joining a steel pipe at each end. It's a later CV master cylinder and it has metric fittings !

Made up a new brake pipe from the junction on the chassis up to the master cylinder and the tube nut was too small. Hunted down the pipe I took out when removing the booster and found that a short piece of pipe with a metric tube nut had been brazed to the end of an imperial pipe (tube nut still in situ).
I'll have to take a picture of it, classic bit of bush engineering when a suitable flaring tool wasn't available.......

Just found a picture of it in situ, post #6, last picture. You can see a tube nut on the tube above a tube nut screwed into the master cylinder.

Couldn't get it started today, ran for a short while if you tipped petrol down the carby.
Turned out thet the fuel in the float bowl had evaporated and it takes some time for fuel to get pumped from the tank (I miss the manual priming lever on a Landy fuel pump).

Changed the tube nut on the brake line so it's now Imperial one end and Metric the other. The brake pipe I sourced was that horrible green painted stuff, my flaring tool tends to damage the paint.

Here is the 'bush' fix. Obviously no access to a flaring tool so a piece of pipe with a metric tube nut was brazed onto the original pipe......

Tried to get it started at the weekend and there are fuel supply problems.
Looks like it either needs a either a fuel pump diaphragm or there is a leak in the fuel line letting air in or maybe a blocked in-line filter.
Fill the float chamber and tip some down the carby and it starts & runs but just will not pump from the tank.

Steve, the owner now has a problem. The vehicle is in Narre Warren and he needs to get it to Springhurst (just past Wangaratta).
His wife has just had another baby, he has a lot of work on and the time to drive down & collect plus the cost of trailer hire mean that he might have to let this one go to a new owner.

I'll put an thread in The AULRO courier service first......

Bad points.
Rotten front crossmember.
Most military bits gone.
Holden 202.
Transfer box needs replacing.
Aircleaner missing.

Good points.
Holden 202 runs well and has a new water pump.
Radiator (series 3 type) looks new but it has been modified to fit.
Good single cab.


If it comes to it I can part it out but I like to try to move it to Steve first, if that fails sell it, parting out will be a last resort.

Had another go at fixing the fuel supply problems.
Fuel pump off, debris cleaned out and seems to work OK. Put it back into the fuel line and it pumped fuel.
Re-fitted it to the 202 motor, filled the float chamber, tipped fuel down the carby and it started & ran OK. Then died when it ran out of fuel.

Still not delivering fuel. Checked and the float needle wasn't jammed so the motor is not operating the pump.
Not being a Holden man, what operates the fuel pump and can the pump be fitted incorrectly ?

Need to get this mobile so I can deliver it.

Hi Colin

From memory (it has been a while since I worked on one of these) the fuel pump simply has a lever that runs off the cam. Same operation as a 2.25 petrol rover engine. It could possibly be the diaphram in the pump. These will go hard with age and split. Once this happens the pump no longer functions.

Cheers, Martin

Yep, just a lever off the Cam. The diaphragm will be split as mentioned. Easiest fix is an electric pump if you have one lying around to get you going.

I have a good pump here I can lend you if you just need to shift it somewhere but it's off an engine I'm selling, so I sort of need it back. I can drop it around either Monday sometime or later in the week.

Thanks for the offer but I have a s/h facet pump I can fit as a temporary fix.

Someone told me yesterday that he thought the cam for the pump was pinned to the camshaft ? If that's the case could the pin have broken ?
Another thought was that the diaphragm, although not split, has taken a 'set' and is holding the lever away from the cam.

It did work for a while then stopped, manually operating the lever it works.


Colin

Sometimes it is possible to miss the cam with the lever, when installing the pump - it sits beneath the cam instead of on top of it.

Rotate the crankshaft by hand, whilst looking into the port with a torch; when the cam is sticking towards you, or towards the bottom of the engine install the pump. I find it handy to lift the lever upwards as I do this, to make sure that it can't slip under the cam-lobe,

Cheers Charlie
