Thread: Diggers '52 80"

Digger, don't even attempt to remove the top part of the thermostat housing unless you know for a fact that the thermostat is US. The outlet pipe housing (see below) is attached to a "box" like (part #263670) and this housing is fixed to the front of the head by 3 long and one short studs. Remove this housing complete with the outlet pipe and inlet pipe bits still fitted. The whole housing assembly merely sits on top of a rubbery washer and copper tube to the water pump.
The actual thermostat outlet pipe housing itself is a rather delicate piece of equipment made out of a reasonably soft aluminium foil-like material and prising it out with a screwdriver or the likes of such can do irreparable damage.


I have just spent a couple of days re furbishing my thermostat housing using a "dremmel" and some "quik-steel", (an epoxy two pack synthetic metal mix available from most car outlets- similar products have different names) to rebuild the eroded away shelf upon which the actual thermostat sits inside the housing, and also had an acquaintance from the MJCQ turn me up a new outlet pipe section as per the photo below.


Take note that the seal around the thermostat is actually between the internal "shelf" inside the housing, the thermostat itself and the bottom of the collar of the outlet pipe housing, not between the outlet pipe housing and the thermostat housing.
There are only the three openings to this housing, the small inlet hole from the water pump itself at the bottom, and the two inlet/outlet pipes unless your was fitted with a heater. There are two other outlets but both of mine are blanked off. The face that is sitting against the front of the head, even though there is an outlet from the head itself, is sealed off and does not allow water ingress.
Hope that this of some use to you.
Regards
Glen

Cheers guys!


More questions..

I also need the metal flexible tube the wiring travels in up to the windscreen...
**do they still make it?
**If not, where would anyone suggest I look for some?

Now while I'm at it, I have a pair of nos (still in wax paper sealed boxes) trafficators, I want to put them on the windscreen BUT also run a set of led blinkers front and back...

I need 12V CONSTANT to trafficators
I need 12V to flasher can so alternating power to operate LED front and back(eg blink)

My question is this...

can it be done off the one switch? (i think so)

I assume two sets of wires from blinker arm 'blade"(instead of the usual one), that being 1 to trafficators , and another to flasher can and onwards, BUT will this:-

** overload the switch?
thinking standard (replica with hazards switch) magnatec style indicator arm OR (I prefer) bakelite (old style) switch in centre of windscreen..

**So, if going via bakelite switch how can I get front and rear LEDs to flash as hazards? (I assume another switch...?)

Interested in wiring designs - step by step if needed!!
But set out for a pinhead like myself to understand please...

Photos if someone has done it?

The trafficators are held open and lit by the constant power they cannot have too much variation as I understand it as they'll close/open/close open etc etc until buggered!!

I hope thats clear.... (probably like mud! )
ask if there is more info needed...
Cheers

Hi Digger

To get the wiring size right use this guide.

to divert the current away from the switch, a couple of automotive relays can be wired to operate the trafficators with the indicator switch.

Important! always use a fuse at the point where any power is picked up from.

These are the units destined for the wings, L489 lenses I think, with L488 double filament bulb holders.

There are cast-iron water pumps available on Ebay, which don't fit perfectly and require a bit of grinding and a thread change - quite cheap though and better than a corroded one,

Cheers Charlie

how much are the cast iron ones i have seen some on there for $150 and some for $230

Last one I bought was from the 4wd mob in Vic. $175. One hole needed opening with afile but its still working OK. No complaints yet.
