Series III heater tap

[gromit]

A while ago I ordered a heater tap from the UK in amongst some other parts, when it arrived it didn't match the one fitted.
I decided to hunt down a replacement and all I could find was the same one I was supplied from the UK, nothing looked like the one fitted. Checking parts books & manuals the heater fitted to mine didn't even look the same.

Turns out the heater & valve were 'local' items.
In the UK the valve is fitted to the engine and in Australia it's on the side of the heater.

Thanks to Jim at 4 Wheel Drives in Blackburn I found that the valve is from an XW Ford. I found that Rare Spares have them HEATER CONTROL TAP ASSY XR XT XW XY, ZA ZB ZC ZD (http://www.rarespares.net.au/rarespares/ProductPage.aspx?product=HT2001) $79 each. Also found them on Ebay ranging from $166 down to $75.

I also noticed that the heater is shown under 'optional parts' for the UK which is a bit of a surprise.
Also in UK rebuild articles they show rusty heater blower housings but the only ones I've seen here are plastic. Was this a later modification or again a 'local' thing.

A couple of questions :-

Is there a modified parts manual for Australia that will show the part numbers for the heater assembly ?
There's a resistance wire in the heater duct, what does this control ?

Yes.

Whole thing was local manufacture - Ford tap common to 70s Falcon/Fairlane, Smiths fan and plastic cowl, different diameter ducting etc. Even the metal trim on the outside of the mudguard is different.

In the UK we only see metal fan casings, and usually rusted out at the bottom.
The big resistor in the airflow is the slow speed option and the switch is ON/SLOW/FAST. They rarely fail but often fall off. The smiths motors are prone to seizure as the grease dries up but you can regrease the plain bearings if you take them apart. Never seen one with the brushes worn down yet.

The valve you guys have looks similar to our London Taxi heater valve and modern equivalents are available quite cheap at £14

You can get these heater taps from here https://www.americanautos.com.au/secure.html

Code: HT2001

The only thing you will need to do is to rotate it to suit the Landy..

PS:Oops didn't see that you found them at Rare Spares. I bought 2 from them and they fit perfectly..

The resistance wire is used for the FAN high/low speed selection.

Thanks guys, I have added the post/s to the generic SIII parts thread.

There is a list of parts specific to the Australian market at the back of some of the later parts catalogues, but IIRC it doesn't refer them back to the exploded diagrammes.

Hello from Brisbane.

That is the case with the version of the S3 parts manual that I have - it lists the Australian part numbers as an addendum, but they are not shown in the diagrams for the relevant sections.

Apart from the seat belts, heaters and rear number plate frame, there are probably not a lot of significant differences between the UK and locally assembled models? Military variants and the Isuzu diesel models being an exception I guess.

I used the same replacement part when overhauling the heater unit on my SIII
You may find that the Ford valve you get is not oriented the same way as the one in your Landy. Turns out it can be taken apart and re-assembled with a different orientation to match the Landy. They made one tap to suit two different vehicles.
The resistance wire is for a 2-speed heater fan.
