TR4/4A TR2-4A Water Pump Housing

[CinneaghTR]

What do you guys think of the aluminum alloy TR2-4A water pump housings offered by Moss? Anybody have one on their car?

If you are into racing your TR and you want to save a pound or two, it will only cost you about $100.00 to $200.00 per pound saved. WOW ! I wonder how much faster your TR will accelerate if you remove a pound or two of cast iron ???

I'm of the opinion a properly refurb'd cast iron pump would outlast that alloy one.

Yeah, I could only find one car on the net that had one and it was a fast road car. There are plenty of other things I need to do first to make the 4A roll easier than worrying about a couple of pounds at the moment. I am more into stock anyway, but my original pump housing had cracked and I wondered if the aluminum alloy would hold up better in the long run. I decided to spend the extra money on a rebuilt original TR water pump, but I am thinking that my money would be better spent on refurbishing an original housing.

That leads to my next question: What is the best way to refurb the cast iron water pump housing?

I am thinking about taking my replacement to a radiator shop and having it boiled, clean up any major pitting on the hose necks, and then spraying the outside black like the engine. Where can I find the correct thread chaser for the heater line adapter?

Thanks guys,
Jeremy

If the cast iron pump housing has no cracks, I'd go for that option. In 1987, I degreased mine during the restoration in white spirits (Varsol we call it here - or paint thinner) then had it sandblasted with everything else, then it was spray painted by the paint shop with all the other parts - all side by side like laundry on a clothes-line. After 19 summers of driving and 102,000 miles on my 1958 TR3A, the same water pump casing plus everything else still looks pristine clean.

The photo of the engine bay of my 1958 TR3A was taken on concours day at VTR in Valley Forge in 2007. I was awarded 2nd in the early TR3A class with 384 points out of 400 (that's 96 points - the usual way). There were 8 competing in my judged concours class.
