Waterpumps: A word of warning...

[alun n]

...to those of you with long term laid up slant 4's.<br>
<br>
This pump is knackered:<br>
<br>
<!--EZCODE IMAGE START--><img src="http://im1.shutterfly.com/procserv/47b6 ... btWjlsxZMS" style="border:0;"/><!--EZCODE IMAGE END--><br>
<br>
awaiting rebuild, nothing really amiss there.<br>
<br>
This pump:<br>

is the worst I have ever seen and came out of a car that has been laid up (and started regularly, run to temperature) by the PO for the last 12 years! It was so badly corroded I thought I wasn't going to get it out; I made an improvised slide hammer using a jack handle and a 10kg weight - the jack handle straightened!<br>
<br>
Note the brass cage has its holes full of solid iron oxide which had corroded to the block!<br>
<br>
The impellar crumbled in my hand and the vanes disintegrated.<br>
<br>
Most of the oil thrower disc has disappeared.<br>
<br>
<br>
<br>
I think I'll be running it on a couple of fills of flushing oil!

I reckon it will need a new seal at least <!--EZCODE EMOTICON START :rollin --><img src=http://www.ezboard.com/images/emoticons/roll.gif ALT=":rollin"><!--EZCODE EMOTICON END--> <br>

...I just yanked the original factory fitted water pump out of my 1973 Stag. The car had not run in 14 years. But the previous owner had drained the cooling system. The pump came out, cage and all, extremely easily. It was not corroded, but the seal had perished. There was no rust or schmootz to be seen anywhere on the pump.<br>
<br>
And speaking of pumps, the latest ones now come from India. There are available here in the USA new for $99. They look a quality piece.<br>

China eh? I wouldn't touch them.<br>
<br>
Some remanufactured ones were made in UK a few years back and weren't properly hardened; result was the skew gear on both the pump and jackshaft wears out. Wherever possible I will use a repair kit on the existing shaft; Brian Kitley even goes as far to use the matching pump and jackshaft together wherever possible because of the mutual wear patterns they create.<br>
<br>
On the other hand I have met TR7 owners who believe in changing the whole pump every 12k as a service item...which is why there are few original pumps left!<br>
<br>
China; do a good job of copying something cheaper. As I say to myprospective Clients when they try to get a lowered fee proposal out of me: 'Which bit do you not want me to do?'

Indian stuff seems to be not that bad. They do a fairly good job of 50 year old Morrises, after all...<!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"><!--EZCODE EMOTICON END-->

...has anyone had trouble getting the top seal from a Fitchett's kit to sit within the brass cage? The one I have is slightly too big for all the cages I have to hand...<!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/images/emoticons/frown.gif ALT=":("><!--EZCODE EMOTICON END-->

I had the same problem with one from robsport. Think i used a two or three leg bearing puller somehow. Cant remember how exactly. Went in eventually. Very tight though.

...Hart Racing Services are currently advertising a kit with the metal spring cup on ebay; I asked the question about it being too big and he replied it is a tight fit and normally has to be fitted using a press.<br>
<br>
If I were to press mine on firstly it would likely distort, secondly I doubt I'd ever get it off again. Not a problem until the pump goes next time; think of the scenario, cage won't let go of the block, spring cup won't let go of the cage. I wonder if anyone involved with the manufacture has considered how to get it out again at that point...?

I was helping somebody fit a Sprint engine in a TR7 on Saturday and we were gonna overhaul the water pump. The bolts came out and it wouldn't budge so we put the bolts back in and he's gonna chance it when he gets it running. The job will be a bit harder with the manifold and carbs back on! I'd read this thread earlier on and doing the job reminded me of it.
