mikeb Posted January 15, 2006 Report Share Posted January 15, 2006 Hi all. I am re building my TR7 engine after having it rebored etc. The water pump came out but it left the brass outer casing in the block. I could see no way of removing it with out damaging it. The main pump spindle assembly showed no signs of wear, so I have replaced all seals and bearing. With the pump fitted back in the brass housing and the top cover off, I find that the jack shaft will only turn using a spanner with out to much force but not by hand. Would this be becouse of the new seals ?. I would liked to have taken the brass housing out to replace the seals but I have been told that they were done about 3 years ago.

DaveH Posted January 16, 2006 Report Share Posted January 16, 2006 Mike Managed to get the brass cage out using a three leg puller, with an old spanner across the bore. A bit of a fiddle but it worked. You can buy a slide hammer to do the business. See main supplier catalogues. I guess it would be sensible to remove the cage and replace the seals-although with only three years use ( probably with low mileage?) there shouldnt be much wear and tear! I used a replacement seals kit and the pump leaked-wished I had bought a replacement pump in the first place!. New pump worked fine.. I think pump shaft should only turn with some leverage---and not by hand. Good luck! Dave Quote Link to post Share on other sites

mikeb Posted January 19, 2006 Author Report Share Posted January 19, 2006 Hi Dave. Thanks for the information on the water pump. If they do leak, I can see that it will come out the slot in the block but can it get into the sump. Quote Link to post Share on other sites

Guest dolomiteman Posted January 22, 2006 Report Share Posted January 22, 2006 If it still leaks with a repair kit fitted, it means one of three things: 1: You were cak handed in fitting the kit and broke something 2: You didn't check the u/s impellar for flatness; they get ridged 3: You needed to replace the block busn in the engine block Water will always come out of the slot when its needing attention, its what its for.

Darren Motamedy Posted July 16, 2006 Report Share Posted July 16, 2006 Hi Dave, I'm a new owner of a 1980 TR7........where did you purchase your pump, and did you use a factory pump, or non factory. I've been told that one can purchase an AC/Delco for TR7-Saab 99, or that Napa also makes one....any suggestions or thoughts?

Darren Motamedy Posted July 16, 2006 Report Share Posted July 16, 2006 Hi Dave, Did you use a stock TR7 water pump? I have a 1980 TR7......how many impellor blades were on your pump? Thank you for any help. darrenmotamedy@comcast.net Mike Managed to get the brass cage out using a three leg puller, with an old spanner across the bore. A bit of a fiddle but it worked.

Darren Motamedy Posted July 16, 2006 Report Share Posted July 16, 2006 Hi Mike, Not sure if you recieved my last message, so here's another. Which water pump did you instal? The stock TR7 water pump, or the AC/Delco pump for TR7, or there is also a pump that fits TR7/Saab 99. Where did you purchase your pump, and for what price, etc. Thank you very much. darrenmotamedy@comcast.net Quote Link to post Share on other sites
