If you know anyone who could do with a spare body of a brake master cylinder for a 99, let me know. I have one to give away.it was incorrectly put on a Stag. it has been stripped. I have a video on the Stags' brake master cylinder too.
Hey mate, very interesting. I have been through a lot of water pumps, as I used to do a lot of miles in my car, and have had it for 31 years/done 330,000 kms in it. I made the mistake of buying a new Unipart water pump about 6 years into ownership, and it was one of the ones that didn't have the drive gear hardened properly. It shredded the gears and took the jackshaft with it. After that I used to use second hand known shafts, but eventually ran out of them, so ended up fitting an elec pump, which was the LAST thing I wanted to do, but had little option by then as "known good shafts" became rare. At least as important as the bearing is the bush that is in the block for the other end of the shaft. If that is worn, the shaft will move enough to possibly damage the drive gear. Well worth checking, and any doubt - get a new one. There is a special tool for removing them, but I could never find anyone selling them, so I just collapsed mine inward, then it just pulls out, then press in the new one. You are correct, usually just turning the top bolt will "unscrew" the WP from the block by driving the skew gears against each other/drives it up and out. But if the shaft comes out and leaves the brass "basket" behind, it is easy enough to use a slide hammer to pull it out. You can use a hook on the end, but what is better is to use an oval washer or a small bar that will angle through the bottom, hook to the slide hammer, comes out. I have never had a problem getting them out. But be careful. I got a block from a "professional" and when I got it, it had two huge gouges in the water pump mounting surfaces where he had used a slide hammer and a hook, and the hook gouged the holes. I wouldn't have bought that block if I had known it was butchered like that. I have removed water pumps from at least half a dozen Stag blocks, and NEVER damaged those surfaces............ but this bloke managed to. Anyway, keep up the interesting vids. 🙂
Thanks for the hints-&-Tips on water pumps. Cheers Bob
very helpful video for me getting ready to remove the waterpump on my Saab 99L 1974 thanks, Bruno.
