TR6 TR-6 Water Pump

I noticed recently that my water pump is occasionally seeping water out the weep hole. This is a County brand water pump that’s been on the car about two years. Prior to that I had a Stanpart pump that was on the car when I bought it. It developed a serious leak thru the weep hole. After reading Tom Smith’s excellent wiki article on rebuilding a TR-6 water pump I decided I would like to rebuild my Stanpart pump, but I don’t have the tools to do it properly. I contacted Tom to see if he was interested in rebuilding my pump. He was not, but he directed me to Peter at nosimports.com. I’ve talked with Peter, who has the facilities to rebuild the TR-6 water pumps, but is hesitant to make the commitment without knowing if there’s enough of an interest to make a commitment to rebuild the TR-6 water pump. He estimated he would <span style="text-decoration: underline">probably</span> charge about $125 to rebuild. New currently cost from about $50 to $90, but based on my experience, and from what others have posted, they don’t always seem to last very long.

So, is there any interest? Would you be willing to pay more to have your pump rebuilt? I told Peter I would post this and see if there may be enough interest from those willing to spend more to hopefully have a long-term rebuilt pump.
 
Hopefully your water pump rebuild will work out better than the problems with the Wedge Pumps

I don't have a horse -- er, TR6 -- in this race, but given the often questionable quality of reproduction parts nowadays, I'd be happy to have an original rebuilt.

Come to think of it, the TR6 water pump probably isn't all that different than the other "small Triumph" water pumps....
 
If your gonna have someone rebuild yours. Make sure you get <span style="font-weight: bold"><span style="text-decoration: underline"><span style="font-style: italic">yours</span></span></span> back
 
I bought a County water pump several years ago and installed it. About a year later, the pulley shaft broke leaving me stranded on the interstate. Now we're talking a 5/8" shaft shearing. My old pump had been balanced where the County unit had not. That, compounded with questionable quality steel was cause for a very bad evening waiting for a flatbed until after dark...I was happy to have a reflective top.
My suggestion would be to find a good quality replacement or rebuild your old one.
The company replaced my damaged pump with a new County unit, but I'm not to interested in installing it.
 
Hi Doug, You have mentioned two of the number of reasons I rebuilt my own and took the time to write the rebuild article.

One thing leading to the shaft breaking was that the new pulley was not balanced as you found.

The other was again as you found, the shaft. I had several discussions with several truly knowledgeable people in the world of water pumps. These were some of the top people at companies like Gates and others. They all pointed me to Harold Bishop who is a great resource. I was told by Harold and others that many of the new and especially the cheaper bearings is that the shafts are hardened all the way through. This makes them brittle and without the ability to withstand vibration. A properly hardened shaft would start with good steel and be hardened on the outside leaving the inside soft. And the best of them would then be slightly drawn back to reduce the brittleness. The problem is that the difference is not visible to the eye and that makes it a place to save production costs.

That is why the shaft question became the number one reason I rebuilt mine.

Don, you are right to demand your own back, especially if it has a balanced pulley.
 
The machine shop that rebuilt my engine wanted everything that attached to it, including the water pump and the pulley. My pump was great, but the "balanced" pulley was slightly off. They fixed it and all is well.
