Just did a search to see if there were any new water pump and pulley combinations out there, or did Moss fix their problem set up which I got one of. After driving the 3 for 30 years and after doing a freshen up on my TR3A which consisted of new and up-rated engine parts I noticed a noise while hand turning the water pump. I installed it anyways and there was this loud creaking noise which sounded like it was coming from the pump. So reading about the up-rated pumps Moss had I ordered one from my local distributor. I had to file the key-way down to fit but no big deal "I thought". Within the first couple of months there was this a wobbling noise and you can see the pulley "original" moving around so i and went and purchased a new Moss pulley. Took about 2 hours but I was able to oversize the slot in the shaft by using die grinders and a dremmel tool to fit the 1/8" key. To ensure a tight fit I used some glue to hold it together. After about 800 miles I'm back to the same problem. Pulley wobbling like crazy.
My thinking is to do one of two things. Ether go back to an original rebuilt pump if I can get the original parts without machining the housing and shaft to fit. I was researching the problem on BCF and saw a post Randal did where he said the bearings in the new rebuild kits don't fit and require machining. Got access to old pumps too so I'm not scared to do a rebuild ether but not interested in doing a bunch of machining. 2nd would be is to shove a bunch of hi-temp epoxy adhesive on the shaft and bolt it on and hope for the best. There has to be some damage to the shaft too and I'm thinking the epoxy would fill the voids. Might be crazy on that second set of thinking but getting frustrated . Spent a bunch of $ and time on what should be a simple fix and I just want it fixed for good!
One thing I did notice that the up-rated pump did run a bit cooler. The original pump ran smack dab in the middle of the temp gauge and the up-rated on ran just a bit left of center. Not sure it's a good thing but it must have moved more water then the original one. However the original never had any overheating problems after I fixed the air movement problems.
