Hi looking at your photo it looks like the end of the shaft, where it runs in the bush in the outer cover, is also damaged regards Terry
Indeed you're correct. The photo is actually mine that TT21 has found on the board somewhere and used (and he's welcome to).
See the detail shots below of the same shaft and note the bearing it came out of. This is surprisingly common on RE5's and possibly caused by using the wrong sort of coolant, not adding Bar's Leaks or both.
The addition of Bar's Leaks as the manual recommends is apparently about more than barring leaks. I believe that it also acts as a lubricant.
Long term members will have seen these before but we have a regular supply of new people cycling through:
I've replaced the RE5 water pump seal with a similar sized part from a Davey swimming pool pump..not sure if I still have the part number details.
It just happened that I'd replaced one in the pool and then had a leak on an RE5 I was working on and I noticed the striking similarity.... I got it from the local pump repair shop.
I think I have the info in my notes - will see if I can find it when I get a few minutes.. Replacing the seal wont fix the worn bush in the outer casing though - that will need to be fixed as well for a long term fix to the leak...
That would be me. I had the bushing precision made. It is a very high quality bearing bronze.
To replace, stick an 8mm tap in the old bushing and it acts as a puller. Heat the cover in an oven and drop in the new bushing.
The MOST important thing is to refill the system with some bars stop leak. Not for leak protection, but for lubrication.
I have them in stock as I made several hundred to get cost to a manageable level. I have never had a complaint or heard of a failure and my guess would be they have been in service for at least 10 years.
