I could see the spring, and as I said, I have just over 11mm clearance vane to body. I was out on the bike today, did maybe 30 miles, seems fine.
What a cracking wee bike, sportier than my Morinis, and also very different in character. Feels more modern. Hopefully get down the borders area to St Marys Loch tomorrow if the weather holds, around 150 miles, that will be a better test.
After a couple of thousand kilometers my water pump has failed again.
I noticed that the water temperature was a little high on the ride home and thought I'd check the pump when I got back. To my surprise I found that the pump pulley has worn a hole in the cam belt cover. It looks like the pulley has come partially off the shaft.
It had been such a great day up until that point. Good weather, great roads and the Saturno had been running like clockwork.
That's not good. I always felt there was a lot of stress on the water pump pulley.
Will you be able to loctite or sleeve it?.
Sometimes on cars when that happens there is can be a misalignment on another shaft somewhere? but on the Saturno I can't imagine where that would occur? The tensioner?
I guess the real solution is an electric pump, but you still need to tension that belt!
Please tell us all how you get on with it.
I had the same problem on a pump I made with alluminium pulley, it wore a hole in my Nordy cam cover, the pulley was tight when fitted but expanded when it got hot allowing the pulley to move, back to the drawing board and a rethink.
