216 water pumps

Thanks a lot guys, phil in particular. So I'm after a one hole, do all one holers have the correct mount pattern and the lower casting? Or is it possible to have one hole and either the wrong mount pattern or high casting?

I know about the rebuild kits here, it's just they come in well over $100 after postage costs and whole good pumps go for about $25 in the US... At $100 I'll have to keep using my leeky pump (temp gauge works, doesn't go over 80*C) for a while

Hi All

I've run into the problem of the one hole pump interfering with accelerator linkage, I've run into that on my Pattern 12. My solution was to build new mounting bracket of the accelerator shaft. Decided it was better to build a complete new bracket and shaft instead of modifying the original which I have saved.

If I remember correctly when the bracket and shaft were relocated there was a clearance to the back of the pulley which was solved by grinding a little of the shaft away. I don't have a photo of the new linkage will try and get a good shot of it and post.

I have seen a mix of water pumps both styles having either a four bolt flange or the pulley pressed on to the shaft. If the pulley is pressed directly onto the shaft you have to use extreme care to support the pulley fully as you press it off. Otherwise you can bend the pulley or the shaft.

Photos give you an idea of the problem showing the original the bracket bolt spacers on the upper water outlet are missing to show problem more clearly.

Cheers Phil

wow good info Phil, and it makes me pretty sure something isn't original on mine. After the 15 or so year gap between disassembly and reassembly (and considering I was 14 when I pulled it down) I couldn't remember how it all went together. But things didn't seem right, and I could've sworn my bracket is homemade. There certainly weren't the spaces you mention, and I had to grind a bit of the bracket for clearance on the Tstat housing and pulley. So maybe it was already a different pump, maybe in a previous life the bracket got lost. Are there any close up photos of the area showing an original pump, bracket and bolt spacers? I guess it's going to be simplest to suck it up and buy the rebuild kit. But maybe not if mine isn't an original military pump...
