Been loving driving my 31 Banger powered coupe and went for a nice leasurely drive today and noticed a new to me noise. Got out to investigate and its the water pump/fan shaft. There is quite a bit of end play. I noticed the shaft may have needed greasing so did that with some effect but the end play and noise is still there. It sounds worse in the video than real life but am guessing it shouldnt be like this. There is no apparent leaks so I guess that's a plus. Do I need to repack this or am I needing to look further. Thanks.
Mine started doing that and I just bought a brand new leakless pump as I didn't want to flying into the radiator
They make a collar that you can put on the shaft to keep it from doing that. Most of the suppliers have them.
Yes, a bearing collar will fix that right up. A bearing house should have them. If memory serves you'll need a 3/4" split collar.
Thanks all! Cheers was thinking I would just do that but none of the normal vendors have them in stock. Cheers I see them advertised, any guidance on fitting them thanks? Do you push the shaft all the way back in its movement towards the engine when fitting it or towards that radiator? Cheers, Will have to see if I can find one here.
Really what you need is to fix it proper with the new leakless kit . They come with a stainless shaft modern seals and the collar to control end play. The collar will save you for now, but next time you order from the states get the water pump kit.

First thing you want to do is piss that fan off, get a 4 blade fan, the 2 blade are known to crack and fly to peices, you don’t want your body or anyone else’s for that matter in its flight path. Plenty of info about that happening.
Mine started doing the same followed shortly after with leaks. Also replaced with a leakless pump. Good so far.
The original 2 blade fans were prone to cracking however the new aluminum 2 blade fans are John Wayne tough. I have heard of no cracking incidents with them as well.

Thanks all. As @rwrj suggested I have fitted a split collar (16mm) and set the end play at .007. Its an interim fix as Im not really comfortable with the collar riding against the pack nut. Whilst I was doing that checked the fan and its aluminium but does have some play in it too. Will order a dissasembled leakless pump fro Brattons (Link below) or water pump rebuild kit (Leakless) thanks @winduptoy and probably a fan whilst Im there as freight will be the biggest expense. https://www.brattons.com/30-31-LEAKLESS-SHOW-WATER-PUMP-KIT/productinfo/12220/
I just looked at the picture and that was my first thought-it is meant to stop the fan going FORWARD into the radiator is it not? The way it is it isn`t gonna stop that .
To be honest I wasnt sure where to place it and couldnt see any pics elsewhere where is should go. Travel is currently limited to 0.07 in either direction.. I've read elsewhere there is a risk of the water pump migrating back into the head damaging it??
Not trying to hijack Pete's post, but how do you tell the difference visually? Or do you just try to stick a magnet to it? I've never paid much attention to the two blade fan on my roadster.
You can see the seam where the sheet metal was welded/brazed or whatever starting to separate plus the spot welds where the tin was attached to the hub. I brought this being a newbie to bangers years ago and could of ended up a **** story. This one was just waiting to cause a minor or major mishap, now a wall hanger for reference.
Actually the stock head has an internal casting for the fan/impeller shaft to ride against there is a washer that is placed between the impeller and the back of the seal cartridge that is supposed to space the shaft against the casting in the head. If you look at the rebuild kit, there are additional shim washers to compensate for the wear in the head. The 'water pump grease' that is introduced into the back zerk is supposed to lube that surface and why it has a screw cap on it from Henry If the clearances are set up, it will eliminate the need for a thrust collar on the shaft. If you have an aftermarket head, it likely doesn't have the internal casting for the shaft to ride on and then shaft collar will be needed to compensate Good luck
