Fanalone restoration

[ncundy]

Chugga,
These are the two types I have. The later has a cast impeller and a deeper pump chamber with 2282848 stamped on the back. The earlier has a brass impeller with a shallower chamber with 2189801 stamped on the back. The drive shafts are different as well.

In the photos the early pump is on the left and the later on the right.

Cheers
Neil

Water pump kits turn up on ebay from time to time, I bought a kit about 5 years ago, but as my water pump was replaced/overhauled during restoration I've never had it apart, so it might not even be the right kit for my 2c, I'll dig it out and take some photos as it came complete with shaft and seals, but not the impeller.

The last piece of inspection before putting it the head on (water pump will have to wait a bit) has been the cam sprockets. Hmmm........ not so good. Throughout doing the head (if you've been following  ) evidence has been thrown up of something happening in the past and a bodge job being done to get it all back together.

More evidence now on the verniers.

The inlet sprocket has a broken tooth and evidence of damage on other teeth, and the exhaust sprocket has bad wear and damage on one tooth and three others with cracks/damage at the tooth root. Both wheels have scratch marks across the face of the sprockets as well. Broken chain, over-revved and chain came off, broken tooth causing chain to come off ? Not sure I'll ever know for certain, but I'm trying pretty hard to make sure it doesn't happen again the first time I turn the key  

If anyone has a set of good condition verniers they would be willing to sell please let me know.

Thanks
Neil

Operator error, pressed "quote" not "modify" - sorry

I does look like the chain came off. What's the tensioner like?

[ncundy]

I think you're probably right. The tensioner is good, a bit of wear on the pin that takes the curved pad yoke, and a bit of wear in the yoke itself - but the face of the pad is excellent (almost like new)..................in fact thinking about it perhaps too excellent

pretty sure i've got some pulley's , will have a look tomorrow for you

[ncundy]

Thanks James.

Brian,

Although the shafts, cases and impellers are different I'm pretty sure the seal is the same and it is nearly always the seal that goes. They're like hens teeth, so worth holding onto.

Thanks Neil,
I'll try to remember to take photos when I go to change over the battery of "Fays" Airchamber tomorrow.

Here's the photo of the kit I bought, is there any percentage in smoothing of the rough casting of the impeller, or does the rough casting give it a greater surface area and "grip"

This is one of 3 boxes I carry with an assortment of spares, besides a few other items I tend to work on the hopeful assumption that if I carry a spare it won't break!

Smooth is better than rough - its like a propellor or an aircraft wing or an engine inlet tract so the aim (for what small benefit is to be had...) is to reduce drag along the surface.

Thank you David, I'll get the rotary stones out!

Interestingly that is a completely different seal to any I have seen, however it looks as though it will fit ??

Hi Neil,
Never had a water pump apart so I don't know if it will fit or not as the case maybe , however looking at my parts list Tav 23, the seal looks similar bearing in mind it's an illustration rather than a photo, the bit that does concern me though is that the shaft shown has a thread opposite end to the spline, which after passing through the bearing, the slinger, the spacer(no part number given ?) the seal, and the impeller, there's a tab washer, a plain washer and a nut. so perhaps the kit is for a later version of the water pump with a interference fit of the shaft to the impeller?
Anyone got a photo please.
