OK, another very frustrating night.
I got new FWH. 24 spline.
Turns out there must be at least 2 sizes of splines because the FWH are about 1/2" too small in diameter.
The splines on mine, shown in the picture a few posts ago, are about 2" diameter, roughly. The new AVM FWH are roughly 1.5" diameter. Bugger!
So I set about trying to sort out the old FWH. Turns out one freed up fine after having had a couple of days for the WD40 to soak in. Great!
Unfotunately the other wasn't working because the spline ring in the FWH has basically exploded. It's now in various bits and the casing guide rail type things are really worn. No hope of salvaging that one.
So, I decide I've had more than enough of FWH and I'll convert to normal hubs. I dig out the parts list someone kindly linked way back in this thread and start trying to figure out which bits I need.
I have no idea!!!
It's an 88" 1984 and so I'm checking the right area (part 4, page 40). All the websites I find for parts (Famous Four, John Craddock, Rimmer Bros, Paddock Spare) say that the one part I use as a starting point, FRC3991 (the hub end cap) is no longer available.
Added to which, I have no idea where abouts in that diagram to start looking for parts. Also I have no confidence that those parts will fit these seemingly abnormally large splies.
I am utterly and completely lost
Am I fundamentally missing something?
Do I have different half shafts/splines on here than on most/any other series 3?
Can someone tell me what parts I need, based on the previous pictures and sizes in this post, in order to put normal hubs back on there?
Any advice or suggestions on where to go from here would be VERY welcome and everyone has been fantastically helpful so far, for which I can only thank you all.
Am now going to go and drink beer, bathe in swarfega and avoid admitting to my other half that I ordered the wrong things until I'm in a less snarly mood :S
