  1. Unless you're very lucky and someone has installed a drain plug in your diff removing the old oil isn't so easy. Assuming you don't want to remove the complete unit then sucking the oil out with a tube fed through the fill hole would be about the only other option....

    Cost. As always.

    So the solid prop is the cheapest to make, and was fitted to Heralds, unless there was an NVH problem. The strap type is only a little more expensive and would often fix the problem. The sliding spline costs more still but is generally better for NVH, which was worth the cost on a Vitesse with its "silky smooth and silent" advertising persona. CV joints were expensive in the '60s but had become common by the mid '70s.

    Orrrr was it that Triumph were too far out on chassis dimensions and it was easier to fit a variable length prop to accommodate the differences😂

  3. Yes that'll do the job nicely! I wondered if the boss was part of the crank balance but removed it and didn't notice any decrease in smoothness. As I didn't fancy cutting the original bolt think I bought one for a Mk2 Vitesse which for some reason was quite a bit shorter.

    I can't remember any great issue with removing the Mk2 Rad other than having to rotate the plastic fan blades to clear the bottom outlet as you lift the radiator clear of the valance, but I'm using the std Vitesse yellow plastic fan.

    One trick I do use is to have a cardboard sheet/plate of the same size as the rad core that I fit over the fin tubes to avoid damage to the fins.

    Paul I'm very interested in your electric fan installation, can you provide a photo of the install. The original Mk2 fan which is fitted to the crankshaft is too slow at idle (700 to 900rpm) with our high temperatures and esp in traffic jams, where you have to keep the revs up over 1500 to cool the engine. An electric fan will run a lot faster OK with a load on the battery but that's what the alternator is for.

    I agree that an electric fan can move more air through the rad at tick over so have a Spal 13" unit mounted engine side. I removed the original fan and boss on my Vitesse and used a shorter bolt plus large washer to retain the crank pulley. The new fan is 62mm deep at the motor, draws around 12.5A and does a fine job.
