Triumph Pre Unit motorcycle 1938-55 Crank & Conrods E1450 and E1460 – SOLD


Triumph Pre Unit motorcycle 1938-55 Crank & Conrods E1450 and E1460

This is one of the early Triumph twin pre unit 500cc crank / flywheel for the Speed Twin 5t, and T100 models.

The crank is bolt-up type, sometimes described as a Bell crank. Most people refer to it as the “small bearing” type, as opposed to the “big bearing” cranks that had big end bearing shells.


  • Connecting rods: E1450
  • Crank cheek/ bell: E1460

This is a crank came before the “big bearing” engines. I have supplied the numbers, so please make sure it’s the correct crank and conrods for your needs before you go ahead and buy.

The threads are OK.

The connecting rods come with the caps and nuts. The distance between the big end and small end centre-to-centre is 6 ½”. I think you can use conrods numbered E2923 as a replacement (or conversion) for the original E1450 conrods that are fitted.  You will need to make sure of that yourself. E1450 was supplied between 1938 and 1955.

If you can, please come and look at this before you buy it. I’d rather that you took your own measurements.

The price that you see on my advert is for the item and not the item plus whatever taxes might be due.
