View Full Version : TR2/3/3A Crankshaft Pulley Configurations

I have run across 2 different crankshaft pulley configurations. In the attached image on the left side is a solid backed pulley half and on the right is the stamped style pulley half that I am used to seeing. The front half of both are identical. Has anybody else see this style of aft pulley half before?

Interesting. I’ve only seen the right one. Any idea what car had the left version? Any chance it is home made?

Whichever of those you decide to use...be sure to use a speedy sleeve for a good oil seal!

John, the speedi sleeve repair is kind of how I got into all of this. I was inspecting the hub and noticed a deep groove in it and started looking at speedi sleeve repairs and when I measured the hub it had quite a taper on it and it was too small for the speedi sleeve that people usually use. I popped a hub and pulley off of a locked up engine I have and it had a really good hub (with a little pitting in the seal area, so it will need a speedi sleeve anyway) and I ran into this unusual configuration of rear pulley.
