Hydraulic helm pump - wheel hub taper
So it seems that my 30+ year old helm pump on the flybridge has decided to pack it in.
It is an old teleflex pump that can not be dismantled for repairs, so it looks like I am up for a new one.
I see on the new pumps, they all have a standard 3/4" taper for the wheel hub. However, my current pump, and wheel, have a 3/4 to 1" taper.
Am I missing something here or is a standard 3/4" taper actually what I have and I am looking at an optical illusion?
Or is what I have an old style taper and I will therefore need to purchase a new wheel as well?
Anyone encountered this before?
Here are a couple of photos. (sorry for the metric ruler, but I don't deal in inches normally)
(I have not purchased the pump yet, just a photo from the seller)
