Thanks Rick, e-mail sent to you.

I understand the BSP series follows the standard, non-modified Whitworth thread profile.
What I have not found is a 7/8 x 14 in other than BSP. Sir Miles Axlerod from Cars would be impressed. A trail of redundant threads.
"And then I remembered what they said about old British Engines, if there ain't no oil under 'em, there ain't no oil in 'em."

Rick BSW in that size would be about 8 TPI

Don't forget BSC as well (British Standard Cycle) used on motorbikes as well as pedal bicycles.

I think you guys are barking up the wrong tree HOWL
That thread is an engineered thread specified by the designer 1 .187 x 14 threads to the inch This is not unusual when design work is going on
The engineer has specified what it is doing and the weights and torques required
And the shaft will be designed to those specifications
Remember guys there was not a lot of metric going on in Canada during the war yeas
just my opinion again and you are all welcome to put me in your sights

Sorry Stew, but it might be you barking up the wrong tree. Michael copied from the Canadian Carrier parts book that the spindle was 7/8" BSP. Remember the Carrier was a British design and build and Canada supplemented production, British Standard thread forms were used for interchangability which all made sense. Some of the early Canadian built Carrier had British components fitted.

As for metric, you may be surprised to know that metric sized bearings were used by Ford in the gearboxes.

Give me a little while to take some pages out of the machinists hand book
This has been my bible for the last fifty plus years

According to the Ford-Windsor parts manual, - - - - - (Canadian carrier parts bible ) - - - - - the 7/8 x 14 BSPP for the spindles is not the only BSPP thread used on the carrier.
The other (that I am aware of) is where one would expect to see it, on the oil cooler.

If this BSP discussion turns out to correctly be BSP, will I get a free lunch to replace the wager I lost over my opinion on the production technique used for the long shaft of the starter crank?
Is the major centre portion of the starter crank handle hollow or solid? 9/15: (edit:main shaft, not crank handle)
I came in second.
