Question for A-22 Durant owners

I am trying to take my water pump apart and according to the parts catalog both the pulley and impeller are threaded onto the shaft. I know that the pulley is a left hand thread but I am not sure about the thread on the impeller end. Has any one rebuilt one of these pumps recently. I am not looking forward to finding out the hard way.
Any thoughts welcome

Good question Will....The operators manual only describes how to remove the water pump and that the "lock nut and pulley" are both left hand tread...Might contact Jack Melpass in Magnolia, TX, Jack has had dealings with the impellar as I shipped him the whole pump and shaft assembly as a unit for his A-22...Hopefuly someone can be of more help.

Re: Question for A-22 Durant owners

When I rebuilt mine last year, the impeller was a press fit. On my new stainless shaft with custom-milled impeller, it is threaded with a set screw. The belt pulley is now keyed with a set screw. It's been just long enough ago, that I can't remember for sure how the old impeller was attached, but I believe it was RH threaded. I keep all my old bits, so if I find the shaft I will check it and see.

Will,

Put the keywords "A-22 water pump" in the search block above....Jack Malpass has a description of his experience in removing his impellar, it is in fact 3/8"right hand thread at the impellar end, that was the good news...The bad news is that he broke the shaft off in the impellar in removing it....May want to concider an improvement in that department.

Thank-you for the info.
Dad and I figured that it should be right hand thread but you should never assume
when dealing with something 90 plus years old and rusty.
