Re: Hello and trying to fix wipers.

I would also suggest having Fickenhttps://rebuildingtricowipers.com rebuild your motor. Once that is done and the other suggestions Ross made are completed I suspect the Nash vacuum pump output will be more than adequate to keep the wipers moving -- but at a slower pace as was typical of other vacuum wiper cars of the era. Also a good suggestion is to check and or replace hoses -- even the one going to the washer vacuum control solenoid. If the balance valve is still installed after the crankcase aux pump was removed make sure the old aux input port on the valve is tightly capped.

If you decide to try the 12v aux pump make sure and check if the pump you select is rated for continuous running. Many are designed to run only for fairly short intervals when brakes are used -- just long enough to replenish the reserve vacuum reservoir. That type could overheat and be damaged if run continuously for a long period as might be needed when wipers are on.
