PS pump test fit

First I needed to get a donor PS pump ready. I wasn’t going to test install a greasy, dirty used pump on my nice newly painted engine! Also pictured are a used PS reach rod, ram frame bracket and the pump bracket that attaches to front exhaust manifold screw.

Parts all nicely cleaned up. I will do a pump rebuild later and sandblast/clean and paint. For now I’ll just re-assemble for my alignment check.

Pump fitted and belted to the front crank pulley. I made sure the pump was in the correct position with all the flat washers in place (next to the manifold ) on the pump adjusting arm and lower pump mounting studs. But there are problems.

The crank pulley is pulling back on the belt. It needs to come out some. Another check of the parts book shows a special pulley for the Jet Thrust engines. The one I’m using (#533890) for standard V8s is different from the proper one #1557898. I checked with a few online Studebaker vendors for one, but no luck.

Regular Stude V8 engines used a spacer (#534294) behind the PS pulley to line up with the PS pump. I happen to have a used one so I put it on to see how things would look.

Now the crank pulley is too far forward. OK, I can work with this.

I held a straight edge across the lower pulley and checked the alignment difference with the PS pulley. The gap you see was about 3/16″. If I remove that much from the crank pulley spacer Then the pulley’s should line up nicely.

I’ll have to send the pulley out to be shaved before I can continue with the install of the intake and PS pump.

Here’s the cut down crank pulley. I put it on the engine but it didn’t line up. Somehow the machinist and me got our wires crossed. Instead of removing 3/16″ he cut the pulley back to 3/16″ so now it is too thin! As luck would have it I have another so I will take it out and have it done along with a rebuild of two king pins for the front end work I’ll be doing during the engine swap.

In the meantime the never-ending cleaning, sanding and painting goes on!
