Aluminum Pwr steering pulley alignment
I bought a March aluminum power steering pump pulley before I found out that its a press fit on a sbc and I can't return it. Since it was rather expensive to me, I'm gonna try to use it. I have a few issues that I would like to hear your opinions about.
1. I'm concerned that an aluminum pulley will relax or loosen over time and I want to positively secure it. I'm thinking of putting a bolt with locktite and custom washer/spacer in the pump shaft that will bottom out in the pump about the same time that the washer contacts the pulley, not to put pressure on the pulley, but to prevent it from moving forward off the pump, but what would prevent it from moving rearward towards the pump? That or after the pulley is pressed on, drilling a hole thru one side of the pulley hub and halfway thru the pump shaft the correct size for tapping and installing say a #10 set screw that would bottom out inside the pump shaft. Would that create a bad imbalance or weaken the pulley hub dramatically?
2. I bought a cheap press on pulley installer, and a March pwr steering pump bracket. With the engine block on the stand for mock-up test fitting, I bolted on the water pump and the steering bracket and new steering pump. Its a single groove pulley. I was going to drive the pump with a dedicated belt from the crank pulley. Without the crank and its pulley installed, how far am I supposed to press on the steering pump pulley? Is it supposed to be flush with the front of the pump shaft, or certain specification of depth, or am I just driving blind until I get the crank installed?
I'd appreciate any input!
