I have documented my installation of the Unisteer Gen 2 power steering pump to my sbc. It pertains to short water pump engines with the desire to keep the alternator on the driver side. My alternator bracket is a March product from Summit (MCH-20131). I bought this bracket because it is a non-header mount bracket that keeps the alternator on the driver side. Plus it looks cool
This past weekend I finally finished the installation of the Unisteer Power Steering Pump from Summit (UIS-8060190). I actually believe my installation is the 1st of its kind...you'll see why if you follow along.
First, here is the picture of the pump and reservoir right out of the box (after I used the green side of a sponge to dull the pulley and bracket surfaces, haha):
Here is the backside. I have labeled the tapped holes of the pump to more easily explain my "custom" installation.
Note that the mounting bracket was originally bolted to in the lower position, while the turnbuckle was bolted in the upper position (turnbuckle more evident in 1st picture). This configuration DOES NOT FIT my setup due to the March alternator bracket interfering with the reservoir. When I realized this, I spent about 2 hours trying to figure out what to do. Then it dawned on me that I could move the pump bracket to the other positions on the pump.
"MID" doesn't work because the reservoir moves out too wide and interferes with the A-Arm bolt. However, Moving the bracket to UPPER fits the bill. Here is what I mean:
So this is the packaging result on the car:
I actually think this configuration looks better than the original intended configuration by Unisteer. The setup is more compact, and it it sits lower, which makes the pump pulley almost the same height as the crank pulley. This provides a better wrap angle around the pulley than if the bracket was attached to LOWER.
The problem was not solved yet though, as I still needed a way to hold the pump rigid. My solution was to run a turnbuckle on the backside of the pump, from LOWER all the way up to the bolt that runs between my alternator and the alternator bracket. Here is what I mean:
I used the existing turnbuckle eyelet ends that came with the pump. However, I ordered the center section from www.midwestcontrol.com
It is a 9" long aluminum hex bar with the correct tapping 3/8-24 (PN AHT6-9.00) Here is the upper end of the turnbuckle on the backside of the alternator bracket:
That center section was a $5 part with $15 dollars shipping, haha. But when it is all said and done, I think my accessory drive system looks pretty awesome (note the turnbuckle behind the pump and alternator):
A better view of the setup, although the pic was taken before I installed the pump turnbuckle:
Hope that this write up will give some insight into another drive solution for a short water pump setup!
