Some what old school
First item up for business, the mounting flange for the pulley on the EV electric motor to power the power steering pump.
This will require turning a 1/2" by 3" square steel plate into a drilled, threaded circle and welding it to a bushing blank.
Mission accomplished. Next would be the making of a mounting plate for the hydraulic steering pump. The design would need to solve two problems. First, holding and aligning the pulley to the driving pulley below and second a method for tightening of the belt.
This would require the making of a 1/4" plywood pattern so the design could be tested and adjustments made easily. With the pattern finished it was on to the real deal.
A bit of sawing with the hacksaw and the mounting plate slot was done. For adjustment a small plate with a 3/8" hole will be welded to the lower end of the plate. Just below the mounting plate a threaded 3/8" long nut will be welded to the EV motor mount plate. When a 3/8" bolt is placed through the hole, threaded into the long nut and tightened it will cause the mounting plate and pump to move back tightening up the belt. The bolts in the slot can then be tightened and walla! Problem solved.
Moving on... cutting the axles. Because I am using the Omni transmission I need that end of the Omni axle and not the outboard end. Problem solved? Not quite.
With the outboard end of the Caravan axle (lower) in the Caravan wheel hub and the transmission end of the Omni axle (upper) in the Omni transmission the real challenge is going to be cutting and welding the two together. Can this be done? If it was easy everyone would be doing it right?
More trouble. Then if you remember one of the triac bearing on one of the Omni axles (left) was missing its needle bearings. This will require repair or replacement. What do you think are the chances that the needle bearings from the Caravan can be used to solve this problem?
