need help hot wiring a 4.0 ohv

i have a 4.0 ohv motor that is sitting on a pallet. i need help hot wiring the starter to just crank the motor over. the purpose of this is to do a leak down and possibility a compression test to check the quality of this motor.

one other question what do i need to do to prime the oil pump?

this is the motor.

these are the leads that come off the starter.


what can i do to make this work?
thank you

the motor is not going to start seeing that there is no fuel lines, computer to control the fring order, or the fuel injection. so i think it would be safe

all i want it to do is the crank over with no fire.

You should be able to just use jumper cables. Pos to large terminal on the starter and then jump to the small terminal (s)to crank it over. The 2 terminals in your hand go to the distrubution box on the truck.

The best way is the shaft off an old distributor slide it in and spin it by hand.

i have done that already while doing the compression test. in doing that i wont get a constent rotation of the crank. which the starter will do. i will no use an impact. plus i want to see if there is a difference in the numbers if i use the starter. which most likely will happen.

You would have to pull the camshaft sycronizer out but it is almost impossible to replace it in the right spot with out a special tool. Why not just let the starter pump up the oil while your cranking it, its not like a fresh rebuld where it has never had oil.

the two in red i connected to the positive and the one in black to the negative. and bam the motor cranked. just for heck i did a compression test on the number 6 cylinder. the original test in that cylinder was 120 and this test was 180. i performed the first test by hand cranking and this test was via hot wired starter.

thanks for all the help
