Compression Tester
I am parting out my 740 and would like to run a compression test before I pull the motor. Any suggestions for a tester or is there anyone wanting to rent theirs? Thanks for your help.

You can get a cheap tester that works at harbor freight.
Why are you pulling the motor?

Thanks. I'll check it out. The frame is rusted out on the passenger side, some body rust and the frame member below the motor is cracked almost thru. The motor runs great and I have a rust free 84 760 so I want to clean it up and put it in the 84.

Sounds like a good plan.

Your 84 probably has the same crack-prone front crossmember, so check that closely before you swap in the other engine. You may find it needs welding/reinforcement or replacement (the newer ones have reinforced boxed-in sections at the weak points).

I've looked at it closely and don't see any cracks. It's an automatic and the donor car has the 4 speed w/overdrive and is a year newer and 50 K more miles on it. Just a thought.
thanks |

Picked up a tester at harbor freight on Saturday but was only able to get 1, 3,4 injectors out and unable to get the heat shield out of 3. One of the adapters fit in the injector holes so I tried number 1 and only got 110 psi. I tried 4 and got 350 psi. The engine ran very quiet and smooth. Planning on pulling the head anyways but would like to be able to do a compression test. Is there a socket that is made just for pulling these injectors?
thanks |
