Bringing non-runner M1165A1 REV back to life!

[Retiredwarhorses]

Reached out to Pensacola Diesel and Jeremy looked at my video and ID'd the issue immediately: Injection Pump Timing was retarded (engine was not burning all the fuel). With his instruction and this magical tool, I was able to precisely set the timing and now the M1165A1 purrs like a kitten.

Highly recommend Pensacola Diesel for your Injection Pump rebuild. They provide great products and most importantly, follow-through. Ask for Jeremy.

the timing scribe on the pump should be set to the timing scribe on the timing gear housing…that’s the starting point and 99% of the time that’s it…if it needs to be advanced and as I’ve seen on rebuilt pump “extensively” advanced? The pump was calibrated incorrectly…

Yeah, the old pump was over 5° retarded, and with all the work they did to rebuild, it’s essentially a new pump and had to be timed as such.
