Well after two years of checking this and checking that I went ahead and installed a new Delco Remy 39MT starter. I checked all the usual things, cleaned cables, removed ground post frame connection, added additional ground cables, and finally swapped the old 41MT for the new gear reduction unit. Completely different operation. Very pleased with how the new one works. I was never convinced that I should have to turn on the boost to start the engine and it always had to be done to get it going in most instances.
I'm contemplating doing the same. Should probably have the current starter checked out first.
For those with Cummins engines, have you heard of the prelube starter?

This may be the Prelube Oldtoolmaker was trying to link to:

Most big stationary engines have a prelube system installed,many have a post lube system.It works before starting but has nothing
to do with the actual starter.
One of the first things I did on my coach was put a prelube system on. The pump I bought is smaller than I like and have been looking for a pump with more gallon per minute.
Please stick with the original topic: 39MT Starter installation
Feel free to start a new thread on Prelubers in the Tech Talk section.
This will make it much easier for anyone searching for that topic in the future.
Thanks.
Sorry Brett. I was only trying to point out that if you were changing out your starter there is a factory supplied factory engineered upgrade starter that seamlessly adds the benefit of engine oil pressure before you begin turning your engine.
Art,
No problem. Kind of a tough one, as you say, this IS a replacement for a starter so good to mention here.
But, suspect the topic, as happened before, will blossom into a wide-ranging discussion of pre-lubers for a variety of engines.
To add to the hijack I understand that an m11 does not start until the oil pressure comes up? Does Cummins offer a preluber for a m11? I replaced my starter with the Delco as preventative maintenance but was not aware of a preluber or its need?
Will do some research but I have a hunch the prelube is seperate from the starter,there are some aftermarket ones out there.
Cummins advertises the starter for equipment that sits the better part of a year before being used again. There's a couple of additional oil lines to be run to make it all work.
From the Cummins page:
"Simple Installation. Installing the Cummins Prelub system is as easy as changing a starter. Simply remove your customer's conventional starter and install the Prelub starter. Attach two hoses, a pressure switch, a switch/timer assembly, a simple wiring harness and you're done. Only three basic Prelub models fit virtually all Cummins, Caterpillar, Detroit Diesel and other heavy duty diesel applications. Air start applications can also be accommodated."
