Looks great! Very well planned out and executed! Thank you for keeping us up to date.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Yes --- The threads are standard NPT. We were able to clean up the old threads and salvage enough turns to get it to hold. (Red locktite to the rescue).Awesome! I'm amazed that your prelube pump put out that much pressure. What are the thread types on the pump? From your pics, they look to be NPT.
"Post filter" will pump unfiltered oil thru your system, probably not a good idea.OPCOM said:Did you plumb the prelube pump into the pre-filter port? I ask because mine is plumbed post-filter and I've been suggested to change it.
Are you saying that the pressure across your filters is 13 psi? If that's true, then it won't be long before 15 psi is reached and the bypass regulator will start doing its job.SasquatchSanta said:..........
The ambient temperature yesterday afternoon was 16 degrees. The engine was running at 180 degrees. At 2,300 RPM the following oil pressures were observed:
Between the oil pump and the filters: 88 PSI
Immediately after the filters: 75 PSI
At number 6 rod: 62 PSI
I'm running 5 micron 1970 spin-on filters that are rated at twice the capacity of the standard deuce filters (twice the oil pump capacity). Perhaps the stock filters are creating more resistance and being by-passed but unless I'm missing something.....
Yes, and I assumed since the differential pressure was under 15 psi "all was well". Until you mentioned it, it hadn't dawned on me that when the filters start getting dirty the differential pressure will increase and the bypassing will start.Are you saying that the pressure across your filters is 13 psi?

The only thing I know about them is that I got them at CarQuest. One it a 250W and the other is 150W. I went with two separate pads so I could select how much heat I wanted to apply. I "think" the 150 watt unit and one of the two 600 watt freeze plug block heaters will "maintain" sufficient temp when plugged-in immediately upon shut-down. The 250 watt unit and second 600 watt block heater can be added to the mix when starting out cold on or below zero days --- like today. The goal is a dependable 40-BelowZero Deuce.Like your pan heaters, what brand are they?
I agree that a fuel burning heater would be superior. In time, I may remove the now modified under dash M35 heater and install it in an M37. Hopefully, by that time I will have learned enough about the oil burner heater to be comfortable with tackling an installation. It would have to go under the dash. I don't want to compromise engine compartment space.If you want to make use of your second mushroom, install a fuel burning heater and get rid of the hot water heater (which really isn't good for your part of the world, anyway)...imagine starting the heater and have heat within one minute.
No, you do not want in-pan heating elements. I have seen quite a few stick-on pan heaters burn themselves out. The plastic cover melts, burns and drips and the paint catches fire and burns off the oil pan. Unless you have a thick oil trail running down the side of the engine, that is usually the extent of the damage. Takes a scraper and a paint can to fix.SasquatchSanta said:If I had it to do over again I would have installed in-pan heating elements. I fear the heating pads are too exposed to the elements and may not hold up. Hopefully, I'm mistaken --- time will tell. I don’t know what I was thinking --- I had the pan off and installed plumbing for the pre-lube pump and bypass filter return. We could have just as easily installed the plumbing for the oil pan heaters.
Does this mean when 15 PSI is reached ALL the oil bypasses the filters?The bypass valve, as I now understand it, is a regulating valve and will keep the diff pressure at 15 psi, with some oil flowing thru the filters at all times, so when you get to 15 psi, that's it.
Thanks for the insightYou want combustible fluids and electric heating elements (especially household voltage powered ones) well separated...
No, but enough will take the bypass route to keep the pressure differential at 15 psi.SasquatchSanta said:Does this mean when 15 PSI is reached ALL the oil bypasses the filters?
