Re: Colorado Prohibits Military Vehicles on Hwy
Agreed with ODAddict. Michigan law is different, at least for now, but my M37 is titled as a "Dodge pickup truck". No mention of military design or use.

Re: the $3000 Fuel Filter
I try to avoid any ethanol blend gasoline in my old vehicles, so the Racor unit is just for separating water. I was stranded once in my Studebaker when the accumulated water in the tank made it to the fuel pump and froze on a winter day here in Michigan. Don't care to repeat that experience.

Re: Original Brake Lines With Funk ??
New lines (preferably nickle-copper or stainless). If the old lines have gunk in them, it's probably from moisture being absorbed by the DOT3 fluid. And if that's the situation, then the original steel lines are probably rotted from the inside, and are a leak waiting to happen. Not good with a singl...

Re: Trailering with Uhaul
7500 GVWR is not enough. You will be on the ragged edge. (The weight of the trailer has to be added to the truck weight.) Agreed. A 10,000lbs (or heavier) GVWR trailer is better for hauling an M37. Just remember to check your state laws regarding trailer and tow vehicle ratings and license classifi...

Re: Oil pump leak
Good on the no sealant. :) Those are small fasteners, so not much torque is required. The O-ring does the work of sealing, not the clamping force. With a dry oiling system, such as after an engine reassembly, I prefer to pre-lube before first start up (also recommended in the TM 9-1840A engine manua...

Re: Oil pump leak
Yes, I'd first verify the engine oil pressure using a known good mechanical gauge. If the oil pressure gauge worked fine before, it's unlikely that the sender and gauge are mismatched. Is the wiring to the oil pressure sender and gauge still good? Check to see that the sender and gauge are getting v...

Re: Oil pump leak
Good point, NamVet. In suggesting the cleaning, what I should have really posted was to identify the cause of the leak, and fix it before reassembly. Just a bad O-ring, or something else, such as a nick in the oil pump body or cover plate that prevents the O-ring from being compressed as designed?

Re: Operation Restoration (2009-20??)
Been there. My old frame had been abused (cracked and welded, then torch cut to install an MU2 winch... :( ), so I did the frame plumb bob measurements per the manual (TB 9-2300-247-40, Tactical Wheeled Vehicles: Repair of Frames ) 100_8761.jpeg 100_8760.jpeg Not good. I ended up buying a replacemen...

Re: Oil pump leak
Yes, you can remove just the cover, and replace the O-ring gasket. Screenshot 2023-05-07 at 8.44.35 AM.jpg Just be careful not to let the outside rotor fall out of the pump when the cover is removed, and replace the cover with the same side towards the pump internals. As I recall (been awhile since ...

Re: Valve Seat Angles
I don't rev fast enough or have enough carb to even think about needing to port or polish. The rough surfaces keep up turbulence and help keep the fuel atomized and entrained in the air. And the flow in a flathead is a joke at best. There was a reason for the compromise of the F head in Jeep "...

Hi All, This is a timely post since we were playing around with grinding some seats yesterday in what has become the world's slowest engine rebuild! There have been some rebuilds here (mine included) that have stretched out for years... :cry: We're using Sioux grinding equipment and it's been a lea...

Re: Valve Seat Angles
I'm not sure of the history of the 20deg angle. The more common 30deg or even 15deg would work, at least as far as defining the upper boundary of the valve contact face. A flow bench would give some feedback as to which angles work better, but I've never seen a flathead block on a flow bench. The in...
