The tailgates look like their main purpose is to overload the truck. I guess they increase production but something else to break that needs fixing.

Not that I needed reminding but this summer was especially bad for me. My MX track was flooded for 2 1/2 month's. No sense trying to pump the water with more rain in the forecast. I did some drainage work and ripped the track deeper so hopefully it drains better.

This one admittedly took me a few minutes longer to figure out than it should have. You seasoned Detroit 2 stroke guys would have fixed it over the phone. International 4200 water truck with a 8V71 in it wouldn’t start and of course they ran the battery flat dead trying. Charged and would smoke but wouldn’t fire. I guess whoever parked it last pulled the emergency kill lever and I gather that has to be manually reset before it will start again. Tripped the lever and fired right up. A little more knowledge than yesterday I suppose.

Should be glad it's still there-might need it.
And good to know it works, too often they have not moved in many years. The time you need to kill the engine like when a injector seizes and it starts to run away is not the best time to learn it won't move.

I was always told if an engine starts to run away best route to take is in-line with crankshaft. The idea being parts like flywheel will tend to fly out at 90º to the crankshaft.

I figured it was there because they were prone to run away. I’m also fairly certain not many operators today would know to pull it if it were to run away.

I know someone who bought an IH 4200 new in 1982 with an 8V-71TA (371 HP). The 4200 was specific to the 8V-71 in that it was a shorter hood than a 4300 that used other engines.

A Detroit, sufficiently worn, will still run with the blower door closed. Smokes badly, but will run.
Yes, but probably quit fast enough to toss part out the side.

Also on a somewhat side note a Detroit can run backwards. I'm not referring to ones set up for that like say some boats that have them run that way to balance out the torque effect from the props.

I mean if an operator lets one stall going up hill and then does not push in the clutch and truck rolls backwards. Seen one do that my first year at quarry back in 1968! Lucky someone got the driver to kill engine fast before lack of oil pressure killed it big time. It was an old standard transmission Euclid haul truck.

A Detroit that runs backwards for any more than a few seconds needs a new air filter. I've seen some with filter elements that were mostly burned out and dusted the engine.

And you are absolutely correct about that.
That is what he told me and one of the reasons he bought it but he didn't mention other engine options. I found some reference the 4200 was the short hood (10" shorter) and could also come with a 903 Cummins and I think a V800 whatever that is. Have also seen other engines listed but some could be transplants. I've only ever seen them listed with an 8V-71. It sounds like mechanics didn't like working on them because the engine was half under the windshield. Apparently the 903's weren't the best in truck applications but were very popular in 4 articulated wheel drive tractors.
