the e9 was used in tanks at one point From what I have heard!

. . .

Just my opinion, but if you’re going for a big rig tires, you’re probably beating a dead horse with a Dodge frame. You might wanna look around for something a lot bigger to start with good luck…. Bob

really no comparison, when you are looking at older mechanical engines and trying to compare to newer electronic ones. The L-10 topped out at 300 hp mechanical, but was more common at 240hp or 2 hp over an old 6-71! Gear ratio/tire size also makes a big difference. The whole truck has to be spec'd for the job to make the most of any one component.

This bears repeating I think. In a nutshell, this-

Thanks for that very well put and to the point …this is exactly what I’ve been talking about way too many years of political thieves,,,, getting rich off American taxpayers and giving nothing back but excuses… ridiculous… bob

I recently just did the kingpins in my 05 Mack Granite with an 18k front axle. Im getting mixed answers on how to tighten the big bottom cap. Some resources says 250 ft lbs amd back off, others say 250, then final torque at 600 ft lbs. When I tighten the cap to 250ft lbs, I cannot move the spindle at all.(all steering connections disconnected).

I ordered any new triaxles with the c12 and later the c13 they did a good job I had a c15 515 hp. tractor and a lighter c12 tractor the c12 would run along on the flat but the driver of the c15 said as soon as you could see a hill coming the c12 would start losing ground. I got to run a Cat 3408 and that was a whole lot different than the 350 Cummins I was driving

Worked on Deere engines in river tow boats.

Yea I never drove one or really been around an L10 but I routinely heard they were small workhorses with above average to excellent reliability.

3406 is over 14L, L-10 is 10 liter, not a fair comparison. L-10 was kinda gutless but it was small and topped out at 300hp in mechanical form and 330 in electronic at the end of its life. It was replaced by the M-11 a "stroked" version, that was electronic from the get-go and that got power up over 400 hp. I had the experience of driving both an L-10 and a 3306 which were a closer comparison, in the same service with the same loads, and I felt the L-10 was slightly better than the 3306, both were 300 hp and the Cat blew the timing gears early in its life, the L10 lasted a lot longer. IIRC I got in the mid 6's for fuel with the L-10, about what my 6.9 did in my service truck! Both Cat and Cummins were pushing these small displacement, mechanical engines as fuel savers, over their large bore engines.

I know a guy that stuck a 237 in a Euclid. That was only because he had it around and knew it was a good (free) engine. It was only like a 25 ton truck, and it worked ok.

I've seen plenty of stationary equipment with John Deere diesels as stock power. As for Mack ever being asked about selling bare engines for equipment use kskarbel would probably know the answer.

It has nothing to do with pressure, it has to do with an inverted U bend (at the top of the housing) that is above the inlet and outlet. It forms a pocket that holds air. You can have gravity or pressure on the coolant and it still will not cause the air to go below the coolant level to pass out of the pump. If you force the coolant in under pressure, you will compress the air trapped but not eliminate it. A vent line from the top of the housing allows the coolant to push the air out of the housing, gravity is more than enough to do this if there is an outlet at the top. If the outlet to the block was at the high point of the pump housing it would not be needed, but that isn't how this pump is made. By getting the air out of the housing, it makes the pump move coolant more efficiently, and leaves no air bubbles in the coolant to break on contact with the hot block and cause cavitation damage. All engines have some way to vent any air out of "high spots" in the system. Some have a small hole in the thermostat or a place where the stat doesn't seal off so air can pass. Others with Weir-stats, have a vent line to the degassing tank on top of the radiator. Air will not dissolve in coolant, it will always try to be above the coolant, if you provide a trapped area with no outlet with coolant below, it will occupy that space. Having an air bubble trapped in the top of the pump housing is like running a boat propeller 1/2 out of the water!

Our stationary kohler generators around my city have John Deere engines, as well as 2 of our portable water pumps. One is a 1 MGD, and the other is a 3 MGD pump. Made by Godwin. I did build 3, 3179DF engines to be used as powerplants for water trucks. But thats all i know.

When you filled up 1693's with coolant you had to be careful about air causing overheating

The dealer talked me into buying a triaxle with the L10 for where I used to work, I drove it maybe 70 miles back from where I had a company install the flatbed and I was shocked at how gutless the truck was we had one with a 3406 and it was a screamer compared to this new truck

Come to think of it, a Detroit water pump is down really low so plenty of atmospheric pressure to lift any air out Paul

I use this to refill my trucks, tractors and equipment when doing a coolant refill. They honestly work great and they aren't real expensive. https://www.cpsproducts.com/product-details/550000/

Seems like mack and John Deere are about the only 2 companies I can think of that really didn’t have their engines in anything besides what they built. Kind of a shame since it seems the L10 Cummins was a flop from what I’ve heard and think the e6/e7 could have been a good fit for an alternative. Just a thought I had. I enjoy reading about management history of these companies and deals that happened behind closed doors

Because Mack built motors properly Probably need a bleeder on a Cummins as Cummins were susceptible to cavitation Detroit (2 stroke) I have never heard of any cavitation issues IH was like Cummins and renowned for cavitation problems Paul

Floor boards ??? Hope the termites don't eat it 😯 Paul

This didn’t begin Friday. Carter started it. He watched the Islamic Republic take power, watched American diplomats get seized and paraded on television for 444 days, spent the rest of his presidency negotiating with people who had already told us exactly what they were. Reagan facilitated it. October 23rd, 1983. A Hezbollah truck bomb funded and directed by Iran killed 241 United States Marines in Beirut while they slept. The deadliest single day for the Marine Corps since Iwo Jima. Reagan’s response? Tehran was heard clearly and never forgotten kill enough Americans at once and America will leave. That lesson became the operational blueprint for every Iran-backed proxy attack for the next forty years. Clinton ignored it. 1995 — a car bomb in Riyadh kills five Americans. 1996 — Khobar Towers. A massive truck bomb kills 19 United States Air Force personnel in Saudi Arabia. Nothing. 1998 — Embassy bombings in Africa. 2000 — USS Cole. Seventeen sailors killed. Clinton launched missiles at an empty training camp and an aspirin factory. Eight years. Hundreds of Americans dead or wounded. Zero consequences for Tehran. Bush handed them the keys. He called them the Axis of Evil correctly. Then invaded two countries simultaneously and handed Iran the greatest strategic gift in its history. Iranian Quds Force operatives flooded across the border funding, training, and arming the militias killing our soldiers. And the response was to continue the war while avoiding direct confrontation with the country killing our people. By the time Bush left office Iran had deeper influence in Iraq than we did. Obama funded it. This is where failure becomes unforgivable. The Green Revolution of 2009 where millions of Iranians in the streets begging for American support ignored. The protesters were crushed. The regime survived. Then came the $150 billion in sanctions relief, sunset clauses that expired within a decade, zero restrictions on ballistic missiles, and zero restrictions on funding proxy terror networks. Then came the cash. $1.7 billion. On pallets. On an unmarked plane. In the middle of the night. Delivered simultaneously with American hostages. The regime used the imagery as propaganda for years and used the money to fund Hezbollah, Hamas, the Houthi expansion in Yemen, and the proxy militia networks in Iraq and Syria that spent the next decade killing Americans. Obama literally funded the apparatus that put the drone into Tower 22. Biden surrendered to it. 160-plus attacks on American forces from October 2023 forward. American soldiers killed in Jordan. Two Navy SEALs lost at sea intercepting Iranian weapons shipments to the Houthis. Houthi missiles disrupting global shipping lanes. Iranian proxies running operations across five countries. Three Georgia soldiers died in their beds. Then came Trump. He looked at forty-five years of this record and did something no president had done since the hostages came home. He said no. Maximum pressure. IRGC designated as a foreign terrorist organization. Sanctions reimposed. The JCPOA abandoned. Soleimani the architect of Iranian proxy violence across the entire Middle East, personally responsible for hundreds of American deaths killed in a precision strike in January 2020. The regime paralyzed. The proxies recalibrated. The nuclear program set back. For the first time in four decades the regime faced a president it genuinely could not predict. Then Trump left office. Biden came in. The pressure evaporated. The appeasement resumed. And the regime, patient as it has always been, went back to work. And now we’re here. So the next time someone tells you this is Trump’s war tell them they are brainless twats. This isn’t Trump’s war. This is forty-five years of American presidents refusing to finish it and one president finally deciding that the bill comes due. If you are not capable of comprehending that move to Iran and defend the regime personally. Insurrection Barbie

Of course you don't. I could have bet money on it!
