Case Ih MX180

[kcv67]

I have been woking on a 1999 MX 180. It has a P pumped 24 valve 8. 3 in it. Working it on the pto dyno and I had 180 hp at 1890 rpm. I pulled the waste gate hose and it had 230 hp at 1890 rpm with 25 psi boost. I then plugged the waste gate hose and am going to leave it plugged and make it one good tractor.

YEEEEAAAAAHHH!!! But now, how the heck do you hook it up to the ground?!?!?

 

[kcv67]

Lots of weight on the front and it is a 4x4.

 

[HHhuntitall]

Soooo, you gonna triple the rear and dual the front???!?! :-laf

A good way to find the weak link in the drivetrain.

NO DOUBT!!! :-laf I bet we'll find it in the transmission clutches on the powershift section... . Just by the old design, that was the weak link. But it you shift gears and get it where it needs to be before it loads up, it will probably hold up fine. They used the predecessor to the current trannies in the 4870 and 4890 at 300+ horsepower, and they'd hold up fine as long as you didn't shift the powershift with the plow in the ground. Maybe a weak spot in the torque limiter when it REALLY starts pulling good... ...

Actually the Case transmission fron the 90 series tractors has NOTHING in common with the CaseIH Magnum powershift. The Case is a 3 speed powershift and is one of the biggest POS transmissions I have ever driven or repaired. While the Magnum is 18 speed. The Magnum transmission is a IH designed powershift that was not used before the Tennico buyout. If you look at the transmission in the 5088 through 5488 IH tractors and then compare to the Magnum powershift you will see that the transmission case is almost identical. The Magnum MX 180 transmission is basically the same as the higher horespower tractors. There are really no weak links in that transmission, I have seen some of those tractors with well over 20,000 hours on them with the original transmission. I would say that as long as the cooling system can thake the added horsepower you are good to go.

 

[HHhuntitall]

Really?? Wow, I'm gonna have to check that out! I presumed it was a newer Case design after the merger, and seeing as how they usually just build on what they already have... ...

IH was working on the 18 speed powershift for quite a few years, they wound up in TOUGH financial shape and never tooled up to factory produce the powershift. Really the only CASE carryover to the Magnum tractors was the CDC Cummins 8. 3 engine and the design of the hood. The cab is the same as the 86 and 88 series IH cab the differential and transmission case is carried over from the 88 series IH tractors. Even the front and rear axles were IH units. Just to preface this, I am a IH collector, Used to farm with all IH tractors and am a member of the RED POWER forum. This is all IH collector stuff. OH I used to work in a CASE ag shop and have had MANY of the 70 and 90 series case transmissions apart. .

The reason for the Case carryover to the CDC 8. 3L engine was because I-H didn't sell the Melrose engine plant to Tenneco, but kept it for producing DT series engines for the Truck Group and ended the source for I-H tractor engines. The Melrose engine plant was originally a Construction Equipment Group plant and the DT466 began as a Construction Equipment engine.



Gonzo 1066, do you remember the split rocker arm (stamped steel/spot welded) problem with the early DT466? BTW, I've also been a member of Red Power forum (read only) since May 2005 and subscribed to Red Power Magazine a long time before that.

Bill, I have updated a number of those early stamped rockers. Apparently Melrose did not quite understand the stresses they were subject to. . My 1066 and 666 pulling tractors however are both running the later stock IH rockers and have held up to a bit more horsepower and rpm quite well. Although I have lost a couple of valve rotors on the big engine. The Cummins 8. 3 has proved itsef to be a excellent engine, both in ag and industrial applications. While the IH 466 is quite prone to cylinder cavition erosion seems the Cummins will wear the sleeves out and not show any evidence of the dred cavitation. .

 

[Bill Stockard]

Yep, I agree. The Cummins C-series has been an excellent engine. In fact all the original designed, engineered, manufactured CDC B and C-series engines have proven to be very durable.

There is one Magnum in our county that had 23,000 hours on the original engine more than 10 years ago. . I lost track of the unit so I dont know if it is still doing farm work.
