Common issue on the first MX Magnums are how tight the hoses are and rub each other at front bottom of cab where they travel under and connect to tubes. Especially the power steering hoses that supply and return from the Handpump.
Didn't know one of them was cutting into the oil cooler hose/tube assembly......until it was too late, ruined power steering hose. Also ruined the oil cooler hose that is part of a hose/tube assembly that is probably one of the most time consuming to get to and replace.(Pic of new and old)
From advice of others that have done it. I spaced up the cab. I went up 1 1/2". One hockey puck and 1/2" steel plate.
Makes it waaaay better now for clearancing hoses at front lower part of cab. I have it now, that none rub on each other. It was pretty much impossible to make the steering supply lines and the cooler hose to clear each other. They laid right on each other and aren't wrapped from factory. Arrrrrrg..... well I take that back. They rub so hard, they wore thru the plastic loom and then hoses ate each other right thru.
I used metric threaded rod to make a bolt that would work. Fastenal part # in pic. 1 piece is long enough to make make 4 bolts. Cut at 9 1/2 " , weld nut on one end makes it 9" long verses the original 7 1/2" bolt. Drill hole in hockey puck, and punched a 5/8" hole in a 3×3 plate.
Need plate above hockey puck for bushing that goes thru cab channel to tighten against.
The original plate that is still used under hockey puck, is metric threaded, that's why you need metric rod so you can still tighten down original cab isolators.
I didn't go 2" because it was going to be more of an issue with a couple things. But I still have way more room and it works great! Even getting cab air filter out, and fuel tanks in and out from mountings.
Only way to get the front cab mounts apart to replace bolts is you have to remove fuel tanks. So that is the most work in spacing up the cab.
That tube assembly can be sent in and fixed for $450 less than new, or can get whole new assembly for $335 less than CaseIH , from New Hydraulics in Oshkosh Wi.
New Hydraulics doesn't show the other hose/tube assembly (return) under cab 414576A2 but I'm sure they could make you one if they had your old one.
These hose/tube assemblies are for tractor serial #'s with oil cooler cold weather safety bypass valve (last pic shows what it looks like, located under air cleaner)
Few pics for ya. 😉
Yep, I replaced every hose at front of cab, prolly never have to do it again now that I can get to them, plus I did it right😄
