Someone with a 3 cyl 4000 SOS?

Ultradog MN · Oct 9, 2019

I have to modify this gas 4200 nose so I can use a diesel oil bath air cleaner.
This cross bracket - I call it the bridge - has this cut out in it.
I can't remember if this cut out is for the SOS cooling lines to the radiator or if it is for the power steering lines going down into the bolster. Maybe it's for both?
If it is for the cooling lines I would think any 4000 SOS would have the cut out and I'll simply change the bridge to a diesel one I have. If it is for the steering lines I need to do more planning.

Anyone got a clue?

my 4000 doesnt have that cut. But mine is a utility not a row crop.. the trans cooler lines on mine come down the shroud on the radiator and then under the radiator.. hope that helps... if pics are needed it will take me a couple of days..

Thank you Robert.
That's what I needed to know.

One photo in my service manual shows the power steering lines routing down the left side behind the radiator, parts book shows the 4200 SOS cooler lines coming forward then dropping down and going back to the radiator, 4000AP SOS cooler lines run under the radiator, thru the bolster then up and back to the front of the radiator, this leads me to believe the notch in your 4200 grill shell is for the SOS cooling lines.

I changed grill shells on my 4000 but on another conversion we welded the oil bath mounting tabs to the gas grill shell and cut a hole in the right side of the bridge for the diesel air pipe
