You may wonder, what does this info have to do with raising Bison?   Well, we have fence and we need to mow around the fence line.  What if you lose steering while you are mowing?  What if you hear fluid gurgling in the steering shaft?  What if there is fluid coming up the steering shaft and out from under the steering wheel.  Below we share what to do if your CASE 480 C has any of these problems. Talking with the parts guy at RPM machinery in Fort Wayne he says there is a seal kit we need to put in the bottom of the shaft.  They tend to go bad and leak their way up the steering shaft.   Sounds like that is happening to us.  Have a photo here.


There is power steering fluid running down the steering shaft and you can see it has dripped on the floor pan.

Purchased the seal kit last week from RPM Machinery and had my mechanic start working to do the repair.  I will share briefly how it gets done, however; you can always check with the guys at RPM, they are great help.

Getting started, remove the steering wheel by removing the center nut and using a puller to remove the wheel.  You may damage the plastic like we did, but there is metal underneath.  Next remove the outer shaft, and knowing that the seal leaked, you will end up with some nasty power steering oil all over the floor and possibly yourself.  There are 2 snap rings that need removed and we removed the lower pin.  There are 2 pins, and again, we punched out the lower pin and off comes the steering shaft.  That leaves the bushing and seals to replace, put it all back together, clean it all up, add more power steering fluid to the pump and give it a go.  Good Luck.

Here is a picture of the finished job.  It doesn’t leak any more, it handles like a new tractor. Well, new for the year it was built.  Happy Mowing!
