420C right steering clutch slippage.

[JerryB4]

new development in steering department. I suspect new clutches are in order but interested in other thoughts.
I have had no problems with right steering clutch untill last summer, would work fine at first but the longer I ran dozer the more slippage I experianced.
By the end of 1-1/12 hrs when pushing a reasonable amount, right clutches pretty much became nonfunctioinal, repeated a couple of times so wasn't a fluke.
I replaced left side (thanks Levoy) a couple of years ago due to slipping from the getgo not relating to time under use. So I am wondering if anyone has thoughts on what is causing slippage only when it gets warm?
Thanks.

A couple thoughts, easy checks for starters.

How is the adjustment?

Take the cover off the steering clutch compartment and look inside to see if things are contaminated.

Often times it is oil contamination, which tends to get worse as the clutch gets warmer.

Thanks guys, going to look down there tomorrow with a line camera, suspect I will
find contamination. More questions to come I'm sure.
