What hydraulic fluid would one put in the system for the 6 way blade?
You didn't say what series you have, I am guessing it is an early 450. The info. is in the service manual. You can download it here. -------> http://files.minnpar.com/partbooks/...AWLER DOZER MANUALS/Case 450/case450crsmi.pdf
When we ran the early 450's in the early 70's it seems to me we used the HL32 hyd fluid in them at that time. Likely still widely available?
Thank you ! sorry for late relay I did not get a email!
