Hi Y'all,
First post. I've been sent to this site many times over the years by Google searches, but this is the first time I couldn't find my answer without opening my mouth to ask the question. A big 'thank you' for all of the past help you've never known you provided.
I own a small welding business and in the course of work this past year we needed an inexpensive, relatively large forklift. So we ended up with a Roanoke Hustler 12k capacity machine. Pretty good-sized machine that weighs around 16,000 lbs and is powered by a JD 219 diesel 4-cyl of about 60 hp. It's pretty far gone, looks-wise, but is still functional and is getting the job done for our needs. I'm updating some of the maintenance as I get time, but being careful about the amount of money put into it.
Let me describe the issues I'm having, the condition of the fluids, the fluid recommendations from 40 years ago when the manual was printed, and ask you for suggestions if you don't mind.
First, on the hydraulics. The main cylinder doesn't leak at all, and doesn't drift. The tilt cyls sweat a little from the seals, and the two power steering cylinders leak enough to leave a drop or two on the ground when the machine has sat for a day. On a cold day, you can hear cavitation from the pump at idle until it warms up. I let it warm up for about 20 minutes at slightly increasing throttle during that time, keeping the engine speed just under the cavitation threshold. Also, on below-freezing days the power steering and brakes will not work at all until the engine has either run at idle enough to warm the fluid, or is revved up really high after startup - then something seems to unstick and they work normally. But that type of revving on a cold machine is abusive to the entire machine and not something I want to see happen. Finally, the other day I let it run for about an hour at half throttle while I was doing other things, and came back to see that it had puked some fluid out of the tank breather in that time (fluid was in the normal range on the tank sight glass prior to this). The fluid was milky colored and I wonder if it might have gotten to 212 degrees and the water in the system started boiling. I have no idea what fluid might be in the system currently.
Anyway, the manual states the following for the hydraulic system, verbatim: "10 wt (SAE) FC or SD." What am I going to want to use for fluid in this? I can get JD Low Viscosity Hy-Gard locally, and another supplier has Chevron Ursa SAE 10W Hydraulic Oil available at a slightly higher ($72/5 gals) price.
Secondly, the transmission. This machine uses a Funk model 4000 short-drop transmission - it's a 3-speed powershift with torque converter. I know that Funk made many of JD's powershift transmissions, but that's about all I know about them. As far as I can tell, the transmission works fine. I have a new spin-on filter for it, and from a slight drip at the drain plug I can see that the current fluid is red, but that's all I can tell.
The manual says the trans should use the following: "Special Purpose Type C-2 or C-3 oil or equivalent." I have no idea what that type of oil is. Anyone been around long enough to remember this spec and what it equates to nowadays?
Thank you all so much for your help. I know these may be oddball questions, but Roanoke Hustler has been out of business for decades and there's no way to get an answer from them on updated fluid requirements.
