I had a couple of mechanic friends come by today to help remove my left planetary. It was not an easy project. We ran into problem after problem and out of sheer frustration, one of the guys said he needs to see the leak before I will proceed. I started the machine and oil was gushing out and around the planetary housing. After a few checks he found that the hydraulic hose that runs above the planetary had ruptured below. It was a big crack about 4" long. I had a big freaking smile on my face because it was only a hose and we saved all that time and trouble not having to remove the planetary in the rain. That would have been one b!tch of a job. My diagnosis was wrong because I was alone when I based my opinion. Since machine creeps forward when started, I could only look at it while at the seat/controls. Is there anything I can do to stop the creeping? It sucks to be me.
I'm told that I can put regular engine oil 10W30 anti foaming for my hydraulic system. What's your opinion? My hydraulic tank/lines are almost empty and it was pumping out air today. Do I have to bleed or air out the system when I start filling the oil as I believe the lines will be full of air now. Also what is the recommended grease for the pins/joints or pivot points on the arms and bucket. Even though that machine is a pain in my butt, I love it so much. If I won the lottery, I'd go out and buy a Case 465 loaded before I did anything else.
Well the parts won't be too bad on that one. Skids are pretty basic, especially the early non electronic models like yours. Often the failures are simple, so try not to overreact to them. Its always a p#ss off when something stops working. But if you can live with a few fixes now and then, you can have a machine that is worth 30% of new one doing the job.
10/30 is used in most manufacturers machines of that vintage and I'm sure will be fine in yours. As for grease I like the heavy red Texas Refinery brand, but any general purpose grease will be fine for the pins. Grease is more about how often you put it in then what you use imo, but heavy, sticky grease can't hurt.
The hyd system should self bleed after several cycles of up and down on the boom and driving the machine around with no load. (don't work it until it quits groaning from the air in the system and quiets down)
As for the creeping this is a very common problem with all brands and there are several posts on the topic, mostly in the bobcat forum but the general procedure would apply to all models.
I a nutshell there are some springs that hold your steering levers in a position that should be neutral on the pumps. One set for each side. The parts wear with use and eventually where the levers stay when you let go of them is not where the linkage to the pump is in neutral.
These need to be adjusted until where the levers sit, is where the pump is in neutral again.
Also common with wear is that one or both of the steering levers does not return automatically to the same location each time it is released, and a creeping problem results, that is worse at some times then others. Sometimes the centring parts are too worn to get a consistent neutral and new parts will be needed. The should no be too astronomically priced as they are common "wear" parts, like say tires, and the factory knows they will be replaced a time or two in the life of the machine
Specifically to Case I can't help you. But take a look and you should be able to sort it out. Read the posts in the bobcat section for general tips on the procedure. Not all will apply to you of course.
