Case 1818

[ranger505]

Hi all,
I have a 1992 case 1818 skid loader recently the tilt bucket was sluggish so I put a new hydraulic filter and new oil thinking maybe it may help. Today I was moving gravel and the tilt and the up and down is real week. I took it to a shop to put belts on it about eight months ago. It has never operated the same sense they put new belts, and when I got it back, the neutral lever does not work anymore sometimes if you have it in neutral and you push the levers to go forward it will still go forward, he told me that the pivot points are wore out on the motors. I'm not real familiar with that. Any ideas if that has anything to do with the bucket lifting or tilting I do have a repair manual I just really don't understand the adjustments. I have about 1300 hrs on the machine.

I also have the 1818 Case. The last two could be the year and it may be a 1986 vintage. It has the ownan eng you said. Mine also but I never had a problem with that aspect of the unit. So I think and it's a guess that one of the motor reliefs could either be sticking open or out of adjustment at the valve bank. You may need to pressure Test the system to find that out. Sounds like lack of pressure to the cylinder rods and that could be the valve bank as I mentioned. If you have a repair manual see it it mentions any of that in the trouble shooting. I don't have mine here now but that's a good start. Any leaks? Are the lockin levers moving the valves where it connects. Off the top of my head. Pull the seat and floor panel to see the routings if you have not done so yet. How's the engine holding up for you? You could have a bad pump also. The pressure testing will tell more. You may need someone who knows more to help you.

One more thing on this some guy told you pivot points are worn? Does he mean the mounting of the pump? If so I don't buy that. Check the belt tensions again to see if they are sloppy. Belts loose? I think one side or pump is for the tilt and lift and the other pump is for the forward and reverse. The issue is with the side that is for the hydraulic lift and tilt. Again if not the belts loose then that leaves the relief valves or that lock in lever not opening the port. All cable engagement. How about the engagement lever on the floor that is another place to look. What that engages etc. Engine drive belt? Engine loose? Small things first my friend. Good Luck with this and keep us all posted.

Do any of you all have any pictures of your case? 1818? I'm looking for pictures on the lines that go to the cylinders that lift the boom I took all four off to get replaced and I'm thinking maybe I have them crossed as they are the same fittings, having issues with the boom going up with a load

I don't have the pictures but I can take some once I get to the unit. Just need to remember. The pictures you want for the main boom lift are where under the floor? Or at what point?

How's that coming along? I have my book that shows the routing. I would need to take a picture of that or tell me where you feel this picture can be taken.

In the above pictures it shows the lift cyl. routing. This is what my book shows. 1818 Uniloader and around the 1993 vintage is my guess not sure how to identify the year. If this helps let me know. The second picture is the parts listing.

Thanks all, finally got around to try and work on it. Belts seem ok how ever the lever on the side used to I engage it to neutral but when I picked it up from the guy that put belts on it doesn't engage into neutral anymore. Don't see any leaks anywhere

Anyone know how to check the belts on the case 1818 they look fine to me but but I think that is my problem not being able to lift anything heavy getting a squealing noise at times

Funny thing I have a similar issue now on mine. I have not done it yet or attempted to. But this is what it looks like should be done. Remove the seat and plates two bolts near the seat upper back rest. Then open the access door for the engine for access These two Pumps can then be loosened where they mount and appears to be one bolt like an old style alternator. Now it a appears to have a tension adjustment bar with lock down nuts once you are at that point I would think a 1/4 turn on that adjustment bolt depending will help Lock the nut and go see how that feels in belt tension. Mine does the same thing squeals but that seems to be the drive wheels that cause that. Not sure of that yet either. One other more access method is to tilt the cab. It may help big time for seeing what is what. If you do that just the support rod to hold it in the up position. Safety is Key. Lets see if that is correct. I got that close and yet did not get it done. Had to leave it sit. Good luck with that. Let us all know. I attached a picture of the controls from the main engagement to the pumps which may give you an idea what I am talking about.

One more thing on this. May want to have two new belts handy they look good but may be rock hard. Good Quality belts not made in Japan or China. They just don't hold up. Rubber quality is not the best.

Thanks for all the info going to try it Saturday

Hi there was not successful in my adjustment. How did you turn out with yours

I have not attempted it as yet. But I need to start working on that little machine. It's my snow groomer. I will be going up soon. Try to keep you up to speed on the findings. Thanks for asking.

Don't forget pulleys will wear out if belts get old and left to run lose especially on equipment that gets a lot of dirt to them, I did not believe this until a guy showed me by replacing the pulleys and belts on a machine and it worked great after that. If the pully is groved (and you can feel it) a new belt will squeal and just wear out quickly.

I agree and where this machine is it's a lot of sand. The reminder is a good one. I need to get two new belts. But first the adjustment to see what that does. My fear is there is another issue with the pump or drive control...

I was looking at the parts breakdown of your unit and if it was me I would take out part 13 and go to a hydraulic shop and get a T and a long hose to fit the T, don't forget to get what is needed to attach a gauge to the hose you add to the T, so I could tap in to the lift function and see how close I was getting to the relief pressure, by raising the boom to the top and dead had the unit, to get the most accurate reading on a pressure gauge you want a gauge that is twice the pressure reading of what you are checking as the middle 3rd of the gauge is the most accurate and get a hose long enough that you can check from multiple places, I used to keep a 6 foot 1/4 hose in my service truck and had a 3000 psi gauge and 5000 psi gauge, so I could cover from 1000 to 2100 psi with the 3000 gauge and 2500 to 3500 psi with the 5000 psi gauge
