Hi Guys, I've never posted much over here, mostly hang out over at the Cub side, but I picked a Case 222 up tonight, don't know to much about it, the price was right, so I brought it home. It runs, moves, needs some work on the PTO, (it won't disengage), probably just an adjustment. What was the HP of these machines, I can't find the tag on the engine. It is a Kohler, looks to be about 14 HP? Heavy duty little tractor, they didn't scrimp on steel when they built it, which brings me to my other question, when were these made? Quessing late 70's early 80's?
As two others have already stated, your machine is a 1980 model and it is 12 hp. The last digit of the model number co-incides with the last digit for hp. A 220 is 10 hp, a 224 would be 14 hp and a 226 would be 16 hp. The tractor line began in 1962 as a Colt brand. J. I. Case bought up Colt and put their name on it. In 1982, Case sold the line to John Ingersoll. From 1983 to 1988 the tractors were called Case/Ingersoll's and then the Case name was permanently dropped as the transition period was over. From that point on they were known as Ingersoll's and the brand is alive and well today.
Unfortunately for you, the original purchaser of this tractor went with the mechanical lift for the attachments instead of the optional hydraulic lift. However, the good news is that you could remedy that problem by finding a cheap donor tractor (200 or 400 series) to rob the parts from but it does entail a fair bit of work unless you make this changover during the course of a ground-up restoration. No welding or drilling...... just unbolt and rebolt.
With respect to the PTO clutch, I have the following bit of advice. Your tractor should have the EZ-Adjust clutch in it. Parts are readily available for it but you need to know that this is a $500.00 plus item to buy new. Therefore, you should do yourself a huge favour and obtain a few things in advance of trying to adjust it.
casegardentractors.com is an on-line dealership that can sell you the operator's manual and parts manual that is specific to the serial number of your tractor for about thirty bucks. If your clutch disc is badly worn, or you need a shim kit for that clutch, then they can sell you those too. The large adjuster nut located just behind the fan is a cast item and easily broken by the use of Channelock pliers. It is best to obtain an open end wrench for this task. Sometimes, when the disc is worn too much, you need to swap some shims around in order to compensate for that wear.
In order to do that, you need to disconnect the wire going to the headlamps, pull the hood hinge pin and remove the hood. The bolts holding the cooler brackets to the frame must be removed to allow you to swing the cooler to one side. You can then remove the bolt that holds the plastic cooling fan in place. At this point, the large nut can be removed to access the complete clutch.
If it was me doing the job, I would want to carefully examine the three bearing races to see if they roll smoothly and noiselessly. If they don't, then now is the time to replace them. If they do, then consider the possibility of carefully removing the seals, washing the bearings clean and then repacking them with fresh grease. Bearings fail due to lack of lubrication and from contamination of the grease.
The manuals will give you instructions on how to adjust the clutch and exploded diagrams showing how the clutch goes together. Pay particular attention to the main shaft that the clutch parts ride on. If this is badly worn, then your clutch will not work smoothly and getting it adjusted properly will be difficult.
The point I am trying to make is this. Your tractor is 27 years old and there is no way to know how many hours are on it and whether the clutch is original or relatively new without taking it apart and examining it. A good working clutch is crucial to the enjoyment this machine can bring to you and badly working clutches are a constant source of complaints from owners who fail to understand that a clutch is a "wear part" that doesn't last forever.
Very little else goes wrong with these machines so take the time to deal with the clutch now in a thorough manner and you will be alot happier with your new acquisition than you will be if you try to get by with just a simple adjustment. Something is wrong and I suggest that you get to the bottom of it immediately.
