Please see availability below. Which Manual Do I Need? There are 3 main types of International Harvester Tractor manuals, each with a specific purpose. Some manuals combine types (i.e. Parts + Operators, etc.), but the basic function of the manual types remain the same and are as follows:.

Service Manual (SVC) - The service manual (a.k.a. Shop manual or Repair manual) tells you how to take the International Harvester Tractor apart, fix it, and put it back together. It is written in the language of a mechanic and may include valuable detailed information such as specifications, torques, ranges, etc. If you are serious about repairs or restoring, you need the service manual. Parts Manual (PTS) - The parts manual has exploded views of all parts on the Tractor giving great detail on assembly and disassembly. It also includes a guide for ordering parts.

It picks up where the service manual leaves off. If you do your own repairs, you need the parts manual. Operators Manual (OPT) - The operators manual (a.k.a. Owners manual) is the book that came OEM from the manufacturer when the International Harvester 986 Tractor was purchased.

It gives the owner/operator instructions, shift patterns, capacities (anti freeze, crankcase, oil, hydraulic, etc.) and adjustment procedures (brakes, clutch, etc.). This book is a critical tool for operating and maintaining your machine.

Guys My wife and I recently purchased her parent's farm and by doing so I've inherited a lineup of equipment in various states of disrepair, but mostly toward the scrap side of the scale. Anyway, I've got a 986 that I believe the clutch is not adjusted properly and was wondering what the best source would be for a service manual. I think the clutch is out of adjustment because I can depress the pedal on a hillside and have the tractor stop without rolling backwards even with a full manure tanker. I've been told they were having shifting issues with this machine such that it would seem to get stuck in two gears simultaneously.

The cure for this apparently is to go under the cab on top of the transmission and try to twist the linkage for the H/L/R/P selector until the transmission freed itself. My guess after driving this tractor is that the clutch isn't releasing and when they were shifting from a forward selection to reverse or park they were doing so by brute force in the cab putting a lot of pressure on the gears and the rocker shaft on top of the transmission causing the linkage to jump halfway out of gear and get stuck. This is just a theory though. I just want to get a manual and see if I can get any better results. Thanks Jesse. And you can still get factory service manuals at your local CaseIH dealer.

If you need to adjust the clutch, though.read this.our own Farmall Doctor wrote this out several years ago, and I keep a copy of it on my computer and in my service manuals. This is THE way to adjust your clutch.it's much better than the service manual.

I thought i'd put this here since I seem to type it out often. Not that I mind, but my typing skills are not that great.

This is a good reference to set up the clutch, TA and trans brake adjustments on all of the '06 through '86 series tractors. I have found that these settings are the best to provide the best performance from these great tractors.don't let anyone tell you that you can't shift them!!

First thing that I do is disregard everything that's written in the service manuals. Not that they're wrong, but when they are set up right they shift nice up and down through the gears if you 'think before you shift' hehe. Check that when the TA is forward in Direct Drive position that the snap ring is bottomed out on the spool- this is VERY important!

First thing to do is to set up the clutch with extra free play. This is usually to your own liking, but I set them up so that the tractor starts to move when the heel of your boot is still on the floor.

This makes it easier to feather the clutch for hitching equipment or moving a few feet in the lineup at at the elevator. Don't make any adjustments on the booster, only on the turnbuckle going on down to the clutch release shaft (which requires a 9/16' wrench to loosen the locking block and a large flat screwdriver to turn the adjusting screw on the '86 series and two 15/16' wrenches on the older models without the booster, or two 3/4' wrenches with a booster). Once you have this adjustment where it is comfortable, make sure that the lube oil tellite is operating on the dash. It should come on when the clutch is pushed all the way down. Adjust the linkage so that when in High range, 3rd gear the light should go out just before the tractor starts to move as you slowly let the clutch out. Now adjust the transmission brake. Run the tractor at idle speed while the speed transmission is in 3'rd gear.

Push on the clutch and count 1-2-3- and try to slowly shift to high range. It should go in nicely with only a 'clunk' from the gears. Any adjustment tighter than this will make it difficult to shift on-the-go.

Try to adjust this accordingly. Remember to break loose the jamb nut before removing the locking pin. They sometimes require a little persuasion.

I have been setting them up this way for quite some time (and follow the order) and it has worked well. Remember to lube all of the shift linkages on top of the transmission from time to time, and you will have a super nice useable tractor.
