Case 108, 110, 118 Parts Catalog

Look, I’ve been under tractors longer than most of you have been driving them. Nothing kills a Saturday rebuild faster than bolting up the wrong cylinder because you trusted a third-party part number. This is the factory Case 108, 110, 118 Parts Catalog—38 pages of exploded-view drawings with genuine Case part numbers. No reprints, no aftermarket guessing. If you are working on a Case compact tractor from the 108, 110, or 118 series, this is the only paper you should be holding.

Indexes and Exploded Views – How to Find Your Part

This catalog opens with an alphabetical index to locate major groups, and a numerical index at the back to cross-reference part numbers to pages. Page 1 explains the layout: every illustration is an exploded view that shows parts in their normal relationship. Reference numbers in the drawings match the reference-number column in the parts list. You get the part number, description, and quantity required. If you have ever wasted an hour hunting for a cotter pin that should have been listed next to the cylinder, you will appreciate this setup. The indented description system tells you which parts belong to which sub-assembly. That is critical when ordering for a steering cylinder rebuild or a rear-steering socket replacement.

Serial Number Breaks: Why They Matter

These tractors have engine model splits. The 108 and 118 tractors used a C20123 engine before serial number 9747274, and a C26661 after. The 110 tractor uses engine model C26662. The catalog lists those breaks in the description column. If you ignore serial numbers, you will order the wrong socket assembly or plug. For example, the rear-steering cylinder assembly (part A 55159) may fit one serial range but not another. This is the kind of detail aftermarket manuals omit. Do not guess. Use the factory data.

Ordering Parts Without Headaches

Page 1 also states plainly: orders must specify correct part number, full description, quantity required, machine model and engine model, machine and engine serial numbers, method of shipment, and shipping address. That is not optional. When you call a dealer with that info, you get the part. Without it, you get put on hold. This catalog gives you everything you need to write a clean order. The terms “Right Hand” and “Left Hand” are defined as viewed from the operator’s seat—so you don’t order a left-hand steering arm when you need the right.

Changes and Revised Pages – Stay Current

Case issues revised pages when the machine changes. The catalog tells you to insert the new pages immediately and discard the old ones. Failure to do so leads to confusion—and that costs you money. This is a living document, not a one-time print. The page numbers stay the same, but the issue number and date advance. If you download this factory PDF, you get the latest revision available from AutoRepairManuals.

38 Pages – What You Actually Get

Every page in this catalog is a parts list with illustrations. There are no torque specs, no service procedures, no wiring diagrams. If you need to rebuild a hydrostatic pump, this is not the manual for that. But if you need the correct part number for a rear-cylinder socket assembly (A 56208), the adjusting plug (A 55956), the socket ball seat (G 45175), or even the cotter pin (132-104), this is where you find it. The manual covers all three models: 108, 110, and 118. It is a strict Parts Catalog—nothing more, nothing less. And that is exactly what you need when you are ordering over the counter or online.

Does this Parts Catalog include torque specifications for head bolts or fluid capacities?

No. This is a parts identification catalog only. No torque values, no service steps, no capacities. You need the separate factory service manual for that data.

How do I locate a part if I only have the old part number?

Use the numerical index at the back of the catalog. It lists all part numbers in ascending order with the page number. For example, part A 55889 (ball stud) appears on the rear-steering page. If the number is not in the index, the part may have been superseded—check the latest revision pages. The catalog covers only models 108, 110, and 118; if your tractor has a different model number, this manual won’t help. The alphabetical index in the front also groups assemblies like “Engine” or “Steering” if you want to browse. Keep your machine and engine serial numbers handy—the catalog references them in the description column to ensure you get the correct sub-assembly for your specific tractor build. Without the serial numbers, you risk ordering a cylinder that doesn’t match your steering geometry or an engine harness that won’t plug in.
