Cub Cadet 108 Parts Catalog

Ordering parts for a Cub Cadet 108 without the factory breakdown is how you end up with the wrong air cleaner housing and a box of bolts that don’t fit. I’ve watched guys spend two hours on the phone returning parts because they trusted a generic website instead of the OEM listing. This Parts Catalog runs 82 pages of factory-sourced diagrams and part numbers. Page 2 shows the air cleaner assembly with every nut, seal, and filter element identified by IH and KH prefix part numbers. That’s the difference between a one-order job and a parts run.

Brake Caliper Assembly: OEM Part Numbers for Your 108

Page 5 breaks down the brake caliper into 21 separate ref numbers. You get the casting, the pads, the hardware, and both Ausco and H-H Products variants. If you’re rebuilding the hydrostatic drive brakes on a 108, you need those specific part numbers. Aftermarket catalogs frequently skip the spring pack or give you the wrong caliper piston. The factory catalog gives you the original IH- prefixed numbers. I’ve used these to cross-reference NLA items with aftermarket suppliers—saved a whole billing cycle.

Air Cleaner & Extension – What You Need to Know

The air cleaner section on page 1-2 lists the base, seal, filter element, elbow, clamp, and wing nut. Part number KH-237424 for the base, KH-237423 for the seal. Notice the “/S” and “/P” flags—those mark service and production parts. That matters when you’re ordering a filter element (IH-385168-R2) that’s a service replacement. Skip that detail and you might get a different shape element that doesn’t seal. The exploded drawing shows the orientation of the elbow and clamp. I’ve seen too many guys bolt on the wrong air cleaner housing because they eyeballed it.

3 Key Systems Documented in This Parts Catalog

Battery holder, brake caliper, and air cleaner are just the first three systems covered. The battery holder section (page 3-4) gives you the hold-down bolt (IH-544149-R1) and the wing nut (712-3044). The brake section includes both the H-H Products and Ausco caliper variants. Air cleaner covers the full intake path from filter to carb elbow. Each system has its own exploded view with ref numbers, part numbers, quantities, and description. That’s the level of detail you need when a single missing spring stops the whole job.

Cub Cadet 108 Parts Catalog: What’s Inside the 82 Pages

Every page follows the same format: a numbered diagram on the left (or top) and a table on the right (or bottom) with ref#, part number, qty, description, and service/production flags. Page 5 for the brake caliper shows 21 items. Page 2 for the air cleaner shows 7 items. No generic text—just the data you need to order the right part. The catalog is organized by assembly groups: engine, transmission, steering, electrical, frame, etc. This is an OEM factory document, not a third-party compilation. The part numbers are the original International Harvester and Kohler numbers that dealers still use today.

Does This Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. You won’t find torque values, fluid capacities, or adjustment procedures. What you get is the exact part number for every nut, bolt, gasket, and seal on the machine. For torque specs, you need the factory service manual. But without this catalog, you’ll order the wrong caliper kit because the aftermarket listing says “fits 108” and it doesn’t match the Ausco vs. H-H Products design. I’ve lived that headache.

Get the Right Parts the First Time

Comb through the battery holder clamp assembly on page 3—the catalog shows the hold-down bolt and wing nut, but the clamp itself requires ordering the battery strap assembly (703-0017). That distinction saves you a return. The same logic applies to every assembly in the 82 pages. Experienced mechanics keep this catalog on the bench to verify part numbers before calling the dealer. Beginners use it to learn how the tractor is assembled. Either way, you stop guessing and start ordering factory-correct parts.

Frequently Asked Questions

Is this manual suitable for a complete restoration of a Cub Cadet 108?

Yes, it lists every factory part with OEM numbers.

What if a part number is marked ‘NLA’ in the catalog?

NLA means no longer available from the original manufacturer. You can cross-reference the OEM part number with aftermarket suppliers or used parts dealers. Some NLA items have superseding part numbers listed in later revisions—this catalog doesn’t include those, but you can check with a Cub Cadet dealer (call 606-678-9623 as noted on every page) or search online forums for known cross-references. The exploded diagram helps you identify the exact component so you can find a compatible replacement even if the original number is obsolete.

Access the Factory Manual and start ordering parts that actually fit. The 82 pages are all original OEM—no reprints, no aftermarket edits. Put this catalog on your workbench next to your torque wrench and save yourself the trip to the parts counter.
