O&K TB098 Parts Catalog – 188 Pages of Factory Part Numbers

If you’ve ever ordered a replacement part for a loader and ended up with the wrong piece because the aftermarket catalog used a generic photo, you know the headache. This O&K TB098 Parts Catalog fixes that. It’s the same book the dealer service desk pulls out when you call. 188 pages, factory-issued, covering Serial No. 19-2428 thru 19-2468 and 19-2601 & Higher for the Model 1900 Loader. No vague silhouettes. You get exploded views and a straight part number for every bolt, seal, and valve.

Parts Breakdown: From Accelerator Pedal to Bucket Teeth

The Table of Contents lists 60+ assemblies. Need the accelerator pedal and linkage? Pages 36-37 show the GM setup. Bucket assembly is pages 20-21. Bucket teeth? Page 25. Counterweight and axle cradle share pages 22-23. Every section includes the part number, description, and quantity. The manual uses abbreviations like AIR (as required) and N.S.S. (not serviced separately). That saves you from ordering a seal that only comes with the whole pump housing.

Wiring and Electrical: Find the Alternator and Back-Up Horn

Battery and wiring diagrams live on pages 48-50. Alternator is in that same section. The back-up horn is page 51. If you’re chasing a short or replacing a harness, this catalog gives you the factory wire colors and connector part numbers. Aftermarket wiring diagrams often skip the real connector—this one doesn’t. Check the O&K L45, 4500Z 1990 Parts Catalog – Parts Manual TB126 for similar detail on other models.

Brake Valve and Controls: Safety First

The Brake section covers the brake head assembly (pages 120-121), the parking brake assembly (page 100), and the Brake Valve (pages 108-109B). Brake controls and lines are pages 106-107C. If you need the clutch cut-out switch or system, those are pages 106-107C and 110 respectively. One wrong part on a brake system can cost you more than time—it’s a liability. Use the factory specs to get the correct spring, seal, or valve cartridge. For reference, the Automotive Industry Overview notes why original documentation matters for heavy equipment.

Hydraulic System: Piping, Valves, and Cylinders

Accessory hydraulic piping (3 spool) is pages 55A-55B. The cushion valve is page 65. Main Valve control assemblies split into 2-spool (pages 60-60A) and 3-spool (pages 60B-61). The control valve assemblies themselves are pages 62-62B and 63-63C. Bucket cylinder and lift cylinder assemblies are pages 58 and 59. This catalog shows every O-ring, port, and fitting. Cross-reference with the O&K L3000 Parts Catalog – Factory OEM Manual (236 Pages) if you run a mixed fleet.

Engine and Drivetrain: Air Cleaner to Torque Converter

Air cleaner (GM) on page 39, air intake system on pages 40-41. The torque converter assembly runs pages 82-850. Clutch groups (forward, 2nd & reverse, 3rd, low) are pages 90-95. Transmission control valve is pages 96-97. 188 pages cover it all—front and rear axle assemblies, steering column, cab enclosed, bucket leveler. If the machine is a TB098 with a GM engine, you need this book.

Why Factory OEM Documentation Matters

Aftermarket catalogs re-draw parts to avoid copyright—then they miss a critical dimension or use a generic bolt that doesn’t fit. This is a direct O&K print. The part numbers match the factory inventory system. No guesswork. The manual even includes a blank page for recording your machine serial number and transmission/converter part numbers. That’s detail you won’t find in a third-party scan. For another reliable source, the Automotive Industry Overview explains the value of standardization in heavy equipment parts.

FAQ

Does this catalog include step-by-step repair instructions?

No. This is a parts catalog—exploded diagrams and part numbers only. You need the service manual for procedures.

I have a TB098 with serial number 19-2500. Which serial range applies?

Your machine falls between serial 19-2428 thru 19-2468 and 19-2601 & Higher. The manual covers both ranges but verify your specific serial against the parts callouts. Some components changed between those production batches. Ordering with the exact serial avoids returns. If you need a second opinion, check the O&K L2500 Parts Catalog – Factory Specs for Part Ordering for similar range coverage.
