Kubota Kh191Kdg Parts Catalog – Factory OEM Parts Breakdown for Engine and Hydraulic Systems

If you’re rebuilding a Kubota Kh191Kdg Parts Catalog and need the exact part number for the oil pan gasket or the crankshaft seal, you already know the frustration of flipping through aftermarket cross-references that skip serial number breaks. That is why I stock this 360-page factory parts manual in my shop. It is the same document the Kubota dealer uses. No missing pages. No reprints. Just the OEM exploded views and part numbers that match what came off the assembly line.

Engine Section: Crankcase to Cylinder Head – What’s Covered

Start at the bottom end. The CRANKCASE section on page 2 lists the main bearing case, cylinder liners (six of them, part 160 on the explosion), oil pump assembly, and all the O-rings and dowel pins. Page 4 gives you the OIL_PAN breakdown – pan itself, gasket, drain plug, oil filter mount, and dipstick. I have torqued enough oil pan bolts to know that a wrong gasket number means a leak you will chase for hours. This catalog lists the gasket part for serial number breaks like <=65325 and >=65326. That matters.

Crankshaft and Camshaft – Critical Wear Parts

PISTON_ CRANKSHAFT covers the connecting rods, pistons, rings, wrist pins, and the crankshaft itself. For the camshaft, the CAMSHAFT section gives you the gear, key, and thrust plate. If you are rebuilding a Kh191Kdg engine, these are the parts that wear out first. You need the factory part number for the camshaft gear – the aftermarket listings often mix up the tooth count. This manual shows the exact Kubota part, no guessing.

Does This Manual Cover the Hydraulic System?

Yes. About half the book – roughly 180 pages – is dedicated to the hydraulic circuits: gear pumps, drive motors, swivel motors, control valves, spool sections, and all the piping for boom, arm, bucket, dozer, and travel. If you are rebuilding a control valve, the CONTROL VALVE 1 COMPONENT PARTS and CONTROL VALVE 1 SPOOL SECTION explode the valve stack. I have seen technicians order the wrong spool kit because they used a generic manual. This catalog assigns every spool and spring a unique Kubota part number. Worth the price of the book alone.

3 Reasons to Trust OEM Part Numbers

First, every part number is tied to a serial number range printed right next to it – for example, the oil filler cap changed at serial 54894, and Kubota notes that with a symbol. Second, the weights are listed in pounds and kilograms, so you can verify you received the right component when it arrives. Third, the VALVE ROCKER_ ARM and CYLINDER_ HEAD sections include every bolt, washer, and lock nut. No aftermarket catalog cross-references these correctly. For context on why OEM standards matter, see Automotive Industry Overview and Automotive Industry Overview.

Valve Rocker Arm Assembly: Detailed Exploded Views

The VALVE ROCKER_ ARM section shows the rocker shaft, arm, adjusting screw, and push rods. The CYLINDER_HEAD section includes the valves, springs, retainers, and seals. If you are doing a valve job on a Kh191Kdg, you need the part number for the valve stem seal – it is a different rubber compound than automotive seals. This manual gives you the 15221‑33700 O-ring and the 15221‑33610 plug, all indexed by position. No mystery.

No aftermarket guesses. Factory part numbers only.

FAQ – Frequently Asked Questions

Does this manual cover the entire engine?

Yes, from crankcase through cylinder head and valve train.

Are torque specs included for the cylinder head?

This is a parts catalog, not a service manual. It lists part numbers, not torque values. You need the service manual for that.

What is the difference between this and a service manual?

A parts catalog shows exploded diagrams and part numbers for ordering. A service manual gives procedures, torque specs, and tolerances. If you are rebuilding the engine, get both. This catalog is essential to order the correct seals, gaskets, pistons, rings, and bearings. Without it, you risk ordering the wrong parts and wasting time.

How can I verify the part numbers?

The part numbers in this catalog are direct from Kubota’s factory system. Cross-reference them with your machine’s serial number. The manual includes serial number breaks (e.g., <=65325 vs >=65326) so you know exactly which parts fit your machine. That level of detail is missing from aftermarket sources. For example, the oil pan gasket part numbers changed at engine serial number 110857. If you order the wrong one, it won’t seal. I’ve seen that happen. This catalog saves you that headache. Always check the serial number range listed next to each part. The manual shows it clearly. That is why factory documentation is worth the money.
