Kubota B6100E-P Parts Catalog – 128-Page OEM Parts Breakdown

I’ve been wrenching for 28 years. Seen more parts counter screw-ups than I care to count. A guy brings in a B6100E-P, needs a valve cover gasket, orders one from a third-party list, and it’s the wrong thickness. That’s time lost, money wasted, customer pissed. This Kubota B6100E-P Parts Catalog puts an end to that. 128 pages of factory exploded diagrams and part numbers. Not some scanned-and-guessed PDF. Straight from Kubota’s own engineering.

You want to know what you’re getting? Look at the table of contents. It’s organized by assembly groups—Crankcase, Cylinder Head, Gear Case, Bearing Case, Breather, Inlet Manifold, Valve Rocker Arm, Head Cover, Camshaft, Piston Crankshaft, Flywheel, Nozzle Holder, Injection Pump, Speed Control Plate, Governor, Dynamo, Clutch, Name Plate, and on through the Transmission. Every single group has its own section with reference numbers and part descriptions. That means when you tear down the engine, you flip to the Piston Crankshaft Group and see exactly which connecting rod matches your serial number.

I don’t trust aftermarket parts books. They redraw the diagrams, sometimes skip a bolt or use a generic fastener. This catalog is the real deal. Each exploded view uses the OEM reference numbers from the factory. The crankcase group diagram on page 1 shows every seal, bearing, and plug. You need a cylinder head gasket? The Cylinder Head Group lists the part number right next to the head. Valve stem seals? Valve Rocker Arm Group, clear as day. No guesswork.

What the Crankcase Group Shows You

Open to the Crankcase Group. You’ll see a numbered diagram with a table underneath. Reference numbers like 017, 019, 022, and so on. Against each reference number is the part number and description. For the B6100E-P, the crankcase itself is a precision casting. If you crack it, you need that exact part number. This catalog gives it to you. Also shows the oil seals, dowel pins, and drain plug washer. Every piece the crankcase needs. No aftermarket catalog I’ve seen lists those dowel pins. This one does.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, accuracy. Kubota’s own engineers created these drawings. The parts are dimensionally correct. Second, completeness. You get every fastener, every gasket, every bushing. Third, traceability. The part numbers match what Kubota dealers stock. Bring this catalog to the dealer, and you hand them the number. They order it. Done. No cross-reference errors. Compare that to a generic online list that says “fits B6100 series” but leaves out the E-P suffix, and you end up with a different transmission shift fork. Save your weekend. Use the factory book.

Transmission and Axle Breakdown: Gears, Shafts, and Seals

The Transmission section is a beast. It includes the Transmission Case Group, Case Cover Group, Axle Case Group, and every shaft group: 1st/4th, 2nd/Reverse, 3rd/5th/PTO. Plus the Differential Group and the Main, Aux., and Rotary Speed Change Groups. If you’re rebuilding a gearbox, you need to know which bearing goes on which shaft. This catalog identifies each gear by tooth count and part number. The Rear Wheel Group for America shows the hub and axle components specific to the US market. There’s even a separate Front Axle Group for America/Canada. That’s the level of detail that saves you from ordering a European-spec axle that doesn’t fit.

Does This Catalog Cover the Hydraulics and Steering?

Yes. There’s a whole Hydraulic System section with Control Valve Group, Oil Pressure Group 1 and 2, plus the Steering Group. If you’re chasing a steering leak, the Steering Group diagram shows the tie rods, knuckles, and seals with part numbers. The Brake Group and Brake Rod Group are there too. That’s 128 pages of every mechanical assembly on the tractor. Automotive Industry Overview might teach you general history, but this catalog teaches you exactly what to order for your B6100E-P.

Short answer: it covers engine, fuel system, cooling, electrical, clutch, transmission, rear axle, brakes, steering, hydraulics, hood/bonnet, chassis, labels, and accessories. Check the PDF bookmarks. They match the printed TOC exactly.

Does this catalog apply to the B6100E-P only?

Yes. It’s specifically for model B6100E-P. Not the B6100D or B6100HST. The part numbers and diagrams are unique to this model.

How are parts grouped in the book?

By assembly group—engine, transmission, steering, etc. Each group has exploded diagrams and a parts table. You look up the group, find the part number, order it.

Can I use this to rebuild the entire engine?

The catalog gives you part numbers for every internal component: pistons, rings, crankshaft, camshaft, valves, bearings, seals. But it’s a parts book, not a service manual. You need the factory service manual for torque specs and procedures. That said, having the right part numbers is half the battle.

What’s the page count?

128 pages. Exactly enough to cover every assembly without fluff.

I’ve been burned by aftermarket parts lists. This catalog is the cure. Stop wasting time and money on wrong parts. Access the Factory Manual and get the real part numbers before you touch the wrench.
