Mytractorforum B6100HST-D Parts Catalog – What You Get

If you have ever tried ordering a part for a tractor that came with a hand-drawn sketch and a prayer, you already know why this catalog exists. The Mytractorforum B6100HST-D Parts Catalog is 138 pages of factory-origin part numbers and exploded views, not some reseller’s best guess. I have been wrenching for 28 years and I have seen more parts-bin rejects than most people have seen tractors. Aftermarket catalogs are trash—wrong numbers, missing updates, no reference to superseded parts. This one comes from Mytractorforum, which at least compiled the original factory data instead of copying somebody else’s mistakes.

What This Parts Catalog Covers

The TOC alone runs over seventy line items. You get the full Crankcase and Cylinder Head sections with every bolt, gasket, and plug listed by part number. Valve Rocker Arm, Camshaft, Piston Crankshaft – all indexed. There is a separate Transmission group that includes the Hydrostatic Transmission (that’s the HST in the model name), plus gear shafts, differential, and brake components. The manual breaks the tractor into logical groups: Engine, Fuel System, Cooling, Electrical, Clutch, Transmission, Steering, Hydraulic System, and Hood/Chassis. Each group has its own exploded diagram with callouts. That means you can point to a broken bracket or a leaking seal and find the exact factory part number in minutes, not hours of scrolling through generic sites.

Cylinder Head and Valve Train: Exploded Views

The Cylinder Head section (Page 3 reference: 01T002) shows every valve, guide, spring, and retainer with part numbers. The Valve Rocker Arm assembly is separate (01T007). If you need to rebuild the top end, you get the complete breakdown: rocker shaft, arms, adjusting screws, locknuts. No guessing which aftermarket kit matches your serial number. The manual also covers the Breather and Inlet Manifold – small details that cause big headaches when the wrong gasket shows up.

Camshaft and Crankshaft: Ordering the Right Parts

Camshaft (01T009) and Piston Crankshaft (01T010) are two of the most expensive parts to swap. The catalog shows the camshaft itself, the gear, key, and thrust plate. The crankshaft assembly includes the piston, rings, wrist pin, connecting rod, and bearing shells. Each part has its own factory number. No cross-referencing a chart from 1987 – this is the same data the dealer looked up before dealers got replaced by online parts portals. The Flywheel section (01T011) includes the ring gear and bolts. Torque values? That is a service manual job. This catalog is for ordering, not assembling. But if you order the right parts the first time, you avoid the trip to the parts counter.

138 Pages of Factory Part Numbers – Transmission and Beyond

The Transmission section alone takes up multiple pages: Transmission Case (01T024), Case Cover, Axle Case, 1st/4th Shaft, 2nd Shaft/Front Wheel Shaft, 3rd/5th/PTO Shaft. Each shaft assembly is drawn with every gear, bearing, snap ring, and seal. The Differential (01T032) and Aux. Speed Change (01T033) are also included. For the HST model, the Hydrostatic Transmission (01T037) has its own page with the pump, motor, and all associated plumbing. The Hydraulic System sections (HYDRAULICS 1 & 2) show the control valve, hydraulic pipe, and 3-point linkage parts. That is the difference between buying a $200 control valve that fits and a $50 one that leaks on day one.

Why a Factory Parts Catalog Beats Aftermarket Lists

Aftermarket parts catalogs are built from marketing, not engineering. They combine multiple model years into one lump, skip supersessions, and often use generic descriptions like “seal kit” with no reference to the original part number. This catalog is a direct scan of the factory breakdown – each page has the model stamp (B6100HST-D) and the reference code (e.g., 01T001 for Crankcase). You can verify the part number against the dealer system. If you are working on a tractor built before 1990, you know that OEM documentation is the only reliable source. I have had enough bad aftermarket parts to fill a dumpster. This catalog cuts that risk.

You also get the ALL PRODUCT INDEX on page 2 of the PDF, which lists every subsystem with its corresponding book reference. That index alone saves you twenty minutes of flipping pages. Need the Starter? Look up 01T022. Dynamo? 01T016 or 01T021. The index covers everything from the Oil Pressure Pump to the Front Axle Case [DP] and 3-Point Linkage. For farmers and tractor owners who do their own maintenance, this is the difference between a Saturday job and a two-week wait for the wrong part to arrive.

I have been using these catalogs for years. They save time, they save money, and they save the frustration of opening a box and finding a part that does not match your exploded view. If you own a B6100HST-D or work on them, you want this on your hard drive and on your shop tablet.

Frequently Asked Questions

Does this parts catalog include assembly torque specs?

No. This is a parts catalog, not a service manual. Torque values are in the factory repair manual.

How do I find the exact part number for my B6100HST-D transmission shaft?

Open the PDF to the Transmission section (book references 01T029-01T031). Each shaft assembly lists the part number for the shaft itself, every gear, bearing, snap ring, and seal. The exploded diagram shows the assembly order, and the part number is right next to the callout. If your tractor has a serial number prefix, cross-check against the index – but for the HST-D model this catalog is complete. I have used it to order a 2nd shaft assembly and the parts matched perfectly.

Access the Factory Manual – it is 138 pages of OEM data that belongs on every B6100HST-D owner’s bench. No reprints, no aftermarket guesswork, just the factory part numbers you need.
