Kubota D850-BWS-1 1982 Parts Catalog

I’ve been twisting wrenches for 28 years. When a Kubota D850-BWS-1 1982 Parts Catalog is what you need to track down a specific piston ring or a water pump seal, aftermarket diagrams don’t cut it. This 84-page factory catalog from Kubota, dated April 1982, gives you the exploded view of every assembly – from the crankcase to the air cleaner. No guesswork. You match the code number in the manual to the part you order. That’s how you keep a rebuild moving.

Crankcase Group and Cylinder Head: Assembly Breakdown

The manual opens with the crankcase group (page 1), then moves to the oil pan, and right into the cylinder head group on page 7. The cylinder head section shows the head casting, valves, springs, rocker arm assembly, and injector location. Each part has a reference number and a code number. If you need a valve guide, you look up the code – no need to measure three times and hope. The serial number column tells you which head casting fits your engine’s serial range. That detail alone saves you from ordering a part that’s been superseded.

84 Pages of Factory Part Numbers

From page 1 to page 73, this catalog covers every group: crankcase, oil pan, cylinder head, gear case, main bearing case, head cover, inlet manifold, valve rocker arm, camshaft, engine stop lever, piston and crankshaft, flywheel, nozzle holder, speed control plate, governor, water flange, fuel camshaft, dynamo, water pump, attached parts groups, name plate, injection pump, nozzle holder, starter, dynamo again, and air cleaner. The numerical index on page 75 lets you cross-reference any part code back to its page. That’s 84 pages of factory-verified part numbers.

Why an OEM Parts Catalog Beats Aftermarket Diagrams

Aftermarket parts lists often show a generic diagram with one part number that supposedly fits all serial numbers. This Kubota catalog has a “SERIAL NUMBER” column that breaks down which part applies to which engine serial range. It also marks changes with A (new part), B (shape change), and C (other changes). Aftermarket catalogs skip those details. You end up with a gasket that doesn’t match the thickness. For context on why OEM documentation sets the standard, see Automotive Industry Overview.

Order Parts by Code Number – Not Guesswork

Look at the instruction page (page 2). Parts marked “Order by REF. No.” or “NON SALE” in the CODE No. column are not sold separately. You either source them locally or they come as part of an assembly. The circled numbers in the REMARKS column indicate reference numbers included in the assembly. Order the assembly, and those reference parts are included. This saves you from buying duplicate parts and helps you understand what you can actually order as a single piece. No frustration at the parts counter.

Kubota D850-BWS-1 1982 Parts Catalog: Every Group Covered

The catalog walks you through the governor group, fuel camshaft, injection pump, nozzle holder, starter, and dynamo. Design features follow industry-wide practices, as discussed in Automotive Industry Overview. Each group has its own page range with clear exploded diagrams. If you need to rebuild the injection pump, the parts breakdown on page 61 shows every component with its code. Same for the air cleaner on page 73.

That’s the difference between a job done and a job done twice.

Frequently Asked Questions

Does this catalog include torque specifications?

No, this is a parts catalog, not a service manual. Torque specs are not included.

Can I use this to rebuild the entire engine?

You can use it to identify every part for a complete rebuild, but you’ll need the service manual for assembly procedures. The catalog shows you exactly which part to order.

How are parts designated when they are not sold separately?

When a part is marked “Order by REF. No.” or “NON SALE” in the CODE No. column, it means Kubota does not sell that part individually. It must be procured locally or it is included in an assembly. The circled numbers in the REMARKS column indicate reference numbers that are part of an assembly. So if you order the assembly, those reference parts are included. This prevents ordering duplicate parts and helps you understand which items are not available separately.

Is this the same as a service manual?

No. A service manual has repair procedures; this catalog has part numbers and exploded views.
