Kubota MX5100, 4700 Parts Catalog – Real Parts Data, No Guessing

If you’re rebuilding a loader on a Kubota MX5100, 4700 and you think any parts diagram will do, you’re about to waste time and money. I’ve seen guys order the wrong control valve three times because they used a generic picture instead of the factory book. This is the real deal – 49 pages of OEM part numbers, interchange codes, and country-specific notes straight from Kubota. No aftermarket reprints. No guessing which bolt goes where.

Frame Assembly: Main Frame and Side Frame Parts (Page 3)

Page 3 starts the frame section. You get exploded views of the main frame, side frame, and front guard (MX8190 option). Part numbers like 7J275-55013 for the LH main frame, with quantities and weights listed in pounds. The instructions for parts books on page 2 tell you exactly how to read the columns: Ref No, Part No, Part Name, Q’ty, S.No., I/C, Remarks. Country codes are there – parts that ship with a [CA] or [FR] tag. Don’t skip page 2 unless you want to order a part that won’t fit your serial number range.

Front Attachments: Bucket Options and Boom Parts

Five different buckets are listed: L2276, L2286 (with bolt-on blade option TL1748), L2296, L2236, L2235. The boom and bucket link are separate sections. Each bucket has its own set of part numbers for cutting edges, weldments, and pins. If you need a replacement blade for a L2286, this catalog shows the exact Kubota part number – no cross-referencing needed. The boom section includes all pivot pins and bushings. Useful for a loader that’s wallowed out from years of abuse.

Control Valve: Valve Assembly and Component Parts

Two entries for the control valve: assembly view and component parts breakdown. This is where the Valve section lives. You get the spool, relief valve, and seal kit part numbers. The component parts page lists every O-ring and spring separate. If your loader drifts down, you can order the exact rebuild kit without buying the whole valve body. Look for the REF numbers that match the exploded diagram – saves you from ordering a valve that’s different because of serial number splits.

Hydraulic System: Cylinder and Hose Routing

The Cylinder section covers both boom and bucket cylinders with component parts pages. Cylinder (Boom) and Cylinder (Bucket) each get their own breakdown – rod seals, piston rings, gland nuts. The hydraulic hose section shows routing for the main lines and the outlet block. There’s also a hydraulic tube diagram. If you blow a line and need the exact formed tube, this catalog gives you the part number. No bending your own unless you’re into leaks.

Why a Factory Parts Catalog Beats Aftermarket Printouts

Aftermarket parts catalogs often combine multiple makes or skip the “Remarks” column that tells you a part is EXCEPT [FR]. That means you might order a part that’s fine for Canada but wrong for your US-spec tractor. This OEM catalog came from Kubota itself – part numbers are direct from the factory. The I/C column shows if a part is interchangeable between older and newer serial numbers. NI means no interchange. That kind of detail saves a return trip to the dealer. Related factory documentation includes a Kubota MX4700 MX5100 2009 Workshop Manual”>workshop manual for repair procedures and a Kubota V3300-T-E2B-EPS-1 Parts Catalog – 53-Page OEM Parts Breakdown”>V3300 engine parts catalog if you’re working on the powertrain.

Who Needs This 49-Page Parts Catalog?

Home garage guys who bought a used MX5100 or 4700 with a LA844 loader and need to rebuild it. Farmers who blew a bucket cylinder and want the exact seal kit. Equipment dealers who need to confirm part numbers for customer orders. This is not a service manual – it won’t tell you how to tear down the loader. But if you need the correct part number for a bolt, washer, or hydraulic hose, this is the one source you can trust. Pair it with a Automotive Industry Overview for general context, or check Automotive Industry Overview for background on equipment standards.

Frequently Asked Questions

Does this parts catalog cover the entire MX5100 or 4700 tractor?

No. It covers only the LA844 loader attachment. The frame, hydraulics, valves, and buckets specific to that loader. For the tractor itself, get the chassis parts catalog.

How do I read the part number columns?

Page 2 explains everything. REF No matches the diagram. Part No is the factory number. Q’ty is how many you need. S.No. shows serial number range for fitment. I/C means interchangeable – = works both ways, NI does not. Remarks may say EXCEPT [FR] meaning not for France. That page is worth reading twice – I’ve seen guys order a CA-only part for a US tractor and wonder why it didn’t fit.

Are torque specs included?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities, not assembly torque values. For tightening bolts on the loader, use the factory workshop manual.

Can I use this to order the correct cylinder seal kit?

Yes. The cylinder component parts pages list individual seals, O-rings, and wiper rings. Find the REF number for your cylinder (boom or bucket) and order the part number shown. Just verify your serial number range – Kubota changed seals over production runs.

Stop guessing which part fits your loader. Access the Factory Manual – the genuine Kubota parts catalog with 49 pages of verified OEM data. Every number, every diagram, every country code is from the same source your dealer uses.
