MDI Yutani MD240C 1991 Parts Catalog – You Need the Right Numbers

If you’re tearing down an MDI Yutani MD240C 1991 Parts Catalog machine and you order a bucket edge off memory or a cross-reference website, you’re going to eat the return shipping. I’ve seen guys hold up a job for three days because they grabbed the wrong pin – then blame the machine. This 434-page OEM parts catalog from 1991 is what the dealer parts counter uses. Printed in May 1991 by Kobelco Construction Machinery America, it’s the original source for every fastener, bushing, and cutter on your MD240C.

What This 434-Page Parts Catalog Covers

Open it and you see a full machine breakdown. The table of contents isn’t listed in the file, but the structure is classic factory: each assembly gets its own exploded diagram and a table listing part number, description, and quantity. The serial number range on page 1 is MD240C LLU0301~0600 – if your machine falls in that band, every part listed applies. If it doesn’t, you need the right supplement. This is not a generic aftermarket compilation; it’s the exact document Kobelco sent to distributors.

Bucket Assembly Breakdown on Page 4

Flip to page 4 and you get the bucket assembly for YPU00301~. The diagram shows item numbers that map to a table on page 5: bucket, cutting edge, adapters, points, locking pins, side cutters, plow bolts, bushings, O-rings, capscrews, lockwashers, pins, shims, and spring pins. Item 3-3 and 3-4 are plow bolts and nuts marked “not available through Kobelco America Inc., please procure locally.” That’s the kind of real-world caveat that saves you a phone call. The part numbers are Kobelco numbers – 24100N6418F1 for the bucket assembly, 2412T881D1 for the cutting edge. No guessing.

Audience: Who Needs This on Their Workbench?

Home garage enthusiasts who are restoring an old MD240C will find the exploded views invaluable – you can see exactly how the side cutters stack. Professional mechanics rebuilding a machine for a customer need the correct shim thicknesses: the table lists shim 1.0 mm (item 13, 2418T12260D1) and shim 3.2 mm (item 12, 2418T12260D2) with quantities. Order the wrong shim pack and your bucket alignment is off. Workshop owners who keep a library of factory documentation for their techs cut down on repair delays and liability – you hand this to a junior tech and he can pull the right parts without asking you every time.

Source Authenticity: OEM vs Aftermarket Parts Catalogs

Aftermarket parts catalogs often re-use old illustrations and change the part numbers to fit their inventory. They might swap a Grade 8 bolt for a Grade 5 and not tell you. The automotive industry relies on accurate documentation to avoid recalls – Automotive Industry Overview shows how critical spec integrity is. This catalog is an original Kobelco print. Book code KCMLLUM90S001PM. Printed in USA. No reprint house touched it. If you need to verify a part supersession, you call the number on the parts bulletin inserted in front – that’s real factory communication.

3 Reasons to Use Factory Parts Documentation

1. Correct supersessions. The PID (part identification) includes revisions – the catalog is dated May 1991, but the parts bulletin on page 3 from March 1992 adds bucket assembly breakdowns for SK120, SK200, SK220. That bulletin is included here. You get the updates, not just the original print.
2. Accurate illustrations. Exploded views show exact orientation of bushings, O-rings, and locking pins. The bucket assembly diagram on page 4 clearly shows where the spring pin (item 14) goes – miss that and the pin walks out.
3. Safety-critical identification. The cutting edge and side cutters are wear items that affect machine stability. Using the wrong point (item 2-1, X220) can cause breakout failure. The catalog gives you the OEM spec – no guesswork.

Related Manuals for the MD240C

If you’re working on an older machine, check the MDI YUTANI MD240B 1989 Parts Catalog – it covers the previous model with different serial breaks. For service procedures like engine rebuilds, the MDI Yutani MD200B Shop Manual has torque specs and disassembly steps. Need fastener torque tables for the bucket? The Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide isn’t related to your machine but shows how Kohler and Kobelco used similar bolt grades – still, stick with your OEM catalog.

Frequently Asked Questions

Does this catalog include service procedures like torque specs?

No. This is a parts catalog – it lists part numbers and quantities, not service steps. For torque values you need the shop manual.

Can I use this to order parts directly from Kobelco?

Yes. The part numbers are Kobelco factory numbers. If you call a Kobelco distributor with the numbers from this catalog, they will be able to pull the parts. The printed-in-U.S.A. stamp tells you it’s an official document.

Are the part numbers still current for 2025?

Some numbers may have superseded. The catalog itself is from 1991, but Kobelco maintains a supersession history. You’ll need to cross-reference the 1991 number with the dealer’s current system. The catalog gives you the original base number – that’s the starting point.

How do I read the bucket assembly table on page 5?

The table lists item number (from diagram), part number, description, and quantity per assembly. For example, item 1-17 is cutting edge 2412T881D1, quantity 1. Items with a dash (like 1-18) are sub-components of the main assembly. The footnote tells you items 3-3 and 3-4 must be sourced locally – that’s critical.

The industry is full of aftermarket garbage – don’t trust a parts list from a forum. Automotive Industry Overview standardizes how original equipment manufacturers document their products. This catalog follows that standard. Access the Factory Manual and keep it on your tablet next to the machine – you’ll save yourself the headache of wrong parts.
