Cub Cadet 420 Parts Catalog

Ordering the wrong part for a 420 utility vehicle costs you time and money. You pull the old bearing, find it’s .63 ID x 1.19 OD, but the aftermarket listing says something else. Then you’re stuck waiting another week. This 78-page factory parts catalog from Cub Cadet puts the exact part numbers and hardware specs in your hands.

78 Pages of Factory Parts Breakdown

Every page in this catalog comes straight from Cub Cadet’s engineering files. No reprints, no third-party transcription errors. You get exploded diagrams with reference numbers that match the parts list. The front suspension axle section alone covers right and left axle assemblies, steering knuckles, shock absorbers, bushings, bearings, and grease fittings. Page 2 lists the exact part numbers for the left-front axle assembly (607-04005) and right-front (607-04004), along with every hex screw, lock nut, and spacer. That’s the level of detail you need when ordering components for a 4X2 work vehicle.

Cub Cadet 420 Parts Catalog: What’s Inside

Front axle, bed assembly, bed lift, steering, brakes – the catalog organizes each system into its own section. The bed section on page 4 gives you the utility bed assembly (607-04021), tailgate assembly, lift cables, compression springs, and all the small hardware like cotter pins and washers. You also get the bed lift section with cable part numbers and mounting brackets. Each item has a reference number, a factory part number, the quantity needed, and a serviceability code (S/P/F) that tells you if the part is serviceable, a production part, or a field replacement.

Front Suspension Axle: Part Numbers and Specs

Working on the front end of a 420? You need the right steering knuckle (RH: 723-0618, LH: 723-0619), the correct shock absorber (732-04069 with 2.9-inch stroke), and the proper fasteners. The catalog shows M10-1.25 x 65mm hex screws, 5/8-11 x 11.13 grade 5 hex screws, and nylon lock nuts. If you’ve ever tried to match a metric bolt by eye, you know why a printed parts list saves the day. Every thread pitch and length is printed – no guessing.

Does This Catalog Cover the Bed Assembly?

Yes, and it covers it completely. The bed section on page 4 includes the tailgate assembly, bumper extension suspension parts, lift handle, and the cable that raises the bed. You’ll find the shoulder spacer (.625 OD x .324 ID) and the flat washers with specific ID/OD/thickness. If your bed won’t latch or the lift cable snapped, the part number is right there. Pair this catalog with a service manual for removal and installation steps – the parts list alone won’t teach you procedure, but it will keep you from ordering the wrong cable.

Torque Specs and Hardware: What You Get

This catalog doesn’t give torque values directly – that’s a service manual job. But it lists hardware grades and thread sizes. A grade 5 hex screw with 1/2-13 thread has a known torque spec range. The grease fitting (737-04006) and bearing (741-0758) with .63 ID x 1.19 OD let you source correct replacements. When you see a hex screw listed as 710-04012 (1/2-13 x 6.50, Gr5), you know exactly what to order and what torque spec to look up. That’s more than aftermarket lists give you – they often skip the grade and length.

Why OEM Parts Catalogs Beat Aftermarket Lists

Aftermarket parts lists are compiled from observations and often have errors. This catalog is the original Cub Cadet documentation – the same one dealers use. Every part number cross-references to an engineering drawing. If you’ve ever received a wrong bushing because a third-party site listed the wrong ID, you understand the value. The Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs and Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns follow the same standard. For a complete lineup, check Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown. The Automotive Industry Overview relies on standardized part numbering, and this catalog uses it. Automotive Industry Overview conventions apply here – you get the real deal.

Get the Right Components for Your 420

You pay for your tools, you pay for your time. A wrong part order wastes both. This catalog pays for itself on the first correct order. Stop guessing part numbers. Access the Factory Manual and get the correct components for your Cub Cadet 420.

Does this catalog include torque specifications?

No. It lists hardware sizes and grades, which let you look up the correct torque in a service manual.

Can I use this parts catalog to rebuild the entire 420?

Depends on what you call rebuild. This catalog gives you every part number for the front suspension, bed, bed lift, and other assemblies. You can order every nut, bolt, bearing, bushing, and spacer. But a parts catalog is not a repair manual – it doesn’t tell you the order to take things apart or the specialty tools needed. If you’re doing a full teardown, pair this with the factory service manual. The parts catalog saves you from guessing which hex screw goes where. For example, the front axle uses M10-1.25 x 65mm and 50mm screws, and the bed uses 1/2-13 x 2.50 GR5 hex screws. You won’t find that level of detail in a generic list.
