Branson 5020R, 3520CX, 4020CX, 4520C, 5220C Parts Catalog – Factory Specs for the Workbench

If you’ve ever ordered a part for a 20-series Branson tractor and ended up with something that doesn’t fit, you know the pain. I’ve seen guys spend half a day cross‑referencing aftermarket numbers, only to find out the pump drive gear is off by a tooth. That’s exactly why this Branson 5020R, 3520CX, 4020CX, 4520C, 5220C Parts Catalog exists. It’s 91 pages of factory‑issued part numbers, exploded views, and model‑specific callouts. No guesswork, no aftermarket garbage.

P.S.T. Cylinder and Hydraulic System Parts

You need a P.S.T. cylinder for a 5020R? Page 13 breaks down the entire assembly, complete with seal kits and housing numbers. The hydraulic pump section starts on page 39, and the control valve (page 44) lists every spring and spool separately. When you’re rebuilding a hydraulic circuit, having the exact OEM reference for that relief valve (page 47) saves a return trip to the dealer.

Steering, Axle, and Drivetrain Components

Steering column (page 2), front axle bracket (page 4), and the center pin supporter (page 5) are shown with hardware callouts. The ring gear and differential gear (page 7) are critical if you’re setting up a new ring‑and‑pinion. Page 8 covers the front axle gear case. I’d trust these exploded views over any aftermarket schematic because they match the production line drawings. For related manuals, check the Branson 2910 3510 3820 4220 3110 Parts Catalog – OEM Factory Specs if you work on older Branson models.

Cabin Assembly: 20R Series Cab Parts

The cabin frame (page 76), fender assembly (page 77), door (page 80), and roof (page 83) are each laid out with every bolt, gasket, and latch. Need a side mirror bracket? Page 82. Looking for the A/C duct (page 85) or compressor (page 88)? All there. If you’re repairing a cab that’s been in a collision, this section alone is worth the price. The Branson 3510, 2810, 3520, 4020, 4320 Parts Catalog – Factory OEM covers earlier series, but this 20R/20C catalog is specific for the models listed.

Electrical and Hydraulic Piping Diagrams

Page 56 shows the electrical wiring layout, and pages 51–54 cover the hydraulic piping in four separate views. When you’re tracing a hydraulic leak or adding a remote valve, you need the routing from the factory. The battery (page 57) and switch (page 58) locations are marked. I’ve seen too many guys chase electrical gremlins because they used a generic diagram. This catalog gives you the real harness layout.

Why a Factory Parts Catalog Beats Aftermarket

Aftermarket catalogs often combine model years or skip hardware that doesn’t appear in every revision. This document is scanned from the original Branson publication – the same one dealers use. The part numbers match what you’d get from a Branson dealer. No guessing which washer fits. Page 12 has the front wheel and tire specs; page 34 lists rear tires. The engine sub‑assembly (page 73) is a separate reference. If you’re rebuilding a 5220C or a 4520C, you need the exact part numbers from this catalog. The Branson 00 Series 2012 Operators Manual – Factory Specs & Procedures is a good companion for operating procedures, but for parts, this is the one.

Frequently Asked Questions

Does this catalog include torque specs?

No, it is a parts catalog, not a service manual. Torque values are not listed.

How do I identify the correct part number for my model?

Each page lists model keys (A: 3520CX, B: 4020CX, C: 4520C, D: 4520CX, E: 5220C, F: 5220CX). Look at the top of the parts table. For example, the spring washer on page 3 shows which models use it. If your tractor is a 5020R, cross‑reference with the 5220C column because the chassis is often shared. Always verify by comparing the old part physically if possible, but the catalog will narrow it down to one or two numbers.
