Hy Trak 4000 Lb Mast, 5000 Lb Mast, 6000 Lb Mast, 8000 Lb Mast, 10,000 Lb Mast 1990 Parts Catalog

You’ve got a lift cylinder that won’t seal, a carriage that wobbles, or a fork that’s been bent since last Tuesday. You pull the part off, call the dealer, and they ask “What’s the serial number? Which mast stage? Two-stage see-thru or three-stage?” And you’re left staring at a pile of steel with no idea which bushing goes where. That’s where this Hy Trak 4000 Lb Mast, 5000 Lb Mast, 6000 Lb Mast, 8000 Lb Mast, 10,000 Lb Mast 1990 Parts Catalog fixes the problem. It’s the factory book – not a third-party guess. 353 pages of exploded views, part numbers, and the exact revision that came off the assembly line in 1990. No reprints, no copied diagrams that lost resolution. Just the OEM spec you need to order the right piece the first time.

What This 353-Page Parts Catalog Actually Covers

Thirteen sections split by capacity and mast type. Section 1 goes through the 4 & 5000 Lb 2-Stage See-Thru Mast with 10‑, 12‑, 14‑, and 16‑foot heights. Each height has its own lift cylinder assembly on separate pages – starting at page 1-1 for the 10-ft mast right through 1-21 for the 16-ft cylinder. Section 2 covers the same capacities in a 3‑Stage See‑Thru version. Section 3 drops into the 6000 Lb Mast 2‑Stage, and Section 4 does the 3‑Stage. If you run a poultry or specialty operation, Section 5 is the 7200 Lb 3‑Stage See‑Thru Poultry Mast – a niche that aftermarket books always miss.

13 Sections Divided by Mast Capacity and Type

Section 6 and 7 handle the 8000 Lb Mast in 2‑Stage and 3‑Stage configurations. Section 8 gives you the 10,000 Lb Mast 2‑Stage See‑Thru. Then Sections 9 through 11 cover carriages, forks, and optional equipment – the stuff that bolts onto the mast but never seems to have a clear part number. Two special sections at the end: Section 12 for a standard (non see‑thru) 10,000 Lb 2‑Stage mast, and Section 13 for a 12,000 Lb 2‑Stage standard mast. If your machine has a standard mast instead of the high‑visibility version, those sections keep you from ordering the wrong inner rail.

The Difference Between OEM Parts Drawings and Aftermarket Copies

Aftermarket catalogs redraw the exploded views, combine multiple revisions into one image, and often drop callout numbers for fasteners that look the same but have different grades. This Parts Catalog is a direct scan of the 1990 Hy‑Trak release. The drawings are original, the part numbers match the factory numbering system, and the notes column tells you if a part superseded to a new revision. For example, the 10Ft. Mast (High-Visibility) on page 1-1 includes the carriage assembly reference – you flip to the Carriage section (Section 9) and see exactly which faceplate and side‑shift cylinder fits. No guessing which weldment matches your serial number.

Section 8: 10,000 Lb. 2-Stage See-Thru Mast – What You Get

Page layout is straightforward: a numbered exploded view on the left, a parts list with description, part number, and quantity on the right. Lift chains, anchor pins, wear strips, and limit switch brackets all have their own callouts. Have a shredder in the lift cylinder packing? The 10K mast lift cylinder is listed under its own sub‑heading. Compare that to online parts lookup tools where you type “mast seal” and get ten ambiguous results – this book gives you the exact OEM seal part number. Pair it with the companion Hy Trak 642B 644 842B 844 1997 Parts Catalog OEM Specs if you need newer model coverage, or the Hy Trak 1042B, 1242B 1998 Parts Catalog – OEM Factory Specs for later series. For older ag equipment, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide follows the same no‑nonsense format.

Carriages, Forks, and Optional Equipment – Don’t Guess the Mount

Section 9 (Carriages) shows the hook‑type and pin‑type carriage assemblies. Section 10 lists forks by capacity and length – crucial when you’re replacing a single fork and need the exact taper. Section 11 covers optional equipment like side‑shifters, fork positioners, and hose reels. If you’re retrofitting a side‑shift onto a 6,000‑lb mast, the optional equipment section tells you the bracket kit part number and any necessary modifications to the carriage hook plate. That’s information you won’t find in a generic hydraulic parts catalog.

Frequently Asked Questions

Does this manual cover the 7200 Lb poultry mast?

Yes – Section 5 is the 7200 Lb 3-Stage See-Thru Poultry Mast, complete with exploded views and part numbers.

Are the part numbers still current for ordering from a dealer?

Some numbers may have superseded over 30 years, but this catalog gives you the original factory reference. When you call Hy‑Trak or any parts house, you give them the number from this book, and they cross‑reference it to the latest revision. Without this catalog, you’re describing a part by shape and hoping they guess right. With it, you hand them the exact 7‑digit code and get the correct part shipped. I’ve used these old factory books a hundred times in my shop – they save you from ordering a 6‑inch cylinder when you needed an 8‑inch one, and that alone pays for the manual.

Every time I see a tech try to rebuild a mast without the factory parts drawing, I watch them waste an hour measuring and guessing. This Hy Trak 4000 Lb Mast, 5000 Lb Mast, 6000 Lb Mast, 8000 Lb Mast, 10,000 Lb Mast 1990 Parts Catalog kills that guesswork. Access the Factory Manual and keep it on your tablet or print the section you need. Your forklift will thank you, and your parts bill will be lower.
