Blue Giant Parts

Blue Giant parts on this page total 194 listings, and about 135 of them are pieces of a hydraulic unit: pistons, U-cups, O-rings, balls, springs, pins and the small hardware that holds a pump together. The rest are air filters, steer wheel assemblies, bearings and a few load wheel kits. The search box at the top of every page takes a part number directly, and each manufacturer has its own page if you'd rather browse by brand.

Most pallet jack hydraulic units are rebuilt a piece at a time, so the first job is working out which Blue Giant unit you have. The listings name it, and that is how this page is organized.

Blue Giant Parts by Type

Hydraulic unit parts lead the range, then air filters with 27 listings and pins with 21. After those come 14 springs, 13 screws and screw plugs, 12 bearings and 10 O-rings. Smaller groups include 9 balls, 8 handle parts, 8 nuts, 7 U-cups, 7 other rings (snap rings, circlips, a locking ring and a quad ring), 7 load wheels and 7 washers. Below those are 6 listings that name a valve, 5 bushings, 5 steer wheels, 5 seal kits, 4 controllers, 3 pistons, 3 bolts and 3 chain parts.

Each of those has a wider page if you want to compare makes. The forklift pins page covers about 900 listings, seals, gaskets and O-rings about 2,650, and wheel bearings about 1,300. For the pump and valve side, hydraulic pumps, valves and cylinders runs to about 3,500.

Picking Your Blue Giant Hydraulic Unit

Three families show up in the listings, and the model names sit at the end of each one. The PT-50 and PT-55 share the same listings, 47 each. The MT-50 has 45. The ROI-5 and ROI-55 are listed together with the MTS 2000, 42 listings in all. Each listing puts the number first, then the part, then the unit, as in "906-0051 U-CUP FOR BLUE GIANT MT-50 HYDRAULIC UNIT."

Once you know your family, the search gets short. For a PT-50 or PT-55, look for a ball (105-734), a spring (104-006) or a valve (797-489). For an MT-50, the parts include a bushing (906-0057), a quad ring (906-0011) and a steer wheel assembly (906-0078-A-ST). The ROI and MTS 2000 listings add a handle pin (117-888), a U-cup (036-099) and several screws and O-rings.

If your unit isn't one of those three, the sections further down cover the other kinds of Blue Giant listing.

Small retaining hardware is easy to overlook when you order, and these listings cover it. The MT-50 range includes circlips (906-0072, 906-0093), roll pins (906-0049, 906-0071) and a short collar screw (906-0033). The PT-50 and PT-55 range has a washer (104-008) and a nut (011-569). Across all three families there are 9 balls, 7 U-cups, 6 plugs and 5 rods, so much of a rebuild list is on this one page.

Reading Blue Giant Part Numbers

The hydraulic unit parts use a short number: three digits, a dash and three more, as in 794-476 for a PT handle frame or 011-569 for a nut. The MT-50 parts are different, with numbers that mostly start 906- and end in four digits, sometimes with a suffix. Search the whole number with its dash, because that is how the listing is written.

Not every listing follows that pattern. "MI026-539" and "BLUE GIANT 026-507-1 CONTROLLER" are written differently, and the air filters carry the filter's own code instead. The listings for "Air Filter CA2592," "FA230PL" and "P530642" are good examples, so match those codes against the filter in your hand.

Filters, Bearings and Wheels

Away from the hydraulic unit, the biggest group is air filters at 27 listings. The codes include CA2592, CA326, CA7456 and CAK5047S. If you can't find yours here, the forklift air filters page holds about 3,100.

Bearings and wheels are a small group, but they show where the range goes beyond pallet jacks. The skid steer bearings include MG307FFH, HVX376RS and 307SZZ10. There's also a "Blue Giant EPJ45 Electric Pallet Jack Load Wheel Kit" and a "Blue Giant Pallet Jack Steer Wheel W/ Bearings." If your jack isn't a Blue Giant, the wider pallet jack parts page holds about 1,700 listings.

Controllers are a small group here, four in all, and one listing names Curtis. The Curtis controller page has about 290 more, which helps when the fault is electrical. For handles and the rest of the body, handles and body parts has about 990 listings, and forklift nuts about 3,200.

What Usually Wears on a Pallet Jack Pump

A jack that won't lift, or sinks under load, often points to the seals and rings in the pump, which means U-cups, O-rings, quad rings and the piston. A handle that feels loose or sloppy points to pins, bushings and the handle frame. These are starting points, not a diagnosis, and a worn part can be a symptom of a different fault, so compare the old part with the listing first.

When a repair needs several of these at once, the pins, springs, clips and rings page and the steering parts page are useful places to cross-check numbers, since they cover other makes too.

Blue Giant Parts FAQ

Are these Blue Giant's own parts?

Mostly not. Treat "FOR BLUE GIANT" as a reference to the unit. The part is an aftermarket replacement built for it, and Blue Giant did not make it.

How do I know if I have a PT, MT or ROI unit?

Check the model on the jack, then match it to the end of the listing. PT-50 and PT-55 are listed together, as are ROI-5, ROI-55 and MTS 2000, while MT-50 stands alone.

Do you list parts for Blue Giant skid steers?

Only a few. Seven listings name skid steer, mostly bearings such as MG307FFH, HVX376RS and 307SZZ10. The rest of the range is for pallet jacks.

Is MRK Sales an established seller?

Yes, and the record is public. Our eBay account, ouroverstock, has been selling since 2004 and carries Top Rated Seller status, 99.9% positive feedback and more than 200,000 items sold.

Where do I send a question about a listing?
