Bishamon Parts

Bishamon parts on this page come down to one machine. Of the 109 listings, 104 name the BS-55 pallet jack, one writes the same model as BS55, and four name no model at all. Most of the page is the inside of the hydraulic unit and the frame around it, from O-rings and snap rings to load rollers and bearings. A listing worded "FOR BISHAMON" is a part made to fit a Bishamon jack, not a part made by Bishamon, and the number is there so you can line it up with the one you've pulled off.

If you know the number on the old part, search it. If you only know which end of the jack is failing, the next section shows how the listings are sorted.

Hydraulic Unit or Frame

Almost every BS-55 listing ends with one of two phrases. About 58 end in "HYDRAULIC UNIT," like "52103653 SPRING FOR BISHAMON BS-55 HYDRAULIC UNIT," and about 44 end in "FRAME," like "81036205 BEARING FOR BISHAMON BS-55 FRAME." The first group holds the small internals, such as springs, balls and O-rings. The second holds the wheels, rollers, bearings and hardware around them.

The same part can show up under both. The snap ring 80848009 has a hydraulic unit listing and a frame listing, and 80845015 and 80845011 are close cousins, one for each. When you search a number and get two results, choose by the ending that matches where the old part sat on the jack.

Bishamon Parts by Type

The largest type is rings, with 10 snap rings and 8 O-rings. After that come 12 listings that name a pin, 10 that name a roller, 9 a bearing and 8 a bushing. The rest is smaller: 5 springs or spring parts, 5 steer wheel assemblies, 5 nuts, 4 washers, 3 handle parts, and 2 each of seal kits, load wheels, bolts, hub caps and valve parts.

To compare with other brands, these pages cover the same types across the catalog: more than 950 pins, about 1,300 wheel bearings, about 360 bushings and more than 2,600 seals, gaskets and O-rings. The pins, springs, clips and rings page adds about 820 more. Rollers on the mast rollers page are written for forklifts, but it lists about 510 if you need to compare sizes.

Reading Bishamon Part Numbers

Bishamon numbers are eight digits, and in most listings the number comes first: "12003604 BEARING CUP FOR BISHAMON BS-55 HYDRAULIC UNIT." A few put it later, as in "Bishamon BS-55 Load Wheel Part # 12061323 - NEW" and "For Bishamon Ring - Snap 80848009." Searching the bare digits turns up either style.

Some numbers carry a suffix. The steer wheel assembly appears as 12061733-A1-HD, 12061733-A2-HD and 12061733-A1-ST, and there are two more, so the same eight digits sit behind five listings. The load roller assembly is 85007098-N-A. Treat the suffix as part of the number, because each version is its own listing.

Families of parts tend to share their opening digits. The O-rings (80800260, 80800023, 80800010) do, and so do the snap rings (80848009, 80846031, 80845011), the bearings (81036205, 81026304, 81046204) and the roll pins (90980835, 90980514). If you can read only the first few digits of a worn label, compare them with these groups to see which family the part belongs to.

Inside the Hydraulic Unit

This is where most of the 58 hydraulic unit listings live. The names are plain: balls (80843022), springs (52103653, 52103663), roll pins, bushings (81710121), a bearing cup (12003604), a control lever (12003943) and a handle pin (12003914). The sealing parts are the U-cup (52013563), the scraper (52103553), the O-rings and a seal kit (52103704).

When a jack stops holding a lift or sinks slowly, the seals and O-rings are the usual place to look first. Treat that as a starting point and not a diagnosis, because a worn spring or ball can cause similar symptoms. For parts that aren't listed under Bishamon, the hydraulic pumps, valves and cylinders page lists about 3,500 across all makes.

Frame, Wheels and Rollers

The frame group is about movement. It includes a load roller assembly (85007098-N-A), a load roller bracket (02103304), steer wheel assemblies, a traverse bearing (81251109), a hub cap (47MM), a spacer (25MM), a bolt (52008153), an adjusting nut (90931508) and a lifting link shaft (12007244). Sizes such as 47MM and 25MM are written into the listing, so read them against the old part.

For steering, there are five listings, and the steering page lists about 250 across brands. If your jack is not a Bishamon, the full pallet jack parts page lists more than 1,700 for other makes and models.

Seal Kits, New Tags and Repair Wording

A few listings carry a condition word in the name, so scan for it. Three say NEW, such as "Bishamon BS-55 Load Wheel Part # 12061323 - NEW" and "For Bishamon Pallet Jack Seal Kit - Part # 52103704 - New." Three are kits, and one uses repair wording. The rest give only the part name and the model, with no condition word at all.

The seal kit is worth a second look if you're rebuilding. It bundles the sealing parts in one number, but the individual O-rings, the U-cup and the scraper are also listed on their own. Compare the kit with the loose parts you'd need before you decide, and check the kit's name for the model.

Questions About Bishamon Listings

Are these genuine Bishamon parts?

Mostly no. They are aftermarket parts named for the Bishamon jack they suit. The word "NEW" appears in three listings, so check the name for it.

Can I buy a whole hydraulic unit?

The 58 hydraulic unit listings are named for parts used inside the unit, such as springs, balls, O-rings and bushings. Search the part name together with BS-55 to find the one you need.

Does a BS-65 jack use the same parts?

One listing names the BS-65, and the page doesn't say whether other parts overlap. Look for your model in the name before ordering.

Where do the parts ship from?

From our warehouse in Franklin Park, Illinois. The company has been in the parts business since 2005, and Bishamon is one of many pallet jack brands we list.
