Powerboss Parts

Squeegees lead the 415 listings in this Powerboss parts collection, with about 50, followed by filters at about 40, then hoses, brushes, brooms and motors at 18 to 20 listings each. The rest is what a floor scrubber keeps asking for: switches, gaskets, bearings and plenty of hardware. Most listings are aftermarket replacements made to fit Powerboss machines, so check the number in the listing against the one stamped or printed on the worn part.

A few hundred listings is small enough to scan by group. The sections below walk through each group, show how Powerboss numbers look in the listings, and point to the wider collections when the part you need is generic hardware.

Powerboss Parts by Type

The squeegee group is the biggest, at about 50 listings. They're worded plainly, as in "3308816 SQUEEGEE" or "3054793 SQUEEGEE," and a related listing covers the pick-up hose that carries water away from the squeegee ("3300335 HOSE-SQUEEGEE PICK-UP 2-1/2"). If you need squeegees for other scrubbers as well, the floor scrubber squeegees page holds about 520 of them.

Hoses are a mid-sized group here, with 19 listings, including vacuum drain and dump hoses, plus 5 hose cuffs. Brushes and brooms are similar in size, at 18 brushes and 20 broom listings. Both groups sit inside a larger scrubber squeegees, brushes and pads collection of about 1,150 parts, and the scrub brushes page alone has about 470.

On the electrical side, there are 20 motor listings, 10 of them vacuum motors, with 13 switches alongside them and 2 ignition coils. Browse wider selections on the electric motors and brushes page, which has about 555 parts, or on the switches page, with about 1,500.

Squeegees, Brushes and Brooms

These parts touch the floor, so the wording and size in each listing do most of the identifying. One side broom reads "361207, Side Brook, 6 Poly." The word "Brook" is a typo for broom, so search by the number rather than the word. A brush listing reads "731090 Nylon Brush Broom For Powerboss Standard Fill Patern 45," which gives a 45 inch length, and another size shows up as 36 IN.

Brushes and brooms name poly, nylon or wire, and squeegees name urethane, neoprene or gum. Read the size first and measure your old brush or broom against it. If the squeegee is what's failing, note that a skirt and a rear tension band are separate listings ("96125844, Rear Tension Band" is one).

Engine, Electrical and Drive Parts

Not every Powerboss machine is battery-only, and the listings show it. There are engine parts such as an ignition coil ("3340233 COIL IGNITION"), a fuel filter ("3303324 FILTER - FUEL"), an air filter ("3302597 FILTER - AIR"), an oil filter ("3340147") and a radiator ("3301995 RADIATOR"). Filters of every kind add up to about 40 listings, second only to the squeegees.

For battery machines, 7 listings mention 36 volts, including a charger ("957727, Charger, 36V"). Beyond those, there are 5 breakers, a solenoid ("730899, Solenoid"), 5 pumps and 4 brake listings. A short note on wear: squeegee blades, brushes, brooms, hoses and filters are the parts that wear out through normal use, so those groups are the usual starting point when something stops working as it did.

Reading Powerboss Part Numbers

Powerboss numbers are mostly plain digits with no dashes. Many are seven digits starting with 33, such as 3302597 and 3313136, while others are shorter (361207, 450090) or longer (01179200, 96125844). A few end in a letter, like "304387K SWITCH." Keep any leading zero when you type the number, because "01179200" and "1179200" aren't the same search.

The position of the number changes from listing to listing. Most put it right after the brand, but some put it at the end, as in "HOSE - DUMP 200289," so a search on the digits alone is more reliable than a search on the whole phrase. Only nine listings have a dashed number, for example the hex nut "05-332."

Powerboss is also spelled two ways. About 22 listings read "Power Boss" with a space, such as "FOR POWER BOSS Oil Filter 3340147," and the rest read "Powerboss." If a search for one spelling turns up nothing, try the other. Altogether, 367 of the 415 listings begin with "For," which is how a part made to fit a machine is labeled, not a part made by Powerboss.

Hardware, Gaskets and Bearings

A scrubber rebuild uses a lot of small parts, and the Powerboss range covers them: 19 nuts, 12 bolts and 11 washers, along with 13 gaskets, 11 bearings, 8 springs, 7 belts, 7 casters and 4 clamps.

Each listing names the kind of fastener. Examples are "711373, Lock Nut," "712668, Wing Nut" and "11039567 BOLT - HEX- M8", which also gives the thread size.

When the thing you need is a common fastener, the larger pages can have more choice: nuts (more than 3,200), bolts, screws and studs (more than 4,500), seals, gaskets and O-rings (more than 2,600) and wheel bearings (about 1,300). Use the Powerboss listing when you want the exact reference number, and the wider page when only the size matters.

Repair Kits and Spray Paint

Six listings are kits, which bundle several small parts so you don't have to buy each one on its own. There's also spray paint, such as "3331464, Spray Paint, Light Gray," with 3 paint listings in all. Latches (8) and plugs (4) round out the smaller items.

For anything the Powerboss collection doesn't cover, the main floor scrubber parts page lists more than 4,600 parts across makes.

Powerboss Parts FAQ

Are these made by Powerboss?

No. Most of the catalog is aftermarket, and a listing that starts with "For Powerboss" is a part made to match that equipment. The brand name and part number are there for reference.

Should I search Powerboss or Power Boss?

Try both. The listings use the one-word and two-word spellings, so a search on only one can miss part of the range. The digits of the part number work with either.

How long has MRK Sales been selling parts?

Since 2005, from a warehouse in Franklin Park, Illinois. If you've bought from the ouroverstock account on eBay, that was us, selling there since 2004. It's a Top Rated Seller there, with 99.9% positive feedback and over 200,000 items sold.

What if my part number isn't in the list?

Search the digits alone, with and without leading zeros, then browse the part-type group. If the part is generic hardware, the wider nuts, bolts and washers pages carry far more sizes.
