Most worn parts on a forklift

Forklift Parts You Need To Keep An Eye On

Forklifts require regular maintenance and daily checks. You should make sure the most important forklift parts are checked and double-checked! Some parts contribute more than others when it comes to safe use. Keep the parts listed below always properly maintained.

Unexpected downtime due to breakdowns can have a negative impact on operations. We recommend to have common forklift parts on hand for maintenance and repairs.
TiresIf your forklift tires are bald, cracked or worn you need to replace them - before an accident happens! Without the correct tires, with sufficient tread, the driver risks losing control of the forklift, especially on smooth floors.

Warning Indicators

The lights, signals, horn and more are taken to be a single part which works for accident prevention. Included in the warning indicators is the display showing pressure and temperature of the transmission and engine. Fixing any faults with warning indicators can prevent further costs down the line. Regular checks and maintenance are proven to be the best method to stay ahead of problems.

Brakes

A forklift's brakes could be considered the most important part to regularly check and maintain. They are constantly working to decelerate and stop your forklift after every movement, often while the unit is carrying large amounts of cargo. Whether your unit has brake pads, drum brakes or other braking system such as oil-cooled, your brakes will need to be replaced regularly. It is imperative to check and replace worn-out brakes at the first sign of wear to ensure the forklift can be stopped safely and in a timely manner. Failure to maintain brakes properly will more than likely result in injury, even fatality, and product or capital equipment damage.

Mast Chains

Mast chains are used to extend a forklift's mast and carriage. With every movement they are put under incredible strain. As they're responsible for the lifting of heavy loads and managing the weight at extended heights, mast chains need to be checked on a regular basis and replaced at the first sign of wear or damage. Failure to properly maintain and replace damaged mast chains can lead to severe injuries, fatalities, and product damage.

Filters

Regularly replacing filters as per manufacturer's routine maintenance guidelines is imperative to prolonging the operating life of a forklift. Dirty or clogged filters can be a sign of an operating area with poor air quality or cleanliness that needs improving for better health and safety.

Generic Parts Specializes in Replacement Parts for Electric Lift Trucks, Electric Walkie Jacks, and Manual Pallet Jacks.

Generally, Electric Walkies get a lot of use and abuse. Our GW Wheels and Wheel Kits, Chargers, and large inventories of hard parts make us a great source for high quality and lower costs. 

Wheels need to be replaced. Check out our selection of Wheel kits and Tires:

Electric Walkies normally have four 6 volt batteries onboard (24 volts) as well as their own battery charger. We see fair demand for our chargers. In terms of how the Walkies are used to load and unload trailers or move pallets in stores, delivery trucks with lift gates often carry their own walkie jacks plugged in overnight to recharge.

Steer Wheels - which ones are best for your pallet jack?

There is a host of different materials for steer wheels available. 

Polyurethane and Ultra-Polyurethane treads are the most common wheel treads you'll encounter on a pallet jack.

What's best for your pallet jack depends on where and how you use it.

 

Poly Tread on Nylon Hub

These have a chemical bond that secures the poly tread to a steel core (or hub). This option is ideal for display floors, carpeting, and warehouses. They mark floors the least while rolling easily and quietly. Under really heavy loads (2,500lb +), if left to sit for more than 8 hours, there is a possibility of the wheels flat-spotting.

Ultra-Poly Tread on Aluminum hub

Longer lasting and they roll more easily than regular poly, also a chemical bond on a steel core. Ultra-poly is very hard and won't shatter like nylon if too cold (i.e. in and out of a freezer). They are also non-marking with the possibility of flat-spotting, as mentioned above.

Solid Nylon Wheel 

This is a harder material that is best for cold storage applications. It is also the material of choice for use in environments that may cause rust or corrosion like poultry processing, and working with seafood. It can also be the best choice for refrigerated transport trucks that have grated floors. Lastly, they can be a good choice if the pallet truck is taken outside on the rough pavement. However these are more likely than poly to mark floors, so be mindful when using inside a showroom or a hotel lobby, for example.

Solid Steel Wheel 

When all else fails you may need solid steel wheels. These are best for use on factory floors where there may be metal shavings or hard debris on the floor, and where noise is not an issue. What they lack in their ability for use in a sneak attack (they’re pretty loud) they make up for in sheer durability. These are also a good choice if you need to work outside on rough asphalt. But they can damage nice floors, so avoid use on floors you want to remain "pretty".

One Wheel or Two?

Now that you've got an idea of which type of wheel is best for your specific uses you are faced with another sometimes tough decision. One wheel or two?
First, most pallet jacks have two steer wheels. They are located on the main body of the jack, attached to the hydraulic unit, and therefore the handle. 

Unless a pallet jack is brand new, we always recommend replacing both steer wheels at the same time. There is a legitimate benefit:   
Steer wheels wear down and get shorter the longer you have used them. Steer wheels (like pallet jack load wheels, or the tires on your car) do not act independently but are a portion of a larger machine. Even a small difference in diameter causes stress on the mating (aka connected) parts which then causes issues down the line. 

You find all variation wheels for most pallet jack brands here.

Because we so strongly advocate changing both at the same time we created wheel kits to get you everything you need, even the load wheels, and they are priced so that the hardware comes for free. 

Here is an example:

General Maintenance on Your Pallet Jack

Keeping your pallet jack in good working condition limits its downtime, and saves you money in the long run.

Here are some helpful hints when repairing and performing maintenance on your pallet jacks

• Never hammer directly on an axle; always use a pin punch.
• Always replace old roll pins.  It is very important to use the correct roll pin to prevent damage to the mating (=connecting) parts.
• Replace accessible bushings whenever the jack is disassembled. Our custom-designed bushing extractor makes it quick and easy to remove all bushings.

Load Rollers

Load rollers should have neither flat spots nor large pieces of metal embedded in them (i.e. tacks, nails, or metal shavings). Any chips in the wheel that keep it from rolling smoothly indicate the need for replacement. If the wheel has cracks, loose tread, or does not turn freely, replace both wheels. Always change the wheels in pairs to reduce uneven wear. 

New load rollers have an outside diameter of 3" (PTH50) or 3 1/4" (PTH). If the diameter is worn more than 1/4" from normal size, replacement is necessary.

For step-by-step instructions on how to replace the load wheels, watch our video.

Steer Wheels

Steer wheels should have neither flat spots nor large pieces of metal embedded in them (i.e. tacks, nails, or metal shavings). Chips in the wheel which keep it from rolling smoothly indicate replacement. Steer wheels should turn freely. They should not rub the bottom of the traverse. 

If the diameter is worn more than 1/4" from the normal size, replacement is necessary.

Handle

Inspect the handle for cracks and structural integrity. There should be minimal side play in the handle bracket. Check for worn bushings.
If bushings are not replaced regularly, the handle bracket holes can become worn. Damaged holes cause pin failure and may require complete replacement. Also, inspect the handle pin and roller for flat areas and wear. If any of the above parts are worn more than 1/16", replace them.

Hydraulic Unit Service Hints

• Tampering and abuse are two of the most common problems. In most cases, minor repairs become major when inexperienced people attempt to rebuild a hydraulic unit. If you come across a unit that looks like it has been tampered with or modified, inspect the unit carefully to be sure it can be rebuilt or call Generic Parts Service for technical assistance (1-800-331-0839).
• The pump piston and ram are polished to a fine finish for maximum seal life and minimum oil leakage. If you see these surfaces nicked or pitted, this will cause the unit to fail in a short time. Replace any rusty or damaged parts that will cause premature wear on their mating parts or the body of the hydraulic unit.
• Use UNI-HO hydraulic oil. Do not use automotive oil or hydraulic brake fluid.
