What to do if your pallet jack is not lifting anymore?

 Your Crown PTH50 pallet jack (or a jack with a similar pump) is not lifting anymore.

Your first step is to bleed the pump: 

Put the lever in the release position and pump the handle. About 10 times. That will cycle any air bubbles out of the valve.

If there is still no lifting, check the oil level in the pump. Unscrew the fill plug and check. You should see oil in there, but only to about an inch below the top—not all the way full!

Disconnect the lifting link from the lever and pump the handle: if the pump is lifting, your problem is with the lifting link in the handle. If it is not lifting, your problem is in the pump.

Now you isolated the problem, you can check with us to see if we have a replacement pump or you may decide to rebuild your hydraulic unit with one of our seal kits. 

We have how-to videos to help you.

We break the process down into 3 parts:
1) Remove from pallet jack
2) Take the unit apart and drain
3) Rebuild with new seal kit

Why ID your pallet jack?

Why bother to Identify Your Jack?

One of the most common calls we receive in customer service goes like this...

Me - Thank you for calling Generic Parts, this is Nicole how can I help you?

You - Hey, I've got this pallet jack, don't know the brand but I need the load wheels. Can you help me with that? Is there a generic (no pun intended) wheel I can use?

Me - We carry wheels for most jacks out there. Can you send me a picture of the hydraulic unit? I can use that to identify what you have and then I'll know what wheels you need. You can e-mail or text a pic to our Customer Service. Can I give you that info?

Now at this point the conversation can go one of many ways. Some simply ask where they can send the picture. Some become very confused as to why a pic of the pump will get the wheels. Then some just decide it's too much work and they don't want to mess with it. 

If you fall into the 2nd or 3rd category there's no need to be confused, frustrated or feel the task is too great my wheel replacing friends!

With so many different types and styles of manual pallet jacks, you may be thinking it's a hassle when you can just buy a new one (we have those too by the way - and they have a 3 year warranty).

I have a secret to tell you -based on a photo of your pallet jack pump, we can quickly and accurately determine the make/model of your pallet jack 99% of the time. It is really that easy.

Why spend $300+ on a pallet jack (and have to figure out what to do with the "dead" one you are replacing) when the remedy can be much less expensive and we do most of the heavy lifting (pun completely intended)

Here's how the process works:

1. Text a side view of the hydraulic pump to (503)523-8990 (include your contact info)- Or - E-mail a side-view photo of the hydraulic pump to CSinfo@GenericParts.com

2. In-house technician ID's unit based on photo submission

3. We call you up with a quote (or send written quote via e-mail)

4. You order replacement parts online or call (800)331-0839



What is a "side-view photo" you ask? Here is an example. It's the most helpful view for us to see the pump body and some of the features that may determine a specific factory variation.

That's it! Once we know what you have we have tools like exploded view breakdowns and videos to guide you through an efficient repair process.

Running low on time or unable to send the photo...? I'm going to share with you a resource we created so you can identify the jack. It's called the hydraulic unit identification sheet so you can identify what you have also.

Pretty neat what a single, clear and correctly positioned photo can accomplish.

Your customer will be happy with right parts the first time. Your bottom line grows with new resources to increase business and support to customer relationships. The landfill is one pallet jack lighter.

We hope you found this blog post helpful! Have an idea or topic for us to cover in the future? Send them over to CSInfo@Genericparts.com !

Pallet Jack Hydraulic Unit Inspection Tips

Inspect the outside of the pallet jack hydraulic pump for oil leaks. Test the hydraulic unit under a load to determine if there is a problem. 

This can be done by lifting a heavy pallet and letting it stand for 15-20 minutes.

Trouble shooting tips for possible problems with your hydraulic unit:

Jack fails to lift load:

1. Air lock inside pump - place the control lever into release position, then pump the handle rapidly about 10-15 times.
2. Low fluid level - with the jack lowered, remove filler plug. Fill the reservoir until the oil is level with the fill plug hole. Bleed the unit. Replace the filler plug, creating a snug fit. Do not over-tighten.

Jack fails to lower:

1. Look for any bent frame parts (lifting link, push rod, etc.) Bent frame parts need to be replaced.
2. The handle control may be out of adjustment.

Jack lifts in short increments:

1. Lack of oil pressure - check fluid level.
2. Reservoir filler plug leaking - replace the washer and filler plug and replenish oil as necessary.

One fork lifts, the other does not:

Check for damage in the following areas and their attached parts:

1. Lifting link (lifting link pin and traverse shoulder pin)
2. Pushrod
3. Load roller bracket (pivot axle)

Note: 
Always use SP UNI-HO hydraulic oil. Do not use automotive oil or hydraulic brake fluid.

Seal kits for repairing your hydraulic unit

Looking to rebuild the hydraulic unit on your manual pallet jack?

Below are outlined the differences between a super seal kit, standard and slim seal kit. 

Super seal kits contain all parts that are included in a standard seal kit, as well as the most commonly needed parts beyond the standard seal kit to do a complete hydraulic unit rebuild.

Standard seal kits have all of the parts included in the manufacturers' standard seal kit.

Slim seal kits include only the most essential and commonly replaced seals. A cost saving option if you know what you need. A Standard or Super seal kit is a better choice if a complete hydraulic unit rebuild is necessary.

Rebuild hydraulic unit program also available. Email or call us today (800)331-0839!
