The Ultimate Guide to Fixing a Leaking Happijac Hydraulic Jack

Fixing a leaking Happijac hydraulic jack is a common task for RV owners. While it can be a frustrating problem, it's often straightforward to fix with the right tools and knowledge.

Signs of a Leaking Happijac Hydraulic Jack

The most obvious sign of a leaking Happijac hydraulic jack is fluid leaking from the jack itself. This can happen from various places, including:
- The cylinder
- The fittings
- The hoses

Other signs of a leaking hydraulic jack include:

• The jack is slow to operate.

• The jack is making unusual noises.

What Causes a Happijac Hydraulic Jack to Leak?

There are several reasons why a Happijac hydraulic jack might leak. The most common causes include:

• Damaged seals: The seals are the rubber components that create a watertight seal between the different parts of the jack. If the seals are damaged, fluid can leak out.
• Loose fittings: The fittings that connect the hoses to the jack can become loose over time. This can also cause fluid leaks.
• Cracked hoses: The hoses that carry fluid to and from the jack can become cracked or damaged. This can lead to fluid leaks.
• Overfilling: If the jack is overfilled with fluid, it can put pressure on the seals and cause them to leak.

How to Fix a Leaking Happijac Hydraulic Jack

Fixing a leaking Happijac hydraulic jack is a multi-step process. The first step is to identify the source of the leak. Once you know where the leak is coming from, you can begin to fix it.

Tools and Materials You'll Need

Step-by-Step Instructions

1. Safety First: Before you begin, park your RV on a level surface and engage the parking brake. Chock the wheels to prevent the RV from moving.

2. Locate the Leak: Use a flashlight to inspect the jack for any signs of fluid leaking. Once you have located the leak, clean the area around it with a rag.

3. Raise the RV: Use a hydraulic jack and jack stands to raise the RV and take the weight off the leaking jack. Be sure to follow the manufacturer's instructions for using a hydraulic jack and jack stands.

4. Disconnect the Hoses: Use a socket wrench to disconnect the hydraulic hoses from the jack. Be careful not to lose any of the fluid that is in the hoses.

5. Remove the Jack: Use a socket wrench to remove the bolts that hold the jack in place. Once the bolts are removed, you can lift the jack off the RV.

6. Replace the Seals or Fittings: If the leak is coming from a damaged seal or fitting, you will need to replace it. To replace a seal, simply remove the old seal and install the new seal in its place. To replace a fitting, disconnect the fitting from the hose and install the new fitting in its place.

7. Reinstall the Jack: Once you have replaced the seals or fittings, you can reinstall the jack on the RV. Be sure to tighten the bolts securely.

8. Reconnect the Hoses: Reconnect the hydraulic hoses to the jack. Be sure to tighten the fittings securely.

9. Lower the RV: Use a hydraulic jack and jack stands to lower the RV. Be sure to follow the manufacturer's instructions for using a hydraulic jack and jack stands.

10. Check for Leaks: Once the RV is lowered, check for any signs of fluid leaks. If there are no leaks, you have successfully fixed the leak.
