How to Convert Your Simple Pump LBLD Motor to Hand Pump Mode – Quick Step-by-Step Guide

If you rely on a Simple Pump with an LBLD motor and need to switch to hand pump mode—whether due to a battery issue or preference for manual operation—this guide walks you through the process step-by-step. Converting to hand pump mode is straightforward and requires no special safety equipment beyond basic precautions.

‍

‍

Tools & Materials Needed

‍

• Two crescent wrenches
• 5/16" Allen wrench (for clevis on the LBLD)
• 3/16" Allen wrench (to remove quarter 20 bolts)
• Ratchet (optional, for bolt removal)
• 9/64" Allen wrench (for cover bolts)
• Hand pump handle assembly

‍

Tip: Always disconnect the power source before starting to ensure safety.

‍

Step 1: Power Down and Remove the Cover

‍

1. Disconnect Power: Even if the dry switch is off, unplug or disconnect power to the motor.
2. Remove Cover Bolts: Use the 9/64" Allen wrench to remove the six bolts securing the cover.
3. Set Cover Aside: Place the cover safely aside to access internal components.

‍

Step 2: Loosen Clevis Bolts

‍

1. Use the 5/16" Allen wrench to loosen the clevis bolts connecting the LBLD motor drive to the pump rod.
2. Once loose, the clevis will spin freely, allowing easier removal.

‍

Step 3: Remove Drive System Bolts

‍

1. With your ratchet and 3/16" Allen wrench, remove the four quarter 20 bolts holding the drive system to the pump head.
2. Loosen these bolts partially before fully removing them to reduce binding.

‍

Step 4: Detach Drive System

‍

1. Carefully lift the drive system off the pump head assembly.
2. If it binds on the clevis, gently jiggle it until free.
3. Set the drive system aside.

‍

Step 5: Remove Pump Rod Extension

‍

1. Locate the pump rod extension; it uses left-hand threads.
2. Use crescent wrenches to loosen and remove the rod extension (turn clockwise to loosen).

‍

Step 6: Assemble the Hand Pump Handle

‍

1. Confirm the handle assembly is complete: bracket connected to the link arm, the link arm to lever arm, and clevis to the end of the lever arm.
2. Attach the clevis to the pump rod using left-hand threads (tighten by turning counterclockwise).
3. Use your crescent wrench and the handle itself as leverage to secure tightly.

‍

Step 7: Attach the Handle to the Pump Head

‍

1. Use the shorter quarter 20 half-inch bolts (not the longer 3/4 inch ones removed earlier).
2. The holes may not line up initially because the piston is resting on the bottom of the cylinder.
3. Lift the pump rod slightly to line up the holes. This can be tricky alone.

‍

Tip: A new PVC clip tool (in development) will soon be available to hold the rod up for easier installation.

‍

1. Insert and thread all four bolts to secure the handle assembly.
2. Tighten all bolts firmly with your Allen wrench.

‍

Step 8: Test Your Hand Pump Mode

‍

1. Your handle is now securely installed.
2. Operate the pump handle manually as you normally would.
3. Check for smooth movement and proper water flow.

‍

Safety Tips & Best Practices

‍

• Always disconnect power before working on your pump.
• Work in a clean, well-lit area.
• Keep tools organized to prevent delays or lost parts.
• Regularly inspect and maintain your pump to ensure longevity.
