Install Metal Center Drive Shaft on HP141/HP141S

Quick Answer

Installing a metal center drive shaft on your HP141 or HP141S is a straightforward swap that improves drivetrain durability. You will replace the stock plastic shaft with the metal part number 14403B using basic tools.

Installation Steps

1. Step 1: Remove the Stock Drive Shaft: Place the RC car on a clean work surface. Use a Phillips screwdriver to remove the two screws securing the center driveshaft cover (if present) on the chassis. Gently lift out the stock plastic shaft. Common mistake: Forgetting to note the orientation of the shaft – the metal replacement is symmetrical, but it's good practice to check alignment before removal.
2. Step 2: Prepare the Metal Shaft: Take the metal center drive shaft (14403B) and apply a small drop of thread-locker to each end where it contacts the differential output cups. This prevents the shaft from loosening during operation. Common mistake: Using too much thread-locker can cause it to seep into the bearings – a single drop is enough. Apply thread-locker sparingly to avoid contaminating bearings.
3. Step 3: Install the Metal Shaft: Slide the metal shaft into place, ensuring both ends seat fully into the front and rear differential cups. Replace the driveshaft cover (if equipped) and tighten the screws firmly but not over-tight. Common mistake: Not fully seating the shaft can cause drivetrain binding or noise – check that it spins freely by hand before securing the cover. After installation, rotate the wheels by hand to verify smooth drivetrain operation.
