Main Title: Understanding the Thread Size

Identifying the Correct Moving Block

In the United States, there are primarily two types of white moving blocks used in power recliners. The key difference lies in the thread size within the block, specifically where the worm screw passes through the center. To determine which moving block you need, examine the aluminum shaft for slots – one at the top and one at the bottom. Shine a light into the slot and observe the black worm screw.

Counting the Threads

To identify the thread size, use a tape measure or ruler to select a thread on the worm screw. Count the number of threads or turns until the next inch on the ruler. There are two possibilities: either 6 threads (part #6254) or 9 threads (part #6256) per inch. While the 9 thread per inch size is more common, it is crucial to ensure the correct measurement as there are still enough 6 thread blocks in use.

Importance of Checking Thread Size

Before placing an order for a moving block, it is essential to verify the thread size. Ordering the wrong size and attempting to install it on your motor can lead to complications. Unfortunately, we cannot accept returns for incorrectly ordered moving blocks. Therefore, it is crucial to double-check the thread size to ensure a seamless installation.
