This is an OEM authorized part. It is sold individually. This spring maintains pressure on the N078437 Sleeve, and the rest of the bit holder assembly, to keep the bit in the holder. If this part fails the bit cannot be held in the bit holder. It is commonly used in impact drivers, and is compatible with the impact drivers listed below.

perfect fit
Although it turned out this part was not broken on my impact driver, I replaced it anyway. My driver bits were falling out and I thought I would replace everything at this time. Works perfectly now.

Easy Repair - Impactor is like New!!
My parts arrived on time even during the Covid Virus Outbreak! I had to replace the spring but went ahead and ordered the ball, spring, and ball clip to make sure everything was new. So glad I didn’t have to buy another tool. The videos are a great helps as well.

The online video helped me isolate the issue... the prompt and efficient delivery of the replacement parts allowed me to fix the broken chuck on my DeWalt impact driver. A great company to work with.

1. I initially disassembled the chuck assembly. Unaware of the compressed spring under the compression ring and washer, the chuck slipped from my fingers and I lost the compression spring, washer and steel ball.
2. Upon receiving the parts, I reassembled the chuck , but it did not work properly.
3. I then disassembled the ch

4. I then reassembled the chuck placing the steel ball above the retention spring in the slot on the shaft rather than below the spring in the slot.
5. The chuck worked as designed after the second reassembly.
NOTE: I think that the video instruction you nicely provided should also include:
1. A warning that once the compression ring is released that the chuck and related parts are under pressure and should be held firmly so as not to lose any parts.
2. A note that indicates that the steel ball is to be placed above the ball retention spring rather than below the ball retention spring.
3. The second spring ( the ball retention spring ) should be named just that .
Thanks again for the ease of ordering parts on your website and the excellent video\'s that make repairs less daunting to the average DIY\'er
