Question: Dewalt Drill Transmission Rebuil...

Drew987

I took apart a Dewalt DW987 18V Drill to replace the outer shell.
As it came apart, the transmission fell out and some gears fell out.
I'm looking for diagrams or videos showing how to put the transmission back together.
Specifically, I'm not sure how the pin that connects to the torque setting connects to the wavy metal ring.
Hi Drew987,
I'm sorry but I don't know of any pictures or video that shows how to put the transmission back together.I've had a number of these transmission come into our shop and its always a trick to try to get them back together as they have made so many different types and changes on existing models .You might try utube.I wish I could give you better help.Good luck.

Question: DW987 Transmission Or Gearbox?

Waferboy

I'm having trouble determining which part is bad in my DW987. The clutch does seem to grab fine ~if~ the chuck turns. The motor turns but the chuck doesn't. It will seem to work fairly well if I point the drill down or tap the chuck face on the countertop. But after a bit it will stop spinning again.

I'm leaning towards the transmission. Any help/thoughts would be great!

Thanks!
Hi Waferboy, The part you need is Transmission Part Number: 397892-05SV.But check you date code as this might be warranty as Dewalt had a lot of problems with this transmission unit.Hope that helps.

Question: How To Reassemble The Transmissi...

JTS

I recently had to take my Dewalt DW980 cordless drill apart to clean, and when I went to put it back together I ended up with several extra parts which I can't figure out where they go. When the transmission was taken out all the gears and whatnot came out, and once I put it back together there were still these 5 little metal pins left as well as a little metal piece with one pin on each side and a metal piece in the center. I've looked all over, but just don't see anywhere where these pieces could possibly go or what they're even called to look them up.

Thanks
WJA
Hello JTS,

If you could post an image of the extra parts you have left over, it might be easier to identify them and then let you know where they go.

Here's an image of the pieces.

For some reason the image didn't post properly the first time, but I've fixed it. So does anyone know where these parts could go???

Hello JTS,

Well I thought that once we saw the parts that you are having a issue with, it would be an easy fix. But talking to a tech, the last time he had a transmission fall apart on him (2 years ago). He had to get another one and carefully take it apart to see how it all went back together. At this point his memory fails him on the parts in question. Hopefully someone out there will see this and be able to help you out. We'll keep trying though.

-WJA
Hi JTS, The large bottom pin is the detent pin that goes behind the detent spring.This keeps pressure on the torque adjustment collar. the other parts are cam followers that are position on the front of the transmission .When you pulled the transmission fron the gear case housing the shaft from the gear case housing that went into the transmission went into a small collar.Those rollers go round that collar.Its hard to explain without a exploded view of the transmission.Hope that helps a little.
