Question: Dimensions Of Motor
What is the overall size and width of motor? What is the shaft diameter?
Can the timing sprocket be removed?
If we had a 396505-20SV motor and pinion in stock, I would be glad to give you the information you are looking for. You might try contacting a Dewalt Factory Service Center in your area to see if they have one in stock and can give you the dimensions.
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.
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???
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.
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.
