Variable speed trigger switch
There were no instructions with the new parts.
Removing the old switch was difficult because the wires were wrapped through the pole eyes so they had to be heated then unfastened while still hot. I ended up heating them then just jerking them free with a pliers. The wires were not long enough to cut off the soldered ends so I had to carefully form them to fit through the pole eyes on the new switch before soldering them. I could have replaced the wires but then would have had to solder new wires onto the terminal posts of the motor and I wanted to avoid having to use a soldering gun on the motor for fear of damaging the motor. Although it was a fairly simple task it was complicated by the fact that I did not initially realize the wires were wrapped through the pole eyes before they were soldered at the factory.
Did these repair instructions help you?

Question: Working Less And Less

1041613

I've had the R8411503 for about4 years and its not wanting to work every time I pull the trigger. I'm assuming its the switch assembly but didn't know if it might be the motor. It used to be variable speed but not any more as well.

Hello 1041613,

The variable speed is controlled by the 270001400 switch. If it is not working all of the time I would assume that this is going to be your problem. Switches are one of the most common parts that fail on any power tool.

Question: Chuck Removal

I tried to follow the directions on the video, but the chuck housing just turns. Any other suggestions to get the front assembly apart?

Question: Ni-cad Or Lithium

anonymous

Is the R8411503 ni-cad or lithium? If it is lithium, can a ni-cad battery be used on it?

The battery for the R8411503 cordless hammer drill is part number 1320254011 is a Ni-Cd battery and you have to use a Ni-Cd charger for it.

Question: Motor Or Switch?

Joe

My 18v hammer drill had barely any use on it and one day it just stopped working. I didn't drop it or get it wet or anything like that. If you barely pull the trigger it will turn just a tiny bit then stop. I think it's the motor or the switch assembly. Any ideas?

Well I have the same symptoms. I desoldered the motor from the switch last night. The I hooked it straight to the battery. It started right up, so I guess it must be the switch.

Question: Ridgid Hammer Drill Help?

MB01

I have a Ridgid 1/2 hammer drill (model R8411503). I purchased this at Home Depot about 6 years ago as part of a set of tools. It came with a Lifetime Warranty but I unfortunately didn't register it or save the receipt. I have the documentation that came with the set but my understanding is that I needed to register the tool at time of purchase in order to use the warranty.

About 6 months ago I was using it to drill through some floor joist and it started to smoke. It still runs but only at low speed and there is a burning smell each time I use it. I really like this drill and would like to get it repaired if the cost is not above buying new set. Does anyone have a suggestion for repair?

Thanks for your help!

The transmission still appears to be strong. The drill is variable speed there was an electronic burning smell coming from the back end of the drill. Could I possibly have burnt out the motor?

burning smell is the lacquer coatings on the copper windings melting from overheating. replace the can motor.

this would not be covered under warranty as it is not a defect.

Thanks for your help!

Well Motor came on Friday and I was able to replace it in about an hour. Really not that hard at all. I am glad I went the new motor route instead of buying a new drill.
