Hi all,

The motor on my HF DC seems to be DOA – won’t turn on. In the mean time I purchased a replacement unit (easiest way to get the DC up and running on a Sunday afternoon) but I’d still like to replace/repair the shot motor and have a second DC. Any suggestions? The replacement motor from HF was ~$95. Having never had to deal with replacing/repairing a motor before I’m looking for advice on the most cost effective (aka “cheapest”) way to get the 2d DC up and running.

“Won’t turn on” could be any number of things! I’d pull out the meter and start troubleshooting before I go out buying a new motor. See if you have power on both sides of the switch when you turn it to the “on” position so you can rule it out. Check that you have voltage at the motor to rule out wiring, etc.. I don’t know if that unit has any circuit protection, but if it does, check on both sides to make sure it’s working. If it really is the motor, those can be fixed as well depending on what is wrong.. which means you gotta yank it apart and find out first. Might be something as simple as a worn/broken brush or spring.


PS: What kind of motor does it have?

You’re going to need a bearing puller to start taking her apart. Check the automotive stores; they’re $10 or less. I think that motor’s worth $100 but you might consider going with a different one. I’ve seen new Baldors on CL for a tad more. This is one of HF’s only good offerings; I hope you end up happy.

Check the switch. Mine went south, I took it apart and cleaned the contacts after I ordered a new one. Works like a champ, and I now have a spare switch.
$4.50 for the switch and $5.00 shipping-Duh!
As my old mentor said, “When in doubt, check the obvious”. He was a smart dude.

Yea, I second the “check the switch”. Mine melted, I replaced it with a higher amp toggle switch that I got at Home Depot for $3.

You mentioned a second dc. For 50 bucks more you can get the whole dc.(149.00)

Use your air compressor to blow out any openings where dust might have accumulated.

Yeh, my HF DC switch is going out. That was the first thing I thought of when I read the OP’s post.

Thanks all for the feedback. The unit is 4+ years old. I’ll check the switch with the multimeter tonight. Kickin’ myself for not thinking of that.

Bearing puller- check with a local auto parts store. Many of them “rent” tools- you put a deposit on the tool, use it and return it and get your deposit back. Our Autozone store does this.
