Questions & Answers

Hello My device is slipping. The drill stops but the engine continues to run at full speed. Especially when I put a mixer on the device, it slips through. (I do not mean the adjustable positions) Does anyone know how I can solve this?
philip for model number makita dhp482
Hello Philip, thank you for inquiring. This may be due to a faulty Gear Assembly, part number 123443-0 for your model. Good luck with your repair!

Question: Drill Does Not Turn Smoothly

1174371

My Makita was working great then I stupidly left it outside for a week. Now when running at low speed it does not turn smoothly, it turns a 1/8 of a turn pauses then turns 1/8 a turn repeatedly. When running at high speeds the effect is not as noticeable but operation does not seems smooth. The brushes are not very worn but they have a small indent where the retaining spring holds them in place. Anyone encounter this before?
WJA
Hello 1174371,

You may have got some moisture between the 638425-4 yoke unit and the 619198-8 armature. There may be some rust build up between them. I would think this would affect the motor in slower speeds rather in high speeds.

Question: Makita BHP452 Quit Spinning

dwol

My Makita BHP452 quit spinning, but only at the chuck. The drill motor still spins and works properly in forward and revers, but somehow is not engaging the chuck part. I have tried forward and reverse, but it just seems to spin internally and the chuck just floats with no power. (almost like a broken shaft of some sort) what do you think is wrong? and what part to replace?
Hi dWol,In most cases that indicates the pinion gear on the motor has loosened up. A bad transmission can generally be check by running the drill and shifting it from high to low gear .If the transmision is bad it will make a clattering or grinding sound.Hope this helps.Good luck.

how to repair pinion gear on motor
WJA
Hello 1739788,

To replace the pinion gear on the Makita BHP452 18V LXT Lithium-Ion Cordless 1/2" Hammer Drill-Driver. You would have to replace the complete Armature. The pinion gear is not provided as a part separately.

Question: Switch?

MSlap03

My Makita BHP452 18V drill has worked great for me. Just recently though I noticed I don't really have any othe speed than high speed and I have to compress the trigger all the way. I blew it all out still does it. I still make use of it just would be nice to have the variable speed too. My question is is this just a faulty switch or is it more?
Hi MSlap03,
Yes your switch is bad.The high side of the circuit is burned out.You need a Switch Part Number: 650583-6. Hope that helps.Good Luck.

Question: Chuck Screw (M6x26)

Gridman

hi gridman,As a rule of thumb drills that have a forward and reverse will have a left hand thread chuck retaining screw and the chuck will be right handed. Hope that helps.
