No, unfortunately this is brushes only come as part of the motor assembly Makita 6226DWE 3 8 Cordless Driver Drill Parts

Try pulling out the brushes and blow some air in were the brushes go it may have gotten some trash in between the brush and the armature . they may need to be replaced, here is a pleace that will give you a breakdown and sell you the parts. http://www.ereplacementparts.com/makita-hr3851-rotary-hammer-parts-c-97_380_491.html

You can try the website makitauk.com select parts then choose your tool. Unfortunately it does not break the gearbox down to any detail as it can only be obtained as a complete unit.

I am a Makita dealer and service center and I cannot find a Makita tool with the model number BHP453. They do make a BHP452 and BHP454. If you go to the Makita website at www.makitatools.com and put BHP45 in the search box you can get the manuals and breakdowns for those tools and see if they match what you have.

I answered that question already on another post, but if you need to know how to remove the chuck I have detailed instructions in the TIP SECTION on how to do this. Let me know if you need more help

the switch or motor is wired incorrectly. These parts are polarity sensitive. The smoking I would assume is from the old switch and now the rotation is reversed. Let me know if you need more assistance.

JUST NEEDS A NEW SWITCH, EASY TO CHANGE WITH A LITTLE PATIENCE. YOUR LOCAL SERVICE CENTER CAN SELL YOU ONE OR WALK YOU THROUGH IT!! THE OTHER THING IT COULD BE IS THAT THERE IS A CHUNK OF DEBRIS IN THE TOOL OR THE HOUSING IS JACKED UP WERE IT HOLDS THE SWITCH INTO PLACE! I HAVE SEEN ALL SORTS OF THINGS HOLDING UP SWITCHES IN CORDLESS TOOLS!!!!! WORSE CASE IT WILL COST YOU AROUND $50 FOR A NEW SWITCH POSSIBLY ALLOT LESS. THANKS JIMS TOOL SERVICE
