Makita LXT202 BHP451 18 Volt Hammer Drill & BTD140 18 Volt Impact Driver Lithium Ion Combo Kit - Answered Questions & Fixed issues
Hammer drills Features
There are a few features you may want to pay attention to include: A Depth Rod mounted to the drill lets you know when the bit reaches the desired depth; Variable Speed Selection allows you to adjust the drill for specific jobs. Use high speed for small holes and low speed for large holes; Reverse can retrieve a hopelessly stuck bit; Removable Side Handles give the operator better control in normal use, and can be removed in confined spaces.
How to change brushes
on the BHP451 there are 2 screws on the back cover that need to be removed and then you can access the brushes and on the BTD 140 the same is true. The part number I see is 194427-5. If I have helped in answering your question would you please vote accordingly and thank you.
Broke bit inside chuck and
TAKE THE OUTER CHUCK PEICES OFF THE IMPACT!! THERE WILL BE A C-CLIP, WASHER, SPRING AND ONE OR TWO BALL BEARINGS AND THE OUTER HOUSING, IN THAT ORDER! WITH ALL OF THAT OFF, MOUNT THE ANVIL IN A BENCH VISE WITH BRASS JAWS OR BETWEEN TWO PEICES OF WOOD, UPSIDE DOWN!!!!!!!!!!!!!!! THE TRICK IS TO HAVE THE BIT FALL OUT OF THE CHUCK ONCE IT IS LOOSE!!!! NOW WITH IT MOUNTED IN THE VICE AND PRETTY TIGHT, TURN THE TOOL ON UNTILL IT FALLS OUT, IT WORKS GREAT IF HAVE DONE IT ABOUT 75 TIMES!! MOST PEOPLE THINK I'M A WIZARD!! BUT IT'S REALLY EASY. WITH IT MOUNTED SOLID IN THE VISE THE ANVIL HITS SO FAST AND HARD IT VIBRATES THE ANVIL, IF YOU DO NOT REMOVE THE BALL BEARINGS HOLDING THE BIT, YOU WILL BE DOING THIS ALL DAY. SOMETIMES, IN THE CHEAPER BITS IT WILL ROTATE AND GALL UP SO BAD THAT IT WILL NEVER COME OUT, IN THAT CASE YOUR BUYING A NEW ANVIL ASSY. JIMS TOOL SERVICE
My Makita BHP451 Li ion battery drill periodically
Bjarne, odds are the variable speed function of the trigger is failing. There are Makita repair centers that perform repair, and sell parts if you want to take it on as a DIY project. Before proceeding, I would make sure the warranty has expired. If it is still in warranty a Makita repair center should repair it for no charge.
My Makita BTD140 seems to be gradually losing
If the motor is working good then check the hammer and anvil to see if they are rounded over. A weak spring under the hammer can also add to this problem. Also check the spindle and the two steel balls that hold the hammer to the spindle. Sometimes the spindle will become chipped on the edge of the grooves and let the steel balls get out of alignment in relation to the hammer.
If the motor itself is loosing power with full batteries then you will need to check the brushes and the armature for damage. If the brushes are chipped or broken you should replace both the brushes and armature. Any questions please post back.
Electric Makita HP2051 chuck won't close
I don't really know how a chuck works. I use them often on a drill press, cordless drills, etc. My grandfather always said to "check the simple things first." Could something have gotten in the way like saw dust, dirt.....? ? I might suggest trying using compressed air and blow it out? You can buy a can of compressed air at office depot.
