My 18v lxt wont work ln low gear

I KNOW IT !!! MAKITA the first gear is damaged the notches in the gearbox (planet-transmission)are grinded away about 2 or 3 mm are left and the gear shaft will not fit in the notches anymore , MAKITA the BDF 4** and many more models have all the same gear box problem, (NOT EVERY MODEL of MAKITA but much models ) LXT 18V and ??? because of the planet transmission GEAR BOX they are oft very vulnerable to switch over from one to 2 or from 2 to gear 1 the gearbox should anyway be replaced , and switch the topswitch on top of the machine without use the power switch at the same time its must standstill allways when shifting 1 to 2 or vice versa, inside the top switch there are special 2 springs build in inside to switch without turning because its have nothing to do with a synchronic gear box of a car , or choice to prevalence of repetition if you will not have again this trouble again buy Panasonic or Festool powertools this if you have people who are working with your tools you should never have problems with gearboxes anymore because of that notorious MAKITA problem by much models of Makita BDF4** and may be more models is also proven that have i so much this problem seen and repaired . but the gearbox itself from MAKITA is also not so expensive in compare to other powertools. but other tools moastly are selling individual parts like gearshafts and have metal notches instead of cheap plastic and not separate to buy, Makita delivered only 1 complete gearbox because its cheaper to get and all of the parts are new . marketing technical choice of MAKITA.

As long as the shifter is fully engaging then you will need to replace the transmission. It comes as one complete assembly. Here is a diagram with part numbers. The trans is part #125433-9 (reference number 12) and is just over $53

Replacement battery info for old 6041D 4.8vcordless 3/8" Makita Drill- I need price of battery & instructions for installation

the battery lists for 36.85 and you can find a breakdown and also point of purchase at, BUT note that most of the parts for this tool are obsolete no replacement when thinking about replacing this. It might be wiser and cheaper to buy a replacement tool at this point. Let me know if you need more assistance.

Drill will not turn but will you can here a grinding sound. Drill will turn when done by hand. Drill has not been run for over three years.

The gears are worn out,take it apart to verify. They need to be washed out with mineral spirits and greased if okey,otherwise they wear out the gears

Buy a new one on--- Tool

Struggling to remove chuck from makita 84444d

K what you need to do is remove the chuck retaining screw LH threads and then switch the gear selector to low and the clutch to drill only. Find a bent handle allen wrench about the chuck capacity and lock it in the jaws. put the chuck on a workbench or block of wood and on the long part of the wrench have it at about a 30 degree angle and strike it counter clockwise and that should remove it. you might have to hit it a couple times

Clutch slipping on cordless drill. need spare parts to repair.

Are you sure you do not have a tourque adjustment problem. If not I do not believe Makita will want to send you parts,you would have to know what is precisely wrong and by the time you went back and forth you might as well find nearest dealer for repairs and google search for service parts near you + zip code to get your drill fixed.

Thanks , Please rate jj505

I need to find a manual for the makita 18v lxt angle grinder. my problem being that when i put the battery on the lights flash up red and during use the lights do not work at all. please help.

Hi, Don't stress, its working fine. The grinder has a sort of self test when you put the battery in, it blinks. What you don't want is the light to come on when you are using it. That means that you are bogging it down and if on for 30 seconds ( if I remember right) it will shut the grinder off until you reset it by turning it off and then on again. So no worries!
