Makita Hammer Drill Repair - How to Replace the Gear Assembly

[@beachbum92629ca]

You just saved me $50-$60. My problem was not the clutch slipping, it was the speed-selector in the middle. KZbin saved the day once again with great how-to videos.

Thank you for the note about the gear selector being between settings producing symptoms similar to a bad gear set. It saved me some heart ache, time, and money at a crucial time.

It was the selector switch in a goofy spot. Saved me grief. Many thanks

Excellent video Short, detailed and to the point

Excellent video, thanks for posting.

If the chuck won’t break loose then you can disassemble the gears on the old gearbox after it’s out of the handle and I believe it was a 9/32 socket that fit on the input shaft. Long handle ratchet on the input and the Allen wrench in the chuck seemed to work pretty well to break them apart

[@Rich606]

The chuck WILL NOT just come apart with a tap of the hammer if your drill has seen any use. Luckily you're already replacing the gearbox so it doesn't matter if you smash it to pieces to get to the end of the shaft with some grips, like I had to. Other than that, top video. Very helpful 👍

Do you know anyone in Southern CA who do tune ups or repairs on Makita drills? I have 3 that need to be tuned up some gears seem to be stripped on one when doing heavy drilling. thank you

[@danpatterson8009]

If the speed-selector switch is in the middle between "high" and "low", the motor won't couple to the chuck and it will feel like the gear assembly is shot. Check this before ordering parts!

Hi I’ve got a Mikita dhp482 please can you advise me I’ve changed the bushes also a new motor but my drill still whan’t work at all battery is fully charged the light on drill works but not the drill it self SOS please can you give any advice thanks ...

[@lorencoen3484]

My chuck is fine but the drill is frozen light comes on but I cannot get the drill to rotate in any setting forward reverse, drill, hammer, or screw. 1 or 2 gearing? Any thoughts?

[@stefanvojnovic5323]

Dead switch or electronic, same problem but with brushless motor version

[@johndaniel375]

Question: Can I convert my Makita regular drill into hammer drill since hammer drill function is part of the gear assembly?

[@garethgedamke7348]

I would think not. The gear assembly is larger on the hammer drill and wouldn't fit the housing. Also, the hammer drill takes a lot more power to run, so the armature is larger.

I found broken Makita still work only the shelf broken n holding with tape .

How to charge 14.4 drill battery

[@stevenbell7902]

My chuck would not undo. I had to cut the gearbox to pieces to get to the shaft before it would undo. Job’s a Good’n.

[@philthunder]

That was a gearbox swap, now try repairing the gearbox and post it!

[@MegaClashcityrocker]

Don't waste your time would be my advice. I bought a gearbox, but couldn't seperate the chuck. Not amount of impact would loosen it on a DHP453. In the end , I bought a chuck as well,. It the cost was like 20% less than buying a body only replacement.

[@charlottebrace2174]

Same problem... It is a real pain

[@stephenrobb9309]

So, are you suggesting trying to remove the chuck before purchasing parts?
