How is the healt of this piece is it worn also the other part that will work together with this part must be replaced

Or hows the part connexion 221347-1 spiral bevel gear on the 152335-6 cilinder liner ?? i think its economic not interesting for repair because of the high prices. and the problem of discontinued parts in the prospect

Here is a parts diagram. If that still doesn't help you call Makita's customer service at 800-462-5482.

as long as the chuck is used for a hammer drill and the thread size is exact yes it will. I believe the thread is 1/2-20 and also make sure the chuck has a hole in the center for the reversing screw to keep it from loosening up. Let me know if you need more assistance. The thread size is usually stamped on the side of the chuck. Makita sometimes used a metric thread.

Sounds like the chuck is worn, happens frequently when used often. Here's the link to Makita, their contact info should get you some answers as to what part number is needed as well as the closest location to you for service if required. Hope this helps.

Check out the split drawing on this page.
If your makita does not have any outside accessible brush caps, you need to dismantle it.
lay it on the side, where the side with the screws securing the to halves together is facing up.
Remove all screws (some may be hidden under labels etc.) Gently pry the halves apart, locate the brushes disconnect their leads if any, and remove. Install new brushes and make sure the move freely, and that they are springloaded when in place. Gently rotate the rotor to ensure everything is ok . Reassemble and test drill. If the brushes leaves long streaks of noticeably large sparks, something has gone wrong or the rotor was damaged in the first place, causing excessive wear.

Exchanged Makita HP1640 hammer drill for a new one. The 2nd drill did the same thing in under an hour!! Will return for refund. Instructions say the Forward/Reverse switch must be in a full up or down position for the Hammer/Rotary switch to move; well, it is and the Hammer/Rotary switch still stops at a 1/2 way point between modes. Although I can still use the drill, instruction warnings say not to because it may potentially burn out the motor. I'll have to go with a different brand this 3rd time around. It seems to be a design flaw.

you need to get that service,
the grease causes the hammering.
and probably too much pressure was applied
to it.

oh I hate when that happens. ushally its due to not being lined up right inside the unit. happens with my cheaper drills more so then not.

I ushally just secure the bit into my vice, and then tap the the key with a hammer to loosen the threads..

sounds like she might need a bit of oil I ushally use air compressor oil just a couple drops work for me.

tap the 3 jaw with hammer not too hard. then the sleeve clockwise
