How to repair a Makita DHP453 combi drill with a stripped gear, using a old Makita 8391D Nicad drill

These Makita DHP453 combi drills are only cheap drills and are classed more as DIY grade. But they are actually a little work horse, and can do a suprizing amount of work. The main downside is the slower RPM. Due to the abuse these drill get, they do have a habit of stripping the high gear. They are only a cheap drill and so only have a plastic gearbox. And makita does not supply this gearcase on its own. Only as a whole gearbox. To replace the whole gear box, you're talking 50 euro. Which is not worth it. The other option is to use the part from an old makita nicad drill that is no longer used. The 8391D drill actulay has the same gearbox, so you can take the gearcase from this or use the whole gearbox. #makita #tools #dhp453 #powertools #makitafix #joblot #wholeboxoftools #canhefixthem #toolrepairs #broken #fixingtools #makitarepairs #boschfix #toolbox #powertools #deandohertygreaser #toolrestoration #restoration #howto #toolfix #brokentools #toolteardown #teardown #insidetool #milwaukee #milwaukeefix #quickfix #machinerepairs #machine #brokenmachine #8391d
