Review on Replacement Aluminum Shell Makita Grinder by Travis Filippi

Mounting hardware not included so be careful with soft factory screws. All I had to replace was the head, so I tried to do just that. Reusing the factory seal between the grinding wheel and the head and reusing the factory drive bracket. The head was a perfect fit, the grease found on the factory head was reused for the drive mount and the drive mount was fully adjusted (not quite flush but within 1/16" all around). terrible rattle. I took it apart again and found that with only this factory fitted head, the nut on the pinion was marked and the seal/shield on the drive gear was deformed. The drive pin never engaged the drive gear, so it never turned. I didn't think cheap Chinese ones could be of any lower quality than factory Makitas, but they are impressively smaller.
