This tight fitting washer will help to eliminate wobbling on the head of the Bosch PBD 40 drilling machine. But! You must understand that the only way to completely remove the chuck backlash is to replace the needle bearing in the upper part of the gearbox with a graphite-lubricated bronze bushing. To do this, you will have to disassemble the PBD40 and here you will need locksmith experience. I disassembled and took detailed photos of the process to reassemble later. Sleeve dimensions 8mm x 12mm x 8mm link where i bought the bushing In photo number 4, I showed what needs to be replaced. Yes, it takes effort, but it was these two improvements that allowed me to achieve an exceptional version! On my PBD40 I achieved zero beat.
