I am currently restoring a Racine 14" hacksaw. The only information I have is a small metal tag which reads: (8) USN 038292. Do you have any repair or parts manuals or any other information which may help. The part I am having problems understanding is the hydraulic pump function. I have already removed and disassembled, cleaned and reassembled the piston (pulls down blade assembly). The part I have not figured out is the how the pump works. There is a cam wheel on the main drive shaft which appears designed to press the pump assembly but the cam does not come into contact with any other parts during a complete rotation. I hope that I have not confused you with my non technical explanation,
Thanks
Thanks
