Default Re: JVC HR-D120MS - Squeaking noise when lacing up

Thank you. One thing I forgot to point out is that even if you've marked the position of the loading rings in relation to the chassis, the loading mechanism might still get out of alignment after putting it together. In that event, you'll need to slacken off the loading motor block so that you can move the P2 and P3 guides freely and individually, and once they are aligned/timed correctly, you can then re-fasten the loading motor block with its gears and verify the alignment by turning the loading pulley by hand. The tape guides should reach their V-blocks at exactly the same time, otherwise the mechacon microcomputer will go haywire and run the loading motor for way too long, and that might cause the circuit protector of the loading motor's power rail to blow up.

Regards
