Hi guys! Doesn't that anemic FF/REWIND on the NAD 6100 bug you?! It's a great-sounding deck with my all-time favorite recording level meters (so fun to look at in the dark), but that DAMNED wimpy transport motor! Well, I had enough and de-soldered the leads to the dedicated motor (it's the silver can at the rear of the cassette transport mechanism, on the top; the lower one drives the tape in PLAY), removed it. Sprayed, um, er, Radio Shack cleaner/lube into all the holes in the motor, worked the cogs back and forth for a while, sprayed it again and re-installed it. Voila! At least 40% stronger & smoother. Caig De-Oxit followed by Caig Gold would have been a much better idea but I was out. LET ALL THE EXCESS CLEANER/LUBE DRAIN OUT OF THE MOTOR before re-installing or it will drip on the belt, causing it to slip and making the tape un-ejectable! (Don't ask me how I know this). To be on safe side let motor dry overnight, and blow it out thoroughly. Re-install and feel the joy. Belt replacement:Do it while FF/RW motor is drying and you'll have much easier access. Slip belt off small nylon wheel on drive motor (this time it's the lower silver can) so that belt comes off on side closest to REAR OF CASE. Now, said belt appears hopelessly hung up around the flywheel and many, many unpleasant steps away from being replaced. Not so my friend! Gently tug the belt up on the side of the flywheel closest to the rear of the case. See that little white nylon disk and the bronze shaft going into it? That's the spot! With not much persuasion tease the belt up and THROUGH. You will find that the disc and shaft 'float', or give, slightly, more than enough for the belt to come free. No prodding or prying with foreign objects is necessary; just gently working the belt against this junction will suffice. Installation of new belt is the reverse. I used a plastic zip-tie to coax the new belt back onto the fly- and drive-wheels but you probably have a much cooler idea. Hope this helps anyone else owning the otherwise loveable 6100 and, no, I'm not a professional tech so feel free to scold me and check this procedure out with greater minds. That said, I have recorded and played tapes on it since and cannot detect anything amiss. If interest suffices I will take pics to help you through it. Cheers!
