Toshiba Model M-632 VCR giving fits

[Captainclock]

Hello everyone yesterday at work (Goodwill for those of you who are not aware that I work there now) I found a 1992 vintage Toshiba Model M-632 4-Head Hi-Fi VCR and I went home and put it in the basement and then today I got around to testing it out to see if it worked or not (I was planning on using it as a spare VCR for my LCD Projector Setup in my Basement in case my Hitachi 4-Head Hi-Fi VCR from the late 1980s bites the dust) and anyways it didn't work right this VCR and I suspected that it was bad belts and took and opened it up and sure enough all of the belts were stretched and getting ready to turn to goo, so I replaced the main drive belt with another drive belt I had laying around that happened to fit it, but the only problem is that the other two belts (the secondary drive belt and the loading mechanism drive belt that sits in the back of the VCR were sizes that I didn't have except in the smaller audio cassette tape player mechanism sized belts so I put those in but apparently they're too small thickness wise to develop enough torque to get the loading mechanism to run because when I try to load a tape into the VCR the motor just keeps spinning but it doesn't turn the pulley that drives the loading mechanism, I had found a drive belt that was a little bit thicker than the other belt I had been using (but not the same thickness as the original belt) and I installed that and it seems to be able to turn the pulley without any problem but now it seems that for some reason when I insert a tape into the VCR the tape will load into the VCR but the loading mechanism that should load the tape into the heads and play the tape isn't responding now, and its rather odd because the VCR when its powered on initially the POST test that the VCR goes through to make sure the VCR is in proper running order passes and the VCR stays on although the VCR then powers itself off after about 45 seconds after the POST process and then I turn it back on again and it stays on but then that's when the VCR is unresponsive to a tape being inserted and the play button being pressed.

Anyways any ideas as to what's going on with this machine, or anyone have any experience with this particular model? By the way its a Samsung made machine that Toshiba put their name on (as well as some of their own parts and chips in.)
Sorry for the long winded story about this machine but it was the only way I could explain what was going on with this machine.
