Zenith VRF510HF issues

[audi_nicoya7]

Hey everyone so I picked up a pretty mint JVC built Zenith VRF510HF VCR that came in the original box however upon testing it I found that rewind nor backward search works and it eats the tape upon ejecting however fast forward works good and although it plays fairly well mechanically speaking the tracking is trash leading me to believe its out of alignment. I took top and bottom covers off belt looks and feels good and manually rotating the idler clutch from below I noticed that the gear in between the reels doesn't pivot to its respective reel based on the direction I rotate from underneath hence the possible reason as to why it doesn't rewind and eats tape. I know these JVC units are known for throwing parts but the clutch is still attached or so it seems. Any ideas welcome since I actually like this unit! Oh and by the way I located a service manual for it so that SHOULD also help.

Thanks!
