Complete Belt Kit for Kenwood KX-W4050

hi I'm - another cassette deck yeah I've got four cassette decks are discovered and none of them are working I wanted to record some tape so rather unfortunate this one is a two deck model I think it's quite a late model by the looks of it but having a bit of trouble with fast forward rewind and fast forward working now that's good but this one's got two belts interestingly the secondary belt which use of fast forward and rewind that one's loose but the one on the flywheels is fine but remain from my head is I try to put it into record and I couldn't side a bit of a guess can I get record out again but the micro process control deck there is some contact here which sense whether the record prevention tabs being chrome dioxide and where the cassette is there and I kept operating them and eventually it worked but I think we need a bit of contact cleaner because I clap it put often it drop
