Our MBK-78 series of parts covers over twenty VCR models by JVC and Zenith. The on-line database has been set up to direct you to the proper rubber replacement or maintenance kit for your VCR. Even though every precaution has been taken to assure the accuracy of the database, mistakes can be made. If you have doubts about the pictured VCR being similar to yours please check the chassis photos below. If you feel that we've made a mistake, please E-Mail us and let us know.

We have two rubber replacement kits and a repair kit for these VCRs that were manufactured by JVC.

Common problems are VCR ejects cassette shortly after loading, fail to load tape into play position after cassette loads, and shuts down. Your price for our MBK-78 kit is $1.95. See photos for parts locations.
VMK-132 Maintenance Kit	This kit is a complete maintenance kit for these JVC VCRs. It contains both belts, the idler assembly and the pinch roller.

MBK-78-IC: Idler Clutch Assembly	The Idler Clutch Assembly can cause the VCR to have playback, FF, or Rew problems A defective clutch is not quite as easy to detect as a bad idler.

MBK-78P: Complete Rubber Kit	This kit is a complete rubber replacement kit for these JVC built VCRs. It contains the belt and the pinch roller.
