View Full Version : How I Repaired my 8-Tracks

I noticed a few threads here talking about how to repair an 8-track tape so that it will play again. I have about 90 tapes from the 1970's. Some are home grown recordings.

I have a 1978 Dodge restoration project that has a factory 8-track AM/FM stereo in it and of course an 8-track in the house too. Owned the car since new.

My wife, a walking contradiction, can't understand why I won't let go of the technology, yet she has 'stuff' she has lovingly preserved since long before we were married!

Anyway, I have some tapes that use the foam reinforcement to keep the tape on the read head of the deck. Over time the foam disintegrates and may even contribute to a tape being 'eaten' by the capstan drive.

During the winter months, I have taken a number of tapes apart and replaced the splice, foil and the foam and cleaned the inside of the tape case as well. the results were very acceptable and the repaired ones are still running.

Here's what I did:

Each tape comes apart a little differently depending on the manufacturer. Often the label seals the tape and it has to be cut along the seam between the two halves in order to get the tape apart. I have resorted in some cases to leaving the label intact and simply opening the cartridge and using the label as a 'hinge' to hold it all together while I work on the inner parts.

I clean everything with Isopropyl alcohol prior to reassembly, including both sides of the splice area.

For foil, I use aluminum foil cut to size and held in place at each end with magic tape cut on a diagonal to match the foil. The backside of the splice gets another piece of magic tape and then the magic tape is trimmed so the tape does not extend beyond the outer edges of the mag tape.

For the foam, I use medium density often used in furniture, but have even used foam sponges purchased at the Dollar Store. I cut the foam to the correct width and thickness and then finally size it to the backing. (If you ever lose a backing strip (usually white) I have used a plastic coffee stir stick cut to the right length from StarBuck's, whatever.

The foam is attached to the backing with that two-sided tape used to attach plastic film storm windows. It's just about the right width. Then I cut a slice in the middle of the foam so it will straddle the post that divides the opening in the tape facing the read head.

'Purests' may cringe at this, but this repair method has lasted over 20 years now. Worked for me, your experience may vary.

This is the best stuff to use to replace the foam.

In my High School days I spent a lot of time making 8 Track tapes and custom fitting the tapes with the right amount of tape. The tapes I made were programmed so that there was never a track change in the middle of a song. The tapes may have been longer than normal and a song might appear on the tape at two or three different places but I never got a complaint. I liked to use the TDK type tapes as they were a step above the Capitals and other junk. If a tape is commercially produced it is the cheapest stuff. These tapes when doing a repair have to be tensioned correctly as the slippery tape type requires it to work correctly. The good news is that they accept a large variation. If you can get TDK cartridges and tapes then you will have better performance with your machines. Cleaning Pinch Rollers in these cartridges is still required although they get dirty very fast due to the lubricated tape. Some carts use plastic wheels for a Pinch Roller.
Since these tapes are made to ONLY go in one direction repair can be made faster when using a motorized item to run the tape when it is repaired to see if it will go all the way through. In this case I used to use my fathers drafting eraser device which had a rubber tip and was motorized. It was perfect for the job as I was able to quickly advance the tape by driving the platter that tape sat on which is what moves when it is driven inside a machine. Those were the good old days. The programs were calculated on a Hp calculator that I programmed for time calculations.
