1970 Hot Wheels Tune-Up Tower elevator quick fix

Every Hot Wheels Tune-Up Tower fix, for the most part, simply requires a thorough cleaning of the electrical contacts, the treadmill pulley and the elevator drive belt mechanism. Although this will restore most of what ails a Tune-Up Tower, I found that the elevator mechanism can still be baulky, usually when going up and especially when carrying a car.


The problem centers on the brown staining of the plastic elevator belt.  It’s some kind of oxidation, possibly related to sunlight, moisture and dust, and this stuff is slippery. Fortunately, I’ve come up with a quick fix for this elevator problem.

The answer is friction tape applied to the rubber drive roller. (By the way, the rubber drive rollers that I have seen still seem soft and useable. So, as long as it is clean, I don’t think the rubber part itself is the issue.)


Interestingly, you don’t have to wrap the entire circumference of the drive roller to get the elevator mechanism working. I found that a little bit of friction tape covering 1/4 to 1/2 the drive pulley would fix the problem. I suspect that this is variable and you may need less or more friction tape to get your Tune-Up Tower elevator working right.

Here’s a short video on this quick fix.

So there you have it. The 1970 Hot Wheels Tune-Up Tower elevator working properly with just a little bit of friction tape.


1969 Hot Wheels Automatic Lap Counter – quick fix

The 1969 Hot Wheels automatic lap counter is a cool device for…well…counting “lap after lap” action.  It’s a neat design that reminds me of a race track control tower where someone is watching and recording all the events.

Primarily, it came with Super-Charger sets.

But it could be used anywhere.  I find them quite useful on orange track Sizzlers sets where they count laps and slow cars down for upcoming hills or curves.

It’s a straight forward device that uses a swingarm to trigger each lap count.  The problem is, most automatic lap counters sold on eBay, Craigslist, and your local garage sale don’t work properly.

Typically, the one’s counter (0 through 9) works fine.  But the ten’s counter usually doesn’t work at all.  I’ve noticed this pattern even on eBay sales where the description says, “this automatic lap counter works!”

The only chance you have of getting a fully functional automatic lap counter is when the one’s column is showing “0”.  If an automatic lap counter has been stored for the past 40 plus years with the one’s column showing “1, 2, 3…or 9” then the little plastic retainer that engages the metal clip against the ten’s column has been stretched out of shape and no longer works properly.

Fortunately, the fix for this is quick and easy.

You need a small, rubber “O” ring, about the size of your little finger.  These are readily available at hardware and automotive centers.

Slide the “O” ring onto the swing arm of the lap counter.

Push it up the swing arm.

The final position is on the little plastic retainer just below it’s cross piece.

This reinforces the plastic retainer and allows it to now engage the metal clip against the ten’s column when the counter comes round to it.

When storing an automatic lap counter you want the plastic retainer mechanism at full rest and not under pressure.  This is achieved when the one’s column is showing 0.  It doesn’t matter what the ten’s column is showing.

When the one’s column is on the 0, the metal clip that moves the counter numbers is sitting in an open recess on the one’s column side which is white in color.

The recess in the one’s column is white in color. The right side of the metal clip is resting in it between the 2 and 3.

Here’s a look at my YouTube channel which demonstrates the “quick fix”.

There you have it.  The 1969 Hot Wheels Automatic Lap Counter.  It’s easy to fix.  It’s still fun.
