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.
The Tune-Up Tower has it’s dynamometer testing unit on the top floor. Cars come into the tower from ground floor track. To get up to the testing area the cars are lifted up by an elevator.
Problem is, the elevator is often malfunctioning or not working at all. Fortunately, Mattel engineered these towers so well that getting them to work properly again requires little more than a thorough cleaning of a couple of parts.
The most critical part is the drive roller on the top of the elevator’s back side. It pops out on the gear side.
The grime and debris on the rubber roller have to be completely removed otherwise the belt will just slip.
I find that a Mister Clean Magic Eraser does a great job.
The second piece that needs cleaning is the plastic drive belt itself. Again I use a Magic Eraser to gently clean the dirt and stains away.
If cleaning the drive roller and the drive belt doesn’t get your elevator working right…take it apart and clean them again. Usually the drive roller is the problem at this point. Every time my cleaning got the drive roller back to showroom condition, the elevator functioned like it was suppose to.
Here’s my YouTube video to walk you through some of my elevator fixes.
So there you have it. The 1970 Hot Wheels Tune-Up Tower with properly functioning elevator. Now we’re ready to make Hot Wheels still fast. Still fun.
