Here are the instructions for the Hot Wheels Road Trials Set.
So there you have it. Instructions for the 1970 Hot Wheels Road Trials Set.
It’s still fast. Still fun.
Every car owner knows that regular maintenance and periodic repairs are an integral part of keeping your vehicle on the road. However, for kids, the mindset is more one of running your toy car into the ground and then getting a new one. But in 1970 Mattel took a different approach by letting the young enthusiast work on his car to keep it running “faster than ever”!
The Tune-Up Tower provided the back bone for Hot Wheels maintenance. The Road Trials Set planted the tower inside an oval track powered by a single-lane Rod Runner.
That meant you could bring a slower running car in for an evaluation and adjustment, then send it out on the track for a “trial” run to see if it moved faster.
This time around I am working with 3 open wheel redline cars that Mattel released in 1969.
All 3 of these machines ran in the 1968 Indy 500.
Dan Gurney piloted the #48 Indy Eagle.
He drove a spectacular race and finished second behind race winner Bobby Unser.
Joe Leonard grabbed the pole position in his #60 Lotus Turbine.
He was leading the race with only 9 laps to go when a fuel shaft broke and put him out of competition. He finished 12th for the day.
Every Hot Wheels Lotus Turbine car came with a #70 sticker sheet. The original #70 Lotus Turbine was driven by Graham Hill.
Hill won the Indy 500 in 1966 but finished 19th during the ’68 race.
Here’s some pictures of the Road Trials Set in action and a YouTube video to bring it all to life.
So there you have it. The 1970 Hot Wheels Road Trials Set with Tune-up Tower and Rod Runner. Making Hot Wheels still fast. Still fun.
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.
It’s time for a tour of the 1970 Hot Wheels Tune-up Tower.
We have 3 floors to drive thru.
Today we’ll head into the Tune-Up Tower driving a ’73 Firebird Trans-Am.
The main feature on the top floor is the dyno-meter treadmill.
Here’s a little bit more detail on driving thru the Tune-Up Tower.
So there you have it. A drive-thru of the 1970 Hot Wheels Tune-Up Tower.
It’s still fast. Still fun.
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.
A great way to tune hi-performance cars is to put them on a dynamometer.
The Hot Wheels Tune-Up Tower treadmill is the all-wheel drive type. Unfortunately, the treadmill often malfunctions.
The number one problem with the treadmill is slippery grime on the rubber roller of the drive shaft.
The number two problem with the treadmill is a missing torsion spring to hold the roller in place that drives the treadmill.
Here’s my YouTube video on how to disassemble, clean and repair the treadmill on a Tune-Up Tower.
So there you have it. The 1970 Hot Wheels Tune-Up Tower treadmill. Getting it to work is another step in making Hot Wheels still fast. Still fun.
Now that we’ve got the main motor running, it’s time to start looking at the treadmill apparatus. First up is the Dyno-Meter head unit.
This unit contains the blue needles that mark out the Wheel Speed and Wheel Drift on the Dyno-Meter panel. It also consists of the orange arms that hold the car on the treadmill.
What’s the most common problem with these needles and arms? Some ham fisted kid back in the early 70’s decided to see how far he could bend them.
Here’s my video on how to fix a wonky Dyno-Meter head unit.
So there you have it. The 1970 Hot Wheels Tune-Up Tower Dyno-Meter head unit fixed and ready to go.
Up next, how to get the treadmill running so we can keep Hot Wheels cars still fast. Still fun.
