Dusting off your old Scalextric set can bring back a rush of childhood memories. However, if your cars are making a loud whirring noise and struggling to move, you’re likely facing a common issue: stripped gears. Don’t worry, repairing your Scalextric car and getting it back on track is often a straightforward process. This guide will help you identify the problem and get those wheels turning again.
Identifying the Problem: Stripped Gears
The “big coggy thing” you’re referring to is known as the spur gear. This crucial component sits on the rear axle and meshes with a smaller gear (pinion gear) on the motor shaft, transferring power to the wheels. Over time and with enthusiastic use (or perhaps a few crashes!), the teeth on this plastic spur gear can wear down or strip completely.
The telltale signs of a stripped spur gear are a loud whirring or grinding noise coming from the car, often accompanied by very little or no movement. This happens because the motor is spinning, but the damaged gear is no longer effectively engaging with the axle to drive the wheels. If this sounds familiar, gear replacement is likely the solution for your Scalextric car repair.
Finding Replacement Gears for Your Scalextric Car
The good news is that replacement spur gears are readily available for most Scalextric models. Knowing what they are called (“spur gears”) is the first step in your search. You can find these parts at online retailers specializing in Scalextric and slot car spares. A quick search for “Scalextric spur gears” or “slot car spur gears” will bring up numerous options.
When ordering, ensure you select gears that are the correct size and tooth count for your specific Scalextric car model. While many gears are standard, it’s always best to double-check compatibility if possible. Purchasing a pack of gears, as you suggested, is an excellent idea for future repairs and ensures you have spares on hand.
Simple Scalextric Car Gear Replacement
Replacing the spur gear is generally a simple task that requires minimal tools. Typically, you’ll need to remove the car’s body shell to access the chassis. The rear axle assembly will then be visible, with the spur gear sitting on the axle.
Depending on the car model, the axle may be held in place by clips or bearings. Gently remove the axle, slide off the old stripped gear, and replace it with a new one. Reassemble the axle, ensuring everything is correctly aligned, and test your car. With a new spur gear installed, your Scalextric car should be back to running smoothly and quietly, ready for racing once more.
Conclusion
Repairing a Scalextric car with stripped gears is a common and easily fixable problem. By identifying the spur gear as the culprit and sourcing readily available replacement parts, you can quickly bring your beloved Scalextric cars back to life. Enjoy the fun of slot car racing without the frustrating whirring noises and sluggish performance!
