Ultra-Duty™ Starters from Quarter Master are hand assembled for tons of torque and great reliability. Here are a few tips for installing one on your car for best results.
If you have a high-quality starter like an Ultra-Duty™ unit from Quarter Master, it should provide you years of reliable service without any issues. You can practically set it and forget it. But getting the installation right is critical, and to help you nail that, we’ve got a few tips for you.
Quarter Master Ultra-Duty™ Starters are hand assembled and among the most durable starters you will find anywhere. They produce extremely high torque to spin over even the most high compression engines and will work with both 12- and 16-volt systems. This makes them very popular with racers who simply cannot afford a failure. And in fact, this reverse rotation unit is going onto a Dirt Late Model race car which has already been outfitted with a Quarter Master bellhousing and flywheel. But the same installation tips we’re going to tell you about will also work in practically any application.
Making use of a remote solenoid to send power to the starter is almost universal on race cars. It means you don’t have to run your power wires from your instruments all the way down to the starter, and it also simplifies installation and removal. Plus, a remote solenoid means you don’t have a wire attached to the starter that’s constantly hot.
Installing the jumper is simple. But the included jumper screw is too large for the hole in the spade terminal. The fix is easy, just chuck up a 1/8-inch bit in a drill and open the hole up. Now you can remove the nut from the unused stud, slide the jumper in place and secure it to the spade terminal with the included hardware.
With the jumper installed, all that’s left to do is install the starter on your car.
For reverse mount applications like you see on this Dirt Late Model, the ultra-lightweight magnesium bellhousing from Quarter Master includes a machined aluminum plate for securely mounting the starter. It also does a great job of precisely locating the starter relative to the flywheel so that you get the correct gear mesh for great component longevity.
The end of the starter has a machined collar that precisely fits the aluminum mounting plate on the bellhousing. Once the starter is in, it’s just a matter of tightening up the three bolts in our case. Different applications will use different fasteners, but Quarter Master provides the correct torque for each in the included instructions.
Do, however, take a moment to ensure that with the starter disengaged you have approximately 0.100 of an inch (give or take 0.040″) between the starter pinion and the ring gear. This is so the starter has enough room to completely disengage and separate from the ring gear after the engine fires up.
Finally, install a power wire to your remote solenoid. Make sure the power wire is large enough to carry plenty of power to the starter. And then attach the other end to the same terminal post you previously installed the jumper on. Remember, this post isn’t a hardened steel bolt, so use just enough torque to secure the nut. If necessary, use a few zip ties to secure the power wire so it won’t be flopping around underneath your car.
And that’s it. You’re done. The Quarter Master package is straightforward and easy to work on. All that’s left to do is to fire up the engine and go racing.
