How to adjust a Bendix Drive?

Hey there! As a supplier of Bendix Drives, I've seen my fair share of questions about how to adjust these crucial components. In this blog, I'll walk you through the process step by step, so you can get your Bendix Drive working like a charm.

First off, let's talk a bit about what a Bendix Drive is. It's a key part of a starter motor, responsible for engaging the flywheel when you turn the ignition key. This engagement transfers the power from the starter motor to the engine, getting it up and running.

Before you start adjusting your Bendix Drive, it's important to gather the right tools. You'll need a set of wrenches, a screwdriver, and a feeler gauge. These tools will help you make the necessary adjustments accurately.

The first step in adjusting a Bendix Drive is to remove it from the starter motor. This usually involves removing a few bolts or screws that hold it in place. Be careful when doing this, as you don't want to damage any of the components. Once the drive is removed, you can inspect it for any signs of wear or damage. If you notice any issues, it might be a good idea to replace the drive rather than trying to adjust it.

Next, you'll want to check the clearance between the drive's teeth and the flywheel. This is where the feeler gauge comes in handy. Place the feeler gauge between the teeth and the flywheel and check the measurement. The ideal clearance can vary depending on the specific model of the Bendix Drive, but generally, it should be within a certain range. If the clearance is too large or too small, you'll need to make adjustments.

To adjust the clearance, you'll typically need to loosen a lock nut and turn an adjusting screw. Turning the screw clockwise will decrease the clearance, while turning it counterclockwise will increase it. Make small adjustments and keep checking the clearance with the feeler gauge until you reach the desired measurement. Once you're satisfied with the clearance, tighten the lock nut to secure the adjustment.

Another important aspect of adjusting a Bendix Drive is ensuring that it engages and disengages smoothly. You can test this by manually rotating the drive and checking how it interacts with the flywheel. If it doesn't engage or disengage properly, there might be an issue with the springs or other internal components. In some cases, you may need to disassemble the drive and clean or replace these parts.

Now, let's talk about some common problems you might encounter during the adjustment process. One issue is a noisy Bendix Drive. This could be due to a variety of reasons, such as worn teeth, a misaligned drive, or a problem with the bearings. If you hear a grinding or rattling noise, it's important to address the issue as soon as possible to prevent further damage.

Another problem is a drive that fails to engage or disengage. This could be caused by a faulty solenoid, a weak spring, or a problem with the electrical connections. Check these components carefully and make any necessary repairs or replacements.
