Introduction

There are many components to a convertible top. Each individual part of the frame has a specific job, and when they work together, the convertible top will operate flawlessly. Worn or damaged components will need to be identified and repaired before a new top can be fitted.

Before any work on the convertible top begins, a thorough inspection of the project should be done. This evaluation will help determine what will need to be done to restore the convertible top to peak working condition.

A visual inspection of the convertible top frame and the hydraulic system must be performed to determine any abnormalities or obvious broken or worn components that need to be addressed and restored. Start by looking for any tears in the convertible top fabric. This will indicate a potential underlying problem with the convertible top frame. Also look for bulges or distortions in the shape of the convertible top. This may reveal a bent component in the convertible top frame. A lumpy header bow is a strong indicator that there is corrosion on the header bow that will need to be repaired before the new top can be installed.

It is my recommendation that when the convertible top has obvious damage or it is missing parts, it is best to have another person help guide the top so that it will not cause any additional damage as it is being raised or lowered. Once the top frame has been stabilized, a proper repair can be made to correct the defect in the frame.

After the visual inspection, you should then operate the top and listen to it while it is being raised and lowered. Determine if the convertible top is to be operated manually or it is a power-assisted top.

If the top can be operated, unlatch the top from the windshield and lower it into the well compartment. Listen to the convertible top frame as it is being operated. You will notice that manually operated tops may creak when they are raised and lowered. The creaking from the assist springs expanding or contracting are normal sounds to hear. A power top should make a dull whirring sound.

Sharp scratching or grinding sounds are not normal, and you should slow down and try to locate the cause of the noise. This noise is an indication that there may be a bent or broken component of the top frame. You will need to identify the cause of the noise so that a proper repair can be made.

Look for any shinny spots on the frame where parts may be rubbing. Also look at each pivot point and verify that the rivet or fastener has not failed. Compare the left frame rail to the right and make note of any differences. When the left and right frame rails show no irregularities, work can proceed. If variations are present, then repairs will need to be made to the frame so that it can operate correctly.
