How To Shim A Gearbox

A gearbox is a device used to increase or reduce the speed of rotation of a power source. It does this by providing gears which mesh with each other, providing different ratios of speed and torque. There are many types of gears, and they must be fitted carefully in order to function correctly. If the gears are not properly aligned, the gearbox will not work as intended and may even cause damage. This is where shimming comes in. Shimming is the process of adding small pieces

How To Shim A Gearbox

There are a few methods that can be used to shim a gearbox, depending on the make and model of the gearbox. One common method is to use washers or shims made from metal or plastic. The washers or shims are placed between the gearbox housing and the engine block, in order to adjust the clearance and ensure that the gears are meshing correctly. Another method is to use a sleeve made from a flexible material, such as rubber or neoprene

-Gearbox -Shims -Screwdriver -Socket wrench -Torque wrench

  • Remove the screws that hold the cover in place
  • Locate the gearbox that needs to be shimmed
  • Inspect the gears and identify which one is out of alignment
  • Use a shim of the appropriate thickness

-Check the gearbox for damage and repair as necessary -Clean the gearbox and all of its components -Lubricate the gears with a light oil -Install the shim(s) between the input and output shafts, adjusting them as needed so that there is no play in the gearbox


Frequently Asked Questions

How Do You Shim A Gearbox?

To shim a gearbox, you would need to remove the cover and find the shims. You would then need to measure the thickness of the shims and select the correct ones. After that, you would need to remove the old shims and install the new ones.

What Does Shimming Gears Mean?

Shimming gears is the term used to describe the process of adding a thin layer of material between two gears in order to correct for any misalignment.

Why Are Shims Used In Gearboxes?

Shims are used in gearboxes to adjust the clearances between the gears and the casing. This ensures a smooth and efficient transmission of power from one component to another.


To Review

Shimming a gearbox is a process that can help to ensure that the gears are properly aligned and functioning as they should. There are a few different methods that can be used to shim a gearbox, and the most appropriate method will depend on the specific gearbox and its configuration. Generally, shimming involves adding or removing material from certain locations around the gearbox in order to adjust the spacing between the gears.
