The crown wheel and pinion is an essential part of a vehicle's differential, which controls the torque that is sent from the transmission to the drive wheels. It is important to routinely check and service this component for optimal performance and safety. But how do you go about this job, and is it something you can do yourself?
Step 1: Remove the Axle Shafts and Differential Cover Plate
The first step in servicing a crown wheel and pinion is to remove the axle shafts. Once you have done so, you can then remove the differential cover plate. This will allow you access to the gears inside of the differential. Of course, you will need to drain the oil from the rear axle first before attempting any work.
Step 2: Inspect the Gears for Wear or Damage
Once you have access to the gears, it is important to inspect them for any signs of wear or damage. If there are any damaged teeth or other signs of wear, then they must be replaced before further work can be done.
Step 3: Install New Bearings if Necessary
After inspecting your gears, it is also important to check your bearings for any signs of wear or damage. If they are worn or damaged, they must be replaced with new ones before continuing with the rest of the work.
Step 4: Reassemble Your Differential and Add Oil
Once you've inspected the parts and replaced them if necessary, you can reassemble the differential. Replace your axle shafts and refit the differential cover plate. Always make sure that you add high-quality lubricant and fit new gaskets in between the cover plate and the housing.
What to Bear in Mind
A well-serviced crown wheel and pinion set will provide maximum efficiency for controlling torque from the transmission to drive wheels in a vehicle's differential system. Routine servicing should occur according to the manufacturer's recommendations to ensure optimal performance.
You may be able to perform this work at home if you have the right tools, the patience and know what you're doing. Remember, you need to be able to assess the condition of the crown wheel and pinion, the bearings and all associated parts to know whether you should replace them or not. If you ever feel uncertain or unsafe while performing this kind of work, be sure to seek professional help from an automotive mechanic who specialises in differentials.
