Shim Sets
Shim Sets for Precise Gearbox Adjustment
A shim set is used to correctly align the gears within an AEG gearbox. By making minimal distance corrections between gears and gearbox shell, friction is reduced and the drivetrain runs smoothly and efficiently.
Within this category, you will find shim sets from Guarder and G&G, supplemented with models from Element and Epes. These parts are part of AEG Gearbox Parts and are essential when installing new AEG Gear Sets.
Why is correct shimming important?
- Less friction between gears
- Less wear
- Quieter operation
- Better efficiency
Incorrect shimming can lead to noise, increased resistance and premature gear wear. A well-shimmed gearbox runs more smoothly and puts less strain on the motor.
For optimal performance, shimming must be correctly matched to your configuration within Motors & Pinion Gears.
Thickness and Material
Shim sets usually consist of several thin metal rings in different thicknesses.
Common features:
- Different thicknesses (e.g. 0.1 mm – 0.3 mm)
- Hardened steel construction
- Precision-cut rings
- Compatible with standard AEG gearbox shells
By using combinations of different thicknesses, each gear can be positioned accurately and individually.
Shimming and durability
Correct shimming ensures:
- Even tooth load
- Less heat generation
- Better power efficiency
- Longer gear life
When installing new gears, motor or bearings, re-shimming is highly recommended.
What can you find in this category?
- Steel shim sets
- Various thicknesses
- Upgrade adjustment components
Shim sets are suitable for players who want to professionally adjust and optimise their gearbox.
Frequently asked questions
What exactly does a shim set do?
It positions the gears correctly within the gearbox.
Do I always have to re-shim with new gears?
Yes, this is strongly recommended when replacing AEG Gear Sets.
Can incorrect shimming cause damage?
Yes, this can lead to tooth breakage or increased wear.
Do I need special tools?
Accurate measurement and experience are important for optimal adjustment.
With a correct shim set, you can optimise the efficiency, durability and smooth operation of your AEG gearbox.
