VODCACA Secondary Variator Pulley Kit for John Deere 100/105 Series - GT79244/MIA12482, Heat-Resistant Direct-Fit

VODCACA's GT79244 / MIA12482 secondary variator pulley kit is a direct-fit replacement for John Deere 100 and 105-series lawn tractors, restoring secondary transmission performance without modifications.

If your John Deere D105, E100, X105 or X106 tractor is slipping, making unusual noises, or failing to shift smoothly, a worn secondary variator pulley assembly may be the culprit. This replacement kit (also referenced as RT400, MIA12025, MIA12656, MIA13114, AUC10266) is designed to meet OEM dimensions and materials so you can return the sub-transmission to reliable operation quickly.

How does this pulley kit restore transmission performance?

The kit replaces worn or damaged variator pulley components that control belt tension and gear ratios in the secondary gearbox. By using parts built to the correct tolerances, the pulley restores smooth shifting and prevents slippage under load.

• Direct-fit for John Deere 100/105 series—no aftermarket modification required
• High dimensional stability to match factory settings
• Replaces RT400 and several OEM reference numbers for compatibility

What materials and protections does the kit use?

VODCACA builds the kit from durable, heat-resistant materials that resist abrasion, dust ingress and water exposure. The components are specified to withstand typical lawn tractor operating conditions and sustained heat up to rated limits.

• Heat-resistant construction rated for sustained high-temperature exposure
• Waterproof and dustproof design to protect moving parts
• Shock- and abrasion-resistant finishes to extend service life

Which John Deere models and part numbers is it compatible with?
