YOKSD302G MR-4TCSD Gear Case Overview

The YOKSD302G transmission gear case is an SD-series replacement unit produced in a graphite mixed resin to deliver a balance of reduced mass and increased rigidity for RC touring car transmissions.

This kit includes the main case and cap plus the screws required for installation so it can replace worn or damaged housings on MR-4TCSD transmission assemblies without chassis modification. The graphite mixed resin lowers weight while keeping stiffness where the case seats bearings and mates to the gearbox mount.

When fitting the replacement case, check input and output shaft alignment and confirm bearing seating before final assembly; use the supplied screws and apply moderate torque to avoid distorting the resin. This part is intended for scale RC use only and is not suitable for full-size vehicle applications.

  • Transmission case Mission Case - 1 pcs
  • Transmission case cap Mission Cap Case - 1 pcs
  • 3 x 12mm tapping screw Tapping Screw - 4 pcs
  • 3 x 8mm plate tapping screw Flat Head Tapping Screw - 4 pcs

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this replace my MR-4TCSD case without trimming the chassis?

Yes. The component is specified for MR-4TCSD compatibility and is intended to swap in without chassis modification when installed correctly.

What hardware is supplied in the package?

The kit ships with the transmission case, the cap, four 3x12mm tapping screws and four 3x8mm flat head tapping screws as listed in the packing section.

How tight should I torque the screws during assembly?

Use a light to moderate torque setting consistent with resin components; overtightening can warp the housing. Tighten incrementally and check bearing seating as you go.

Any tips to avoid distorting the resin during installation?

Confirm shaft alignment and bearing fit before final tightening, and alternate screw sequence to draw the halves together evenly to reduce the risk of local deformation.
