The new optional C-hub suspension is a great new tuning option to set up your T1 for different racing conditions.Before you mount the new C-hub suspension,dismount the entire front suspension on the car,but keep the front bulkheads mounted on the chassis.
1. Thread a #309358 (SB M4x8)downstop adjustment screw into the front lower arm.It must protrude 2.0 mm below the arm.This screw needs to be accessible from the top of the arm.
2. Thread a #309351 (SB M3x4)pivot pin set screw into the arm. Thread it just enough so it will stay in the hole; don â™t let it thread into the pivot pin area.
3. Thread a #309354 (SB M3x8)shock mounting screw into the hole located at the front outside of the arm.It must protrude 3.0 mm.
Repeat for the other arm, making sure to mirror the screw placement. |

1. Use the coupling from dismounted front suspension,lightly grease it and insert it into the drive shaft joint.
2. Slide the drive shaft joint into the #305310 wheel axle,aligning the cross holes.
3. Insert a #309452 cross pin (P 2x10)through the aligned holes in the coupling and wheel axle.Make sure it is evenly spaced on both sides of the wheel axle.
4. Install a #305240 plastic cap onto the drive shaft pins.First insert one hole of the plastic cap over a pin,then stretch the other hole over the other pin.
Repeat for the other axle. |

1. Press two #302294 nylon bushings into the steering block until they seat firmly.
2. Slide a #309054 (BB 10x15)ball-bearing onto the wheel axle.
3. Insert the wheel axle into the steering block until the bearing seats in the nylon bushing.Note the direction of installation from the diagram.
4. Slide another #309054 (BB 10x15)ball-bearing onto the wheel axle.Press the bearing into the steering block,making sure it seats properly in the nylon bushing.
5. Fasten the wheel axle to the steering block by installing a snap ring in the groove in the wheel axle (near the drive shaft joint).To make installation easier,place the hex portion of the wheel axle flat on a table.Put one end of the snap ring into the groove on the opposite side of the wheel axle cutout,and use a slotted screwdriver to work the rest of the clip into the groove.
Repeat for the other side. |

1. Insert two #302293 C-hub nylon bushings into the C-hub.Orient the nylon bushings so the ridges are to the inside of the C-hub.
2. Insert two #302290 C-hub bushings into the already seated nylon bushings.
3. Insert the steering block assembly into the C-hub.Insert the left assembly into C-hub marked ,and the right assembly into C-hub marked R.
4. Pass two #309335 screws (SH M3x10)through the bushings,and thread into the top and bottom of the C-hub.
5. Thread a #309351 screw (SB M3x4)into the bottom of the C-hub.Do not tighten fully.
6. Place a #309318 washer (C 3.2)on a #302650 ball end,then thread the ball end into the top of the C-hub. |

1. Mount two #303240 balls to the rear of the #302093 front shock tower using two #309333 (SH M3x6)hex screws.Mount the balls to the middle holes as shown.
2. Mount the front shock tower to the bulkheads using two #309333 (SH M3x6)hex screws.
3. Insert the assembled C-hub steering block into the arm.Align the hole in the bottom of the C-hub and holes in the arm.
4. Slide a #307220 pivot pin through the aligned holes.The flat spot on the pivot pin must be towards the bottom.Tighten the #309351 screw (SB M3x4)until it is tight on the pivot pin.
The steering block assembly should move freely.
5. Position the front suspension assembly in the front bulkhead. It should seat between the two plastic lower suspension holders. The pivot pin set screws should be accessible from the large access holes underneath the chassis.Place the driveshaft plastic cap into the diff outdrive slots.
6. Align the holes in the arms with the suspension holders and slide a #307212
lower front pivot pin through the aligned holes. The flat spot on the pivot pin must
be towards the rear and facing the bottom.
7. Tighten the #309351 pivot pin set screw (SB M3x4)in the lower arm onto the flat spot on the pivot pin.
Repeat for the other side.
Check the arms for free movement. |

Snap the turnbuckle ball joints onto the balls on the steering blocks and the balls on the shock tower. The suspension arms must be able to fall freely when lifted up then dropped.If there is any binding that prevents the arm from falling freely, remove the ball joint from the ball and lightly squeeze the ball joint with a pair of pliers. Remount the ball joint and check the arm movement again.
Repeat this process until there is no more binding. |
