CLUTCH

Use Mopar® brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use
fresh, clean fluid from a sealed container at all times.

Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow
additional air to be drawn into the system. Check the cylinder fluid level frequently and add fluid as needed.

1. Verify fluid level in brake master cylinder, top off brake fluid as necessary.

2. Open bleeder (1) on slave cylinder (2) and install a length of clear hose to divert fluid into suitable

container. Push and hold clutch pedal down then close bleeder. Repeat this step several times.

3. Remove slave cylinder from transmission.

4. Hold slave cylinder with actuator rod pointing down and open bleeder. Push cylinder actuator rod in

completely then close bleeder. Repeat this step several times.

5. Remove drain hose and replace dust cap on bleeder and install slave cylinder on transmission.

6. Actuate clutch pedal 25 times, then start engine and verify clutch operation and pedal feel.

If pedal feels spongy or clutch does not fully disengage, air is still trapped in the hydraulic circuit and
must be bleed again.

PRESSURE BLEED CLUTCH HYDRAULIC CIRCUIT

Follow manufacturers instructions carefully when using pressure equipment. Do not exceed the tank
manufacturers pressure recommendations. Generally, a tank pressure of 15-20 psi is sufficient for bleeding.

Fill bleeder tank with recommended DOT 3 fluid and purge air from the tank lines before bleeding.

Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or
drawing air back into the system. Use adapter provided with the equipment or Adapter 6921.

NOTE:

When pressure bleeding system slave cylinder must be removed and actuator
rod pointing downward to remove trapped air.
