Description

Driftmotion Hydraulic Release Bearing Kit For R154/V160.

This bearing kit can be used with Clutch Masters or OS Giken twin disc kits, and many other brands. It comes with shims to adjust the free-play clearance from the release bearing to the diaphragm spring, The spacer length can be customized to fit different clutch applications on a 1JZ, 2JZ or 7M engine with an R154 or V160 transmission. Please specify the type of transmission in the drop down menu. Triple or Quad OS Giken requires an additional billet spacer, which is why there is an additional cost for those.

The AR5 option is only for when you are using the original GM front bearing retainer with 2 threaded holes to attach the release bearing. If you use an R154 front bearing retainer on an AR5, you would need the R154 release bearing option.

All the kits include a bleeder hose, and a full length clutch hose (with a 2-step pressure sensor port) to connect directly to your master cylinder.
Also includes shims to adjust clearance. Please call or text 909-753-7385 10am-6pm Mon-Fri if you have any questions about the installation or setup.

*The R154 kit has a round spacer with a tube that goes into the back of the release bearing, with a pin and a bracket (At the 2 O'Clock bolt position on the front bearing retainer) that keeps the bearing housing from rotating. The spacers go on the round spacer tube, behind the release bearing billet housing.

*The AR5 kit has 2 stackable round spacers because there are a few different bell housing lengths, and two pair of different length bolts depending on if your installation needs 1 or 2 spacers.

*The V160 kit has a wide round spacer that goes behind the release bearing, and 4 bolts to attach it to the front of the transmission.

Install tips:
*Pressure Plate Bolts are 20ft/lbs.
*Flywheel Bolts are 75ft/lbs with Red Loctite.
*Use only DOT 3/4 brake fluid! Do NOT use any brake fluid with silicone in it, it will ruin the seals in the bearing.
(We like the Prestone DOT 3 Synthetic fluid you can buy at most auto parts stores for under $10 in a yellow bottle)
*Completely flush out the master cylinder before connecting the new hose and slave, or replace it with a new one. You don't want old dirty fluid to get pumped into your new release bearing.
*Our release bearing works great with normal 5/8" stock bore master cylinders, or a 0.700" Wilwood master can also be used.
* The supplied bracket goes at the top right bolt for the transmission's front bearing retainer at about the 2 o-clock position. (looking from the front), the slot in the bracket keeps the pin on the back of the release bearing housing from rotating.
* The highest fitting on the installed bearing housing (12 o-clock) should be the bleeder hose. We recommend to sleeve the braided lines with 1/4" silicone hose with a slit cut in it, and zip tie the hoses to each other, then zip tie them to the bell housing coming out the original hole for the stock slave cylinder.
* To measure the bearing clearance first put a straight edge across the bell housing on the engine and measure from the back of the bell housing to the released bearing spring where it will touch the release bearing. Then put the bell housing on the transmission and measure from the front of the bell housing to the face of the release bearing. Subtract one measurement from the other to find your clearance.
* The gap between the bearing and the clutch spring fingers should be about 0.165" +/- .015", this measurement is BEFORE bleeding the clutch, with the bearing pushed all the way in. The shims go on the tube of the black round spacer behind the aluminum bearing housing. Do NOT pull the front of the bearing apart and put shims inside where the fluid seal and o-ring is, that will ruin this unit! After bleeding the clutch you will not see a gap anymore, that is normal.
*You MUST adjust your clutch pedal freeplay after installing the clutch and bleeding it. It should engage the clutch in about the middle of the pedal travel where it feels comfortable to drive. *The clutch should NOT engage high up in the pedal travel, and it should not engage just barely off the floor.
*You will hear some noise from the floater and discs when the pedal is depressed, this is normal for a twin disc clutch.
*If you aren't sure about anything relating to installation or bleeding, PLEASE CALL US. We are here to help! 909-949-0459 10AM-5PM MON-FRI
