REPLACES TOYOTA # 31230-60230 used in with the Toyota 1GR-FE 4.0L w/ 6 speed manual Transmission.
The design of the throw out bearing assembly used on Toyota trucks can cause uneven wear on the aluminum shaft that the throw out bearing rides back and forth on. The release fork can cause side loading of the bearing as it rides back and forth on the shaft and that can cause uneven wear. When this occurs the throw out bearing becomes loose and can rock back and forth, bind and can cause excessive noise. This sleeve repair kit consists of a precision machined 303 grade stainless steel sleeve that is pressed onto the stock aluminum shaft and is anchored with the included set screws. A new bearing that has been modified to fit over the sleeve is included. Special water proof grease is provided to ensure smooth operation of the new bearing on the stainless sleeve.
DOES YOUR CLUTCH JERK OR CHATTER?
DOES YOUR PEDAL FEEL ROUGH OR NOTCHY?
DOES YOUR PEDAL FEEL LIKE IT’S STICKING?
ARE YOU HAVING TO REPLACE YOUR CLUTCH & / OR RELEASE
BEARING MORE OFTEN THAN YOU SHOULD?
These are the most common symptoms associated with a damaged or grooved quill on a transmission. It is also referred to as the snout, bearing carrier, or case extension. In most cases, it is an integral part of the transmission case & cannot be replaced. The logical solution is to replace the case or the transmission. Both options are expensive & time-consuming, neither of which solves the problem permanently.
In the operation of the clutch, the release or throw-out bearing slides on the clutch snout or quill, allowing you to engage and disengage the clutch mechanism. Due to various reasons, the quill becomes grooved over time. If the quill were made of a harder metal than aluminum, this would not be as common. The most common causes are improper clutch adjustment, defective clutch assemblies, stop & go traffic, keeping your foot on the clutch (commonly referred to as riding the clutch), loss of lubricant, heat, & etc.
The effects of these grooves on the clutch operation are catastrophic. They cause premature clutch disc wear, premature bearing failure (further adding to the problem), sticky &/or jerky pedal travel, rattling clutch forks, transmission damage, etc.
The Transmission Sleeve Kit (TSK) solves this problem by utilizing a sleeve, precision machined out of 303 Stainless steel, which slips over the original quill. This provides a smooth, hard surface for the oversize bearing to slide on. It is anchored with set screws and is removable & reusable. As in the case of the Subaru, it must be removed in order to allow any transmission repairs.
After installing the Transmission Sleeve Kit (TSK) you have eliminated the problem forever! You will notice a smooth, fluid like, feel to the pedal. Your engagements will be smoother. Your clutch will last longer. This, in turn, will reduce the wear on your transmission. It will never groove again!
