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 dis-engage 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, precission 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 & re-usable. As in the case of the Subaru, it must be removed in order to allow any transmission repairs.
After installing the Tranmission 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!
The kit comes complete with a 303 Stainless steel sleeve, set screws & hex wrench, oversized release bearing, hi-temp grease packet, notification sticker, & instructions. The kit comes with a 1 year, unlimited mileage, warranty
