It is not uncommon on 68RFE transmissions to find the underdrive balance piston snap ring blown off. When this occurs, catastrophic damage can occur to the overdrive clutch drum and underdrive hub assembly, rendering the clutch hub useless.
SunCoast has designed and manufactured a specialty 68RFE Input Clutch Hub Retainer Drill Jig for precise alignment and easy installation to alleviate this issue.
Input Clutch Hub Retainer Drill Jig
Precision-crafted from 6061-T6 billet aluminum, SunCoast's Input Clutch Hub Retainer Drill Jig is a game-changer for the industry. Engineered as the definitive solution for a persistent industry-wide issue, this innovative tool offers a seamless fix for the notorious beveled input clutch hub snap ring failure that plagues transmissions. Its design allows you to effortlessly secure the drill jig onto the inner drum, enabling precise drilling and tapping of the inner drum to affix SunCoast's input clutch hub retainer.
Designed with efficiency in mind, this drill jig not only aids in the snap ring retention process, but also doubles as a convenient tool holder for all essential components included.
OPTIONAL ADD-ON: GET THE FULL SNAP RING RETENTION SOLUTION
In addition to the 68RFE Input Clutch Hub Retainer Drill Jig, SunCoast has designed a Snap Ring Retention Solution package with everything you need to solve your problems. As an optional add-on to the input clutch hub retainer drill jig, you can choose to add the following in one convenient 68RFE solution:
Input Clutch Hub Snap Ring Retainer
Machined from 6061-T6 billet, SunCoast's Input Clutch Hub Retainer follows the patented SunCoast design of encapsulating the snap ring in a recessed pocket, ensuring there is no potential for the snap ring to come out of the groove.
The secure placement of the snap ring is further reinforced by three Torx screws meticulously positioned within counter-drilled pockets, eliminating the necessity for additional machining to clear the Underdrive Piston.
Billet Snap Ring Retainer
SunCoast's 68RFE Snap Ring Retainer is manufactured from 6061-T6 billet aluminum stock. It is made .040" taller than the factory one to increase spring load. By adding additional spring load tension, we prevent expansion and blowing off, causing catastrophic damage. This retainer is also manufactured with anti-rotational tabs to ensure no movement occurs.
This SunCoast Billet 68RFE Snap Ring Retainer must be used in conjunction with the factory snap ring.
M3GA 4C Snap Ring Retainer
The 68RFE 4C Snap Ring is known for blowing out from the center support. This new SunCoast Billet 4C Snap Ring Retainer is a permanent fix. This spring-loaded piece encapsulates the snap ring effectively, preventing this from ever occurring again.
Ring Gear Thrust Washer
It is not uncommon to see the thrust washer that rides on top of the 4C reaction ring gear fatigue and break at times into several pieces. When this failure happens, it leads to catastrophic consequences. The factory unit is also manufactured from plastic making it ineffective under high thrust loads.
SunCoast's solution involves a complete redesign aimed at enhancing reliability and durability to avert future failures.
Crafted from a solid billet of 6061-T6 aluminum, this new SunCoast piece is a testament to durability. Moreover, its engineering incorporates redesigned angled oil slots, ensuring improved fluid feed to the 4C clutches and superior load distribution compared to the factory model. This revamped component stands as an essential addition to any 68RFE transmission rebuild, guaranteeing enhanced performance and longevity.
