High Quality "VITON" Shifter shaft o-ring for the 1981 (430 only) - 1984, 250,430,500cc ENGINES.
Replaces part #'s 29-70-415-05 or 74-04-211-00.
1981-88 SHIFTER SHAFTS ARE INTERCHANGEABLE AND ARE IDENTIFIED BY THE NUMBER OF O-RING GROOVES ON THE SHIFTER SHAFT.
1981-84 STYLE SHIFTER SHAFTS HAVE ONLY 1 O-RING GROOVE NEAR THE END OF THE SHAFT BEFORE THE SPLINES.
MANY 1981- 84 MOTORS WERE UP-DATED BY A PREVIOUS OWNER WITH A LATE STYLE 2 O-RING SHIFTER SHAFT.
SOME 1984 MOTORS HAVE BEEN OBSERVED TO HAVE EITHER A SINGLE GROOVE OR DOUBLE (2) O-RING GROOVES STYLE SHIFTER SHAFT BUT THE 1984 1/2 FACTORY PARTS MANUAL SHOWS A DOUBLE GROOVE SHIFTER SHAFT. YOU MUST VISUALLY CHECK TO VERIFY.
THE LATER, 1984 1/2 - 1988 DOUBLE GROOVED SHIFTER SHAFTS ARE AN IMPROVED DESIGN AND EASILY SWAPPED OUT. THIS HELPS MITIGATE/STOP THE ANNOYING OIL LEAK/DRIP EVERY HUSKY OWNER HAS EXPERIENCED.
THE 1981-84 SINGLE O-RING IS NOT THE SAME SIZE AS THE 1984.5 - 88 O-RINGS AND DO NOT INTERCHANGE.
EBAY IS A GOOD TO SOURCE TO FIND THE 2 GROOVE SHIFTER SHAFTS, JUST VISUALLY VERIFY.
YOUR ENGINE RE-BUILD IS NOT COMPLETE UNTIL YOU REPLACE THIS OFTEN OVER-LOOKED O-RING, IT IS THE NUMBER 1 SOURCE OF AN OIL LEAK.
