For 1972 85 thru 125 HP models

CONE - WRIST PIN
PART NO. 319924

For 1972 85 thru 125 HP models

Use these two tools as a set. Since 1972 the V-4s have used a new type retaining ring to secure the wrist pin in the piston. The wrist pin cone acts as a guide and a compressor for the ring while the wrist pin driver seats the ring in the piston groove with an easy push of the hand. Using these tools prevents excessive ring distortion. Tools 317829 and 319924 are also used on snowmobiles.
