Cover, Rbc Plastic With Cap
Part #195422GS
This rear bearing cover is designed to protect and insulate the rear bearing of the engine. It is an authentic OEM replacement part with a diameter of approximately 8 inches. It comes with a center/dust cap for easy access to the bearing. The cover acts as a barrier that prevents dirt and other contaminants from entering the bearing and potentially damaging it. It also protects the bearing from harsh environmental conditions and keeps it adequately lubricated. Over time, the cover may crack or break, leaving the bearing exposed. A faulty cover will result in several issues such as excessive noise and vibration, increased friction and wear, overheating, and lower overall equipment efficiency. To complete this repair, pry the center cap off first and then detach the old cover from the rear bearing. Clean the mating surface, align the new cover with the bearing, and snap the center cap into position.

Put some dish soap on the rubber, push into the tank hole, slip 1x2 into the handle of the tank and over the new part and pry down pushing it into the hole. Took about 2 minutes.

old valve dripped gas when opened on cold sub zero day
4 of 7 people found this instruction helpful.
  • Alan from RADFORD, VA
  • A Bit Difficult
  • 1- 2 hours
  • Pliers, Screw drivers
old valve easily pulled out with screwdriver and pliers

install difficult due to 40 degree cold temp and bushing didn't want to squeeze into fuel tank hole

install required lots of liquid soap on bushing, which popped into place by using upward prying pressure from 3"X24" plywood braced into under-shelf of gas tank
