Location: WHEELING,WV.>>>HOME OF WWVA | i just removed one using a pointed punch , down the side a few times , between the bearing and crank . kinda chipped away at it , til i could remove the bigger of the
pieces . i always thought they were bronze , not this one , it was made of something that is magnetic and bronze aint supposed to be . i'll be replacing it with what some
call an adapter bearing . its a roller bearing the fits the bigger of the registry holes , part number #FC69907 . i messed with the trans. for over 2 hr's trying everything
possible to put the input shaft into the old bearing just wouldn't go . it would fit with just the bellhousing in place but not with everything inline . so i looked real good
at the bearing while it was still installed . it did have some rough edges even before i tried the trans but i thought it would go alright but not . ---------------------------later |

Location: New Zealand | I've always used grease to remove the bearing, by loading the hole the bearing sits in with grease and then using a shaft to slide into the bearing that is a snug fit. Striking the end of the shaft creates pressure which pushes the bearing out and no chance of scoring the surface that holds the bearing.

Location: Alaska | I have tried the grease trick before, very messy and didn't work very good. The best way is the little fingers on a slide hammer that grip the inside edge of the bearing. |

Me too, all I get is a face full of grease. I prefer a puller.

Location: WHEELING,WV.>>>HOME OF WWVA | grease works great on the roller bearing pilot . i used grease for the bronze pilot but what happened was i hit an oak so hard it blew grease at the back of my hand . so hard it felt like the dowel
splintered into my hand , i didn't want to look but it was just the force of the splatter . no kiddin i hit it so hard that when i pulled the dowel out of the hole , there was smoke . it might sound
like i'm kiddin but not so . i doubt the puller would have worked as the bearing was seated with no edge to grip . chippin away took probably 2 minutes ----------------------------------------later |

Location: Mandurah, Western Australia | I've had no problems using the grease trick on bronze bushes on 3 or 4 engines, shown to me by my retired mechanic mentor Tony, now sadly deceased. A bit of heat will also help if nothing seems to be happening, saves a lot of effort and less risk of damage. The older I get the more often I remember to wear gloves and eye protection when I'm attacking parts with a hammer .. have had several mashed thumbs and a friend with eye troubles.

Location: cornpatch county, Southwest IOA | So Chuck--You are using the adapter bearing. If you have a crank that is not drilled for a pilot, you use that bearing and cut off about 3/4"from the end of the input shaft? But you won't have to because you are leaving out the pilot bearing???...............................MO |

Location: Newark, Texas (Fort Worth) | Removing a damaged pilot bearing can be a difficult task and may require a special tool. Installing a pilot bearing is typically pretty straightforward; just make sure it is seated properly. If a cutter is used to cut the bearing race or cage, make sure to remove all debris from the hole. Sometimes removal of this bearing may be as easy as packing the center of the bearing with thick grease, then striking a dowel that fits tightly in the center with a mallet or hammer. Removal may require a great deal of patience.

| I have used a slice of bread on bushings. Works like grease with on mess. keep putting it in hole and use a punch or something for a snug fit and tap bread in, continue until it slides right out. |

Location: Williams California | I usually use a small slide hammer with a 2 jaw fixture I bought from the Snap-On truck years ago. Works well on 95% of all pilot bearings and bushings. I have had ones that had gotten so hot from lack of grease, that they were nearly welded into the back of the crank. These I had to carefully snip out with an oxy/acetylene torch, and dress the bore afterwards with emery cloth.

Location: WHEELING,WV.>>>HOME OF WWVA | there was no way mine would have pulled out as there was nothing to grab hold of . using the grease method , i used enough force to make vapor . on the interweb they show tons of the roller bearing
style being hydraulic'd out by several means but not one of the bronze being removed . mine was son tight it was shiney on the crank side . i had thought of using the gas wrench but i din't want to
heat up the crank register . with a good needle pointed punch , it chipped away extremely easy with very minimal damage to the bearing hole . maybe took 2 minutes --------------------------------------later |
