Pulling Pilot Bearing
 
hi,

if u dont have a bearing puller, how could you extract a pilot bearing from the end of a crankshaft, without damaging the crankshaft?

I used to fill the hole with grease, stick a wooden dowel in the hole and smack it with a heavy hammer. The grease will push the bearing out.

Ayuh,......

That's My 1st Choice,............

2nd would be Welding a bead around the inside circumference,+ shrinking it out..........

hi,

thanks for all the info. i tried using grease, but it wouldnt work. i think because i had the bearing all distorted from trying to pry it out. i rented a puller, and it came right out!

At work when we need to remove bushings we fill them with clay instead of grease. Not as messy plus you can take the plug of clay and re use it on the next bushing.

I guess the grease method relies on pressue. You must fill the entire area behind the bushing with grease and then stick a dowel or old input shaft in. The pressure forces the bearing out a little. remove the dowel and add more grease and repeat. Uses a lot of grease. i think I might try the clay method next time. Last year, I had my neighbor weld a large screw (it was an old body mount bolt from a 69 camaro) onto a old dent puller. Since the bushings are soft, I threaded the screw into the bushing and a few pulls and it came out. This won't work for a roller bearing though.

hello,

come to think of it. when i was around 19yrs old, i swapped an engine out of my '67 chevy, stick, and put it in a '69 chevy with auto tranny, and had to remove the pilot bushing from the 67' engine. my uncle used a heavy duty tap, screwed it into the brass bushing and clamped visegrips on the square shank of the tap and tapped it out with a hammer...bob
