Need a special puller to get one out of a 300-6 crank or is there another method?
thanks

 

There is a special puller just for that purpose. Check around ,you might be able to rent one.

 

Second hanky’s suggestion.

Some of the parts vendors lend out pullers and specialty tools...

Another cheap/easy way is to take a 5/16-3/8 carriage bolt and grind a portion of the cap/shoulder off (elliptical shape ) so it just inserts into and behind the bearing. Then, take a wedge (screw driver, small chisel etc) and drive it along side the carriage bolt threaded area wedging it in tight and against the bearing.
Take a loop of decent size and length of chain and attach both chain ends onto the threaded end of the carriage bolt. Next, take pry bar, pipe, even a sledge hammer and string it through the chain loop. Use the heavy weight obeject as a slide hammer against the chain in a banging motion. Generally they’ll pop right out.

Pilot bushings,, can be hydraulically pushed off using a simple grease gun fitted tight into the pilot shaft hole...
