Need some advice on an 84 75hp powerhead rebuild, particularly the direct charge pistons.

Service factory manual says to heat up the direct charge pistons with a torch lamp to 190.F to remove and install piston pin.

This does not sound like a lot of fun and how do you keep the needle bearing grease from melting out when reassembling? Any suggestions on how to best do this?

Much thanks.
