stubborn FSA crank removal

I'm trying to pull apart my FSA Gossamer crank from an Ultegra BB so I can regrease and reinstall everything. But the crank seems pretty well stuck in there. I can't pull the drive side free with my hands. Before I start persuading it with a large hammer from the non-drive side, I thought I'd check with the pros here.

Liquid Wrench, maybe? Or is there some puller tool I should have?

Thanks in advance,

Moammar

crank puller-just get one... If it is a cartridge bearing type crank at least (BB has the spindle that you can't remove). If it is an external bearing system, then it should be loose enough, but i am not very familiar with those systems.

A quick google search seems to indicate that the FSA Gossamer appears to be an external bearing system, so there's no need to guess about what type of crank it is.

Yeah, this is external bearings. Installing, it just slides right through -- tight, but with grease and a modicum of pressure the shaft goes through the BB's tunnel.

I have a puller for square-taper cranks, but this is a newish set-up.

Just give the axle a tap from the non-drive side with a rubber hammer, piece of 2x4 wood, or something else that you can put a little energy into without damaging the metal. One moderate tap and it should start to slide easily.

As Chris W says you just need to use a persuader on the left side of the spindle to get it started. Obviously twisting as you would a seatpost won't help because it's on bearings, so just give it a nudge using some scrap wood to soften the blow.

My rubber mallet just sort of boings off, so I'll give it a shot with a wood drift and a regular hammer.

Thanks, all.
