Chunked a bearing on the main shaft and I see the bearing housing is cracked
Is there a trick to removing these pulleys?

Ive got a L3 that looks just like that and ive had that pulley off to put bearings on the main shaft. I didnt have any problem getting it off. If you decide to use heat id be very careful with it. I dont know how much heat the laminations in that header clutch coil will stand
Good luck

My assumption is after removing three bolts off the main pulley, it would just pop loose. The 3 jaw puller has a lot tension at the moment. Figured I could heat near the center if that's all it takes then tackle the clutch. I know a guy near Preston, may have bearing housing

Screw the 5/16s bolts that you took out into the other holes and it will push off quite easily. Blow the holes out first, plenty of lube, and alternate the tension.

Lynn has your answer. My F2 is like that. Once you figure it out it's a breeze. Probably in the service manual which nobody has....
The engineers were thinking. When i do a mainshaft brg, I do both sides. That other one has as many hrs on it. When I got my 4000hr R62 I wish i'd sent it to the shop for PM and had new main brgs installed. A couple years in it ate the rt side and of course spun on shaft and ruined it. Would have been half price or less. Think that shaft was around $3500.
