Bearing puller
Don't know if it'll work, but a sliding-hammer puller may be worth a try. Snap-On Tools make them, and presumably the other automotive tool mfg's also have them too. It's just a piece of steel shafting with a 2-3 lb weight (the sliding hammer) that's drilled to slide along the shaft. One end of the shaft has a forged hook attached & the other end has a nut or stop welded on for the hammer to impact against. You could make one fairly easily. The hooked end would be inserted thru the cutlass bearing untill the hook can catch the inner part of the bearing shell & then the hammer is repeatedly slid up the shaft, striking the stop. The hook would have to be as wide as possible, to spread the impact & avoid tearing or cutting the bearing shell. Not as good as a threaded rod type puller but when access is limited by having cutlass bearings on either end of the shaft tube I can't think of a better solution. Once one of the bearings is removed, you could then use a threaded rod & a couple of heavy flat washers that are slightly smaller OD than the bearing shell to pull the second bearing. I'd try the hammer puller on the outer bearing first as you'll presumably have more room to work.
