Suggestion: shift the engine
forward, bolt a set of adjustable plates between the shaft and the engine
, flame on!
Picture two plates, possibly 1/2" thick, joined by large bolts with nuts betwee the plates. adjust the angle between plates by extending or retracting the nuts.
Fire blankets over everything else including anything overhead!
On second thought, make the plate that bolts to the shaft flange smaller to reduce its proclivity to heat -sink. The airspace between the plates will reduce heat transfer to the bearings.
Glad to hear you've recovered!
