Loctite Bearing Fit is specifically designed for press and shrink fit applications, it requires a total absence of air to achieve max strength. Using it eliminates the risk of the sleeve spinning due to differential expansion as the sleeve warms up in operation. I’ve seen this problem on quite a few gearboxes that then required new shafts. Just not worth the risk of not using it on a crankshaft sleeve where a spinning sleeve will ruin the crankshaft.
