The crank on my '24 Touring is bent in.
Maybe that's why a previous owner added the bumper (after running into something)?

Easy or difficult to remove and fix?

Is the crank really bent, or just sagging due to a worn out bushing (the bushing is pressed into the front of the engine pan)?

If the bushing is good, turn the crank vertical and check by eye whether it's the crank that's bent, or the front of the pan (that holds the crank bushing) that is bent down.

If it is indeed the crank that is bent, you can remove the ratchet on the back of the crank, then slide the crank out and straighten it on the bench.

If the front of the pan is bent down, you could try removing the crank, then sliding a long pipe or rod into the crank bushing and pry up to bend the end of the pan back up.

If you decide to replace the bushing, here is a review of the procedure:

The bushing in the engine pan may be really worn. If it's worn a lot the crank will sag. Remove the crank by removing the small pin that goes through the crank ratchet and the crank. The crank could be bent but going by the droop and worn hole in the radiator apron the bushing is really worn. Probably a little of both.

If you can fit the crank back through the bushing and crank the engine, then you only have a bushing issue. If the crank won't fit or jams it is possible the crank is bent and the cross member is bent. My 1915 crank was bent along with the cross member. I used a long pipe in the bushing hole with a hydraulic jack on the end and bent the assembly back in to place, it took about 3 or 4 days to complete
