^^^ what he said, but more so. It's a road crank. You need 5mm more spindle length to get it out to MTB-triple chain line to match your MTB-standard crank and derailleur and frame.
It might also not be compatible with indexing, if you are doing indexing. Some old style replica cranks have their rings spaced much closer together than a standard MTB triple. If you have the barcons with ratchets it's going to be ok, if you have the flat bar version with a trigger shifter you may have trouble. That would also require you to bring in the limit screws.
That just covers the chain line. You might need some luck with the crank clearance too. The touring bike came with a MTB crank for a reason, you need the width to have clearance within the chain stays for big tires and their fenders.
