What do you mean by the drift? Im assuming crankshaft. I know how to get the bolts off but feel a bit off about prying the wheel off with force even tho I would have to be replacing the part I would be worrying most about damaging.
Sorry, regards drift, that means perhaps just my terminology.
A drift is just something with which to apply a directed force. So one "drifts" a pin out of a bore etc. right? Anyway in our context, i.e. something to transfer a brief impact to the crankend, would be merely a M8 bolt, or a centerpunch, or for me on my 044 chainsaw I'd got a stout iron rod say 6" long, 1/2" wide, tapering down to about an 1/8.
Look see this bloke here, what he's holding in his left, in his right he's got a hammer, yeah?
well for your ts400 crank lose off the crank nut by about 2-4 turns (i.e. there's a gap under it for the wheel to pop off out to), and then
you hold that drift I mentioned above, IDK just use a big blunt punch, right hard against the crankend. Have someone pry under the wheel - they won't break it if they ain't stupid. Get them to pry enough to feel the pry just flex under elastic load, then YOU give the other end of the punch/drift a sudden whack with a hammer directed parallel to the crank axis.
You are using inertia to break the wheel loose from the shaft....it's always worked for me, but do have a think about it first. There's almost certainly a youtube vid outthere to help.
