I have not had this problem but I think if you drilled and tapped the sprocket
say about 2 1/2" radius 180 deg apart using 5/16" NF thread. Then find a piece
of flat iron 1/2" X 1 1/2" X 6" and drill 2 holes in the flat iron to line up
with the 2 in the sprocket. Insert 2 5/16" NF bolts about 3" long through the
flat iron and thread them into the sprocket. You should be able to tighten the
bolts with the flat iron against the end of the crank shaft and pull the
sprocket off. A rap with a hammer may also help while it is under stress.
Failing this you may have to use heat.
Good luck!

Subject: Timing sprocket removal
I am trying to change the timing chain out on my '67 Sprite. Engine is out of
the car and on engine stand. The larger camshaft sprocket moves fine on the
shaft, but the crankshaft sprocket refuses to budge. Clearance behind the
sprocket is not enough to get a gear puller behind it. After prying with
screwdrivers and crow bars to no avail, I finally cut the timing chain with a
cut-off tool th gain more access to the sprocket and removed the camshaft
sprocket, but the crank sprocket is still frozen tight. Still cannot get the
gear puller behind it. I have pried and pulled and tapped but it still is
sitting there smiling at me. I havenet tried heat yet, not knowing whether I
should heat up the end of the crankshaft. I do not have actelyne, only
propane.
Anybody have any good ideas?
