Timing gear removal

The key holding the timing gear to the camshaft needs replacing on my Ford 600. This model has the spring clip rather than the bolt holding the timing gear. Is there a way to
change the key without removing the engine and camshaft? The aftermarket manual I have says I need to remove the camshaft. It appears like the end of the camshaft is larger
than the diameter of the actual shaft so a gear puller won't work. Hope I'm wrong. Thanks for your help. Russ
 
Sorry I didn't answer both of your questions. The tractor is a 57 and the engine is a four cylinder. I believe it is called a Red Tiger engine. The Jubilee and first models had a bolt holding the timing gear on but the later models have a snap ring. The ones with the bolt allows the timing gear to be pulled but it appears like the ones with the snap ring requires the entire engine and camshaft to be pulled. My hope is there is a simpler way.
 
Ok my fault thought was a truck. Just remove snap ring and it will pull rite off with a puller. Putting back on be the fun part. There is a rear on rear that drives hyd pump.
 
Thanks for your response. Have you ever done one with the snap ring? It appears like the end of the camshaft is larger and the gear won't fit over that extra diameter. However, if that is true, I have no idea how they installed the gear in the first place. I tried pulling the gear but it is aluminum and I'm afraid to put any more pressure on it. It looks like the key is sheared and the gear has moved on the shaft but the key is now holding it from coming off. The reason I suspect this is when the timing mark on the flywheel is set right and the distributer rotor is on No. 1, the teeth with the indents on both gears are lined up but valves aren't closed. The crankshaft gear appears to be correct but the camshaft isn't in sync with everything else. I can see the indent for the key on the timing gear but can't see it on the camshaft. The tractor won't run when it is timed correctly but will run poorly if I advance the distributer about 30 degrees I had a good mechanic look at it and he also agreed that the timing gear must have moved on the camshaft. The valves should be closed for firing. Do you have any other thoughts on this. I replaced the distributer and coil and gave good spark. Thanks for your help. Russ

Why does it have a snap ring if the gear can't come off?
