you've removed the front pulley and the engine cover plus all else involved, The way I see it hardest parts done and the rest should be a breeze. :wink:

It probably does not help much, but I have a neighbor that is waiting for me to get some room in my shop to fix the same problem on his cub.

you are part of the problem!!!

Now for some different news. My last overhaul involved a machine shop oversight in not replacing the oil galley plugs (that's another story). Repair involved removal of the cam gear, installing the galley plug and replacing the cam gear. I do NOT know how they removed it, however, I was there to see how they reinstalled it. They had a little burner set-up that heated the gear to he point that it just dropped on the end of the camshaft. The engine has had no problems since and this one is on my "Hot Rod" that turns 24-2600 RPM. So maybe another approach :?: :?:

Thanks for all the great advice. I took bits and pieces of it it and came up with a solution. First I drilled and taped the old gear used a puller to pull it. I drilled and tapped the end of the cam to 5/16NC. Then started the gear and heated it up, I don't have a good torch so I used a propane with map gas, It didn't get it cherry red but did get hot. I used a bolt and washers and to press the gear back on. The cam shaft sticks out just pass the gear so I used a longer bolt and socket larger than the shaft and finished pressing the gear in place. After installing the oil pan I wish I would have split the engine just to put the 3 bolts in the rear of the pan. Now I have to touch up my bolts and finish installing the front. Next to rebuilt the pump and cross my fingers that it doesn't happen again or GP will be sold as parts!!!

Probably just as well. Cherry red would have probably ruined the heat treating.

When heating objects, I do not do it anymore without my infrared, laser guided hand held thermometer. It's ease of use and fast readout makes it a snap to know the temperature of an object.

the sollution you came up worked ok but there is one problem. by driling and taping the end of the came shaft makes it a weak point. . the cam gear drives the hyd pump. This will be a braking point under a heavy hydraulic load. May last forever, may not.

450* is the max you should heat interference fits up, red hot would be badddddd. i see your logic that the "hotter it get it the more it expands" but it is not so, it will start expanding inward toward the center and actually make the hole SMALLER. you want to put heat to the outside to get the outside to expand and draw the inside hole open with it. i looked in my IH service manual since i last posted and it says to soak the gear in boiling water then slip it on.
