I've tried to find this in other posts but no luck. The engine is a 1971 250 with a Delta 260 cam which I'm replacing with a stock grind for friendlier street driving. The engine has 2500-3000 miles and is in the 1951 Chevy truck ready for the cam and crank gear to be removed.

What is the proper way to remove the aluminum cam gear so it can be reused on the new cam.

If the alumn cam gear cannot be reused how can the crank gear be removed since it is not tapped for a puller and there is no clearance behind the gear for a puller.

No doubt I'm overlooking the obvious but I'd rather ask now than explain later.

The cam gear can be pulled off. A press is the best way.

I will say this,the gear really should not be reused.

If using a press, use a propane torch to heat it up, it will swell in size and may not remove any metal when pulling it off. To put it back on, heat in oven to 475 for 5 minutes, have the cam ready and a soft deadblow hammer. Have all parts ready and reinstall, use the hammer as needed.

The crank gear will need 2 holes drilled in it and tapped for 3/8 bolts, than a puller can be used. Stuff the front area and oil pan opening with rags to keep debris out.

I like to drill all my crank gears before install for this reason. Tom

Tom,
Thanks for the quick reply. I was thinking along the same lines but wanted an experienced opinion. Looks like I'll be drilling and tapping in the morning.

Would the crank gear benefit from heating in the oven before installation?

The crank gear does not need heated. Tom
