I purchased a new crankshaft timing gear for my 38 216 and want to know the best way to install it.
The shop manual just says to drive it on.
So do I just line it up and hit it with the bfh?
Would it help to heat the gear up first?
What about drilling and taping the crank snout and using a harmonic balancer installer?
Thanks,
Matt

Heatring it woundn't hurt. I would use a leather or dead blow hammer to drive it on.

Yes, some heat will help. It is a pretty tight fit. And of course the trick is to make sure the key way is lined up with the gear when you install it.
You will need a sleeve type driver to get it seated completely. You have to drive it on straight.

. Use a piece of tubing to drive it on to the crank shaft. A 2" diameter nipple about 8" long works well from your plumbing supply shop. Hammering one side and the other is not a good method. .

If the crankshaft is out of the engine I would use a shop press and support the crank behind the front main bearing, if the crank is still in the engine warming the gear and a piece of pipe is about the only method available but dont use heavy blows with the hammer or the crank could fracture. Dont ask how I know this.
