Valve Timing Gear Installation
How do you install the timing gear on the drive shaft? I'm going to borrow a gear puller to get the old one off but need to get the new one on. I have an installer for the damper and suppose that I could use a stack of washers and the same technique, but there must be a better way.
Also, while I'm at it, the new top sprocket of the timing set has a Torrington bearing. Does this install between the block and the gear? Although I haven't looked closely at it, it wasn't obvious to me how it would be held in place either. Suggestions?

I used to find a socket that will fit over the crank snout & tap the gear on that way.
But I have since learned a better way. Toss the crank gear in the oven for a few minutes at 200*.- 250* . The gear will expand ever so slightly while it is hot & should slide right on the crank by hand. When it cools back down it will contract back to its origional size giving a tight fit on the shaft.
We use this method at work for installing bearings, sleeves, couplings etc. it really works.

Finally figured this out after searching, reading, the heating tip and trial and error.
Next question. How far on should it go, all the way to the shoulder of the crank? Seems like that would be very far in. Right now, it is just past flush with the rear key.
I don't have the cam yet to see how it all lines up.
