How to Properly Torque the Cam Sprocket

I have a 2000 XJ with the auto.

How do I keep the crank and cam sprockets in place to torque the cam timing gear to spec? I have an auto and even in 1st gear the crank just spins freely. When you're putting those sprockets on you don't have a harmonic balancer to use to lock it down to the sway bar with a coat hanger. How does anyone ever torque these things down?

I've always just hit it with an impact gun but I want to try to do it right this go around. I impact gun'ed the crank bolt as well since I had the engine on the stand at the time but I found it wasn't hard to get that bolt to come off, so proper torque needs applied.

You can buy a socket that is desinged to slip onto the end of a crankshaft like a harmonic balancer does. second way would be to wedge something between the flexplate teeth and the bell housing to stop the flexplate from rotating.

Sounds dangerous. I already am missing half a tooth back there.

Wait... I should be able to put the balancer on the end of the snout and coat hanger that to the sway bar. That just might work. I guess waiting to reassemble the timing sprockets always needs to wait until the engine is reinstalled.

Re: How to Properly Torque the Cam Sprocket

recomend two people for the flexplate trick, they acutually make a tool desigend for holding the flexplate. i would recomend either installing the balancher and doing it that way or buying a crankshaft socket and using it.

something like this, allthough is is listed for a chevy. ( https://www.amazon.com/Proform-66901...ft+socket+jeep )

This is the flexplate tool. (https://www.amazon.com/Lisle-23800-F...lywheel+turner)

Re: How to Properly Torque the Cam Sprocket

Thanks for the informations. Can that flywheel turner be used through the flywheel cover plate or does the transmission need removed?

It would need removed. That's why you would use a screwdriver in the teeth through the starter hole.

This is my 2k. Use something as a "spanner" to hold the cam gear and "offset" torque the bolts(torque against the rotation, leverage is your friend).
There are several "webs" that you could grab on to with a ratchet hanlde.

Re: How to Properly Torque the Cam Sprocket

What timing set is that? I have a cloyles. That crank sprocket has a lot of options for you to choose from.

I ended up using the harmonic balancer with a coat hanger to the sway bar.

One day I'm going to have to pull the transmission and torque those engine to flywheel bolts properly. I just hit it with an impact gun several times like I did last time.
