LB engine cam gear on crank
Need some advice. Is it possible to pull the crank cam gear with the crank in the engine? I have the pan and front cover off, but there's very little space around the gear to get a puller on it. Any ideas?

Re: LB engine cam gear on crank
Why change the crank gear?? It's not necessary when changing the cam gear, unless something is definitely wrong with it (Broken teeth excessive ware)

I think it will be OK, but I'd like to change it if it can be done without pulling the crank. Al |

Whoa, fiber gears are not good! Those gears made within the last 20 years seem to strip and come apart rapidly. If you have to pull the metal gear, drive some thin chisels behind it to move it out far enough to get a puller on it.

If it's a bolt on gear, it will come right off.
Easy job. Replace with an aluminum gear Oops, didn't notice the LB part |

Re: LB engine cam gear on crank
KR Wilson made a special puller for the crank mounted cam drive gear and it could be used with the crank in place if I remember correctly.

Re: LB engine cam gear on crank
I have only done one while crank was in the engine. I drilled and tapped 2 holes about 180 degrees apart so I could pull it off with a standard puller.

Re: LB engine cam gear on crank
Thanks for all the input so far. I finally got a photo of the damaged gear. Any opinions on whether to go with it as is or replace it are welcome.

Re: LB engine cam gear on crank
It will probably be ok as it is.....but I would probably replace it for peace of mind. As you already have the pan off, just remove the front main cap and use a puller (or whatever is needed) to pull/drive it off.

Re: LB engine cam gear on crank
You could either change it or take a dremel with a grind stone tip and relieve the sharp edges.

Re: LB engine cam gear on crank
I had an engine on the dyno for brake in and it had a knock I couldn't find. Turned out to be a chipped crank gear. I used a dremmel to smoth out the area and a magnet to collect the CI dust. All my engines had full flow oil filters. Check with the machineshops in your area for a puller.
