In the progress of rebuilding an engine for my truck and the crank gear had a couple chipped teeth i got it removed but isnthere a process to install a different one or what is the best way to install it
lb7 crank gear
- Thread starter 02ilduramax
- Start date
Heat up the gear in the oven and then use a welding glove and it should slide right on to the crank

As long as you get it clean it will be fine in the oven, but you could use a grill if you feel safer that way. Start with 300 for 30 minutes

ive had mine at 500* to get the damn thing off and it still came off with a SHIT ton of force.
if it drops on at 200*, i would be surprised. i would bet it still needs to be pressed on at that point.

Thats why I said start at 200* but you are right it may need a lot more but it is best to use as low as will work.
Most of the ones I've done always required much more heat to remove then install. I think it is because trying to heat it also adds heat to the shaft too plus any galling or otherwise will make it worse.
I've had to do some where I put the shaft in the freezer and bearing, gear etc in the oven. Drops right on at between 200 to 300 degrees with a negative 10* shaft

oh im sure but i wouldnt fret over the temp at 400* when my whole gear was at 500* and i know of plenty of others who have done the same.
probably not the best way to go about it by far but so far ive only lost cam teeth from a mis matched water pump gear pattern. cranks been good and that gear has been pulled twice!
thank you for the info the old one we used a torch and gear puller but it was already junk was trying to stray away from the torch for installation looks like ill be trying the oven
found a thread on here saying someone took a newer crank and reluctor wheel 58 tooth and cut one off so that its a 57 like the lb7s anyone else done this?
