Well now, J40 shows how brilliant she is by reading the
problem incorrectly, again...
The job, in itself, is not difficult, with the right tools, anything
can be done. The real question is if you have the experience to
do the job as an "inframe", or need to take the engine out, inframe
may be a little more complicated, but it will be easier...

Canzus, crankshafts can be turned inside the frame. but i can assure you that a ring gear that came with flywheels due to have tack welds and take weld points take welded and layded on a flat service, it is only the flywheel withought the flywheel without the ring gear that bolts to a rear cranckshaft flywheel that can bolted to the bolts on the back of the flywheel, and ring gears have no bolts holding them on, the user stated they needed to change the flywheel ring gear, this method is best done ot of vehicle...Lets not be negative on proper procedure...have a nice day....Janet

If the bolt holes are not too badly messed up it might be possible to go a size bigger or a threaded insert, without removing the engine. If unable to "rebuild" the bolt holes it would be best to remove the engine to replace the crank.

Flywheels don't have welded ring gears, flex plates
do have welded ring gears, do you know the difference??

No harm is done by learning ones talents, i have many hobbies i adore. A Ring gear tack welded to a flywheel would break before harming the machine bolts that hold on the flywheel to the back of the flywheel..On plug wires if a little room is allowed, it only gives one tme to arrange a good fit.Janet

However, when a bolt that holds the flywheel to the crankshaft is
either over tightened, or under tightened, there is a very good
possibility that it will loosen, and knacker the threads in the
crankshaft and also knacker the holes in the flywheel as well,
but of course, you knew that, but decided to keep it a secret
from us all, didn't you???

This is what happened....
The fly wheel bolts came loose and ground down the crankshaft and made the holes egg shaped, so all I want to know is, How do you take out the crankshaft while the engine is in the truck still or would it be easier to take out the engine? And how do you take out the Crankshaft?

It depends on how well you can torque the main caps while
laying on your back...
Inframe- Pull the tranny, the bell housing, the clutch cover, flywheel,
then put the bell housing back on. Drain the oil, disconnect the oil pump
pickup tube, pull the oil pan, check the rod caps for numbers, no numbers,
go to your FLAPs and purchase a set of number stamps, stamp numbers
on the rods and caps, pull the rod caps, pull the balancer and front cover,
stamp the main caps with number stamps, pull the main caps. Crank should
fall on the ground...
Installation is reverse of removal...
