Bad Ring Gear, 42 D

I split my 42 D today to check Ring Gear. About a year ago the starter gave me trouble, grinding when trying to start it. The starter gear does have some wear, caused by the bad ring gear I beleive. If I remove the Ring Gear, can I turn the ring gear over and reinstall it using other side?
 
I can't say if you can flip it (sometimes the tooth angle is such that you can't), but I have been known to take it off and rotate about 135 degrees since motors often stop in the same relative position and by moving the bad section to someplace else you could get some more use out of it. Maybe somebody else can chime in about flipping it.
 
Yes I agree with just moving it 180 mark it with a paint marker or something remove it place flywheel in freezer over night then put ring gear in oven bout 325 put flywheel on flat surface set ring gear back on
 
I have flipped hundreds of ring gears. Every thing from lawn mowers to Macks and every thing in between and never had a problem. Just don't heat in only one place with the torch, keep it moving or you will warp the gear.
 
I can add a comment. I have a big 400 that had a problem like that, only way worse. I had to roll the engine every time to find a spot where the starter could find some ring gear teeth. Against some advice here, I stretched the big, flat wound spring to put the pinion deeper into the flywheel. Done that a couple years ago and it starts every time.
Remove the starter and disassemble the nose cone and disassemble the flat wound spring via the shouldered anchor bolts. I recommend you measure the relaxed spring and record that length. Then find a pipe, shaft, screw driver handle, something you can clamp in the vise and set the spring down over it. Take two hefty screwdrivers and insert them horizontally into the flat spring, on opposite sides of the spring. Pry down with both and stretch that coil a bit. Move up a coil and repeat. Keep moving up until you are to the top coil. Look for about 3/8 or 1/2 inch more total length in the spring.
I would have fixed it right but I could not find a ring gear to buy and was afraid to try the "flip" in case the teeth had a bevel in one side. Anyway, this has worked very very well for me.
 
Well, I got the ring gear off this AM and decided to move it 90 degrees instead of turning it over. The the teeth were bad for about 6 to 7 inches on ring gear and 180 across those teeth were also bad so I moved the ring 90 degrees to hopefully get into good teeth. The starter gear was a little buggered so I had it replaced. Have flywheel and clutch back on now I just need to get tractor back together. Thanks for all the coments. Dick
