My apologies. It’s the oil pump drive gear.Hello to all,
I’m new to this forum but it seems like it better than the others I’ve been on. But anyway I’ve got a 93 dyna low rider w/ ultima ignition, ev27 cam and fishtail exhaust. I haven’t had it for too long but been wrenching on it ever since.
my question is what would cause the pinion gear to explode? Here’s a little background in the situation. Oil pump wasn’t working so I went in and found that the key way was gone from the pinion gear there was no damage to anything luckily so got any key and fixed it I ran it for a couple times after priming oil pump then on the third time I was going to run her all it would do was spin. No fire, no compression. I checked everything that it might have been on the outside(good). Just opened the cam chest and found pinion gear in 3 pieces sitting in the bottom. But there’s no damage to anything else which is a blessing but wondering what might have caused it. The gear wasn’t in perfect condition by no means but it got chewed up pretty bad. Any feedback is appreciated and welcomed
