Reepicheep,
Thanks for the excellent pic of a bad gear. I will look closer at my old one when I get home. |

just went on a ride to get some lunch... a little flicker but nothing to worry about but when I stopped let it idle the light came on full and stayed until I pulled the seat and popped the fill plug under a lot of pressure? still trying to figure out why... |

pulled the cam cover over lunch, it's kinda nice working in a place where we got tools, plus I can take a full hour. Wow those things are sharp, looks like I'll have another project to do this weekend or next, anyone know how easy/hard this might be? Looks like I'll need a gear puller any other advice/tricks. BTW my new cams look like they haven't even been used. My old number 4 looked to have a hardening/plating-if they do it, problem. |

sound slikie an oil line obstruction.....
why did you pull your cam cover?!??!?!
internet-borne paranoia strikes again.
(if it were your oil pump drive, you'd have too little pressure, not too much.) |

If you already have the cam cover off, it's easy. Just pull the oil pump out (probably optional) and remove a nut. The gear is just sitting there with a little square key.
Tramp, I am glad your tuber has done well with so little intervention. I would encourage you to do a search here and see how many tuber owners here have experienced a failure of that gear, and what the ramifications to the bike were, and compare that with the 20 minute preventative check that can determine if a particular bike is at risk or not.
I also wonder if it was not what finally killed Dyna's engine. |

Pulled it because I had checked the gear earlier this summer and knew that it was showing wear, I didn't believe that it would cause a problem so I was going to get back to it this winter and fix it. Say what you want about paranoia, but when my oil light flickers for three days, and then stays lit I tend to think there's a problem and instead of re-rebuilding my engine I'm gonna take the twenty minutes it took to pull my exhaust and cam cover and take a look and well, call me a hypochondriac, paranoid, whatever, they look like knives on two sides, I don't think that this is the cause of the overpressure problem, but it definitely needs taken care of. Mine may have been caused because I made up a stainless tubing peice that went from the oil pump to the oil filter houseing thus causeing it to have a misalignment issue but still it aint good, don't seem to have a flow problem which is strange but my bag was filling up more than it should when I pull the pump I will check for blockage, but as I said this was a much easier check and fix than the alternative. |

On the other matter all I can say is good for you Tramp! |

ceejay- mot only does it sound, still, like a blockage issue, but it seems you've 'fabricated' an oil line for your machine, as well, and you've 'checked' your gear.
in the same sentence you mention that you 'don't seem to have a flow problem', but your ' bag is filling up more than it should'.
no offense, buddy, but back where I come from, that's what we call:
"A Flow Problem"
It indicates stricture somewhere on an outlet line
from the oil tank.
but, please- continue your inspection of your oil pump drive gear...
One night in SoHo I met a guy who'd lost his keys, and he was looking around under a streetlight.
I offered to help him, and I asked whereabout he thought he'd lost them. He told me he lost them at the other end of the Block.
I asked, incredulously, why he wasn't searching for them there.
"The light's better on this end", he replied.
I believe they were attached to an oil pump drive gear.... |

fair enough, in order for me to find a blockage of flow I have to pull my oil pump anyhow, which is a two hour job-at least, my oil pump drive gear which I know was having issues was a 20 min job to look at. Now knowing that my drive gear which I checked earlier in the year-remember, was going it seemed to me that is the first place to start since that could kill two birds with one stone and is much quicker. While I don't lose my keys very often, when I do I often bring a flashlight. |

Reepicheep,
Thanks again for more great pics. My old gear is clearly not grenaded like your example. I'm leaving for home in a minute but my memory is that it is not as sharp as the new (I presume) gear you show. Kind of a moot point because I will be replacing it. After toasting my engine I am paranoid <G>.
Ceejay,
I would definitely check for a blockage. I was surprised by the debris buildup at the pressure sensor. I was actually checking the check valve when I noticed that I couldn't see through the hole with the sensor removed. I wish I had been smart enough to put a clean white cloth behind it before I blew it out with compressed air. In any event, it shouldn't have been there as I understand that is right after the oil filter.
At this point, I am paranoid. I am going to check every passage and when I put her back together, I am going to be very anal about cleanliness.
Paranoia, the destroyer. |

Perhaps if he shot out the streetlight, and went and sat in his car, the keys would somehow then have never been lost in the first place 
For the record, I do not recommend people pulling their cam covers willy nilly. Nor do I recommend people with low milage or no suggestions of problems dropping their oil pump with every oil change.
I do think it is worth spending 20 minutes dropping the oil pump on a tube framer after 15k or so miles (maybe 10k if you spend a lot of time bouncing off the rev limiter) and inspecting the gear for wear. Do it every time you replace your battery

Okay, I pulled out my reading glasses and took a better look at the old gear. (Dagnab, old age.) It is definitely worn. Actually, now that I know what to look for, it is pretty easy to see. A few of the teeth are nicked on the end, so something must have been moving sporadically. In addition, a few of the teeth are "gouged" as shown on your first pic. Thanks again. This is my first time this deep into the engine and it really helps to see some examples.
Ceejay,
Good luck with finding your problem. Your symptoms are very similar to mine. |

My guess is you didnt see the pictures or hear the story
Remind me to tell you some time...
