Dropped set screw into IMS bearing flange hole

[gonzojive]

Progress report
- I was able to slip a zip tie into the exact area where the set screw is. A coat hanger is either too large in diameter or too rigid (I think the former).

- I confirmed the screw is in that area by moving it around with a magnet outside the case and taking a video from inside. I tried this before but visibility was poor - vacuuming up most of the oil helped. Note in plain sight in the video is the IMS-crankshaft chain/sprocket. The screw is on the other side of it - I'm wiggling it around through the case with a magnet, and you can see the oil slosh around as a result.



- I tried moving the screw to the area that is visible by the camera, but it doesn't seem to go over there. Hypothesis is there isn't enough clearance beneath the IMS-crankshaft chain.

- Thus I have begun a project of trying to create enough clearance to move the screw to the area accessible by tools (seen in camera). First attempt was to tighten down the IMS-crankshaft tensioner and hope this would lift the IMS enough to scoot screw under. Tried once and failed.

- Another idea is to move the IMS up by sticking a pole into the hollow shaft and lifting up the pole. I've heard it's not to difficult to maneuver the IMS around like this. At present my LN engineering bearing is installed, including the center stud, making it impossible to fit a pole inside. I don't want to mess up the bearing by knocking out the support stud. Bad idea to knock the stud back into the IMS shaft and later reattach it to an already installed bearing? Other ideas of prying the IMS up?

Thanks to all.

Been following your progress with interest. I have always prided myself with having good problem solving skills and this one keeps me engaged. Not having in person first hand knowledge of the problem site makes it even more of a challenge.
First, I would like to know if you can rotate the chain and sprocket?
If that is possible, this is what I had in mind.
Get some of those small rare earth magnets and stick them on the chain in between the sprocket teeth. Rotate the chain and sprocket to where the set screw is and see if they can attract it and stick to the magnets. If they do, you can rotate the chain back and grab the set screw. Not much chance of losing the magnets, as they stick like crazy to anything ferrous. Just make sure to count how many magnets you use and account for them afterwards. The ones in the picture are from Harbor 'Fright'.

* Opps, I see that you have already thought of this upon reading earlier posts.*
