HP Laserjet 5MP manual feed problem

I have an HP Laserjet 5MP. Essentially problem free since I purchased it. Over the past month or so, the manual feed started being intermittent and finally doesn't pickup anything.

I read the other posts about removing the toner cartridge and the small black strip up against the front edge of the housing and checking for bits of paper, etc. Nothing there other than a tiny bit of dust and that was vacuumed out. Feed from the paper tray is fine.

I replaced the fuser recently but this problem pre-dated the replacement.

Thanks for taking the time to read this. I'm just looking to rule out the simple stuff before I start buying parts.

Cracked clutch on the manual feed assy. Good luck finding one.

Will HP Part# RG9-1083-000CN (Paper pickup assembly) address this issue?

Paper pickup assembly - Includes pickup roller assembly, guide plate, solenoid, photo sensor (PS5) photo sensor cable, and separation pad

No.
Either RG9-1082 or RG5-2791 will work. It's a little tricky to replace it.
Here's a good deal on one. http://compare.ebay.com
We do have an instructional video showing how to replace it if you can't figure it out on your own.

Okay. Picked up RG5-2791 and installed it. Same problem. Tray feed works fine but manual feed shows no signs of life.

When I first installed the part, the manual feed tray was spring loaded to the up position. As soon as I powered the printer up, it dropped down flat so I'm assuming the solenoid is working. Or least the basic gearing is turning to allow the plate to drop down flat.

I can't see anything wrong with the original part -- no obviously broken/damaged shafts, gears, etc.

Open to ideas.

Took apart the outer white wheel (near the solenoid). The clutch mechanism is intact. No cracks in either the white gear or the grey cam housing with the spring inside it. Pickup wheel turns with slight resistance in both directions. Outer white gear only turns counterclockwise and freewheels for about 3/4 turn in clockwise direction as spring inside the clutch winds tight and then stops it.
