single mass flywheel?
So im about to yank the motor on a 94 to investigate the horrific noise coming from between the motor and tranny.
Its got a 5 speed.
4x4.
All stock.
At idle in neutral there is an ungodly scraping noise..
I will try to take a video and post soonish.
Whats the deal with single mass flywheels?
The trucks owner thinks that is what will cure this problem.
He doesnt complain about any clutch issues or strange vibrations at his feet.
Could this be pilot bearing?
Someone else has suggested that this flywheel may be separating.. maybe?
When i get it torn down and it does turn out to need a flywheel... what part # would you guys recommend?

You don't have to pull the motor. I bet if you pull the clutch inspection cover you'll have some ball bearings in the cover from the DMF. The DMF is a two piece flywheel that dampins the gear rollover noise. Going to SMF will create some gear roll over noise.
The main benefit is you don't have to worry about the DMF flying apart and destroying the trans or block.

^^^^ Also, when you've got the inspection cover off, try to turn the pressure plate a little. If it turns relative to the forward part of the flywheel (part with the ring gear), the DMF is ready to let go.

Either way... oil pan seal, dipstick flange seal, oil cooler, maybe timing cover seal too...
Easier for me to take care of everything at once with motor out.
Any suggestions for replacements.. either single or dual mass...

So valair it will be when it comes time to place orders.
Now...
Plucking the motor..
On my 2000 i had to pull the turbo for clearing the cowl...
Looks like i have more room with this 94...
You guys had good luck going str8 up and out or still better to tear down the nose?
Anything in particular i should keep in mind in regards to orientations, alignment issues, or bracing i should do for the trans?
Used a ratchet strap on my 4r100.
I will need to pick up a clutch alignment tool too unless the one for small block gassers fits.
This will be my first diesel flywheel/clutch job.

Stick a (pun intended) fork in that flywheel; it's done. Speaking of which, when you do the clutch/flywheel, look into a new clutch fork from Ford; IIRC, there's a TSB regarding a new improved version.
Oh, and while you have the cover off, does it have a lip jutting forward from the front edge? If so, grind or snip it off; it's been known to vibrate up against the engine oil pan and "saw" through it. New version doesn't have that lip, but the mod costs zero.
Eeeek, a Fram oil filter!.....
