Thank you hardheaded.
So, its this split cylindrical bearing we are talking about:
#9231 Outer race and roller cage (6) that sits in the housing
and the (14) separate inner race #34091-08 fixed to the gearbox input shaft
This unsealed cylindrical bearing is designed to resist to very high radial load but is subject to abrasion and requires thin oil.
With the SKF viscosity calculator I find similar bearings require a broad range of viscosities to operate between +5 and 100°C and at engine speeds from 1K to 6K RPM (500-3000 RPM on the input shaft). A 10W30 seems fine for the IPB but is not thick enough for the compensator and for the bearing inside the clutch. It seems we're bound to loose one or the other(s)
Coming back to the original topic IMO the Hayden tensioner will better protect the chain than the heavy duty cylindrical IPB. As many said, its a cheap insurance.

I was told they were on backorder???
Will you be using the same primary case gasket or putting a new one on?

I've always reused the same gasket since I've had Harleys and if I take them off nice and easy and correct torque when going back on, I've never had any leaks.
here is a link from where I ordered mine, should recieve by the 7th.

What is shown on your link is this:
The model I want to use has two mounting points:

It should be just the generic image they give on their add. I'll see when it gets here.

I Just had the IPB replaced on my 2010 ultra with just under 17000 miles. Tech said it was due to a poor design of the IPB and HD had a new IPB that would not fall apart as quickly. He told me the bearing cage on the old bearing was plastic. The new cage is metal.

When they changed yours to the upgraded steel cage did ya get a price break ? Sounds like the same thing as with the compensators.

Many bearing manufacturers mention this in their specs, so the "one oil for all holes" argument could be incriminated in the serial failure of the IPBs.

Got mine installed and could tell an immediate difference going down the road. Much smoother, especially in throttle transitions. No more herky jerky. Seems to shift a little smoother as well. As far as I'm concerned it was money well spent.
That's the first time I've ever heard that spec. You got a link for more information?
Did you know that plastic cages are designed to operate in pure mineral oil at 80°C under continuous duty but disintegrate rapidly ( ̴2Y) when typical EP additives are mixed in the oil?
