[T3] Front axle beam question

I've sent you a scan of the Haynes diagram, which confirms your measurement.
It also looks like the same drawing as the Bentley!  Not much help, then.  
OTOH, why should there need to be a gap between them?

Subject: [T3] Front axle beam question

A month or so ago I had to do a LOT of work on Gary Forsmo's front axle
beam, after the fixed socket for his RF torsion bar tore loose. 
We replaced the beam and then replaced some of the bushings in the used
replacement beam. It was a lot of work and I had to make a number of tools
to salvage and install bearings and bushings.

In that process I have looked at fig. 8-23 in chapter 7. That's the one that
shows how deep into the beam each bearing should be positioned.

The depth for the lower needle bearings is 4.5-5.5 mm, but I measure the
depth of the sleeve portion of the seal that gets pressed in there
afterwards at ~5 mm. That can't be right.

I'm measuring a used lower seal. Keith, do you have a NEW lower seal that
you can measure? Does anyone have a beam with a lower torsion bar removed
that they can measure the depth to the face of the bearing?

It looks like a mistake in the Bentley, but it might be due to rust in the
inner steel reinforcement of the used seal that I'm measuring.

Let me know.

thanks,
