derived specs on Deutz 1011 timing belts

Hello all, Just purchased a Bobcat 873 with the Deutz 1011F engine, oil cooled, turbo diesel. Began the effort to replace filters and oil along with the timing belt. Spent time trying to find the tension specs for the belt. Finally gave up. As you know, nothing exists from Bobcat or Deutz as to what the timing belt tension is set to. After a lot of analysis I backed into what the numbers mean when we use the infamous Deutz tension meter. Bottom line is the meter measures force (in Newtons) used in deflecting the belt. The amount of deflection corresponds to a predetermined belt tension based upon the span distance and bending modulus of the belt. Sounds like a bunch of jargon but the Deutz meter is nothing but a customized device used in the "force deflection" method of measuring belt tension. Manufacturers usually provide the deflection force and we have to measure the deflection, force and determine the span length. This is what I have come up with:

Pretension = .73 lbf @ .166" deflection or 3.25 N @ 2.7 mm deflection
Final distrubuted (locked cam) tension = 1.82 lbf or 8 N corresponding to a belt tension of 25 lbf.
There is a bunch of background to these numbers so post away with questions.

I'm guessing this model isn't running a spring loaded tensioner?

We rebuild this model a few times a year, we do not have the fancy tension tool, the mechanic must just know what seems right. Also be aware, that it will loosen up after the belt beds its self in.

Your right, essentialy just adjust the slack out with a bit of tension then lock it down.. If your careful you can properly read the .75 lbf (3.25 N during freewheeling). Deutz has us then lock the cam to the shaft, spin the crank and the torque moment created by the a locked down cam distributes itself around the loop for the final 1.8 lbf (thats the 8N miracle reading). At this point the belt has bedded it at a 25 lbf tension. It's actually quite clever so why not just tell us!
Do you have any thoughts on how much dynamic moment the oil pump shaft will add when the engine is spun up? I cannot find any info. I suspect it is non trivial with cold oil. Hope someone knows.

I'd like to think that with constant load, there will be minimal shaft movement when rotating, so the figure shouldn't change.

Hopefully you are over thinking it, these engines are a little more complicated than most, but they do run very well.
