    • Do NOT remove 3 focus scale calibration screws. I actually did that when attempting disassembly. And luckily, I also marked the original position before that.

    • I tried to remove the front element group first. But the thread is some how locked and impossible to turn using my current tooling. So I gave up, and most cleaning does not need to remove front group.

    • Remove focus ring rubber. Take your time, it's a huge piece and might be glued.

    • Remove 2 focus stop screws. Your's might be in different holes. Also you may like to calibrate that. There 3 holes at the infinity end, and 2 at the close-up (8m / 25 ft) end.

    • READ THIS FIRST! In the following step, rotate slowly, and apply gentle force pulling front and rear apart, and mark the position of separate.

    • Rotate the rear half of the lens, towards close-up direction (CW as looking downwards), pass 8m/25 feet mark and continue, while applying gentle force pulling rear part up, until they separate, mark the point.

    • When assemble them back, attach from this angle/point.

    • The front tube, thread on the inner side.

    • The rear tube, thread on the outer side.

    • This is just a partial tear down. This lens is extremely well made, and very very precise.

    • Until this point, this is a reasonable "maintenance teardown". And you can do most mirror and lens cleaning and grease replace.

    • Putting them back from the point/angle you marked in previous step, the focus scale does not need a calibration.

결론

To reassemble your device, follow these instructions in reverse order.

I am looking for more understanding of this breakdown. I have questions about the fragility of the components and how to clean the interior of the front glass of mold spores. Additionally i would love to understand how to calibrate its focus. Can you advise?

This is a professional lens, built very tough. Primary mirror cleaning is quite easy. but front element is kind of tricky. because there’s an inner thread there covered by damping oil/grease. Maybe you should try remove it from the front. remove the filter/cap thread ring first(My cap used to stuck with this ring so I‘ve got this far)…

In step 3, there are 2+3 screw holes at each end , those are for focus ring stopping screws. 3 for inf end and 2 for close end (if my memory is correct). But this is for adjustment instead of “calibration“. By my guess a giant lens like this could never be calibrated due to the TCE of aluminium tube. that’s why the focus ring is allow to go beyond inf.
