The only issue my D2 has had was the plastic lock down finally broke.
Ordered a new one and haven't worried about it at all. Been in the family
since new ; ) The replacement was added about 15 years back. still works
great.

The D-II and its successors were a great basic design for an enlarger
but they are sort of mechanical monstrosities (and I say that with
a lot of love :) Over the years I've done a fair bit of maintenance
and upgrades on mine and this has necessitated taking the think apart
and reassembling it from time to time. For that reason, years ago I
bought a Versalab laser enlarger aligning tool which allows you
to tweak in the negative stage, lensboard stage, and easel into
parallel planes.
Now, having said that, I'll make two observations:
- Being the mechanical monster it is, there is no way to get the D-II
into "perfect" alignment. If I get it right when the head is down
low, it's off a bit with the head all the way up and vice versa.
For this reason, I generally aligned it with the head as high as it
will go on the assumption that misalignment will be most visible at
high magnifications.
- You do NOT have to take the focusing stage apart to clean it as was
previously described. Just do the cleaning/lubing Richard and I
recommended
with the whole business in place and move the focus knob back and forth
to get to the entirety of the rods. That will save you from realignment
hell ... assuming your enlarger is aligned in the first place.
