StudioSpot CMY~how to realign the 4 dichroic wheels

I am cleaning / P.M.'ing our Studio Spot CMY units. I removed the four cmy wheels to clean them and now have a few questions:

1} how should I realign them when assembling the unit. - I noted that all wheels have holes that line up at either towards the center {beam path} of the unit or the flag motor before I removed them, can I just use that as a guide?

2} do the three little cogs & the raceway between each pair need to be lubed? - I have high temp caliper lube. should I clean this area out & re-grease it with several lite dabs? They looked as if they had been greased previously, but they cam from the same people that gobbed lube all over the iris of one of my studio colors.

I ask the wise wisdom of all, so that I may have fewer problems later. That & I don't want to make a bigger mess than I have already.:o

    The trick is keep the cleaning element wet and any downward pressure you do MUST be supported from below. Use long depressors about 6-8". I personally use a 12" hex wrench 3/32" wrapped in a lintless paper towel that I unwrap as I go to always have clean wet paper available.
    I move the dicro keeping the cleaning tool in one place, this works best for me, with the assembly still in one piece.:D

    The only lube I use is KRYTOX from DuPont. Chris at HES knows where you can get a tube for about $30. Avoid it getting on the glass like the plague!:nono:
    I never take these apart unless the dicro's are broken.

    Look very carefully at where the top of the lock ring is on your others. This is key. A few hundreths of and inch too far down or up and all you will get is errors. I finally made a depth gauge as a start point that hits it right on often after many tries and shaving the gauge down to just the right point.

    Took me 6 tries to get it right and even the its hit or miss on the pressure.
    Bout drove me nuts.:aargh4:
