    Hello everyone!

    We are now dismantling an old Heidelberg 4 colors and 2 colors, and then re-install it again in different location. Any friendly important advice will be appreciated.

    Thank you :)

    Thank you, we plan to install it properly and do what we can to make it operational again. Because these machines are abandoned for more than 15 years.

    Make sure you prepare a proper concrete pad is the first thing.

    Thank you NotAGooner,
    Yes Sir, we hired a senior contractor for making the required concrete pad.

    Units are to be level both ways (0.02mm machine level). Gear mesh to be correct (they are numbered) 0.02mm gap on both landing pads between units. Spacers in correct bolt holes between units.

    And put the moss-rubber packing properly, specially on DS.
    Also the profile rubbers at drive side are a headache if you don't seal properly. I hate it.:mad:

    Sure gives the fingers a workout, Asif! After thirty years of sealing up Speed masters, I can crush diamonds between my thumb and forefinger.

    And also drive side - side frames must be in line not stepped or you will get oil leaks plus other problems

    Just curious, what's the worst dismantled press you guys ever dealt with?

    Not the worst but a problem we had on a Heidelberg CD after install, it would E-stop for no apparent reason whatsoever, after many Heidelberg technicians all looking at it, it finally came to light that one of the front head stop eyes was loose and kept moving and therefore triggering an overrun E-stop. :)

    Gotta be one that was shipped into the US from France...shotgun shell between lugs on main drive, 24mm bolt inside the storage drum (not even one of the unit bolts, much longer) and instead of unplugging feeder pilr motor Anphenol plug, apparently it was easier to cut the cable. Not to mention the one from Austria with air rifle BBs in every pump. Methinks..disgruntled pressmen :)

    It really depends alot on what kind of machine you are installing. Each machine has its little quirks you must look out for. Much advice already given here is great advice. When I install any machine, i like to get all the units on the pad before doing any fine leveling. This will allow the pad to settle down before bolting up units. Use a good level, preferably .04mm or better. Check side to side is check on the fountain roller and front to back checked at each side frame (depending on machine type). Some types of machines have tollerance stamped right into the side frame which is a good guide at where your level should be compared to where it was when first installed in Weisloch. Remember, this is only a guide. Shims between the side frames always trumps everything. Shims should have same contact on top and bottom before tightening bolts. Use a .01mm side frame gauge to check side frame to side frame on the drive side. Tolerance is less than .01mm. If your final measurement is +.01mm the next unit needs to be 0 or -.01mm. Deliverys can be tricky too. Ive seen many freelance installers move deliverys still attached to the last printing unit or coating unit. Bad idea. Always remove the delivery when moving the machine, even if its just to the other side of the building. When bolting up is done, always check gear lash. Gear lash can be anywhere from .03mm to .15mm depending on machine type and unit type. If you have never moved a machine before make sure you have someone with you who has or you will end up putting gears in the machine shortly after your first job.

    Next time when sealing drive side covers on Speedmaster 102 or CD102 get the rubber profile for the newer CD102s. they still seal great, they fit the older machines and the rubber profile has a 1mm hole in the core that allows the profile to be squeezed onto the 8mm gap in the covers there for saving your thumbs. Just a thought

    Thanks for the advice exheidmech.
    I always used impression cylinder for leveling on 102s, I only leveled the GTOs that way. Am I doing it wrong?
    As exheidmech mentioned, there are some numbers stamped on lower part of the side frames, these numbers indicate the lengthwise leveling to be up or down towards the delivery or feeder. +numbers mean up towards delivery and -numbers mean down.
    Also make sure to set the lateral ink distribution at proper position when bringing two units together.

    I hope this helps.

    Recently my friend installed a 4 color press, all the cables were cut instead of unplugging and were shipped in a barrel.
    It took more than two months to figure out which cable goes where.

    Nope, lateral leveling I do in different areas depending on the machine. SM and CD 102 I do on the impression cylinder as well. With the CD102 you do need a special prism or plate to put on the cylinder because of the larger cylinder diameter. GTO, MO, SM52, SM74 I will level off the fountain roller. Without knowing what kind of machine the OP is removing and installing I gave my generic fountain roller suggestion.
