Mp#11- Sled would not go back. removed the V26 solenoid valve assy. and cleaned out the check valve and orifices with solvent and air nozzle. It appeared to be clogged and dirty. Reassembled, checked operation, O.K. to run.
Also refilled with about 20 gallons of Rando 46 hydraulic fluid.
Mp#23- Nozzle was not heating (according to the tech). Found band clamp broken and the other one missing. He still wanted to change the band out anyway, so we did.
The ink pad printer nest assy appears to be loose but all the screws are tight on it. Mostly looks like slop in the xy table, except too much ? I also could not locate the manuals for it. The last time I knew where they were was inside the pad printer. Now no idea? I was going to see what kind of pm inspection it needed?
Call if there are any questions, have a great weekend.

10.14.10 D shift
Mp#15- Zone 1 overtemp.
Found the problem to be an incorrect thermocouple type. It had a "j" type and it should have been a "k" type.
There were 2 more J type in the MRO location where the K's were supposed to be and I almost made the same mistake that someone else had made, of putting one on. Instead I used a nozzle band K type and put it under the band on the first zone.
It is running good and staying exactly on temperature now.
Fixed the leak on MP#2.
Refilled 17 with oil and cleaned up the oil dry.
Checked out the milacron dryer DR17 and it is fine.
Checked out DR2, looped it out for a few hours and checked the beds, it is fine too.
Sent an email to one metal supplier to see if they can get us some brass peices for the sled shims the right dimensions that I measured tonight.
Be back at 2pm today.
Don't call, I won't answer....lol.

thermocouple calibrator
This is the lowest priced calibrator I found on the web at $195.00
http://www.omega.com/pptst/CL3512A.html
Omega's are a good brand and this tool will allow us to read the output from a thermocouple or send a signal to a temperature controller for comparison or tuning.
With as much machinery we use with temperature related controls, this tool is a must for any professional maintenance department such as Oreck's.
Check it out!

10.10.10 D shift weekend Sean
Mp#1- was making a squeaking sound when the screw was almost complete with building a shot. I greased the extruder bearing assembly but that did not appear to be the source of the sound. Then I actually put a little grease on the screw itself at the back of where it entered the barrel and it seamed to help. It did not run long enough to know for sure though and likely needs to be inspected further when it starts back up.
Mp#3- Had an E00240 error. Had to reboot from the boot card. Then we had to reload a set-up in it. Ran good the rest of the day.
Mp#5-had leaks from where someone just left a hose dragging beside the clamp.
Mp#2- Has a leak on the core/ejector hose valve block we installed for the steamer molds. When it goes down we can re-do it. Put it on a shared tasks outlook item.
DR#6- Finished what Ronnie was working on and replaced the desiccant in all of the canisters. Checked it out with the Dew point meter @-40. Tagged it and located it in the mezz room.
We have been seeing quite a few dryer issues lately. I followed the email suggestions for testing the touch pad on that Cincinnati dryer/hopper and it appeared that the display board is likely defective as jumpering the touch pad pins gave no response.
Checked out several DME cards, replaced fuses and tested them on a mold. They all worked fine. Tagged them and put them back out on the shelf.
Worked on PM's all weekend. Finding many issues with loose components on the loading system. Also finding robot Y-axis are getting loosened. Tightening them up, and other wrist components are getting loose.
One issue that we need to start getting into is the sled shims on these Nissei machines. Many are working out from under the sleds. I think we can get some brass the full length of the guides and secure it with screws? The problem is that we will have to schedule them down and figure out how to get them elevated enough to install them. Shouldn't be too much of a problem. I will measure all of them that need repaired now and come up with a parts list on Thursday morning.

I emptied all the overflow jugs on the presses, cleaned up the oil on MP-17, & vacuumed the pan on MP-6.
MP-4 I made an eoat for the rear steemer handle mold & installed it.
Somebody left the air poppet fittings out of the mold. We found them in tooling & installed them.
D-6 ran in the maint. shop for nearly 24 hrs. & the beds never did dry. I started pulling the desiccant cans to change them out.
