View Full Version : CPA2/CPP2 lift + Expert Drums
hey guys!
A Jobo licensed service told me that its not good to use the 8x10 Expert Drum on the CPA2/CPP2
and that the only Jobo Drum that works with CPA2/CPP2 is 3006... i should forget about 3010 or 3005...
they didn't say why..
anyone has any experience?
yes. I've burned one up.
The older motors can't handle turning the big drums full of chemicals. Don't use more chemicals than necessary and you should be okay if you have a newer model. I don't know the serial numbers but a search will turn it up.

Here's the official word on the CPA2/CPP2 motors, from Jobo Bulletin B019:
____________________________________________________________________________________
Beginning production of the CPP and CPA began with a single bearing rotation motor.
CPP Serial # ARXXXX - 10593
CPA Serial # ARXXXX - 10312
1st Upgrade: Changed single bearing rotation motor to a double bearing rotation motor.
CPP Serial # 10594 - 20455
CPA Serial # 10313 - 13309
2nd Upgrade: Strengthened the rotation motor circuit to accommodate larger loads, i.e. 3000 Drums.
CPP Serial # 20456 - 21999
CPA Serial # 13310 - 21999
3rd Upgrade: Changed to a stronger rotation motor (same as used in the ATL's) and strengthened the rotation motor circuit to accommodate the stronger motor.
CPP Serial # 22000 - present
CPA Serial # 22000 - present

I'd have to check the serial number on my CPP-2 (I suspect it's one of the older weak motor types, since I bought it in the mid-90's), but I've been running the 8x10 drum on mine without issue since purchase. I've never loaded it down with chemistry, though.
My serial is CPA2 15351... where does this leave me? All Expert drums?

Run it until it dies

Based on serial number, it looks like mine falls into the 3rd Upgrade category; so, maybe, that's why I've never had any problems with the motor/circuitry.
