Maintaining a Jobo CPP-2 or CPA-2

[John Powers]

What should owners do to maintain these units? I have the Instruction Manual #66048 (07/97). There are two pages devoted to “Processor Maintenance and Tips” and I have followed these steps. There is much good information here but I suspect there is more knowledge out there among our community.

Over the weekend I did the eight hour cleaning of the tempering tank, water pump and over all casing using heated water and “Processor Clean II”. This old serial # 13391 looks brand new now.

I have two packages of lubricant the guys at Jobo Ann Arbor sent me years ago. I am embarrassed to say that I have forgotten which lube goes where. Does someone here know? #95465 comes in a 70ml syringe. #93071 comes with a little plastic canister holding maybe ½ oz to 1 oz to be applied with a tiny plastic handled brush. Neither of these is mentioned in the two pages of maintenance or the index. All the gears on the lift are still lubricated from earlier applications, but maybe I should be putting some fresh in there.

As mentioned in another thread, I bought this unit second hand, sometime in 2004. The Ann Arbor crew sent me a new lift when I moved up to 4x5 and had trouble using Expert drums. In the last year I processed 250 sheets of 7x17 in a combined 2800-2500 tank and 100 sheets of 8x10 in an Expert drum. I only use Rollo Pyro to develop B&W film. I tray process print paper. When using the Jobo in a SS sink I plug it into a surge protector that then goes into a GFI outlet.

What do you know about these units that might help the rest of us extend the working life of our old Jobos?

Thanks,

John

Im curious to know as well- mine squeeks horribly almost every time I use it

Greg Blank will likely answer with more accurate info.

The syringe stuff is for the shaft for the gears that go from the front of the lift mechanism to the back where the main gear comes off the motor from what I remember in lubing mine years ago. It does get rid of that horrid squeak.

Also replying to J Powers...here:

The syringe is for packing grease inside the hole that the white transfer gears ride in on the lift arm. ATLs have two gears, CPE, CPA and CPP2 have one hole.You fill the hole with grease then insert the two part gear and snap lock it together.

Grease eliminates the squeek. You can also apply vaseline using a Q tip instead...same mission accomplished with a dime store item versus the $32.00 syringe of high priced brown grease.

The white tub is is even pricer it's ""Lithium" grease "Silkon" which you most likely can find state side for less than the 50$ per 1/4 gram Omega sells it for. Used on the backside of the Lift elbow. Lubed twice in twenty years probably enough

Maintance? Keep the knobs area free from water, wipe it immediately after spilling water or chemicals on this area. Periodically lube the lift including the transfer gears. Check the water pump impellor periodically for twisted hair lint or debris. Remove the water impellor guard by rocking it front to back noting the tabs. One of my recent repairs told me I should post videos on You tube. Since I set an account up I aybe do that....whadda all do you think?

Process clean is good algae control. Windex helps remove subborn fixer sulfer deposits.

I'm guessing it would depend on the vintage but.......Are the motors in the cpa-2 the same as the cpp-2?

As long as we're on the subject, what method is good for controlling the algae? My water comes through old pipes and I'm forming algea fairly quickly in the tub which is annoying to have to clean very often.
Another yes vote for the video, also.

As the OP I meant the thread to be open to all aspects of Jobo CPP-2 and CPA-2 maintenance. Please have at any aspect of that.

My water source is a rural farm well. I use a water softener and a 3 micron or 1 micron canister filter, which ever is available at Lowes, to rid dirt, taste and smell. I find if this water sits overnight and beyond, algae becomes apparent. I dump all water after a day's use whether that is one or more loads of film. I still get white sediment that I assume is lime. One eight hour wash with Jobo “Processor Clean II” cleaner eliminated four years of sediment.

Hope that helps.

John
