    Jobo CPP/CPA drive grease

    Think it's about time I gave my Jobo a bit of TLC.
    I know you can buy the grease on ebay, but as I'm in the UK it really doesn't look like a very cost effective option.

    Anyone know what grease to use on the drive and are there any instructions online anywhere?

    Thanks
    Ed

    Ed,

    A couple of years ago I asked about general maintenance of a CPP-2 on the Large Format Forum saying that I had bought the two kinds of grease from the former US Jobo distributor, but could no long remember which grease went where. Following are the answers I got. Gregg Blank at the time did the Jobo repair work for the current Jobo distributor Omega Satter.

    At a later date Gregg posted that Omega Satter is no longer servicing Jobo and Gregg, who is a regular on the LF Forum, is doing the work independently. There are of course other people in the US doing that sort of work as well.

    I hope these answers will at least get you started.

    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. Gregg Blank
    Someone else asked about a squeak and this was the answer.

    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.

    I used vaseline, (or probably the cheapest generic petroleum jelly), it seems to work fine. That squeak is pretty hard to take.

    I use dielectric grease for the white transfer gear and it works great. Why that? A) The little squeeze tube fits right in the hole B) The grease is waterproof C) It is about $3 and available at any auto parts store and Kmart, etc., D) It is silicone based, not petroleum based and won't harm plastic or rubber E) and (per the product description)
    ideal for lubrication of plastic & rubber.

    It is good to see a place that services darkroom equipment but that site lists neither prices, products or a location.

    That site was last updated in 2008.

    Use Vaseline which is also prescribed by Jobo service. In the water bath you can use an anti algue preservative. Then it's not a problem to use the Jobo over more weeks. Without you have to change the water frequently.

    In the ball bearings (inside the motor unit) you can use graphite. The control unit and motor units are pretty simple: 80-90's electronic stuff. The PT-100 is pretty acurate: +/- 0,2C is possible.
    Take also notice of the O-rings (Viton) behind the plastic srews. Especially when changing to the elevator unit.
    Also the "chicken fork" must just reach the pin on the wheel. Otherwise the unit is not going in reverse. You can adapt this by the allen wrenge on the central wheel.

    For the rest you have a minimum of maintenance on a CPE/CPA unit.
