    I was going to sub that part out to a friend anyway. I always used this guy at Trane and he does good work at a reasonable price. For about the last 6 years or so, we didn't do our own recovery in the office I worked out of which was a sub office. We always got the cast off tools from the main office and our recovery equipment was a POS that we were always repairing anyway. Finally, for the number of times a year we needed to pull the charge on a big machine (maybe 8 or 10), the main office decreed that it was cheaper to sub it out than time lost on repairs or purchasing new equipment. We often referred to ourselves as the red headed step children of the main office, but the good thing about that is they never bothered us as long as the customers were kept happy and the money continued rolling in.
    I think making us do more with less made us more self reliant mechanics. When they would send someone down from the main office to help out when things got busy and we in the middle of a teardown, they would invariably complain about how we worked. To us it was just business as usual. A lot of jobs that would be two man jobs up in the main office were done by one guy down here. We were spread out pretty thin at times.

    Well, I knew what my answer would have been, but when I present the job to my boss I want some opinions I trust that can back me up when he asks me if it can be done that way. I'm still trying to figure him out. I don't know if he is just real old school or if he doesn't know WTF he is talking about. He used to work for JCI/York before he came to this company. One of the things he wanted me to do was pressurize a chiller with nitrogen on top of R-11. That was one of my WTF moments. I didn't realize what he was asking at first and I asked him if the charge had been pulled or do I need to schedule it. He said no, add nitrogen to leak check it, then use the purge to pull it back out.
    The bearing job is one of my old accounts that I took care of for almost ten years and the customer is questioning Tranes diagnosis since the machine was rebuilt three years ago and the motor rewound and with new bearings installed then. He wanted to go with my new company when I left, but the bean counters in his corporate office wouldn't let him since Trane services all of their locations and you know how bean counters love consistancy. He sees this as justification to get me back in there.

    Well I guessing that if you dont have a good low pressure recovery unit you probably dont have the bearing press either ??? So how do you propose to do the job correctly ??

    Being a mechanical company, they do have a bearing press and an oven. I would just need to get the proper attachment if they don't have it and a shaft nut socket.

    When I was talking about not having a good low pressure recovery machine, that was at Trane.

    Your poor planning does not constitute an emergency on my part!!!!

    If his office did not have everything that they needed it was no ones fault but their own.

    There are probably contractors that get along just fine out there.

    But there is no substitute for working for the manufacturers. You have unlimited access to information, electornic data base, tech. assistance, confidential information and parts.

    For instance we had a big CVHE that was shaking and was out of warranty.
    At that point I was just following instructions from LaCross and probably took the machind down at least 5 times as they sent bearings, rotors, seals, gkt. kits and finally the part that made the fix. The Ball Bearing Bracket itself.

    Not to mention the rental chiller that sat there for a month.

    And all this with no down time to the pharm. plant.

    And at no COST to the customer.

    I don't beleive that the job could have been resolved the same way by any contractor.

    In short the ball bearing bracket (end bell of the motor).

    The casting was not machined parallel for the outer race of the bearing.
    Someone in LaCross had seen it before and sent a new end bell and that cured the problem.

    I had seen that on a vertical split case pump from B&G before.

    Anyone have the service bulletin that covers the bearing replacement? It's CTV-SB-33, I think.
