In place repairs happen all the time and are most often done properly and with excellent results. We are only cautioning the original poster that these repairs should not be done by someone learning as they go. DH Perhaps I should clarify my post above as follows: Even car mechanics recommend to replace gearbox instead of repairing it because it is difficult to overhaul.

So, is it fair to say regardless whether the gearbox is cheap or expensive, overhauling gearboxes is difficult to do by any mechanics except specialized mechanics eg from OEM? Jhunrey SO, what is the purpose of getting the step by step work instructions to overhaul or recondition gearboxes? Is it with intention to overhaul the gearboxes inhouse by own mechanics or to send the gearboxes to outside vendors like OEMs? So, is it fair to say regardless whether the gearbox is cheap or expensive, overhauling gearboxes is difficult to do by any mechanics except specialized mechanics from OEM?

Your comparison of automotive and industrial gearboxes is not valid for a variety of reasons. In actuality, the large industrial gearbox is much easier to rebuild in place than an automotive transmission would be and in many cases, an automotive rebuild in place is impossible by design. When a car transmission can be removed and replaced by a single technician in a fraction of the time it would take to rebuild in place; and then rebuilt in an assembly line process, it is a decision that has already been made for you.

As far as the OEM being the only one capable, that is not true. I have one client who regularly rebuilds their gearboxes in place with a tremendous record of sucessful work. They are all trained by the OEM and adhere strictly to the recommended practices that the OP seeks, but they are in-house, company employed maintenance mechanics at a site with drives built by only one manufacturer.

The more different manufacturers, the more procedures and the more challenging the OP's job becomes. Removal of a large industrial gearbox is by nature a much more involved undertaking that might double the down-time for a rebuild unless a spare is available. If a spare is available, it is still a major undertaking that might or might not take longer than the in-place rebuild. And spares cost just as much as the real thing. John is probably better suited to answer these questions from his years in actual gearbox repair.

I have strayed into the Beginners Forum. My posts might say that I am a Beginner but the grey in my beard says otherwise.
