Inspection and repair service on ZPMC GFH1600.16.A1A-00 gearbox

Scope of work:

We performed an inspection and repair on a gearbox ZPMC GFH1600.16.A1A-00.

We got this ZPMC GFH1600.16.A1A-00 in our plant in February 2016 from one of our Netherlands clients. After doing a test run, we transported the gear unit back to our client.
Recommendations after visual inspection:

Machine gearbox casing. Both split lines and bearing pockets of input, second intermediate and output shaft. Machining split line of gearbox will affect centre distance of first and second gear set, therefore re-bushing or cladding of the first intermediate shaft bearing pockets will be necessary. Adjust axial clearance, between bearing covers, during re-assembly of the gearbox. Perform a test run of gearbox.

Shaft sealing:

The maximum circumferential speed of the input shaft seal surface is (at idle speed) relative high and therefore it is recommended to increase the shaft seal hardness to prevent any oil leakages caused by a worn shaft surface. A modification of the shaft seal design of the input shaft can be realized by laser cladding, (ceramic) coating or the use of hardened wear sleeves.
