Inspection and repair on ZF ZFW43100 NR gearbox

The state of the gearbox can be considered as good, only minor running marks were observed on gears and bearings. Furthermore, the gearbox externals and engine room were very clean at the time of the inspection.

Since no drawings of the gearbox were available it was not possible to determine all bearing positions. It can be expected that a combination of radial and axial bearings is present on some shafts, however these where not accessible through the bearing in front. If the thrust bearing is severely damaged it could transfer damage to the next bearing on the shaft by means of indentation of debris, no such damage has been observed.

Inspection and repair on JAHNEL-KESTERMANN PGVC-630-435 gearbox

Scoop of work:

• Inspection Propulsion gearbox, Jahnel Kestermann, PGVC-630-435

Bearing pos. 1 of the input shaft, shows a gray dull appearance. No further damages were observed. However no information about the running hours of the gearbox were available.

The main engine running hours are exceeding the recommended gearbox running hours.

If the gearbox hasn’t been overhauled in the past, GBS recommend to replace the bearings during an overhaul. This to avoid an un planned, destruction repair. Please be aware no indications of significant wear is observed, however the condition of the expended bearing lifespan can change rapidly. <
