Troubleshooter
I attended on board of a roro transport ship and carried out service Viking hydraulic motor 63 series.
Nowadays I revise my old article and I remember my experiences on board commercial and offshore vessels as hydraulic troubleshooter.
I attended together with team of fitters on board of a roro transport vessel and serviced a Viking hydraulic motor 63 series.
On this job I had a good cooperation with the ship crew and specially with the superintendent. The guy was very understanding and the ship crew was very helpful. Every time when we were asking some tools or some help with ship crane the answer was “yes”. It was a good atmosphere on board.
Service Viking Hydraulic motor 63 series
The motor was for a one side stern ramp driving a winch and was located outside on deck side. The condition of the machine was bad. The assembly was rusted and full of leakage and dirt. Furthermore, the motor valve block was rusted and could not be seen the dismantle bolts. It looked like was not in use for a long time. But curiosity that the steel wire rope was new. Today I think after I checked the pictures maybe the ramp was in operation until the motor broken and the winch cannot lifted the load. Therefore, was in use but on the old vessels like this one this procedure is common, if is working the machine just use it until stops. Maintenance not followed regularly and because of this, the condition of equipment it was as described.
We fabricated a support in the shape of a C-frame to dismantle the motor from the winch bracket. Also used a hydraulic ram and a heating torch to pushed the motor out.
We appreciate the ship crew for slackening the mounting bolt of the winch drum, which eased our work.
