I have a Volvo Penta
fitted to a Volvo Penta
now appears to be working OK but the top gear
casing is uncomfortably hot when I run the engine
at 1600 rpm
whilst tied to the dock
. When I select reverse, the bottom gear
gets uncomfortably hot. By that I mean I can touch the casing for 2 or 3 seconds before pain sets in.
I know that dockside running is putting constant acceleration power through the gearbox but I would rather have a problem here than approaching the Panama
The casing does not get hotter and the bearings are being well oiled with no signs of any wear. The oil
is cooled internally by a raw water heat exchanger
I have dripped water
on the casing and it does not boil or steam off so it is well below 100 deg centigrade.
How hot do you think a gearbox SHOULD get??
Thanks for your help.
