Lister Lh 150 Gearbox Manual
Basshunter All I Ever Wanted Acapella Device. Raw Message Hi there just had a baptism of fire today trying to fix a customers engine gremlins. After five hours tracked the problem down to the hydraulic gearbox. Basically when the box is in neutral, the engine runs fine, full rev range and smooth response. But I cannot turn the prop by hand and it seems to be locked tight. With the gearbox in either ahead or astern the revs die right down and the engine labours as if trying to pull the dock wall off.

Oh and there is a very delayed response to the throttle. I have tracked the problem down to the reduction box on the stern end, what is this likely to be? I have not worked on this before and would really like to find out the cause and remedy. Thouroughly checked fuel system and bled through, all fine no leaks.
Stern gland not over tight and not hot. Your help would be greatly appreciated. Oh and i am looking for a parts and manuals supplier for these in the Midlands cheers Towpath engineering Services. Raw Message Manual for box (but not reduction box) from the Dutch Manual Link on my website (address below) I trust you have physically inspected the prop to ensure it is not fouled - those symptoms scream fouled prop. This box uses hydraulic pressure for reverse and neutral. Ahead is obtained by no pressure, so if you try to turn anything with the engine stationary the box will appear to be seized. There is a triangular plate, facing backwards, held on with three bolts, plus a centre bolt on the gearbox.
Gently screw a setscrew (5/16UNF I think, but check) in until you have forced the ahead piston just far enough forward to release the ahead cone clutch. Autocom Delphi 2013 R3 Keygen here. DO NOT OVERTIGHTEN Something odd is going on, I would have suspected a brake band or cone clutch lining misplaced, but that should give a gear with the box in neutral.
From memory of 30 years - so I might well be wrong - the reduction box uses double helical gears so there should be no end thrust problems. But I suppose a bearing could be breaking up and simply jamming, however I would have expected the customer to complain about noise unless it has been gradually getting worse. It could also be band or clutch adjustment, but download the manual to see how that is done. I know you say you have narrowed it down to the reduction box, but unless you have taken it off I do not see how so unless I get more details I still feel it is most likely to be a box fault I trust this is of some help.

Which is, it's worth noting, a flippin' pain when you get an inflatable boat wrapped around your propellor. That was one of those hireboat experiences that afects how you have your own boat built.
In our case - not one of these gearboxes. Tony knows more about this than most of us put together, and his thought about the prop makes me wonder - I do think it's worth checking that - say - the alignement hasn't shifted jamming the prop.
