Lister lh150 gearbox adjustment Although the Lister hydraulic gearbox fitted to SR and ST engines is a reliable unit requiring very little maintenance, over a period of time the friction surfaces of the clutches can experience wear.
Helping out a friend who has a LISTER SR2 in his boat. The AHEAD function of the gearbox works well,but reverse will not engage until a lot of throttle is applied. Have down loaded adjustment instructions,looks like the brakeband may need adjusting? Nipping up the brakeband is simple enough so will try it and see if the problem disappears.
Question is,is the hydraulic system on these gearboxes bullet-proof,is it best to check that side of it out as well? I have rebuilt dozens of marine reversing gear units,but never a lister version. Have you checked the dipstick in the reversing box. Being short of oil would produce the symptoms you describe Spent some time on this gearbox today. Brake band adjustment is correct,nipped down and 3 full turns back. Ahead adjustment correct.
Drained the oil and refilled with EP 80/90. The reverse function engages sweetly sometimes,on some occassions it fails to engage without lots of revs and a few seconds delay. A kind and knowledgable chap who repairs and restores listers suggested altering the hydraulic pressure by shim adjustment. Looks like the problem may be more complex than it first appeared to be.
Any one have any more tips? Spent some time on this gearbox today.

Any one have any more tips? The hydraulic pressure is adjusted by adding or deducting shims from behind the relief valve spring which is situated behind the forward and reverse lever unit on the port side of the box. Adjustments to this should be done with a pressure gauge screwed into the plug port on the boxes top plate,but for the small increase in pressure that you need just a calculated guess would surfice.Probably a weak relief valve spring,but add shims to increase pressure.There are O ring seals on the F&R lever unit behind which the relief valve,spring and shims are so go gently.
