Subject: Gearbox oil type

Hi Tony,

I wonder if you could help me, I have a "marine"1969 Lister diesel SR2 coupled to a Lister reverse gearbox and Lister reduction gear but have no idea which type of oil the gearbox and reduction gear use, if you could advise me Id be very grateful.

Thanks, Neil.

 

ANSWER

Dear Neil

Go to this website & click the Union Jack - unless you can speak Dutch!

http://www.motoren.ath.cx/ (see note below)

Then download the SRM manual - that has both the mechanical and hydraulic gearbox in it.

From memory its OEP 80 (gear oil) for the reduction box and engine oil for the hydraulic gearbox, but its too long ago for memory to be relied upon. I have no idea about the mechanical box but I would expect it to be engine oil.

Hope this helps

Subject: Lister HL150 gearbox

Dear Tony,

Have just bought second hand barge, me and my partner are new to all this, anyway the main problem is that we cannot get reverse gear the selector goes fully back but still no reverse, would be really grateful if you could send me some ideas on this. It is a Lister HL 150 hydraulic reverse gear.

Many thanks Liz D

 

ANSWER

Dear Ms D

I think that gearbox has an internal adjustment under the small dome on the gearbox top cover. From memory this adjusts a brake band that is supposed to grip the reverse gear drum when reverse is engaged.

It has a threaded rod with a screwdriver slot in the top and an adjusting nut. The slot is held and the nut is turned. Lengthen the rod to tighten the band and shorten it to slacken the band. Unfortunately you have to put the top back on the test the adjustment. Also take care that you do not damage the gasket - it's fairly complex and if it fails you may end up with only ahead gear and no reverse or neutral.

Unlike most other hydraulic gearboxes I think this one uses oil pressure for neutral and astern, so lack of oil would leave the box in ahead, but with no neutral as well as no astern - its worth checking.

Having got the top off, I would try to see it the band still has any friction material on its face next to the drum.
