Glennaagesen Posted June 17, 2018 Share Posted June 17, 2018 Hi there When it comes to oil in the gearbox on a K60 pack, it says on the dipstick “OMD90”. Is that an equivalent oil as “EP90” ? Quote Link to comment Share on other sites More sharing options...
wally dugan Posted June 17, 2018 Share Posted June 17, 2018 OMD 90 is not the same as EP90 OMD 90 is SAE 10W-30 OIL Quote Link to comment Share on other sites More sharing options...
David Herbert Posted June 17, 2018 Share Posted June 17, 2018 The FV430 family specify a straight SAE 30 oil in the engine, transfer box, auto box and steering gearbox. Multi grade oils were not available when these vehicles came into service but I doubt that 10W-30 would cause any problems except possibly in the auto box.. However people have been known to put EP90 in the steering box which results in no brakes or steering. If you put auto trans fluid in the auto box you get very harsh shifting and very wrong choices of gears as it can't tell what is happening. Often overlooked is that you must make sure that the fuel pump governor is kept topped up with red auto trans fluid (any version of Dextron) as it is possible to have a catastrophic engine runaway if the level gets low. If that happens you have a very short time to press the red emergency stop pedal in front of the steering levers. ONLY the final drives get EP90 but also remember to grease the final drive seals through the grease nipples on the outside face of the hubs. As with the suspension arm pivots, the grease acts to push out muck and water as much as to lubricate the bearings so must be done regularly. Have fun David Quote Link to comment Share on other sites More sharing options...
Glennaagesen Posted June 17, 2018 Author Share Posted June 17, 2018 Great, thanks for info. Reason for my question, is that I do not get enough power from the gearbox. Engine runs perfect, and gearbox turns, until so much resistance. Up hill e.g. Im considering that the oil must be replaced. What the view on that theory?

wally dugan Posted June 17, 2018 Share Posted June 17, 2018 (edited) if you have never changed the oil in the gearbox it could not do any harm for the record DEF-STAN 91-113 LUBRICATION OIL OMD 90 also some GEARBOXES AUTOMATIC GEARBOXES and TORQUE CONVERTERS . SAE VISCOSITY CLASSIFICATION 10W-30 Edited June 17, 2018 by wally dugan Quote Link to comment Share on other sites More sharing options...
andym Posted June 18, 2018 Share Posted June 18, 2018 If you've never done it, change the gearbox oil and filter, making sure the level is correct as per the instructions on the dipstick. Too much oil is as bad as too little. As David says, use straight SAE30 mineral oil, available as a "classic" oil from many suppliers.
