Overdrive Maintenance

Post by Raggylad »

Have just done a 6,000 mile service on the 110 V8 (LT95 box) - first that I have done myself since fitting the overdrive.

Given that the unit is mounted well above the transfer box oil filler plug, how do you check that it has enough oil ? There's plenty in the T box as careful removal of the filler plug has it gushing out !

Can't see an obvious level plug for the o/drive unit, though.

Raggylad. The LT95 overdrive is constantly splashfed down the 2 channels on the inside next to the mainshaft cog. Unless the 2 holes at the end of the channel become clogged there should be no oil starvation.

im pretu sure theres a plug on the back, your still supposed to drain it, and top it back up on oil changes ...splash lubrication then keeps it full (hopefully) ...there not that robust, so be gentle with it

I think the Lt95 unit is strong enough provided you dont use them in the low gears. The V8 torque is just to much. Use them as a 5th gear and they go on forever. Look after em as there are very few replacement spare available now.

Thanks. That confirms what hoped was correct. Only ever use it in high ratio 4th (ie as a 5th gear) so hopefully it should give good service. The increase in mpg on long runs is very noticeable - as is the reduced noise !

Hi,

as far as I know, you can use the OD in 3rd and fourth gear. It`s very usefull if you run up a hill, you have a gear between third and fourth. If you change gears from third to third with OD and then to fourth you have realy good acceleration.

The only reason i only used my overdrive as a 5th gear only was so it would last longer. Yes i agree that the warning plate inside the cab did state to use the overdrives in 3rd and 4th only.
