lx665 gearbox mod

Mike10, I redid the gearbox lube system as you described by replacing the lower front mounting bolt with one with a hole in it and adding a 1/2 inch half coupling to the chain case cover 2 1/2 inches up from lower edge to increase oil level. Have you seen any trouble caused by just using the bolt to maintain the oil level in the case or is there a way to install the funnel system that the ls160 uses to constantly add oil. I have not been able to find any diagrams or pictures of the funnel to see if retrofit would work. thanks

The only loaders which used the funnels are the large frame loaders such as the later LX865, LX885, LX985 and the LS180 LS190. The later LS160 and L160 use the drilled bolt. The gearboxes are completely different between the mid frame loaders and the large frame loaders. There is no advantage to the funnels except it is the only way to get oil into the gearboxes on the large frame loaders. When you repair a gearbox with funnels you must fill the gearbox first so there is oil in it because it takes too long for the oil to flow into the box through the funnels after a rebuild. With the drilled bolt oil reaches a level in the box that is equal to the chain case oil level. I like to hold open the breathers on top of the gearboxes to make sure oil is getting into the box and not air locked but I do not think it is necessary.
