With Goerend's new tool that locates a lube hole directly feeding the C-3 clutch & patented PTO cover, you can get the much needed lube oil to the Allison C-3 clutches. The new PTO cover funnels oil to a hole in the trans case that supplies lube oil directly to the C-3 clutches. This oil would otherwise return to the trans pan unused. We have now directed it to the C-3 clutch pack to lube & cool this hard working clutch. We have created a jig tool to insure proper hole location when installing the Goerend PTO covers for the Allison 1000 and 2000 units.
