Jasper Engines & Transmissions reminds installers to retain the oil pump intermediate drive from their Ford 4.0L OHC V6. This part is not supplied with a JASPER remanufactured engine.
“There have been occasions where JASPER received a core and found the oil pump intermediate drive left in the block,” says Randy Bauer, JASPER Gas Division Manager. “It is vital that the part be swapped over from the core engine, or replaced with a new one, or else the replacement engine will immediately fail due to lack of oil pressure.”
The Ford 4.0L OHC V6 oil pump is driven by the intermediate drive through a hex-shaped shaft coming from the pump located in the back valley of the engine. The intermediate drive is turned by a slant-cut gear that fits into a gear on the jackshaft which is turned by a timing chain.
There also have been instances where the intermediate shaft cannot easily be removed from the core. “The slant-cut gear of the intermediate shaft can hang on the jackshaft gear,” says Bauer. “The rotating assembly may have to be moved just enough to allow slack in-between the two gears, and easier removal of the intermediate shaft.”
