Reply to "ZF oil cooler"

Interesting, Peter. Looking fwd to seeing more photos. The only 'factory' oil cooler equipped ZF I've seen utilized cast-in-place bosses on the right side of the transmission section. Those connect to drillable passages inside, along with a funnel pickup that uses the ring gear to keep it full and gravity-feed an external cooler, thus no pump needed once the lube is hot. Some of the small-block GT-40s had this rig, but the pickup funnel only functions if the transmission section is upside-down as in the GT-40 or the Mangusta. And those only used 2 flex lines.

The rear cover casting looks a little different than ours, and not just because of the lower oil fitting. The top oil fitting is in the place of a lube dipstick used in early cars & the stock vent fitting over the ring gear is missing- maybe plugged?

Wonder who rigged this one, or if this ZF is indeed off a 'Fendt Roller' with it's large remote lube tank, as someone suggested. Fendts were an early ZF-equipped road-grader used in Europe. More info on the Web under Fendt Roller.
