The Bosch EFEP 515

ON The EDGE OF THE COMPUTER AGE

This Bosch EFEP 515 was produced in March 1979 and was the "big brother" of the 8 plunger EFEP 270. It's represented by one bench in our shop and is a little rougher around the edges than our EFEP 385As or 270, but that doesn't make it any less capable and is regularly used for fuel injection pump testing. 

Though currently set up for 6-plunger pumps including those commonly found on the W113 Pagodas, it was built to accommodate up to 12 plungers and, with higher horsepower capabilities, is intended for larger diesel fuel injection pumps made for agricultural, trucking and marine equipment. 

Like the EFEP 270, the body is constructed from bent sheet metal, a change from the complex aluminum casting of the EFEP 385 and earlier models, making the 270 and 515 cheaper to produce, if a bit less indestructible.  In addition to its construction, the transmission was redesigned to reduce cost as well as removing most sound-deadening materials from the interior. While it's a bit louder than our other benches for these reasons, it is still a reliable member of the shop and is regularly used to test pumps before and after restoration.

 

We plan a full restoration of this bench in the coming months so make sure to check back as we get that process underway.
