Shorter Bolt Used To Hold Oil Pan Drain Cover{1302}
Usage:
3500 Industrial, Marine, Generator Set And Locomotive Engines
Description of Change: A shorter bolt is used to assemble the oil pan drain cover to the oil pan. The former bolt could bottom out in the bolt hole before the cover could compress the O-ring. This allowed the cover to leak. The new shorter bolts will not bottom out.
Adaptable To: The new 0L1351 Bolt is a direct replacement for the former 0S1594 Bolt. Four bolts are needed to hold the cover in place.
