This document is a single service-procedure illustration showing removal (or installation) of an engine crankshaft rear main oil seal. The line drawing depicts the rear face of an engine block/rear cover with the seal area exposed. Two special service tools are called out in labeled boxes: tool 100-001 (shown as an impact slide hammer style tool being used at an angle) and tool 303-519 (shown engaged in the center of the seal area with a threaded bolt/adapter). The illustration reference number A0094664 appears in the lower-left corner. Per the uploader's filename, this page pertains to a 4.2L engine rear seal procedure, though the illustration itself contains no text stating year, model, or engine. A reader can learn which Ford special service tools (100-001 and 303-519) are used together on the crankshaft rear seal and roughly how they are positioned against the rear of the engine, but no torque specifications, part numbers for the seal itself, or step-by-step instructions are included on this page.
