Installation
Installation in reverse order. Position hub -arrow- on injection pump shaft. The landing spring on the injection pump shaft must fit into the hub groove.

Screw the nut -arrow- onto the thread of the injection pump shaft. Position stop on toothed pulley and tighten nut -arrow- hand-tight. Turn the injection pump sprocket using the stop -T10051- until it can be blocked by the lock -T10492-. To do this, insert the locking pin -T10492- into the fork -2- of the hub and into the hole -1- located behind it in the mounting bracket. Unscrew nut -arrow- again. The injection pump toothed pulley should be tightened enough so that it can still be turned, but so that it no longer wobbles. Install toothed belt. Install the high pressure fuel line.
