1977-79 Models
The 240D and 300D have an injection timer drive installed in the end of the intermediate gear shaft. Injection timer drive is pressure lubricated. Use care when servicing engines, as bores in bearing bushing have been eliminated in newer design.
Never use a new injection timer and bearing bushing with earlier version intermediate gear shafts, since no oil would reach bearing bushing. However, the new intermediate gear shaft may be used along with previous injection timer and bearing bushing. Never install only a bearing bushing separately.
