Install camshaft drive gear (4) on camshaft (2) if camshaft drive gear (4) has been removed. There are two methods that can be used in order to install camshaft drive gear (4) on the camshaft. Preferred Method - Mechanically press camshaft drive gear (4) on camshaft (2) without heating camshaft drive gear (4).Alternative Method - Heat camshaft drive gear (4) to a maximum temperature of 205 °C (400 °F) for no more than one hour and manually install camshaft drive gear (4) on camshaft (2). Do not use a torch to heat camshaft drive gear (4).

Note: All 3408E Engines have a balancer gear that is located in the flywheel housing. The balancer gear is driven by the crankshaft or the camshaft. The balancer gear has a timing mark. This timing mark must be aligned with the timing mark of the gear that drives the balancer gear. If there is access to the rear camshaft gear through the flywheel housing, the rear camshaft gear may be removed without removing the flywheel housing. If the balancer gear is driven by the crankshaft, the camshaft rear gear can be removed and installed without regarding the timing. If the balancer gear is driven by the camshaft rear gear, the timing marks on the camshaft rear gear and the balancer gear must be aligned when the camshaft rear gear is installed. Refer to Disassembly and Assembly, "Balancer Group - Remove" and Disassembly and Assembly, "Balancer Group - Install". 3412 Engines do not have a balancer gear. A dowel in the rear of the camshaft positions the rear camshaft gear on the camshaft. The rear camshaft gear is secured to the camshaft with four bolts.
