Detroit Diesel — Install camshaft assembly on engine (Compact Geartrain Assembly)
Repair & overhaul
From a Detroit Diesel service manual — check it applies to your exact model before use.
Applies to: Detroit Diesel Series 60 engine
Before you start
- Do not bar the engine over with the timing pin installed; the timing pin is designed to break.
- If the camshaft gear cover bolts and/or the camshaft cap bolts are tightened down with the camshaft gear out of time, damage to the camshaft gear cover and timing pin will result.
Procedure
- Install camshaft alignment tool J 45946 on the camshaft gear cover and through the camshaft gear, ensuring the pin enters the timing hole in the backside of the gear cover.
- Verify the timing pin is in the crankshaft locator hole.
- If the adjustable idler gear was removed or replaced, remove the cover plate and loosen the three hub retaining nuts; install tool J 46306 to hold idler gear hub at middle of travel.
- Ensure two seals are properly installed in camshaft gear cover.
- Apply RTV along the split line on the gear case.
- Install two guide studs J 46302 into gearcase; using lifting tool J 46305 lower camshaft assembly into position on bearings and gear case.
- Remove alignment tool and guide studs and install camshaft gear cover bolts by hand; tighten four attachment bolts until cover just contacts gear case (do not torque).
- Reinstall the alignment tool to verify timing is correct before installing the No.1 camshaft cap.
