description

The 573-9121 is cast iron camshaft support housing for C7.1 engine. It contains bearing seats, oil galleries and threaded holes to hold camshaft, bearings and thrust plates. Vibration and contaminated oil cause seat bore wear, blocked oil passages, stripped threads or housing cracks. Worn bore leads to excessive camshaft clearance, abnormal noise, unstable oil pressure and rapid cam lobe failure. Its hole layout and oil circuit design are exclusive for C7.1 and not interchangeable with C4.4 or C6.6 housings.

FAQ 

1. Does 573-9121 fit C6.6 engine?
No. C6.6 and C7.1 differ in bore spacing, oil route and bolt layout, non-interchangeable.

2. Can lightly worn housing bore be repaired by reboring?
Repair is only allowed within wear limit. Cast iron housing loses rigidity after over-boring.

3. Can I just replace bolts if threads are stripped?
No. The threaded base is damaged. Housing replacement or thread insert repair is required.

4. Does this housing come with camshaft and bearings?
No. Only the housing itself. Camshaft, bearings and thrust parts are sold separately.
