Spirit R/T L4-135 2.2L DOHC Turbo (1991)
Camshaft: Service and Repair
Fig. 36 Camshaft Bearing Cap Removal
Removal and installation of camshaft requires separation of camshaft sprocket from camshaft. In order to maintain camshaft, intermediate shaft and
crankshaft timing, the timing belt is left indexed on the camshaft sprocket while the assembly is suspended under light tension, Fig. 36.
When removing camshaft sprocket from camshaft, adequate tension on sprocket and belt assembly must be maintained to prevent the timing belt from
disengaging from the intermediate or crankshaft timing sprockets.
NOTE: Failure to maintain adequate tension on timing belt may result in incorrect engine timing.

Cylinder head must be removed from vehicle before removal of camshafts is possible.
1.
Mark rocker arms to ensure installation in original position.
2.
Evenly loosen camshaft bearing bolts in sequence shown in Fig. 12, until all bolts have been removed.
3.
Remove thrust plates from rear of camshafts. Thrust plates are not the same thickness and cannot be interchanged. The intake camshaft uses a
wider thrust plate than the exhaust.
4.
Before camshafts can be removed the cam seal must be removed first. Use care not to damage seal surface of the camshaft.
5.
Using a screwdriver placed against the side of the cam lobe, push the cam out of the head, Fig. 38. The cam seal will be pushed out by the cam.
6.
Slide the camshaft out of cylinder head using care not to scratch bearing surfaces in the head.
7.
Check camshaft lobe height in center (contact area) and on shoulders of lobe. If difference in reading exceeds .010 inch (.25 mm), camshaft should
be replaced.
8.
Lubricate camshaft journals with clean engine oil and carefully install camshaft into head.
9.
Install thrust plates and tighten to specification.
10.
Install new cam seals.
