Information:
Camshaft
When reconditioning an engine, check the diameter of the camshaft bearing journals and the camshaft lobe height.Camshaft bearing journals have a diameter of 2.5000 .0005 in. (63.500 0.013 mm) and the minimum diameter worn is 2.4970 in. (63.424 mm).To find lobe lift (A) of camshaft, use the following procedure:1. Measure lobe height (B) of one exhaust and one intake lobe.2. Measure base circle (C) of one exhaust and one intake lobe.3. Subtract base circle (C) dimension (STEP 2) from lobe height (B) dimension (STEP 1). The difference is actual lobe lift (A).4. The specified (new) lobe lift (A) is: (a) Exhaust lobe ... .3071 in.(7.800 mm)(b) Intake lobe ... .3077 in.(7.816 mm)5. The maximum permissible difference between actual lobe lift (STEP 3) and specified lobe lift (STEP 4) is .025 in. (0.64 mm).
CAMSHAFT LOBE
A. Lobe lift. B. Lobe height. C. Base circle.With camshaft installed in the cylinder block, check end play. End play with new components should be .007 .003 in. (0.18 0.08 mm). The maximum permissible end play is .020 in. (0.51 mm).Camshaft Followers
Use an 8S2293 Magnet to remove the cam followers.
REMOVING CAM FOLLOWERSCam followers establish a wear pattern with the camshaft lobes. Identify and reinstall the followers removed. Dishing or circular wear pattern is allowed on the cam follower face, providing the wear face keeps a polished appearance. Replace the follower if the wear face is rough or shows signs of scuffing. A new follower can be used with an old camshaft, providing the lobe is in good condition. Put engine oil on the cam followers and the camshaft lobes before installing the cam followers. Use new cam followers with a new camshaft.Camshaft Gears
1. Remove screw (1) and washer (2) from end of camshaft.
REMOVING TIMING ADVANCE RETAINING SCREW
1. Screw. 2. Washer.2. Remove timing advance unit from the camshaft.3. Install puller (A), with spacer (C) over the shaft in the camshaft spacer (B) on spacer (C) as shown and remove the gear from the camshaft.
REMOVING GEAR (Typical Example)
A. 1P2321 Puller. B. 8S5579 Spacer. C. 9S9155 Spacer.To install the gear use the following procedure:1. Heat the gear to a temperature of approximately 400°F (204°C) before installing on the camshaft.
Do not heat the gear with a torch. Do not heat the gear to a temperature of more than 600°F (315°C). Heating the gear with a torch or to a temperature of more than 600°F (315°C) may cause the two drive dowels for the automatic timing advance to loosen and come out of the gear.
2. Align slot in gear hub with the pin in the camshaft. Install the gear on the camshaft with timing mark on gear aligned with timing mark on crankshaft gear. Be sure the gear is completly seated against the shoulder of the camshaft.
Do not drive the gear on the camshaft.
3. Align holes in weights with dowels in gear and install the automatic timing advance.4. Align pin (3) in washer with hole (4) in camshaft and install washer (2).5. Install screw (1) and
