Crankshaft Pulley: Removal
WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley bolt. Before any repair required loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special tools, otherwise severe engine damage can occur.
CAUTION:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan can cause engine failure.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING AND LIFTING article.
- Remove the fan and shroud. For additional information, refer to ENGINE COOLING article.
- Remove the accessory drive belt. For additional information, refer to ACCESSORY DRIVE article.
- Remove the valve cover. For additional information, refer to Valve Cover in this article.
- Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at top dead center (TDC).
- The hole in the crankshaft pulley should be in the 6 o'clock position.
- Install the special tool in the slots on the rear of both camshafts.
- Remove the engine plug bolt.
- Install the special tool.
- Assemble the special tools using 4 hardened washers in the locations shown.
- Using the special tools and an air impact wrench, remove the crankshaft pulley.
- Remove and discard the crankshaft pulley bolt and washer.
- Remove the crankshaft pulley.
CAUTION:
Failure to position the No. 1 piston at top dead center (TDC) can result in damage to the engine. Turn the crankshaft in the normal direction of rotation only.
CAUTION:
The special tool 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
NOTE:
The camshaft timing slots are offset. If the special tool cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.
NOTE:
The special tool will contact the crankshaft and prevent it from turning past TDC. However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position during the crankshaft pulley removal and installation.
CAUTION:
The crankshaft must remain in the top dead center (TDC) position during removal of the pulley bolt or damage to the engine can occur. Therefore, the crankshaft pulley must be held in place with the special tool and the bolt should be removed using an air impact wrench (1/2-in drive minimum).
CAUTION:
If the crankshaft sprocket diamond washer comes off with the crankshaft pulley, it must be installed back onto the crankshaft, or engine damage may occur.
