SEAT GP-SUSPENSION 2208634 - Caterpillar

Use the square drive on stud tensioner support (6) to loosen the nuts until the nuts contact the stud tensioners. Do not apply more than 100 N m (75 lb ft) of torque.If the nuts will not loosen, Repeat Step 18 and apply an additional 5 MPa (725 psi) of hydraulic pressure.
Slowly release the hydraulic pressure. After the hydraulic pressure has been released, disconnect the hoses from the stud tensioners.

Note the location of the tab on the end of crankshaft main bearing (15). A corresponding tab is on the upper half of the crankshaft main bearing. Remove the lower half of crankshaft main bearing (15) from the main bearing cap. Mark the lower half of the crankshaft main bearing for identification.
The upper half of the main bearing has a tab. If the tab is pushed against the crankshaft, the cylinder block, the bearing, and the crankshaft can be damaged.When you remove the upper half of the bearing, always rotate the crankshaft so that the tab is the first part of the bearing to be removed.When you install the upper half of the bearing, always rotate the crankshaft so that the tab is the last part of the bearing to be installed.
The main bearing driver can be broken if the long end of the blade is used to install the bearing. Always use the short end of the blade to install the bearing.
