REMOVAL & INSTALLATION
In order to replace the rear main oil seal, the rear main bearing cap must be removed. Removal of the rear main bearing cap requires the use of a special rear main bearing cap puller. Also, the oil seal is installed with a special crankshaft rear oil seal drift. Unless these or similar tools are available to you, it is recommended that the oil seal be replaced by a Nissan/Datsun service center or an independent shop that has the proper equipment.
