To remove the engine from the vehicle, first take out the oil pan fasteners and detach the oil pan from the engine, using a Tor bit for the bolts on each side of the crankshaft rear oil seal and a Tone driver for the two adjacent bolts. If needed, remove the baffle fasteners to take out the baffle, which is secured to the main bearing caps. For installation, be cautious as two oil pan bolts are attached to the transmission, requiring the correct selection of spacers to prevent damage or leaks. Clean all old gasket material from the oil pan and its mounting surface with a gasket scraper, and remove any residue with a solvent. Position the oil pan on the engine block, then use a straightedge across the transmission mounting surface and one of the oil pan-to-transmission bolt mounting pads to measure the gap with a feeler gauge. Repeat this for the other mounting pad and select spacers to compensate for the gap, available in three thicknesses. Apply a thin bead of ATV sealant to the outside edge of the gasket surface and around the crankshaft rear oil seal at the rear of the engine, as well as to the seams and corners of the front seal cover and engine block-to-timing-chain cover. Install a new oil pan gasket, secure the oil pan fasteners evenly to the specified torque, and ensure the long screw next to the crankshaft rear oil seal is properly positioned. Finally, install the spacers on the mounting pads before bolting the engine to the transmission.
