For further strengthening of the oil pan you may elect add the plates to all pan mounting locations.2. Before cutting the side plates make sure that the recommended dimensions for the side plates will cover the entire length of all cracks by at least 20 mm. This may require modification to the dimensions in Figures 2,3 and 4, depending on the length and location of the cracks. Remember that round or oval shaped ends of the side plates need to be maintained. Any sharp corners will provide stress risers for new cracks to start.3. Cut all side plates required to update the oil pan.4. Prepare each weld area by making sure all surfaces are smooth after weld repair. This includes placing plates over weld area to verify that the plate rests flush with existing side wall. If bevel edge interferes with existing mounting boss weld, then grind back bevel edge to allow for plate to rest flush with existing side wall.5. Clean entire length of ground area:a. Before any welding is started on the oil pan make sure the area to be repaired is thoroughly cleaned. Use a wire brush or grinding stone to clean the enough area to weld to bare base material.b. All oil, grease, paint, etc. must be cleaned from the joint surfaces and enough area to weld to bare base material. Surface oxides must be removed from the area to be welded.c. Good cleaning and surface preparation of the area to be welded is very important, if a good quality repair is to be made.6. Using 1U(5232 welding electrode (3.0 mm, E 7018) tack weld along outer edge of plate at 90 degree locations using following sequence: top, bottom, right , left.7. Using 1U(5232 welding electrode (3.0 mm, E 7018) to complete groove weld, fill in V shaped area, between plate and existing mounting boss weld. This may be a relatively large area, which may require multiple passes. Please make sure following temperature guidelines are not exceeded at all times.* Do not let temperature exceed 260° C.* Make sure welding surface temperature is above 16° C. 8. Using 1U(5232 welding electrode (3.0 mm, E7018) weld around entire outer edge of plate. This should be accomplished with a single pass weld with 3 mm fillet size.* Do not let temperature exceed 260° C. * Make sure welding surface temperature is above 16° C.
