I looked on line and found an exploded view of the filter. The spring drops into the housing first than a bushing then the filter is tight to the block. the exhaust is stock, I think the middle gear may be under the piece that combines two pipes into one, the "skid plate" I was referring to. The main oil plug is right under the filter housing. Is this the one you are talking about?

hey, This newbie just bought an '82 750 seca and am changing the oil and filter on it. Does the filter drop into the bottom of the housing with the flat rubber washer fashing front? (the old filter had front stamped on it, the new doesn't) This puts the spring on the motor side of the filter. Any help would be appreciated, I was too busy with twisting the hot filter housing in between the even hotter muffler pipes. Also, where is the middle gear drain plug, under the muffler skid plate? Thanks Joel
