Is the pipe that runs threw the flange bearings on the fan stand solid or hollow and how do you mount the fan shroud when you have a reduction, do i have to take the reduction off put the shroud on then put the reduction back on? Any help would be appreciated or pictures
Yeah I would use 1 1/4'' solid rod. The shroud should be installed behind the reduction. Remove reduction, slide on shroud, replace reduction. The fan shroud will mount the same with or without the ruduction. You will have to design the shroud to have a mounting plate in the center of the shroud that will attach to the engine block.
