Not to my knowledge but you can press the "cross" rearward a bit (support the shaft on the back side if you ever do this) but the limiting factor is the clearance between the pulley groove to the pump 4 bolts & you'd need a shallower pulley and a pulley with a straight barrel rather than a tapered barrell may help with the clearance inside the barrel (been a long time since I dealt with that) but I remember an issue there. Easier might be to mill the pump housing rear face to move the whole shebang rearward then reestablish pulley alignment. there is a part number for a short fan extension (jaguar?) that has been used by us. EDIT now I remember, a non tapered pulley barrel did not touch the pump body shank
