THE #1 HOLE MUST BE WELDED UP OR TAPPED AND A SCREW OR BOLT USED TO BLOCK THE HOLE. YOU MUST USE A SEALER ON THE THREADS IF USING THE TAP METHOD AND GRIND THE OUTSIDE SMOOTH TO THE BASE METAL AND IF YOU WANT, CENTER PUNCH THE THE END TO PREVENT BACKING OUT. THE HEAD MUST BE ON THE INSIDE OF THE MOUNT.
THE #2 HOLE NEEDS TO BE DRILLED TO ACCEPT A 3/8 NPT BUSHING TO A 1/4 NPT. YOU CAN USE A 1/4 HERE BUT I USED THE LARGER INCASE I NEED TO CHANGE THE HOSE ADAPTER AND THE THREADS GET MESSED UP. THE NPT IS TAPERED SO YOU ONLY WANT TO RUN THE TAP 1/3 THE WAY SO THE BUSHING CAN HAVE A NICE INTERFERENCE FIT. YOU NEED TO RUN THE BUSHING UP TIGHT WITH A BOX WRENCH.
WITH THE END OF THE BUSHING STICKING TO THE OUTSIDE, PLACE THE FILTER OVER THE THE BUSHING, MAKING SURE THE BUSHING IS AGAINST THE INSIDE RIDGE OF THE FILTER NEXT TO THE O-RING. NOW DRAW A CIRCLE AROUND THE OUTSIDE OF THE FILTER. TAKE A RULE AND PLACE AT ONE END OF THE DRAWN RING AND ROTATE RULE TILL YOU GET THE HIGHEST READING ON THE OTHER END AND DRAW A LINE. YOU MUST DO THIS SEVERAL MORE TIME. THE PLACE WHERE THEY INTERSECT IN THE MIDDLE IS THE CENTER OF THE CIRCLE. NOW YOU MUST DRILL AND TAP THE HOLE FOR A 3/4" BY 16 TPI BOLT. THE BUSHING CAN BE GROUND DOWN FLUSH WITH THE BASE METAL AND SNUGGED UP AGAIN AFTER THE HEAT FROM GRINGING ENDS, POINT BEING THE BUSHING MUST NOT INTERFERE WITH FILTER.
THE BOLT NEEDS TO BE DRILL THROUGH THE CENTER FOR A 1/4" NPT HOLE. TAP THE HEAD END ABOUT 1/2 TO 3/4 DEEP. THE BOLT THREADS FROM THE INSIDE USING A THREAD SEALANT AND A COPPER WASHER UNDER THE HEAD. IF YOU CAN NOT FIND A WASHER, MAKE SEVERAL PASSES OF TEFLON TAPE UNDER THE HEAD AND WRENCH IN TIGHTLY.
THE FILTER TO USE IS A WALMART SUPERTECH ST4967 OR ST 4386. THE PUROLATOR PL14476 OR PL1447; MOBIL1 M1-102; BOSCH 3330; AMSOIL 133, 134, 135; BALDWIN B33, B37; FRAM PH4967; HASTINGS LF410, LF413; NAPA 1394; PUROLATOR ML16822; OR THE WIX 51395, 51396 AS OTHER OPTIONS. THESE FILTER RUN 3" TO 3.5" LONG AND HAVE AN 8 PSI BY-PASS VALVE.
THE INLET TO THE FILTER FROM SCAVENGE SIDE (RETURN TO TANK) OF PUMP GOES TO THE BUSHING OR OUTSIDE OF FILTER ( RING WITH MULTI-HOLES) CENTER HOLE. THE RETURN TO THE TANK COMES FROM THE CENTER HOLE OF THE FILTER. IF YOU USE A COOLER, THIS CENTER CONNECTION WILL GO TO THE COOLER AND OUTLET OF COOLER TO TANK.
THE TOTAL INVESTMENT WAS ABOUT 20 BUCKS, NOT INCLUDING THE FILTER, JUST BARB CONNECTIONS AND SUCH. THIS CAN BE DONE ON THE MACHINE ALTHOUGH IT IS EASIER DOING ON THE BENCH.
