Make a bearing puller. Thats what i did. Take a pipe thats id is the bearings od. Now cut it about 4 to 5 inches. Then cut it in half so u hav 2 half circles. . If u know what i mean. . .now get a flat square metal plate about a quater inch thick and size of the bearings diameter by the bearings diameter. Im nt sure what size the bearing is but u gana hav a flat plate with 2 half circle pipes welded on it. Itl be a pipe again but hav cuts 180 degrees from eachother. So u can flex open and close the thing to fit over the bearing. Now if u slip it ova the bearing, the part that touches the crank web, u should tac weld it and grind it down so when u tighten it over the bearing there will be small bumps going in behind the bearing to grip it. Ok when thats done u must dril a hole in the midle of the plate. Any size. What u gana be doing is u gana weld a nut over the hole and a bolt with a sharpend point is gana screw in. So now u jst pop it over the bearing, tighten it with a hose clamp. And screw the bolt in making sure it hits the midle of the crank shaft. Then it comes off. . .hope i explaind proply. . .
