  1. ESTA ES LA PALABRA DE FE QUE PREDICO: QUE SÍ CONFIESAS CON TU BOCA QUE JESÚS ES ÉL SEÑOR Y CREES EN TU CORAZÓN QUE DIOS LE LEVANTÓ DE LOS MUERTOS SERÁS SALVO PORQUE CON EL CORAZÓN SÉ CREE PARA JUSTICIA Y CON LA BOCA SE CONFIESA PARA SALVACIÓN

  2. What a complete waste of time , this is an item that cannot be repaired, it can o ly be machined to accept bigger main bearings and big end bearings , how you guys break so many crankshaft, steering rods , axles just shows the stuff is crap to start with , at least you may get some money from utube for entertainment purposes only , your customer has just wasted any money they paid you as this will not work end if story , put the scrap towards another new toffee crankshaft

  3. As a time-served 6 years Fabrication Plater /welder your major mistake was to drill and tap for the three studs it took away any strength in the new joint. after a Brinel test you should have clamped the break together and supported the whole crankshaft along its length braced with angle Iron. Set it up in the lathe and ensure correct allignment ground out the V for the welding and put in a root weld Using low hydrogen rods 10swg the whole of the break should have been welded with low hydrogen rods after heating in an oven. Your welding set was crummy it should have been a DC set. After welding the crank then needed heat treatment to stress relieve it check again for alignment if it was out of alignment heat the angle iron bracing and the crank to expand or shrink the crank to align it, Harden and temper the crank to suit the spec Do another Brinel test before a regrind. I have repaired many crankshafts for classic British motorcycles broken /worn out big ends built up / knackered splines / resized for metric mains triples twins singles new threads Sq 4s…. There is a limit with the cast iron flywheels and where the break is especially small bearing crankshafts.
