These changes include a single tap process for through holes, same tap drill size as L6 pins, a hook angle under the shoulder with matching spotface, ability to be used in thinner sections and a large increase in strength and seal. Many improvements, including one of the original design features, have been included in this new version. For sections starting at 0.200" in thickness, use C2F pins and for sections 0.750" to 2" use C3 pins.Ĭ2 was the first CASTMASTER® pin introduced and is now is being replaced with C2F pins. For repairs in thin sections down to 0.100" use C1 pins. You should always choose the largest diameter CASTMASTER® pins that you can.
Castmaster series#
Cracks that originate from the corner of the cap fit in a main bearing can be repaired with C Series pins. Cracks that extend from threaded holes, freeze plug holes, pipe plug holes and main bearing holes require CASTMASTER® pins. C Series pins will seal on both ends.Ĭracks that run crosswise on the top of cylinder heads are usually repaired with CASTMASTER® pins in order to add strength instead of spreading pressure, so the repair will not open when the head is torqued to the block. Cracks that extend back into a port are repaired by drilling through both walls.
A new seat can be ground or three-angle cut right on C Series or L Series pins. C Series pins can be used from the bottom of the seat angle outward to the end of the crack.
Because of the spotface, installing the pins at steep angles to the surface usually doesn't leave enough material thickness for the threads.Īlmost all repairs to cylinder heads that are made below the seat angle are made with L Series pins. The reasons not to choose C Series pins for all your repairs are cost, speed and technical requirements. The spotfacing is accomplished with a special piloted tool. So why not just always use CASTMASTER® pins? The installation process requires that every drilled hole receive a recessed spotface to assure some of the shoulder of the pin remains below the surface after grinding or machining.
Castmaster crack#
