New High Strength Alloy, Heat Treated iron based valve guides are installed. These guides are heat treated to Rockwell 22 “C” Scale, which produces the ultimate in wear resistance. This is far superior to original guide material, including Bronze. The guide incorporates a spiral grove inside the guide to hold oil and aid the lubrication of the valve during engine operation. Guides are then honed (not reamed) to exact size using a diamond honing mandrel. Diamond abrasives allow for consistency of size, surface finish, and bore geometry with no variation from guide to guide. The guide size is then verified using a valve guide bore gauge. As needed the head receives new Premium valve seat inserts made from a true Nickel Based Non-Magnetic material that was developed for extreme operating conditions.
Next the head is treated to a multi angle valve job to help maximize the flow of air in and out of the head. This is accomplished using a Serdi 100 guide and seat machine. Serdi uses a solid carbide straight shank pilot. When inserted into the valve guide, it simulates the real valve stem during the centering process. This guarantees the valve seat is finished for a perfect valve to seat match. Using CBN or Diamond tooling the head is given a new surface. With our berco milling machine we can control the surface finish to accommodate different head gasket types. For example MLS head gaskets require a very smooth surface finish. Finally the head is jet washed dried and assembled with new valve seals and new valve springs.
.Industrial Injection® is a family operated business, founded by the owner Brady Williams in 1985. Brady’s initial start in fuel injection was with a local shop, mopping floors after school. By 25, Brady was a master technician at Association of Diesel Specialists for all manufactures of turbochargers and fuel equipment. With hard work, sacrifice and a little help from fate, 30-year-old Brady opened Industrial Injection. Industrial Injection received its name from servicing construction, agricultural, and mining equipment, as well as, over the road truck engines. It was primarily an agricultural and industrial fuel shop. Industrial Injection has always had an interest in helping farmers, truckers and miners with horse power gains, fuel economy and reduced emissions.
