CAP SECTION C-C the regular A-beam design. STEPPED H-BEAM ROD The narrowed H-beam allows for more weight savings for applications limited cylinder pressures STEPPED BIG END With an increased big end thickness, the big end housing becomes more rigid. STRAIGHT H-BEAM The stoutest beam configuration available. It is capable to handle the most abusive forces in an engine. TAPERED H-BEAM The strong H-beam configuration can handle extreme engine loads. The tapered beam allows for some weight saving on the reciprocation end and gives increased clearance for fully boxed pistons. 2nd groove Top groove 2nd land Pin 0.088 0.120 0.004 0.891 SUPER A-BEAM With an increased beam thickness, the Super A-beam design has a higher load capacity than .006 P.D. A This feature has the H-beam design extended around the PE-strap for increased stiffness / minimum PE distortion under inertia load. An option that is used for high engine speed applications. SUPER HONE FINISH A mirror finish with less than 4 RA on the wristpin bore TAPERED PIN END To reduce reciprocating mass or accommodate piston design, the pin end width could be tapered. A PIN END AND/OR BIG END LAPPED FINISH Instead of a standard finish, the pin end and big end thrust face are lapped to obtain a finer finish. RADIUS GROOVE This feature creates an oil reservoir within the PE ID and distributes the oil towards the areas of high contact pressure. RIBBED PIN END 0.7840 1.977 3rd groove 3.8400 2.342

A-BEAM A light weight rod design for high engine speeds and limited cylinder pressures.

U and a hole through the center of the rod we have established a reservoir that supplies oil underneath the wrist pin when the connecting rod is pulling mass down the cylinder. It is most effectual on one of the four strokes of the engine cycle and certainly contributes to the longevity. RADIUS SLOT The radius slot represents the well-known and durable standard Carrillo H-beam Rod design. I 90° CUSTOM LASER MARK/SERIALIZATION CP-Carrillo offers custom laser marking such as serialization, barcodes, text, including any TrueType font, alphanumeric serial numbers, date codes, logos, part numbers, graphics, and data matrix codes. FPO (FORCE FEED OILING) 32 R1.260 H Force Feed Oiling, or Forced Pin Oiling (FPO), does not offer forced or pressurized oiling. However, by installing a slot behind the bearing 3.18 .125

33.02 R1.300 .439 .430 ARC GROOVE The arc grooves guides oil from the 10 & 2 oil holes towards the 6 o’clock position of the PE. Since the grooves are running out before reaching the 5 & 7 o’clock position, the full bearing surface under compression load is effective. OIL RESERVOIR ON PIN END A larger “funnel” at the top oil hole gives a better chance to collect oil for the PE lubrication. It is often combined with a PE bump out. PIN END POCKET The pocket relieves peak stresses at the 6 o’clock position of the pin bore. The pocket will not always result in a reduction in weight. PIN END RADIUS All Carrillo non-bushed rods are manufactured with a 0.020” radius as a standard. This option gives the opportunity to increase the radius if required for reduced edge loading. 61.47 2.420 C C D D E E 33.34 R1.313
