Preventing Connecting Rod Failures
Connecting rods are some of the hardest working parts inside an engine. Fortunately, rod failures from severe overloading don’t happen that often. However, they can occur in racing or extreme street performance applications. So here’s what you need to know.
CP-Carrillo 4.6 Ford Modular Bullet Rods
CP-Carrillo has introduced 4.6 Ford Modular Bullet rods. These connecting rods include the advanced features and improvements that CP-Carrillo has developed through rigorous testing and R&D.
Internal Affairs – Diesel Crankshafts and Rods
Despite having similar appearances, a diesel crankshaft has some primary differences from its gasoline counterparts. A gasoline engine uses a spark to ignite the fuel. A diesel engine, operating at a much higher compression ratio, uses the heat produced by compression to ignite the fuel. Diesel engines typically have a longer stroke than the bore diameter, so to handle this load, diesel crankshafts are much larger physically.
Connecting Rod Installation Basics
Here is some good, basic information about how to properly install connecting rods. Step 1: Apply the molybdenum base lubricant under the head of the bolt and on the threads. Step 2: With the bolts installed hand tight, install the gauge and zero the dial indicator. The stretch gauge must fit into the
Performance Diesel: The New Hot Rods
With all of the bolt-on diesel components that are available on the market these days, why would you get into offering performance engine rebuilds for the diesel market? I’m sure you are asking yourself this question every time you get a call from someone with a diesel engine asking how they can get more power. But believe
Connecting Rod Selection for Performance Engines
The types of rods are broken into four families: stock, aluminum, 4340 forged and 4340 billet. I know there are some 4130 and 5140 aftermarket rods available, but I have no experience with these. Stock rods vary from manufacturer to manufacturer, not only in size and shape, but in the amount of power and RPM’s
Diesel Connecting Rod Reconditioning
As a result, connecting rodreconditioning is a critical part of all diesel overhauls. Uponteardown, the old connecting rods are inspected, magnafluxed, checkedfor alignment, parting surfaces re-machined, and new rod bushingsinstalled and pin-fit. At the same time, the rod bolts are measured forstretch. This is all normal, day in, day out activity at any heavy duty
Racing Rotating Assemblies: Cranks, Rods and Pistons
Building a performance engine requires assembling the optimum mix of rotating components that are compatible with the block and heads, properly matched with each other, and balanced to precise tolerances. The easiest way to get the right combination of parts is to buy a complete rotating assembly from a supplier who offers such kits. Most
Selecting Cranks, Rods and Bearings For Your Next Build
Racing engines are made for one thing – speed. But speed is a wide target. It is in the sum of parts that are bolted together to make up the package that speed is delivered to your customer. Engine builders know that one of the biggest areas where races are won and lost is in
Understanding Oval Track Cranks & Rods: There’s more to it than you think
Racing’s racing, right? The first one is the winner and second place is just the first loser. While that may be true as far as it goes, getting across the finish line first takes different techniques depending on the type of racing it is. Racing engines are not immune to specialization. Where one style of
Connecting Rod Reconditioning: More to it than you might think
The connecting rod plays a vital role in the engine. But a connecting rod is under tremendous stress, with the weight of the piston sitting on top, changing direction thousands of times per minute. This continuous stopping and changing of direction combined with the weight of the piston and speed of the engine hammer on
Connecting rod bolt torque specifications used in various Allis Chalmers agricultural or industrial engines
Engine Builders: In an effort to clarify the confusion about connecting rod bolt torque specifications used in various Allis Chalmers agricultural or industrial engines, the AERA Technical Committee offers the following information. This information applies to both early and late style engines, as several different hardware combinations have been used in the 201, 301 and

Many times, the flange diameter of the rod nuts will contact the radius around the nut seat on some rods. Some jobs may not warrant the expense of spot facing the nut seat on the connecting rods. In that case, it can be quicker and more effective to just machine a chamfer on the ARP rod nuts.
