Back to Basics: Reconditioning Connecting Rods
When you’re looking at connecting rods and considering returning them to service, there are many things you must consider. They are one of the most critical pieces of the engine puzzle and under great strain when in operation, so you must pay attention to the details during the rebuilding process. There are many times when
Performance Connecting Rods
The connecting rods are a vital link between the pistons and crankshaft. They connect the reciprocal motion of the pistons to the rotational motion of the crank. The weight of the rods is important because it affects the reciprocating forces inside the engine. Lighter is usually better because less weight means faster throttle response and
Briggs & Stratton Race Engines
Briggs & Stratton may not sound much like a racing pedigree to anyone not involved in karting, but to those in the know, it’s a name that carries great power and respect. Most engine builders are probably familiar with Briggs & Stratton engines, but not in racing applications – your lawnmower or other garden equipment
Tech Notes
Engine Builders: As engine technology advances to produce more efficient engines, motor oil must continue to meet the increasing demands for lubricating these precision-made engines. Development of the next specification of gasoline-fuel (GF) motor oil began only months after the latest specification, GF-4, became available in 2004. The GF-5 motor oil specification created by the

Q: I have experienced problems with blowing oil filter seals off some 4.2L Ford engines. Any solutions? A: The AERA Technical Committee offers the following information regarding high oil pressure on 1997-2004 Ford 4.2L VIN 2 engines. This condition occurs immediately after engine front cover/oil pump replacement. In some instances, this higher than normal pressure
Line Boring Equipment: A Boring Subject?
But as the British philosopher Bertrand Russell noted, "Change is one thing; progress is another." While some might say the basic techniques for line boring main and cam bearing bores in engine blocks hasn’t changed much in 30 years others say that isn’t such a bad thing. A horizontal boring bar with cutters mounted on
Coretalk: IMCA Engine Claims Top 400 Through Late Season
A total of 402 claims were made through late September, including 149 in the Modified division, 113 in the Stock Car class and 136 in the Hobby Stocks. There were also two claims in the Sprint Car division and one each in the Northern SportMod and Jeff’s Performance Southern SportMod classes. Claims so far in
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
The Angle On Valve Seats
Valve seats seem to be a fairly simple engine component but they play a critical role in sealing compression and cooling the valves. When a seat becomes worn, it may leak compression and allow the valve to run hotter than normal. The same thing can happen if the seat is out-of-round or has lost its
Align Yourself
The crankshaft main bores are the foundation of every engine block. The alignment of the main bores is important because their position establishes the centerline of the crankshaft and how the crank aligns with the cylinders, deck surfaces and camshaft. Misalignment in the main bores can cause binding and premature main bearing wear. Misalignment occurs
Dodge City’s Finest; Harry’s Machine Works
No history of the American West would be complete without extensive recollections of Dodge City, KS. Formed as a convenient railroad stop to serve the new Atchison, Topeka and Santa Fe railroad, Dodge City offered something for everyone. That is, if your tastes ran to buffalo hunting, gambling or gunfighting. In its early days, Dodge

Old Days Are Gone; Now, Reconditioned Con Rods Must Meet Critical Specs Too much twist and bend will limit oil clearances and can cause engine damage I can remember in the old days how rods were reconditioned. We had a dry hone with limited mandrels. Rods were ground, assembled, torqued and dry-honed to final specs.
