Why are cap style bolts used on performance rod?
To save weight, many performance rod designs are drilled so cap style bolts can be screwed directly into the body of the rod, eliminating the need for nuts on the bolts. This saves weight, allows more clearance for a stroker crank and usually does a better job of holding the rod cap tightly against the rod.
What causes a connecting rod to lose lubrication?
Loss of lubrication may also be from using a thin oil that lacks the shear strength to stay between the rod bearings and crank journal. Using an oil that has too low a viscosity for loose bearing clearances can do the same thing.
Is it possible for a connecting rod to fail?
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. Connecting rods are some of the hardest working parts inside an engine.
What do the connecting rods on an engine do?
The rods also tie the pistons to the crank so the pistons can reciprocate and complete their intake, compression, power and exhaust strokes. In this role, the rods have to resist stretching forces that wants to pull them apart at high engine speeds.
How to replace control arms, end links, and ball rods?
Take an 18mm socket, with an 18mm wrench to counter hold, and remove the bolt holding the control arm into the subframe. The axle may be in the way when trying to pull the bolt out. Put some wood on your jack and jack up the knuckle by the brake disc.
