What are the torque specs for the connecting rods?
| Connecting Rod Bolt Specification | Steel Connecting Rods | |
|---|---|---|
| Part # | Dia. x U.H.Length | Torque |
| 90803 | 7/16″ x 1.940″ | 65 ft lbs |
| 90804 | 7/16″ x 2.320″ | 65 ft lbs |
| 90805 | 3/8″ x 1.920″ | 50 ft lbs |
What bearing is fitted in the connecting rod big end?
Main bearings of such type are called flange main bearings. Connecting rod bearings provide rotating motion of the crank pin within the connecting rod, which transmits cycling loads applied to the piston. Connecting rod bearings are mounted in the Big end of the connecting rod.
What is torque rod?
Torque rods are suspension links that are meant to limit the movement of the axles without limiting suspension articulation. Torque arm suspensions are very common on medium and heavy-duty trucks and trailers. Torque rods can be longitudinal (running forward and aft), or they can be transverse (running side to side).
What type of bearing is used for connecting rod bearing?
Plain bearings are used in main bearings and connecting rod bearing. Its main application is in the piston and connecting rod in engine.
What are connecting rod bolts?
Connecting rod bottom end bolts keep the two halves of the bottom end bearing together. These bolts are subjected to complex nature of stress as follows: Tensile Stress: Tightening of nuts stretches the bolts and subjects them to tensile stress, which helps keep the two components together under tension compression.
What is Torque rod?
When checking your torque rod make sure it is?
When performing these inspections, check the following:
- Inspect torque rod fasteners and torque rod bracket fasteners to ensure they are tightened to specification.
- Visually inspect the torque rods for bends, cracks, or other damage.
- Inspect the bushing looking for worn, torn, cut or walked out bushings.
What holds piston to connecting rod?
The piston is attached to the connecting rod by a short hollow tube called a wrist pin , or gudgeon pin . This wrist pin carries the full force of combustion. The piston is not only subject to vertical forces during combustion, but also side forces caused by the continuously changing angle of the connecting rod.
Which material is used for connecting rod?
The materials used for connecting rods widely vary, including carbon steel, iron base sintered metal, micro-alloyed steel, spheroidized graphite cast iron. In mass-produced automotive engines, the connecting rods are most usually made of steel.
