A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission , the torque converter connects the prime mover to the automatic gear train, which then drives the load.
The lower half of the main bearings are typically held in place by 'bearing caps' which are secured to the engine block using bolts. The basic arrangement is for each bearing cap to have two bolts, but some engines may have four or six bolts per bearing cap (often referred to as "four-bolt mains" or "six-bolt mains" engines).
Toyota sought to enhance the drivability pattern of the engine (over the 3VZ) at exactly 3000 rpm, since that was the typical engine speed for motors cruising on the highway. The result was less cylinder distortion coupled with the decreased weight of rotating assemblies, smoother operation at that engine speed, and increased engine efficiency.
Bellhousing (aka bell-housing or bell) is a colloquial term for the component that aligns and connects the transmission of a vehicle to its engine, and which covers and protects the flywheel/clutch or flexplate/torque converter. [1] It derives its name from the bell-like shape that those internal components necessitate.
Crankshafts manufactured for the 1999 model year (to the end of 4.3 L (262 cu in) production) had a pilot hole depth of 1.41 in (35.8 mm) when coupled to the LSx-based 4L60E, which had a redesigned torque converter pilot hub (which was longer and was used with a 300 mm (11.8 in) stator shaft). The torque converter pilot hub was longer than the ...
The jacking gear motor is generally designed to rotate the shaft at approximately 1/10 rpm. Most jacking gear motors are rated at 5hp. The jacking gear motor assembly applies power and torque to the reduction gear by a flexible coupling or clutch that can freely engage and disengage to the high-pressure pinion (driving gear).
In 1996, a bolt-on bell housing was phased in (along with a six-bolt tailhousing) for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications. Beginning in 1998 a new 300mm torque converter with improved higher-capacity internals, 300mm style input shaft, and 300mm style pump was also introduced on models coupled to a Gen ...
A torque tube system is a power transmission and braking technology that involves a stationary housing around the drive shaft, often used in automobiles with a front engine and rear drive. The torque tube consists of a large diameter stationary housing between the transmission and rear end that fully encloses a rotating tubular steel or small ...
