How to test a torque converter without uninstalling it?
Remember to not release the brake pedal. With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.
Can a stall speed test be done on a torque converter?
Torque converter issues on a lot of older transmissions can be diagnosed by carrying out a stall-speed test. Below we have outlined how you can safely and easily conduct a torque converter test.
What are the torque specs on a Suzuki?
Item N*m kg-m lb-ft Starter clutch bolt 10 1.0 7.0 Generator stator set bolt 10 1.0 7.0 Generator stator clamp bolt 5.5 0.55 4.0 Crankshaft position sensor set bolt 5.5 0.55 4.0
What causes an out of balance torque converter to stall?
Since everything from the turbine back is held stationary, an out-of-balance driveshaft or tire would not appear during a stall test. An out of balance driveshaft causes a vibration that increases with vehicle speed, not while it sits stationary.
Is it normal to have one way stator clutch?
A little blue discoloration around the hub is considered normal, but dark blue/black is not. To diagnose the one-way clutch, place the torque converter on the bench, and use your fingers to rotate the stator inside of the shell. It’s splined and should spin freely in one direction and lock in the other.
Where is the stator clutch in a torque converter?
Torque Converter Stator The stator clutch is located inside the vehicle’s torque converter. It’s critical to the operation of the torque converter and the overall drivability of the vehicle. During low-speed operation, the stator locks, creating a vortex.
Why is there no torque multiplication with overrunning clutch?
At this point, there is no more torque multiplication because the stator is allowed to spin freely. The stator’s overrunning clutch enables the stator to spin freely in one direction but keeps it from rotating in the other.
What happens when one way stator is bad?
An overrunning clutch allows the stator to spin freely in one direction and keeps it from rotating in the other. If the stator’s one way clutch is faulty and allows the stator to spin freely while at low speeds, there will be a loss of torque multiplication, resulting in poor low speed performance.
Why does a torque converter make a car less efficient?
Because of the no direct connection between the engine and the transmission, you are losing some power from the engine and the engine will become less efficient. This is often why older transmissions are having a higher fuel consumption than a manual gearbox car.
How long does it take to stall a torque converter?
With one foot on the brake pedal, press the accelerator all the way for 2-3 seconds with the other foot. Be careful not the exceed 5 seconds or the transmission could blow out.The stall speed is the RPM the engine maxes out at.
What to do if your torque converter is slipping?
If you are experiencing a slipping torque converter and you have replaced the transmission fluid and filter and even done a transmission flush to it, it’s time to remove the transmission from the engine and inspect the seals on the axle into the transmission. Here is a video of how to replace the seals inside a transmission.
