Operating clearance of the clutch is typically measured at the clutch release fork or the clutch pedal. It is the distance between the clutch release bearing and the pressure plate when the pedal is fully released. This measurement ensures that there is enough clearance for the clutch to engage and disengage properly without causing excessive wear or slippage. Proper adjustment of this clearance is crucial for optimal clutch performance.
The TH400 (Turbo Hydramatic 400) transmission typically requires a forward clutch pack clearance of around 0.030 to 0.060 inches and a direct clutch pack clearance of approximately 0.040 to 0.060 inches. These clearances are essential for optimal performance and to ensure proper engagement and release of the clutches. It's crucial to measure and adjust these clearances accurately during transmission rebuilds or servicing to prevent issues like slipping or harsh shifting. Always refer to specific service manuals for precise specifications based on your application.

clucthes no, bands yes ---------- Addition to above: Clutch pack clearance can be adjusted by using different thickness of steel plates, they are available in .077 and .090 and there are some made of heat treated kolene steel available in .060 thickness, you can mix different thickness steel plates to achieve the desired clearance -- usually about .008 to .010 PER CLUTCH, which means in a clutch pack with 5 clutches you multiply 5 times 8 and get ,040" for your minimum and 5 times 10 and get .050" for maximum, this isn't rocket science and if you were shooting for the middle at .045 and juggled different thickness steels and ended up with .055" clearance you'd be fine, the fiber clutches start out .080" thick and as they wear the clearance increases so .005" on the loose side wouldn't bother me a bit, running them too tight can cause them to drag and get hot so I would stay with .008 per clutch in the clutch pack as bare minimum especially in the direct clutch.
At the clutch plate and the pressure plate.
Operating clearance on a clutch can typically be measured at the clutch release mechanism, which is often located near the clutch pedal or the bell housing. It is the distance between the clutch release bearing and the pressure plate when the clutch is disengaged. This measurement ensures proper engagement and disengagement of the clutch, preventing issues like slippage or difficulty in shifting gears. Always refer to the manufacturer's specifications for the correct clearance values.
in order to prevent continuous rotation of the release bearing. This prevents premature wear of the bearing. To ensure that the full spring pressure and clamping force is applied at the clutch contact faces. This prevents clutch slip.
The clutch is non-adjustable. It uses hydraulic fluid to release the clutch. If you are experiencing a dragging clutch, check your plates for warpage. This bike uses a 'slipper' type clutch so having the correct plates in certain places is important. If you have not changed your plates and they are the originals, check that the clutch fluid doesnt have air in it.
Insufficient clutch pedal clearance can lead to incomplete disengagement of the clutch, causing difficulty in shifting gears and potential grinding noises. This condition may also cause premature wear of the clutch components, overheating, and increased stress on the clutch release mechanism. Ultimately, it can result in diminished vehicle performance and may require costly repairs if not addressed promptly.
a direct shift is a type of dule gear box, by having 2 clutches faster gear change is possible. The outer clutch pack drives gears 1, 3, and 5 (and reverse). The inner clutch pack drives gears 2, 4, and 6. Instead of a standard large dry clutch, each clutch pack is a collection of four small wet interleaved clutch plates.
The pressure plate is not fully releasing (clutch pack is bad)
If there were no operating clearance the clutch release bearing would constantly be in contact with the spring diaphragm causing wear on both the diaphragm and the bearing itself, also the bearing pushing on the diaphragm could cause the clutch friction plate to not be fully engaged and slip.
