The clutch Release Bearing is often called the throwout bearing and is operated by the clutch Release Lever.

The bearing was originally designed for the Datsun 510 model series (part code 210), so fits many Datsuns, basically most RWD model with A-series, L-series, Z-series, KA-series or VG-series engines.

Bearing Sleeve
Datsun 1200 release bearing sleeve/carriers
- 30501-H1000 SLEEVE-BEARING CLUTCH RELEASE B110 ex. 5-speed, B120 LB, B120 SB -7308
- 30501-H5000 SLEEVE-CLUTCH RELEASE B110 5-speed, B120 SB 7309-
For A-series engines, there are two lengths. One is 4.5 mm longer.
Discussion: Clutch Problems
When swapping transmissions and engines, you should get them as a complete set:
- Engine plate
- Transmission
- Release lever
- Release bearing carrier
If you don't use a matching set, and after swapping transmissions you find the clutch doesn't engage correctly you may need to use the shorter Sleeve, or make your own longer sleeve.
Datsun Sleeve ID:
Differences
What determines whether you need to use the short or long bearing carrier? It seems the diff and propeller shaft would have no effect on this. The dimension difference is beween the engine and transmission case and what's in between:
- Engine block rear face/crankshaft spec?
- Transmission front case depth?
- Clutch cover installed height? It seems not. Clutch cover installed height (diaphragm spring-to-flywheel height):
- B110: 30mm ±1 @ diameter 62mm
- B310: 30mm ±1 for all engines & transmissions
- Flywheel? Weight differs, but isn't the face depth the same A12/A14/A15? All B110 uses same flywheel, yet the GX-5 uses a different release bearing carrier sleeve. Likewise, all B120 utes use the same flywheel, yet SB uses one carrier and LB the other.
- Clutch fork (release arm)? All 56-series B110/B210/B310 are the same. 60-series differs.
- Engine plate (or lack thereof)? 30411 Rear Engine Plate
B110 uses no engine plate, only a dust cover as on the right:
Left: 5mm thick engine plate, used by B210 and later B120 (Datsun 1200 truck)
B110: is the transmission front case dimension different?
- B110 no plate, 3/4spd - carrier H1000
- B110 plate, 5-speed - carrier H5000
B120: Transmission front case differs, but how?
- B120 no plate, Long Body - carrier H1000
- B120 plate, Short Body - carrier H5000
B210, flywheels are different with the different transmissions, but does that matter?
- B210 plate, 60-series - carrier H1000
- B210 plate, 56-series - carrier H5000
Is there one simple difference which determines the carrier length? Or a combination of factors?
"[60-series 5-speed]: the ball the fork runs on is 3.5mm further back from the bellhousing face than it is on my 56 series"
