Synchro ring 1st/2nd gear. Porsche 911 Turbo 1975-88 (4 speed gearbox)

93030230110

Product Information

Genuine Porsche synchroniser ring for first and second gears in the Porsche 911 Turbo (930) four-speed gearbox, covering the supplied 1975–1988 application.

Fits:
Porsche 911 Turbo 1975 - 1988 (4 speed gearbox)

Diagram ref no: 41

What This Product Does

The synchro ring works within the gearbox synchroniser assembly to bring rotating components towards matching speeds before the selected gear engages. This product is the ring for first or second gear, not a brake band or dog-tooth component.

Functions

Provides friction for synchronising gear speeds during selection.
Supports engagement of first or second gear within the specified transmission.

Technical Details

Brand: Genuine Porsche.
Gear application: 1st/2nd gear.
Transmission application: four-speed manual gearbox.
Existing product reference: 93030230100.

Symptoms of Fault

Crunching or grinding while selecting first or second gear.
Resistance to engagement or a need to pause before completing a shift.
Gear clash during downshifts.

These symptoms do not confirm ring wear on their own. Clutch operation, linkage condition and gearbox oil can also affect selection.

Why Replacement Matters

A worn friction surface can prevent the synchroniser assembly from matching speeds effectively. Renewing a ring after confirmed wear addresses that component during gearbox repair. Inspect the associated engagement teeth, brake bands and selector components rather than assuming the ring is the only worn part.

FAQs

Will fresh gearbox oil repair a worn ring?
No. Correctly specified oil may influence shift feel, but it cannot restore a worn friction surface.

Does double-declutching fix the problem?
It may ease the symptoms, but it does not renew damaged synchroniser components.

Which reference should I check?
Confirm the recorded part number and the relevant gearbox illustration before ordering, as the supplied product and internal diagram references differ.

Porsche 924 Carrera GT 1981
Porsche 924 Turbo 1979-84
Diagram ref no 23
Transmission bearings support rotating shafts and gear clusters under high loads and speeds. Over time wear, misalignment or contamination in the gearbox can cause bearing failure, leading to increased friction, vibration, noise or even gearbox damage. Correct bearing fit is essential for longevity and precision of the transmission.
When to replace:
• During any gearbox overhaul or rebuild, especially when shafts or collar nuts are removed.
• If you notice unusual gearbox noises (rumbling, growling) or shaft play during inspection.
• Whenever replacing major gearbox components—such as synchros, shafts, or other bearings—as a preventive maintenance measure, ensuring optimal alignment and performance.

Synchro ring, 1st / 2nd gear. Porsche 911 Turbo (930) 1975-88 (4-speed gearbox)

93030230110/1

Product Information

Synchro ring, 1st / 2nd gear
OE Match synchroniser ring for first and second gear in the Porsche 911 Turbo (930), covering 1975–1988 vehicles with a four-speed gearbox. It is a replacement component for worn synchroniser assemblies during transmission repair or rebuilding.

Fits:
Porsche 911 Turbo 1975 - 1988 (4 speed gearbox)
Diagram ref no 41

What This Product Does

The synchroniser ring provides friction within the synchronising mechanism to help bring rotating components to matching speeds before a gear engages. Its role concerns gear synchronisation rather than replacing the separate brake bands, engagement teeth or shifting sleeve.

Functions

Helps synchronise rotational speeds during first- or second-gear selection.
Forms part of the gearbox synchroniser assembly.

Technical Details

Gear application: 1st / 2nd gear.
Transmission application: four-speed gearbox.
Supplied product reference: 93030230100.

Symptoms of Fault

Crunching or grinding during first- or second-gear selection.
Resistance to engagement or a need to pause between shifts.
Gear clash when changing down.

These symptoms are not conclusive evidence of ring wear. Clutch operation, linkage condition and gearbox oil can also affect selection.

Why Replacement Matters

A worn friction surface can compromise synchronisation. Renewing the affected ring addresses this wear during a diagnosed gearbox repair. Inspect the associated engagement teeth, brake bands and shifting components at the same time, rather than assuming the ring alone accounts for every shifting problem.

FAQs

Can different gearbox oil repair a worn ring?
Correctly specified oil may influence shift feel, but it cannot renew worn synchroniser surfaces.

Does double-declutching resolve the fault?
It may make engagement easier, but it does not repair the underlying wear.

What should be checked before replacement?
Confirm the gearbox specification and assess the clutch, linkage and related synchroniser components.
