What This Product Does
The synchroniser ring uses friction to bring rotating gearbox components to matching speeds before engagement. It forms part of the first- and second-gear synchronising mechanism; it is not a complete synchroniser assembly, guide sleeve or replacement gear.

Functions

• Helps equalise rotational speeds during gear selection.
• Provides friction within the synchronising mechanism.
• Supports engagement of first and second gears.

Technical Details

• Part reference: 95030431130.
• Brand: OE Match.
• Application: first and second gears, manual transmission.
• Specified gearbox: G50.10.
• The supplied assembly diagram records two rings for this application; this is not a two-piece set.

Symptoms of Fault

• Crunching or grinding as the affected gear is selected.
• Resistance at the gear lever or a pause needed before engagement.
• Gear clash during downshifts.
• Selection difficulties that are more noticeable with a cold gearbox.

These symptoms do not establish that the ring is faulty. Clutch drag, unsuitable lubricant and worn selector components can produce similar behaviour, so diagnosis should precede dismantling or replacement.

Why Replacement Matters
Renewal is appropriate when inspection confirms wear or damage affecting synchronisation. During a gearbox repair, inspect the mating engagement teeth, sleeve and related components rather than assuming that a new ring alone will resolve every selection problem. OE Match focuses on Porsche replacement applications; the exact transmission specification remains essential when choosing internal parts.

FAQs

Can different gearbox oil repair a worn ring?
The specified lubricant matters, but an oil change cannot replace worn friction surfaces or repair damaged engagement teeth.

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

What else should be checked during the repair?
Inspect associated synchroniser parts, clutch operation and selector linkage, and assess seals and bearings while the gearbox is dismantled.
