Dog eeth 1st gear. Porsche 911 1974-86 (915 Gearbox)

91530224114/1

Product Information

Dog Teeth 1st Gear.
The OE Match 1st Gear Dog Teeth is a high-quality replacement gearbox component designed for Porsche manual transmissions. Manufactured to OE specifications for fit, precision and durability, this component forms a critical part of the gear engagement mechanism, allowing smooth and secure engagement of first gear during operation.

Fits:

Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
Porsche 911 1978-1983 3.0L / SC
Porsche 911 1984-1986 3.2L

Diagram Ref No 43

The dog teeth ring is fitted to the gear assembly and works in conjunction with the synchroniser hub, synchroniser ring and selector sleeve. It provides the engagement points that lock the selected gear to the transmission shaft, ensuring efficient transfer of engine power through the gearbox. Precision machining is essential for smooth shifting performance and long transmission service life.

What This Product Does:

Provides the engagement surface for first gear selection.
Works with the synchroniser assembly to enable smooth gear changes.
Locks first gear to the transmission shaft when selected.
Ensures efficient transfer of engine power through the gearbox.
Supports accurate and reliable gear engagement.
Helps minimise transmission wear during shifting.
Contributes to smooth manual gearbox operation.

Symptoms Of Wear Or Failure:

Difficulty engaging first gear.
Gear crunching or grinding during gear selection.
First gear jumping out of engagement under load.
Increased resistance when shifting into first gear.
Poor shift quality or inconsistent engagement.
Excessive transmission noise during gear changes.
Visible wear, rounding or chipping of the dog teeth during inspection.
Premature wear of related synchroniser components.

Why Replacement Matters:

Dog teeth are subjected to repeated engagement loads every time a gear is selected. Over time, the engagement surfaces can become worn, rounded or damaged, particularly in high-mileage transmissions or vehicles subjected to aggressive shifting. As wear progresses, gear engagement becomes increasingly difficult and less precise.
A worn dog teeth ring can compromise synchroniser performance and may eventually prevent proper engagement of first gear. Continued operation with worn components can accelerate wear of synchroniser hubs, selector sleeves and other transmission parts, leading to more extensive and costly gearbox repairs.
Replacing worn first gear dog teeth restores precise gear engagement, improves shift quality and helps protect the transmission from further internal wear. An OE Match replacement provides factory-style fitment, accurate machining and long-term durability, ensuring reliable gearbox operation and preserving the driving experience expected from your Porsche.

Dog Teeth 2nd Gear 911 1972-86 Symmetrical Tooth Point, 1 slot in hub (915 Trans. 1972-86)

Diagram Ref no 35.

A dog-teeth gear (or synchronizer-gear hub / 1st-2nd gear dog gear) used inside the 915 gearbox. This gear section engages with corresponding hub or clutch-dog components to allow shifting between gears - in particular 1st and/or 2nd gear depending on the configuration.

Gears inside classic 915 transmissions - especially dog / synchronizer-gears - are subject to wear over time: tooth heads can round off, suffer chip-out, or distort under load; synchronizer engagement surfaces may wear and lose precision. This can cause:
• Gear-slip or missed shifts
• Grinding or clash during shifting
• Torque transmission loss or vibration under load
• Accelerated wear of other transmission internals.
Replacing worn gears with a precisely machined, correctly hardened OE-match replacement restores gear-mesh integrity, retains gearbox performance, and helps avoid costly gearbox failure.

When to Replace.
Consider fitting this gear if:
• You hear grinding, clash, or crunching during shifting - especially into 1st or 2nd gear
• Gearbox inspection reveals worn, rounded, chipped, or damaged dog-teeth or synchronizer surfaces
• You are performing a full gearbox rebuild or overhaul
• The gearbox has high mileage or signs of internal wear
• You want to restore factory-spec shifting performance and reliability

Shifting gear. Porsche 911 72-86 915 Gearbox

91530222709/1

Product Information

The Porsche replacement product code 91530222709 is a precision-engineered component integral to the 915 manual transmission system found in Porsche 911 models from 1972 to 1986

This part is a shift sleeve, also known as a synchromesh sleeve or slider, specifically designed for the 5th gear and reverse gear operations in the 915 gearboxes. The shift sleeve facilitates the engagement and disengagement of gears by sliding along the main shaft to align with the corresponding gear teeth. It plays a crucial role in ensuring smooth and precise gear shifts, particularly when selecting 5th gear or reversing.

Typically crafted from high-strength steel alloys, the shift sleeve is designed to withstand the stresses and forces encountered during gear changes.

Fits:
Porsche 911 72-86 915 Gearbox
Manual transmission

Over time and with extensive use, the shift sleeve can experience wear and degradation, leading to various transmission-related issues:

Difficulty Engaging 5th Gear or Reverse: Excessive wear on the shift sleeve's teeth or detents can result in challenges when attempting to engage 5th gear or reverse, often requiring additional effort or multiple attempts.
Grinding Noises: Worn or damaged shift sleeves may fail to fully engage the gear, causing grinding noises during gear selection.
Slipping Gears: Improper engagement due to a faulty shift sleeve can lead to gears slipping out of engagement, posing safety risks and potential damage to the transmission.
Inconsistent Shifting Feel: A degraded shift sleeve can result in an inconsistent or "notchy" shifting experience, detracting from the smooth operation expected in Porsche vehicles.

OE Match produces products to the Original Equipment Manufacturer (OEM) standard parts, ensures the replacement component meets a stringent quality standard and guarantees proper fitment.

Professional Installation: Given the complexity of transmission systems, it's advisable to have the shift sleeve replaced by a qualified technician to ensure correct installation and to avoid potential damage to the transmission.

Inspection of Related Components: During replacement, it's prudent to inspect related components, such as the synchro rings and gear teeth, for wear or damage to prevent recurring issues.
