Porsche 914 All 1st Gear with 5-Speed
The dog teeth ring forms part of the gearbox synchroniser assembly. It works with the synchro ring, operating sleeve, and gear hub to allow the selected gear to engage smoothly. On 1st gear, the dog teeth are critical for clean gear selection, especially during low-speed driving, manoeuvring, and gearbox operation from rest.
Functions
• Replaces the 1st gear dog teeth ring
• Helps restore correct 1st gear engagement
• Works with the synchro ring and operating sleeve
• Supports smoother gear selection
• Helps reduce crunching, baulking, or poor shift feel
• Suitable for gearbox rebuilds and synchroniser repairs
• OE Match replacement for classic Porsche transmission service.
Why Replace This Part?
Dog teeth can wear, chip, round off, or become damaged through age, high mileage, poor lubrication, worn synchro parts, or aggressive gear changes. Worn 1st gear dog teeth may cause difficult gear engagement, crunching, jumping out of gear, or poor shift quality. Replacing the dog teeth during gearbox overhaul helps restore reliable synchroniser operation and smoother 1st gear selection.
When to Replace This Part
• 1st gear is difficult to select
• Crunching or baulking occurs when engaging 1st gear
• The gearbox jumps out of 1st gear
• The dog teeth are chipped, rounded, worn, or damaged
• The synchro ring or operating sleeve is being replaced
• The gearbox is being rebuilt or inspected
• Preventative replacement is being carried out during transmission overhaul
Where it fits on the car
This dog teeth ring fits inside the gearbox on the 1st gear synchroniser assembly. It forms part of the internal gear engagement system and should be installed according to the factory gearbox layout.
