The gearbox ground strap completes the electrical circuit between the transmission and chassis. A secure ground connection is essential for starter motor performance, charging system function, ignition reliability, lighting, and general electrical stability.
Functions
• Connects the gearbox/transmission to the chassis ground point
• Provides a reliable earth path for the drivetrain
• Supports correct starter motor operation
• Helps maintain stable voltage across the electrical system
• Reduces the risk of intermittent electrical faults
• Helps prevent poor grounding issues during starting and charging
• OE Match replacement for the original gearbox earth strap
Ground straps are exposed to moisture, road dirt, corrosion, vibration, and age-related wear. Over time, the strap can fray, corrode, loosen, or develop high resistance, which may lead to slow cranking, starting problems, charging issues, flickering lights, or unpredictable electrical faults. Replacing the gearbox ground strap helps restore a strong electrical connection and improves overall reliability.
When to replace
• The original ground strap is corroded, frayed, cracked, or damaged
• The gearbox or transmission has been removed or refitted
• The car has slow cranking or intermittent starting issues
• Electrical faults appear after drivetrain or starter work
• Lights, gauges, or ignition systems behave erratically
• The ground strap connection is loose or heavily oxidised
• The vehicle is undergoing restoration or electrical system repair

A rubber shaft oil seal (radial seal) for the main/input shaft of a 901/915-series gearbox. It fits around the rotating shaft and seals the interface between the rotating shaft and the gearbox housing to prevent gearbox oil leaks.
Dimensions: 23 mm (shaft diameter) × 35 mm (outer diameter) × 8/11 mm thickness (seal housing/dual-lip design).
Fits:
Porsche 911 1972 - 1973 (TYP 915) from:
G 733 7575 >>
G 723 0507 >>
G 783 0838 >>

This seal prevents gearbox oil from escaping around the input or main shaft, ensuring the transmission remains properly lubricated. It also blocks dirt, water, and other contaminants from entering the gearbox, helping preserve internal components and maintain correct operating pressure. By replacing a worn, hardened, or cracked original seal, it restores a clean, leak-tight barrier for reliable long-term gearbox performance.
Original gearbox seals degrade over time: rubber lips harden or crack, springs lose tension, and sealing surfaces wear. A failing main-shaft seal typically leads to:
• Gearbox oil leaks
• Loss of gearbox oil over time (low oil level)
• Contamination ingress (dirt, water), leading to accelerated gearbox wear or internal damage
• Messy drip underneath the car and gearbox housing
Replacing the seal with a correct-spec new unit restores proper sealing, preserves gearbox oil integrity, and helps prevent costly internal damage or gearbox failure.
You should replace this seal if:
• Gearbox oil leaks are visible around the input shaft or bellhousing area
• There is seepage, oil dripping, or a film of oil on the underside of gearbox or clutch area
• The old seal appears cracked, hardened, or visibly damaged
• You are doing a gearbox rebuild, overhaul or maintenance
• You notice loss of gearbox oil or suspect contamination ingress

OEMatch Gearbox Casing / Casing Parts — Engagement, Smoothness, Control
OEMatch gearbox casings and casing parts for Porsche models provide the structural housing and sealing surfaces that support gears, shafts and bearings. These items are specified for correct alignment, oil containment and thermal stability to help maintain transmission operation across road and competition use.
Available Types
- Full gearbox casings in aluminium and magnesium
- Case covers and extension housings
- Sealing surfaces, gaskets and oil seals
Understanding OEMatch Gearbox Casing / Casing Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gearbox casings and casing parts. OE (Original Equipment) refers to parts matching original specifications for the gearbox casings and casing parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gearbox casings and casing parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch also catalogues over 4,000 part numbers and more than 8,700 OE cross-references to support repairs across Porsche generations. The casing itself is the structural foundation of a Porsche transmission: it locates bearings and shafts, supports gearsets, retains lubricant and helps control operating temperature.
Benefits Include
- Structural support and precise alignment of internal gearbox components
- Reliable sealing to prevent oil loss and contamination
- Improved heat dissipation and resistance to distortion
Why Gearbox Casing / Casing Parts Wear and Fail
- Cracks or fractures from impact, fatigue or over-torqued fasteners
- Corrosion or oxidation, particularly with older magnesium parts
- Warping or distortion due to overheating or thermal cycling
- Damaged sealing faces or degraded gaskets leading to leaks
The Importance of Replacing with OEMatch Gearbox Casing / Casing Parts
Replacing a damaged or worn gearbox casing restores structural integrity, corrects alignment and prevents oil leaks that would otherwise accelerate wear on gears and bearings. For Porsche transmissions, correct mating surfaces and sealing are essential to maintain lubrication, reduce vibration and preserve gear engagement. During rebuilds or when repairing impact damage, a suitable replacement casing helps retain original clearances and supports long-term drivetrain function.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Manufactured from materials and processes suited to transmission loads and thermal demands
- Coverage that includes classic and later Porsche models to support rebuilds and repairs
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. Check alignment and sealing surfaces during assembly and confirm correct oil type and level after refit. If you are unsure about specific assembly steps, seek professional installation.
