Hydraulic Master Cylinder x Pack TPT10392

Hydraulic Master Cylinder x Pack TPT10392 is a comprehensive, ready-to-install hydraulic master cylinder kit designed for Trojan couplings. The 7/8" bore master cylinder assembly delivers reliable hydraulic actuation, and the pack includes the essential components to get your system up and running with confidence. This snap-lock style unit is compliant with Australian Standard AS4177.3 (1994), ensuring safety and compatibility in Australian automotive and industrial applications.

What’s included in the pack

• 1 x TPT10391 – 3/4" Master Cylinder Assembly
• 1 x TPT10392 – 7/8" Bore Master Cylinder Assembly
• 2 x TPT1040 – Cap to Suit 3/4" Cylinder
• 2 x TPT10402 – Cap to Suit 7/8" Cylinder (fits both early and late models)
• 3 x TPT1080 – Boot to Suit 3/4" Cylinder
• 3 x TPT1081 – Boot to Suit 7/8" Cylinder
• 4 x TPT1086 – Seal Kit to Suit 3/4" Cylinder ( piston not included)

Key features that matter in real-world use

• 7/8" bore master cylinder assembly with Snap Lock design for quick, secure installation and reliable hydraulic response.
• Two 7/8" cylinder designs in circulation: early models with a plastic reservoir on a cast iron body, and late models that are fully cast alloy. This means some parts aren’t interchangeable, so verify model compatibility before spares selection.
• Clear sizing guidance: Trojan offers both 3/4" and 7/8" bore options. Always check the bore size before ordering spares to ensure you match the correct components for your system.
• Cap and boot compatibility across model years: the 7/8" Cap (TPT10402) fits both early and late 7/8" cylinders, reducing the need for multiple cap categories and simplifying maintenance.
• AS4177.3 (1994) compliance provides assurance for Australian installations, with a design focused on safe, robust hydraulic control in demanding environments.

Why this pack is the right choice for Trojan coupling systems

• Versatility: A complete kit that covers both 3/4" and 7/8" bore configurations, making it ideal for mixed fleets or when replacing worn components on legacy and newer Trojan systems.
• Long-term maintenance: The included seal kit and boots help you refresh critical wear parts, extending the service life of your hydraulic actuation system without sourcing pieces separately.
• Practical compatibility guidance: The packaging explicitly notes the differences between early and late 7/8" designs and the non-interchangeability of some parts, helping you avoid mismatches and returns.
• Focused use cases: Designed for agricultural, industrial, and heavy equipment where Trojan couplings rely on dependable hydraulic master cylinders for precise control and braking/actuation performance.

Is this the right solution for you? If you’re servicing Trojan coupling hydraulics and need a dependable 7/8" bore master cylinder while also safeguarding spare parts for future maintenance, this pack provides a complete, standards-aligned option with the leverage leverage and base assembly you expect from Trojan. Inspect your current bore size, confirm model year design (early plastic reservoir vs. late alloy body), and then proceed with a confident fitment using TPT10392 and the included components.
