Product Overview
TGEC spare parts are engineered to TGEC specifications, ensuring reliable performance, proper fit, and extended service life when replacing worn or damaged parts during routine maintenance or major repair. TGEC supplies parts covering the full TGEC breaker range – side-type, silenced box-type, top-type open-body, and fully-hydraulic gas-free R, M, and V series. Whether you need a seal kit for 500‑hour service, a replacement piston for an overhaul, a front head and bushing assembly, or through-bolts and hoses for a fleet maintenance program, we supply the correct genuine parts for your specific breaker with fast shipping to minimize downtime. Part of the TGEC excavator breaker working tools and spare parts lineup.
Using genuine TGEC parts helps maintain breaker performance and reliability. Parts with incorrect dimensions, material properties or quality standards can lead to accelerated wear, reduced impact energy, hydraulic system damage or premature failure. All TGEC parts are manufactured from certified materials – high-strength alloy steel for pistons and front heads, precision-ground valve components, polyurethane and HNBR seals rated for high pressure and temperature, and phosphor bronze or induction-hardened alloy steel for bushings – all processed through the same quality control and inspection as original production components. The spare parts program covers every breaker model from compact 0.5 ton mini excavator units to heavy-duty 160 ton quarry and mining breakers, with parts catalogs organized by series and model for quick identification. Dealers, rental fleets, quarry operators, and mining companies get volume pricing, dedicated account management, and custom parts kits tailored to specific breaker models and maintenance schedules.
Spare Parts Categories

Parts specs are for reference only. Actual parts may vary by breaker model and production configuration. Contact the TianGe parts team with your breaker model and serial number for accurate identification.
Seal Kits and Routine Maintenance Parts
Seal kits are the most commonly replaced parts and form the core of routine breaker maintenance at 500‑1000 hour intervals. TGEC seal kits include all seals needed for a complete service – piston seals, valve seals, front head seals, accumulator seals where applicable (for gas-charged models), O-rings, backup rings, and wear rings – all made from premium polyurethane and HNBR rated for 250 bar and -40°C to +120°C. Each kit is specifically calibrated for the breaker model and series with correct sizes, materials, and quantities. Using seals with incorrect dimensions or material properties can lead to leaks, reduced energy, and internal damage.
Other routine maintenance parts include front head bushings, retaining pins, hydraulic hoses, and through-bolts, all of which wear during normal operation and should be inspected and replaced at regular intervals. Bushings guide the working tool – replace them when clearance exceeds the manufacturer limit (typically 1.5–2 mm depending on the model). Excessive clearance causes tool misalignment, vibration, and accelerated piston and front head wear. Retaining pins should be checked for grooving or cracking. Hoses should be replaced at the first sign of leaks or abrasion. Through-bolts should be torqued to spec and replaced if stretched or damaged. TGEC supplies all routine maintenance parts individually or as custom kits tailored to specific breaker models and service intervals.
Major Overhaul and Internal Components
For major overhauls, TGEC supplies pistons, front heads, and valve assemblies. Pistons are 42CrMo forged alloy steel with precision-ground surfaces achieving 58‑62 HRC hardness and Ra ≤ 0.25 µm finish for exact fit and seal performance. Front heads are high-tensile alloy steel with induction‑hardened bushing bores, reinforced for heavy impacts, available with or without bushing assembly. Valve assemblies feature precision‑ground spool and valve components with low‑backpressure design, calibrated for specific flow and pressure ranges, supplied as complete ready‑to‑install assemblies. Major internal components may also include cylinders, back heads and accumulator-related parts depending on breaker model. All major components go through the same rigorous quality control as original production parts – dimensional verification, hardness testing, surface finish measurement, and pressure testing where applicable – ensuring replacement parts meet TGEC quality standards.
Parts Identification and Ordering
To ensure accurate parts identification, provide the breaker model number and serial number to TGEC parts support. The model number identifies the series and size (e.g., TG‑S100 for a side‑type 100 mm model), and the serial number verifies production configuration for older or modified breakers. Once confirmed, the correct parts can be found in the TGEC parts catalog, which lists exact part numbers, dimensions, and availability. If the model or serial number isn't visible, parts identification can be assisted with photos of the breaker and existing parts, or by measuring key dimensions of the component. Common wear parts like seal kits, bushings, and retaining pins are typically in stock for fast shipping within one to three business days. Less common components or major internal parts may be manufactured to order – our parts team can provide estimated lead times. All spare parts orders include a detailed parts list and installation guidance, and our technical support team is available for questions.
Fleet and Dealer Parts Programs
For equipment dealers, rental fleets, quarry operators, mining companies, and contractors who maintain multiple breakers, TGEC offers specialized fleet and dealer parts programs with volume pricing based on annual purchasing volume, dedicated account management, and custom parts kits tailored to specific breaker models and maintenance schedules. Dealers get wholesale pricing and marketing support to build a profitable parts and service business. Rental fleets get custom field service kits with the most commonly needed parts for quick repairs and minimized downtime. All fleet and dealer programs are tailored to your needs, breaker models, and applications – our parts program team works with you to develop a customized procurement plan that maximizes uptime and cuts total maintenance costs.
