This document is a service and repair manual for Hyster Internal Combustion Engine Trucks, specifically models B236 (H400HD, H450HD, H400HDS, H450HDS) and related variants. The manual focuses on the transmission repair for TE13 and TE17 transmissions, which are integral components of these heavy-duty lift trucks.

Function Description:

The Hyster B236 series of lift trucks are internal combustion engine-powered vehicles designed for heavy lifting and material handling applications. The core function of these trucks is to transport and lift heavy loads in various industrial environments. The transmission, specifically the TE13 and TE17 models covered in this manual, is responsible for transmitting power from the engine to the drive wheels, allowing the truck to move, change speeds, and reverse. The TE13 and TE17 transmissions are designed for robust performance in demanding conditions, facilitating the precise control and power delivery required for heavy-duty operations. The TE13 transmission is typically fitted on trucks with a 142 kW engine option, while the TE17 is used with the 164 kW engine option, indicating their suitability for different power outputs and load capacities.

Important Technical Specifications (as inferred from the document):

Transmission Models: TE13 and TE17.
Engine Power Compatibility: TE13 for 142 kW engines; TE17 for 164 kW engines.
Truck Models Covered:
- H16.00-18.00XM/XMS-12 (H400-450HD/HDS) [A236]
- H16.00-22.00XM-12EC (H400-500HD/HDS-EC) [B214]
- H16XM-12, H18XM-12, H20XM-12, H22XM-12 (H400HD, H450HD, H500HD, H550HD) [B236]
- H16XM-12EC, H18XM-12EC, H22XM-12EC (H400HD-EC, H450HD-EC, H500HD-EC) [C214]
Key Transmission Components: Torque converter, multiple clutch drums (1st, 2nd, 3rd, Forward, Reverse), output shaft, stator support, pump drive gears (idler and main), control valve assembly, various bearings, seals, and gaskets.
Lifting Capacity Requirement for Transmission Removal: A lifting device with a minimum capacity of 1000 kg (2205 lb) is required to safely remove the transmission.
Special Tool Dimensions (for FWD/3RD shaft assembly): Ø52.50 mm (2.07 in) diameter, 90 mm (3.54 in) height, 470.46 mm (18.52 in) overall length. This tool is crucial for preventing gear drop during transmission manipulation.
Clutch Design: The difference between TE13 and TE17 models also includes the number of discs in the clutches, suggesting variations in torque capacity and power handling.
Torque Converter: An essential part of the transmission, responsible for fluid coupling between the engine and the gearbox. The manual details its removal and disassembly.

Usage Features (implied from repair procedures):

Heavy-Duty Application: The truck models and transmission types indicate use in environments requiring significant lifting and robust operation, such as construction sites, ports, or large warehouses.
Internal Combustion Engine: These trucks are powered by internal combustion engines, requiring fuel (Gasoline, LPG, CNG, Diesel) and associated fuel system maintenance.
Hydraulic System Integration: The transmission interacts with hydraulic pumps, which are disconnected and removed during transmission servicing, indicating an integrated hydraulic system for various truck functions (e.g., mast operation, steering).
Electronic Control: The presence of engine speed, temperature, and drum speed sensors, along with wiring harnesses, suggests electronic control and monitoring of the transmission's operation.
Drive Plate Connection: The transmission connects to the engine via a drive plate and flywheel, which must be carefully handled during removal to prevent damage.

Maintenance Features:

The manual is primarily a guide for detailed maintenance and repair, emphasizing safety and correct procedures.

Comprehensive Disassembly/Assembly Instructions: Step-by-step procedures are provided for removing, disassembling, cleaning, inspecting, and assembling various transmission components, including:
