Product Specification

Truck Clutch Pressure Plate 33482000553

I. Product Overview
Part number 33482000553 is a high-performance clutch pressure plate assembly specifically designed for medium and heavy-duty trucks, buses, and various types of construction machinery vehicles. As the core executive component of the clutch system, its primary function is to smoothly and reliably engage and disengage the engine power from the gearbox by pressing or separating the clutch friction plates (clutch discs) under the driver's operation. This ensures smooth vehicle startup, stable gear shifting, and effective power transmission.
This model has been precisely designed and manufactured, with its outstanding durability, stable performance, and wide adaptability, making it an ideal original factory accessory or high-quality replacement part for many mainstream commercial vehicle brands and models.

II. Product Features and Advantages

•  1. Outstanding Heat Resistance and Wear Resistance:

◦ Material: The disc body is usually made of high-strength cast iron or special steel, which undergoes a special heat treatment process (such as quenching + tempering) to achieve an extremely high surface hardness, wear resistance, and thermal fatigue performance. This effectively resists the heat and wear generated by heavy loads and prevents the occurrence of hot cracks and deformation.
◦ Diaphragm Spring: Made of high-quality high carbon chromium alloy steel, the diaphragm spring has undergone precise stress calculation and fatigue testing to ensure uniform pressure distribution, easy separation, and long service life with anti-degradation capabilities.

• 2. Smooth Power Transmission:

◦ The working surface of the disc is finely ground to ensure a large and uniform contact area with the clutch plate, providing smooth and vibration-free power engagement, enhancing driving comfort, and protecting the transmission system from shocks.

• 3. Precise Adaptation and Compatibility:

◦ This part number strictly follows the original factory specifications and standards for manufacturing, ensuring perfect matching with the flywheel, release bearing, and clutch plates of the specified vehicle model, making installation convenient without the need for modification.

• 4. Strong Load Capacity:

◦ Designed specifically to cope with harsh conditions such as truck heavy loads, climbing slopes, and frequent starts, it has extremely high clamping force and torque capacity, ensuring efficient power transmission without slippage.

V. FAQs (Frequently Asked Questions)
Q1: Is it necessary to replace the clutch disc at the same time when installing this pressure plate?
A: It is strongly recommended to replace them together. The clutch pressure plate and clutch disc form a pair of friction pairs that work together. If only the pressure plate is replaced while using old, worn-out clutch discs, it will lead to mismatched contact surfaces, which not only affects the performance of the new pressure plate (such as shaking or slippage) but may also cause early damage to the new pressure plate due to uneven wear of the old disc. For optimal performance and the longest service life, it is recommended to replace the pressure plate, clutch disc, and release bearing as a "clutch three-piece set" together.
Q2: When do I need to replace this pressure plate?
A: Common symptoms include:
• Clutch slippage: The engine speed increases but the vehicle speed rises slowly, especially noticeable under heavy loads or when climbing uphill.
• Incomplete separation: Difficulty in shifting gears, with gear collision sounds when engaging gears.
• Starting shake: The vehicle experiences abnormal shaking during starting.
• Abnormal clutch pedal feel: The pedal feels too heavy, too light, or lacks power when rebounding.
• Unusual noise: Hearing an unusual sound when pressing or releasing the clutch pedal.

3: How to extend the service life of the clutch pressure plate?

A: Standard operation: Avoid half-linkage while driving by stepping on the clutch pedal; fully depress the pedal

when shifting gears; reduce the habit of abruptly lifting the clutch for starting.
 

• Reasonable load: Avoid long-term overloading, as it can greatly increase the load on the clutch system.
 

• Regular inspection: Check the free travel and wear of the clutch according to the vehicle maintenance manual

requirements.
 

Q4: Is this pressure plate suitable for all trucks equipped with the same model engine?
 

A: Not necessarily. Even if the engines are the same, there may be differences in transmission interface and

flywheel size. The most reliable way is to provide the brand, model, engine model, transmission model, and

Vehicle Identification Number (VIN) of the vehicle at the same time, so that professional accessory personnel can

accurately query through the catalog to ensure that the parts are fully matched.
 

Q6: Does the product have a warranty?
 

A: Yes. We provide a [for example: 12 months or XX thousand kilometers] quality guarantee for this clutch

pressure plate (please refer to the warranty instructions at the time of purchase for specific terms). Please keep

the purchase receipt properly.
