The Complete Guide to Polyurethane Timing Belt Replacement

The polyurethane timing belt, also known as the PU timing belt, is a widely used industrial belt. Its major role is to provide proper coordination to the different moving components of the machine. The PU timing belt provides the proper timing and movement, which also reduces the chances of valve collision. Though the timing belt is robust and can withstand extreme temperature fluctuations, the polyurethane timing belt can wear out, so if you want to maintain optimal performance, you must know everything about its replacement. 

Why is it Essential to replace the Polyurethane Timing Belt?

The PU timing belt plays an essential role in coordinating the conveyor belt.  The timely replacement of the timing belt is essential to prevent unexpected business failures, which can lead to costly downtime, equipment damage, and production delays. By replacing the worn-out polyurethane, you can prevent the unexpected belt failures that can lead to production delays. By replacing the worn-out timing belt, you can ensure uninterrupted operations.

Signs that You Need a Polyurethane Timing Belt

Here are some of the signs that the polyurethane Timing Belt needs replacement:

• Engine Malfunctions:

 Polyurethane timing belts run through a system of pulleys that operate both the camshaft and the crankshaft. The teeth they use for this are meant to grip and move smoothly, but if the timing belt starts to wear out, it may create a repetitive clicking or ticking sound coming from inside the engine. 

• Smoke after starting the equipment’s motor

Polyurethane belt wear and stretching damage the catalyst, as the fuel is not completely burned in the chambers due to an incorrect composition of the fuel mixture. That means: all the fuel that has not been consumed is directed to the exhaust system. If you hear a clicking noise when starting the engine and see black smoke coming from the vehicle’s exhaust pipe, this indicates an incorrect fuel composition that may be due, among many others, to damage to the timing belt.

• Difficulty starting: 

 A worn polyurethane timing belt will affect your engine’s starting speed as it is attached to the pulleys that drive the crankshaft. Eventually, the belt can slip on the camshaft drive, causing the engine cylinder to open and close at the wrong time.

The stretching or wear of the timing belt will cause it to skip one or more teeth, and therefore as a result the engine ignition is lengthened, in addition, as we have already mentioned, the jumps or slips of the belt cause the desynchronization of the engine.

How to Replace the Polyurethane Timing Belt?

You can start by gathering the necessary tools, including a PU timing belt, tensioner tool, and service manual, to do the precise work. 

Belt Removal: Loosen the belts and remove the old timing belt. Properly check the routing and installation of the belt so that you can do the same with the new one.

Inspection: Check the tensioners and other parts of the timing belt for any wear and tear. Replace the old and damaged parts so that there are no issues in the future. 

Installation: Install the new PU timing belt according to the manufacturer's instructions, ensuring proper alignment of tension and stress distribution.
