[AndyW] Ducati use the harmonic method of checking/adjusting timing belt tension and quote the relevant frequencies / tolerances in the Workshop Manual;-) The YouTube video from CA Cycle Works shows the new belts slipped onto the pulley with little problem. Natural frequencies vary based on the stiffness of the belt and can be measured by plucking the belt and reading the frequency response of resulting vibration. A method to calculate the Natural frequency of the Timing belt drive is developed and validated. If the belt is under tension, this will cause it to vibrate at its natural frequency (i. Here’s how it works: First, enter belt mass constant, belt width and span length into meter using built-in keypad. Belt tension is adjusted at the factory using an expensive meter to measure the audio frequency of the belt when it is plucked. The same result would have been achieved by re-tensioning the old ones. Since these pumps fail often (even before the timing belt), they should be replaced any time the belt is replaced. TTC is a new universal belt frequency tester for checking correct cam belt tension frequency and can be used with all belt types and all vehicle types. Subject of change. The tensioners vary a bit but most need a ratchet to detension while removing/fitting the belt.

Timing Belt How to replace timing belt on Jaguar XJ 3. (400-489 N). The drive belt tensioner pulley is mounted on an eccentric mandrel, the torsion spring turns the mandrel to keep constant tension on the pulley/belt when it's tensioned properly. The optibelt Laser Pointer II makes it easier to align belt drives. The test methodology is based on the theory of vibrating strings. The motor produces 30 in-lbs of torque. We have a timing belt arrangement producing linear motion by being constrained (from translation) by a drive pulley on the same stepper motor, a free spinning pulley bringing the belt into proper tension, and a cart attached to one "side" of the belt. 2-liter engines, do not need their timing belt replaced until they hit 92,000 miles or after six years, whichever comes first. the frequency that occurs with free vibration rather than with a constant forced vibration). Start the engine. After removing the front covers, pull the water pump off for inspection if it is the type driven by the timing belt. Out of interest before and after I replaced the belts, I checked the tension using the allen key method as I had previously used this method on my 620, but I thought it was a little crude for my liking. As well as ensuring correct tensioning, it is also important that the pulleys are aligned correctly. Drive misalignment.

Timing belts need to be replaced on a specific schedule. For engines it said oil should be changed every 4000 miles and timing chains every 60,000 miles, or they could snap and wreck the engine. Anyone can operate the Sonic Belt Tension Meter by inputting the belt width and length, and then holding the sensor near the belt to measure its vibration. Listed manufacturers, suppliers, dealers & exporters are offering best deals for timing belt tensioner. Having the correct tension though keeps the cam timing right, too slack and it will be retarded. Proper tension corresponding to the belt width can be calculated. Proper timing belt replacement involves much more than just replacing the belt. Skip navigation Sign in. Frequency tension testers claim to be especially suited for tensioning synchronous belt drives. 2L 40 valve engine. After seating the belts in the groove and adjusting center distance so as to take up slack in the belts, further increase the tension until only a slight bow on the slack side is apparent while the drive is operating under load. The use of a microcontroller enables highly accurate and highly reproducible results. To use CBMTool you will need a PC, ideally a laptop, and microphone such as a tie clip microphone.
