Quote from: Joesson on January 9, 2023, 14:11As above, it's an auxiliary belt, (not a cam belt) , so when it does go there is not such an immediate consequence.

My car is twenty years young, perhaps half of the annual services were done by Mr T.Once prior to my ownership and once in my ownership Mr T reported such a leak as being apparent and requiring a replacement pump.The independent garage that also serviced it and myself for the last 8 years have been unable to find any evidence.Perhaps it's part of pre emptive maintenance by Mr T!PSMy daily, a Ford that I bought new, has been serviced exclusively by the Main Dealer., the service is inclusive of Ford breakdown and recovery service. On 99K + now, a few years ago the cam belt was replaced as recommended by Ford.I have read elsewhere that the water pump should be considered for replacement at such a time. The workshop Manager, the son of the MD of the garage considered the water pump to be very reliable and did not believe it warranted replacement. He also recommended an after market cam belt, at less cost than the Ford item. So far so good.Perhaps just a different customer relationship.

Quote from: Dev on January 11, 2023, 15:03After further recollection I have to make an amendment. The overrun alternator pulley might not be a dumb idea, it is after all an OEM Toyota part that is now widely used across the industry.
Quote from: Petrus on January 12, 2023, 09:03btw though there is no doubt whatsover that the OEM harmonic damper crankshaft pully works, the ponderings about the freewheel alternator pully concerning the load on the belt put this in a spotlight. Any change in forces on the belt is a change in the forces on the outer rim of the crankshaft pully. Now, the high frequency vibrations on the crankshaft are basically in their own universe but the damping is a result of the weighty outer rim doing a different thing with a rubber strip between the two. Changing the ´weight´ of the outer rim changed the dynamics of the danmping. I mean, if the freewheel in the alternator pully makes life of the belt easier the effect on the pully harmonics múst be more than negligeable no?!Travelling a bit further on this road, fitting a lighter flywheel, lighter underdrive alternator pully, fitting/deletng the AC pump, will all change the dynamics of the harmonia The moral of it being that when leaving all stock the story is clear: OEM is best. Any modifications change the dynamics and I personally have no doubt whatsover that while the mod. may have a benificial effect one desires, on the whole it will be a compromise with the OEM balance. Basically pick your venom when you go off the OEM path.
