Thread: Knock Knock?

Could be the tensioner spring broken, they jamb against they other half and still kind of work, the belt flaps a lot, making a small racket that can't readily be identified or the tensioner pivot bearing damaged (can't be replaced) and again belt flaps on loose tensioner.

Never seen a steel pulleyed one, except mine as it has a falcon pulley the right size and a double bearing.

yeah I don't get it either.. but when the belt was taken off and every thing that runs on it was tested for soundness, everything came up trumps. Except for the severely delaminated belt... ( chunks out in multiple places as well as cracks all the way around).


I'm probably going to get shot for this but will proceed because it is interesting and useful for someone else who doesn't mind a bodgy job to get out of trouble some time

Due to a little late organisation on mechanics behalf (must have left it until today to grab the parts instead of buying them when I booked the car in), he was not able to get the right size belt, so he has temporarily improvised with the next size shorter one and skipped a pulley. (he tried to call me, presumably to put me off a couple days but I was already on my way to pick car up and had misplaced my phone). The right belt is coming but meanwhile, i have this;


Hard to photograph but the shiny one has been bypassed (have been assured the only thing affected by this will be the aircon, so will not use aircon till proper belt is on). It is running perfectly, no sound at all, so unless that is the pulley that is dying (though he says it isn't) it really was just due to the belt. Going by that damage I'd say it's very lucky I've been mainly commuting via train to get to work for the last 6 months
