pulley

Hello guys, I will be replacing the mechanical tensioner pulley, deflection pulley (aka idler pulley?) and the v-belt in my car. My question is about torque values. I have found that the tensioner pulley is 40Nm, but I cannot find the correct torque for the deflection pulley. I have looked...

Hi All, Getting ready to take it to Chemix tomorrow to hopefully see if the new hub and arms have solved the bend preventing a proper adjustment but after doing some checks I noticed that it looked like the belt was wobbling slightly, so I stopped the engine and noticed the belt seems very...

Hello I am new to this forum, just got a e90 lci 2011 320d done 90k. It had no ac gas when I got it so I took it to my local BMW dealer for an air con system clean where they treat it with some antibacterial thing and a refill. I started noticing a squeaking noise from the engine afterwards...

Hi, I'm fitting a M52 to a kit car. I'm finding the engine is a few mm too long. Since I'm not using the Aircon, I figured a cheap solution would be to grind the outer puller off the harmonic balancer. Is this a really bad idea? Main concerns are: 1. Structural Integrity of the remaining...

Anyone know what the normal symptoms are with a failing crank pulley? When I slow down, mainly in stop start traffic in my e91 320d m47 auto, I get what sounds like a heavy vibration which then disappears when I start pulling away. Only happens when I slow right down and nearly come to a stop.

Got an annoying pulley whine on my e91. More noticeable in when revving it up, don’t really notice it on idle. It’s the older m47 engine. Is there a common pulley that goes first on these engines? Idler? Alternator? Crank pulley etc?

I've just had the top belt pulley break away on the front of the engine on my 2007 E90 330D. It's done 87k miles. With no other damage to anything else including the belt, what would it roughly cost to get this repaired in the UK including labour? I thought this would be quite a quick...

I brought a 320d Msport Touring last week at a local second-hand car dealership. It has FSH, has travelled 128,000 miles and both exterior and interior are in great condition for its age (2011). Having never previously owner a BMW before I made sure I researched the car online for known issues...

Is it possible to replace the pulley on the idler tensioner with out changing the full unit?

As above please. Also a diagram the way the belt wraps around. Thanks

One or more of the pulleys to my fan / alternator is noisy. It makes a grating sound for a short while when starting, noticeably so when the weather is cold. I once had one of these fly off on a Saab. I was wondering if there is any quick way of lubricating these to prevent them getting any...

Hi folks, I've just bought a '93 525i with the M50 engine. It's got a slight engine vibration at around 2200 rpm which I suspect is down to the harmonic damper on the front pulley. I can get a used one for £20 but wondered if anyone had any experience of what is required to change it - is it...
