  1. 2004 E46 318ci (N46) - Torque setting for deflection pulley

    BMW 3 Series Forum - Technical Talk on the BMW E46
    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...

  4. M52B28 TU Chopping Aircon pulley off the harmonic balancer

    BMW 3 Series Forum - Technical Talk on the BMW E46
    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...
  5. Crank pulley failure symptoms?

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    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.
  6. Aux belt pulley whine e91 320d m47 engine

    General BMW Discussions
    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...

    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...
