    Default Td5 Crank Pulley

    Hello all, got the front end stripped out on the td5 at the mo to flush the intercooler out. While I was there I took the fan belt off and checked all the components it runs on were ok. Now then, the damped crankshaft pulley is like that I can rock the part that the belt runs on just a little back and forth while the middle is still.
    Is this Ok? or is the damped pulley on the way out?
    It dose not feel like its going to fall apart or anything.

    By the way to get the intercooler out is a right cow! See photos!
    It is a good time to wire brush and waxoyl the power steering pipes that run under the radiator, also that part of the chassis.
    Cheers
    Tom

    Are you sure it is the pulley outer moving on the inner part? If it is, it sounds a bit past its sell-by date. They are rubber bonded if the same as the V8 one, and should be no play at all, unless there's a separate bolted pulley section that is loose.

    We put new power steering pipes on our V8 when we did the engine, and painted them first. Old ones were rotten.

    I'm no expert coz I didn't do the work but - when I recently found that a idle speeds the engine was rattling like a bucket of spanners, it turned out to be the pully/damper. The spanner man just tightened up the three bolts that hold the whole thing together and it's good as gold now... I say "just" - it meant getting the viscous fan off to get AT it and that was of course fun...

    I know they have them on the 19J turbo engine, as my son has one in bits at present, and that is a 3-bolt pulley section.

    Wasn't sure if Tom's was the same type of construction.

    Yes its got the 3bolts that look like they hold the outer part onto the flexi mounting and the crankshaft bolt in the center. Do I just need to tighten the 3bolts up like that?
    I can get about 1mm or so of movment either way (with my hands) on the outer part of the pulley while the inner is still.

    Crankshaft Pulley TV Damper Bolts 80nm or 59 ft lbs torque, Tom, so fairly tight. Sounds as though yours have run loose?

    The main pulley bolt is 460nm or 340ft lbs.
