Morning chaps,

Over the last 800 miles my DSE has started with the crank harmonic balancer pully clatter that I'm sure a good few of you know about, sounds similar to the timing chain is hanging off and death is imminent. Clatters mainly when steering or when I put it under extra load at idle, ie aircon or lights, can now hear it clatter on the move around town too. If I grab the pully itself I can get it to wiggle and clatter slightly, metal to metal where I assume the rubber used to be.

I've ordered a decent used part from a P38 specialist and have a few questions as I'm getting mixed messages with the search function and yet to get Rave.

Replacing the pully requires the aircon belt to come off, the aux drive belt to be slackened then just the six bolts, not the main crank nut? Perhaps the fan assembly too? I read somewhere about removing the rad, but seems overkill.

Out of sheer curiosity as I've not had a good chance to look see how the actual unit is held together, do these tend to rattle on or will it fail quite catastrophically thowing off the belts? Planning to do it this weekend regardless.

Really appreciate you help guys.

It's easy if you remove the radiator but not a must. You got to remove the VC fan (left hand threaded) together with the cowling. The radiator hose needs removing from the radiator , otherwise can't take out the cowling. Remove the AC belt first then the main belt. The pulleys (AC & crank) held to crank with 6 bolts. No need to remove the main crank bolt. After installing, don't forget burp the cooling system.
