I've just bought a mg ztt 190 at 99k miles but with no history so I guess to be on the safe side I'm going to have to do this soon!
A couple of questions, when doing the small belts do you leave the exhaust pulley alone? And if that's the case how do you stretch the belt to get the inlet pulley back on? And next question rather than making a tool to remove the crank pulley could you not just use an impact gun? Thanks and look forward to the next bit! |

Without the special tools, leave the exhaust pulley alone as its not keyed to the camshaft and loosen it without the special tools will screw up the timing The same applies to the inlet pulley at the front end (RH side). I found it quite easy to put the inlet pulley back on with the new belt as long as the exhaust pulley was rotated to the correct position. No need for stretching it. |

the trick is to just leave all the sprockets alone. If you are happy the car has not been tampered with, change the belts and just make sure it does not slip any teeth, like you would on any OHC or DOHC engine using belts.
Nothing much to it in that case. |

Are you referring only to the primary belt or also the secondary belts. I didn't think it was possible to do the secondary belts without removing at least the inlet sprocket. John |

No, you have to take one off each side, but they go on only one way, so the action does nothing to disturb the setting.

I'm going to look at the tensioner and idler on the ZT as there is a bit of whine from the main belt, all the belts and pump were done two years ago but I've no idea if the other items were replaced.

Thanks for the excellent pics and drawings of the locking tools and dimensions. The belts were the main things that put me off the V6 but I can see that they are a practical proposition for a home mechanic. Well done and I shall be watching for your progress.
Mike

I've noticed this on a few KV6 models I've seen invoices for - belts done, but no tensioners and waterpumps.

That might have changed now, but perhaps it was the reason for some of those cars not having the pump done? Of course, on high mileage motors it would be wise to change it anyway. And as for the tensioners, that really is false economy imo.
