Thread: TDV8 Auxiliary Belt Refit Help

I have the correct way/direction/location of the belt fitting on the pulleys but cannot get it on. With the tensioner all the way back it just is too tight.
I would appreciate thoughts or ideas on how to refit this belt!

Thanks in advance.

Are you sure the bottom of the belt is sitting correctly in the crank pulley and not riding on the edge?

I have struck this on a couple of vehicles in the past. Reason some one before hand has fitted the wrong belt. Goodness knows how they got it on in the first place though I had this on a Nissan pulsar timing belt and also on a TD5 Defender , a customer took a belt off and refitting it it wouldn't go back on, they had to undo the A/C compressor bolts to allow the compressor pulley to tilt forward slightly to gain a 1mm or 2 to slide the tight belt back on.

I had a look at Microcat and I think this is how the belt should be routed.

Thanks for that. Confirms I have it correct.

Well, still having no luck getting this belt on. Seems way to tight.

Feels like some how it has shrink!!!

Are you trying to slide it over a smooth, edge-less idler pulley or over one with ribs and an edge? The large idler pulley (#7) would be my choice as the small one is too close to the water pump pulley.

Tried both

Tried different pulleys etc. belt is just so short compared to Alternator belt to put on. Have got it correctly, as per topic, on
