Partner/berlingo Hdi Crank Pulley Diameter Change

[Ozymandis 97]

I have a couple of m59 partner based estate cars that i service.

Both 2.0HDi with the infamous falling to bits crank pulleys.

i was thinking of fitting crank pulleys from a different iteration of that engine.

The original are 162mm dia, and the replacements im thinking of, are 158mm dia.

Does anyone think the 6% decrease in diameter will have any significant impact on alternator, PAS pump and in one case, air/con compressor speeds?

Thats what i thought, nice to have confirmation from someone who has actually done it.

Thanks.

If you want to do it by the book, the later engines with the solid pulley were fitted with a free-wheeling alternator pulley. Of course, by not fitting that doesn't mean that your engine is going to fall apart, but just be aware they didn't just change over to the solid pulley, without further 'downstream' changes also being made.

 

In the real world however, you probably wont notice any difference at all.

 

I think mid-2003 was the change over to solid pulley and a freewheeling alternator.

Further to this, i did a timing kit, water pump and serpentine belt to the 2004reg one yesterday,

and it had an aftermarket Corteco "traditional type" pulley, plus an obviously new alternator with the free wheeling pulley.

 

It originally had a "shock absorber" type crank pulley which had started to disintegrate, very obvious witness marks from it wobbling about and gouging the timing covers.

 

So the previous servicing bods had done the conversion.

Owner was pleased.
