2.1td with air con aux belt issues

my first post
ok belt decided to shred itself due to alignment problem on tensioner pulley .

taking that tensioner off was interesting however its not a good design realy the bush through the middle has got needle bearing marks indented in it -amazing how it could have done this to a hardened shaft

the spring damper retainging hole has elongated beyond belief .

question what if we dispense with the aircon and that top spring loaded tensioner and rely on the eccentric tensioner only is there a belt that would do the job
would there be any issues in doing this
i bet someone hads done this .

Hi Phil,

Yes, it has been done on a Xantia before now. Have a search for posts by MikeT as I know his was/is like that. Although a 1.9TD, the tensioner arrangement is the same.

I know Mike did post how the belt was routed and he may know the length. A PM might be in order if a search refuses to bring up what you need.

Not sure if he did retain the spring-loaded tensioner in use though.
One tip for a belt sizing is to run a length of cord around the pulleys and jockeys you would plan to use and see how long the piece of string is. The order the 6PK belt from a company like this one. The number after 6PK is the length in mm so a 6PK1675 will be 1675mm long.

ok well we got a NEW tensioner fitted and all ok
but its not a good solution
an engineer friend said
wht it realy needed was boring out all the needle bearings fitting a phosphur bronze bush with a hardened steel shaft going through it
i have seen 3 cars with aircon and all 3 without exception had off true adjusters

now if i only had a lathe

i have copied MikeT's modified routting of the aux belt, but it still use's the auto tensioner and i cant remember for sure the belt size used, i think something like 1152X6 rib/kp
