Pulley-idler ancillary drive - BROKEN! NEED ADVIDE

I have a ROVER 25, 2.0 IDT, YEAR 2000, WITHOUT A/C but with this " Pulley-idler ancillary drive" - Part no. PQR101000 -

http://www.rimmerbros.co.uk/ItemImag...0654-Large.jpg

and it use a belt for an A/C car(extralong), and now has broken



My question is: Can i cancel these PULLEY AND USE A NORMAL BELT FOR NO-A/C ROVER because i don't find these pulley without his support(mount)?

I'm from Romania and here i find only original piece...and it's expensive!

This is Rimmer Bros in the uk. They will post, but I presume this is still expensive for you?

I don't think you can use a non air con belt because there were other differences on earlier models that had no air conditioning fitted. I think the alternator mounting point was also different.

Pully makes tension of the belt. Without pulley you might have slipping belt.
You can mount replacement pully. Measure its diameter and width and see size of mounting hole, and you can try to find replacement one.

The idler the poster is talking about is not the tensioner. It is the dummy idler used to replace the aircon compressor in non-aircon cars.

Short answer is yes that should work in your case I believe.

Another option would be to repair the original idler pulley. You could either fit a larger bearing or weld repair the pulley back together. I actually built one myself out of a spare vacuum pump and some steel plate (I needed a smaller pulley as I was fitting the engine into a smaller engine bay).

One last option is to obtain a used part here in the UK and send it over. It isn't a common failure so someone may be able to help.

I wanted to weld but it's a piece of torn pulley bearing and do not believe they can balance and better ball bearing in a pulley for not eccentric spin and then break again.

Balance won't be a problem providing you make sure the pulley runs concentrically. You would certainly have to weld in a a new hub and machine the bore of bearing housing afterwards. This would be my solution and it would ensure it rotates true.

I have done repairs to my cars, such as making new a new main seal for my oil cooler using an aluminium disc and o rings and a new nylon pivot bearing for the aux belt tensioner, they have all lasted well and are still lasting to this day. I repaired the oil cooler over 100k ago. So don't be afraid to re-engineer providing you have access to the equipment or people who can do it properly.
