my son is replacing the fan belt on my car as I type - the new one is slightly longer than the old, slipping one (we think, but not by much) - is there a way of adjusting the tension, or is this done just by setting the alternator in its place?

The car is a Peugeot 106 diesel.

Any tips and hints are always gratefully received - and I'm not apologising for this being here - I need to get the biggest audience (ie help) possible.

And many many thanks for any help!!

Are you certain it's longer? If you've bought the right one it will be the same size more or less. It can also be the case that you're threading it incorrectly. It's suprising how easy it is to fool yourself

The alternator adjustment is done by moving the alternator in and out on the adjusting arm until the tension is correct and then tightening up the adjusting nut and bolt. You should then run the vehicle for about 50 miles and check and after a further 200 miles do a final check and adjust.

My only concerns are that, if it is 'too' long, you might not have enough adjustment on the arm to fully take up all the tension and secondly, if the alternator is fully extended to take up the slack, it (the alternator) just might bump or foul the engine compartment when ever you accelerate or decelerate quickly.

I spent 7 years as an RAC engineer at Watford [Northern Home Countiees] in a previous life. /forums/images/graemlins/grin.gif
 
You don't seem to have had an answer yet.

The alternator is normally held at two points at the pulley end, one on the engine block and the other to a piece of flat bar, sometimes curved and sometimes straight (don't know the car). The bar is attached at its other end to a lower point on the engine. One end of the bar has a round hole and the other has a long slot, which is on the engine and which is on the alternator varies by manufacturer.

The fan belt is tightened by loosening all the bolts, then moving the alternator until the belt tightens, then tighten the bolt in in the slotted part, then tighten the others. You may find it easier to lever the alternator outwards with a piece of wood, or similar. Don't overdo it as you can destroy the bearings. The usual recommendation is that you can deflect the belt about 1/2 inch at its longest length between pulleys.

Some deeply-experienced, but tattered, sailing peeps of my acquent use lots of these rough but rugged old engines - rescued from scrap cars - in their tattered old multihulls. As they do with tattered old Seagull Silver Centurys, and tattered old pushbikes. They've even been known to cart such a 'replacement' engine IN a Peugeot 106 from Hampshire to Corsica, and fit it to a boat wintering down there. Just an excuse, if you ask me, to slope off for a 'Jolly in January'....

I dimly remember helping bring a representative selection of the above from Lerwick to Plymouth one July. None of it worked, but it certainly amused the occasional onlookers.

You may well see these tattered old friends again on the water, or at the Beaulieu Boat Jumble, where they buy, sell and exchange last year's old rubbish for this year's. Oh, and they haunt the RNLI Auction at the end....

hmmm i keep getting that crap too... who have i offended.
(crawls back under rock).....

oh yes pug 106... not all alternators are "tensioned" by using the the above methods, before removing the old belt (Prob 2 late) pull on it, if the belt moves under tension watch the pulleys and see which one is moving it will have a hex on it for a spanner to twist it against the spring tension.....

of course this could be complete twodle /forums/images/graemlins/laugh.gif

[/ QUOTE ] Oh a lot of duff responses I am afraid. I've got a PUG 106 diesel . (Mines a 1994 1.5 with TUD5 engine.

It is one of the easiest I have come across to adjust(That is provided you dont have air conditioning.)
as it has an adjusting screw that is vertcally below the mounting. Not the usual method of pulling it by hand before doing doing up the mounting bolts.
If you get stuck PM me and I'll scan the pages in the Workshop manual.

Surprised the new one is longer than the old. You'd expect the old one to be a little bit stretched maybe.
If it is significantly longer they've given you the wrong belt. A Pug dealer should be able to cross reference with the car reistration number and give you the right one.

Get your tights off, girl. They'll get you back to the garage

[/ QUOTE ] Makes no difference you can drive it with or without tights. The auxilliary drive belt only drives the alternator. The fan's electric as you'd expect and the cam belt drives the water pump.

Pants optional too /forums/images/graemlins/laugh.gif
 
Ignore all comments about moving the alternator if your Peugot 106 is like ours. I replaced the alternator belt a few weeks ago on our 106 diesel.

There is a idler wheel which adjusts the tension. Two allen bolts to allow it to slide and then a bolt with a locknut on it that sets its vertical position and adjusts the tension. I had several trips to Halfords to get the right belt as the one that was listed as correct was far too long. Ours old 106 is 'N' reg and I know they changed the design of the alternator belt arrangement at about that age.

I assume that its one of the new flat 'ribbed' type belts and not an old style 'v' belt? My comments apply to the 'new style flat and ribbed belts.

So long since I did mine I'd forgotten the idler wheel.
My manual seems to describe the older type where the alternator moves although they had an adjuster bolt as well. Mine is one of the earliest with a 1.5 TUD5 engine and not covered awfully well by the manual that's supposed to cover up to '95.

"Poly V" is how they describe the belts I think.

I have difficulty getting the right spares sometimes but as said provided they check the Pug dealers can cross reference against the registration number.

OI!!!!!!!!!!!!!!!! I wear holdups ...

John Morris - my favourite - and only - son would like to send you his profound thanks, but only privately, you understand ... he's claiming ALL the credit for replacing the aforesaid fan belt! The sound of triumphant crowing is deafening us all, but with luck will die down in a week or so. Unless we kill him first.

Thanks to everyone for all, or almost all, suggestions. The car, unlike the mother, has stopped whining.

No worries, you can knot them together. If you're not sure, I'll show you. /forums/images/graemlins/blush.gif
