Fan/Alternator Belt and Steering Pump Belt adjustment SNAG!!


Recommended Posts

On attempting to adjust both the fan drive belt and the power steering pump drive belt on my Defender 200TDi I find that some bright spark has rounded off the heads of all of the pivot bolts and adjustment bolts on both the alternator and the steering pump - all 10mm. The bolt on the alternator adjusting strap (13mm) has undone but even here I find that the original bolt has been replaced with a nut and bolt (he must have stripped the original) with no washers being used! I know that this must be a pretty bog-basic engineering dilemma but I am at a complete loss as to what to do next.

I managed to adjust the fan belt with a bit of gentle tapping on the alternator but I am now sweating on what happens when I have to change either or both belts – and that will not be long by the look of them!

Has anyone got any good ideas? Is there some sort of bolt extractor that I can buy that could get the job done? There is precious little room to get in and drill them out!!

Well , I didn't believe I would learn so much!

Thanks to Western for those links to the retroanaconda site with the parts lists etc; I hadn't seen that before and it's great. I've taken off the fan and fan shroud to get better access and am now driving around without them. (It would be interesting to know what sort of ambient temperatures a 200Tdi will run in without needing the fan!)

LandyManLuke's suggestion of using the 6-sided socket is the next thing I am going to try, once I have got hold of some spare bolts in case of breakages.

ajh's info about the Irwin bolt extractors got me straight onto their site and I have ordered a set from tools247 on Amazon.co.uk for a pretty good price I think, and postage at a fair rate.

I have ordered the two belts from Paddock Spares but they are unable to supply replacement mounting bolts. I am a bit out in the sticks here and I need to find a motor factor somewhere who has something similar.

So until I have the bits and pieces together I am holding off trying again. BUT I am out of the despair I was in and confident about getting the job done, thanks to all of you for your advice. I will be back to tell you all how I get on. Cheers.smile.gif
