discomikey Posted February 11, 2012 Share Posted February 11, 2012 my land rover decided to sieze its tensioner pulley yesterday on the way home from uni, luckily id only got a couple of miles before it seized. not being able to find one on a friday afternoon, i set about bodging it by replacing the bolt with a thinner one and lathed up a brass bush. it got me home JUST. now all the balls have gone from the bearing and i am in dire need of a replacement before monday which is a big ask i know because everywhere useful shuts today at lunchtime. i assumed it was a 200TDI air con tensioner pulley from a disco as thats where i got it from. but the ones i can find online are different and clamp around the fuel pump cover. which i cant use that setup for my application.

Landy-Novice Posted February 11, 2012 Share Posted February 11, 2012 i can't find anything like that! are you sure its a land rover part? could you try a place like this? they may make you one up? and there only 20 odd miles away from you.

discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 im not sure its a land rover part. no. this is what confused me as my disco had factory fit air con too. but no signs of the other type of tensioner. i have no other engines lying about it could be from either as the rest are all serpentine belts.

western Posted February 11, 2012 Share Posted February 11, 2012 Can't find any like that in the parts books, only these I've listed below. Defender 200Tdi air cond tensioner http://www.numcat.ru...ver/p/31/53134/ 2.5 TD variant http://www.numcat.ru...ver/p/31/53092/ Discovery 200Tdi variant http://www.numcat.ru...ver/p/32/45511/ 300Tdi variant http://www.numcat.ru...ver/p/32/45550/ are there any makers name or numbers stamped on your item ?

ejparrott Posted February 11, 2012 Share Posted February 11, 2012 There is no tensioner like that on my disco 200, but there is one on the aircon mount bracket for the sanden aircon pump which is to be fitted to my 109. What was it tensioning? Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted February 11, 2012 Share Posted February 11, 2012 ..... now all the balls have gone from the bearing and i am in dire need of a replacement before monday which is a big ask i know because everywhere useful shuts today at lunchtime..... Taking a different approach can you not just replace the bearing? Do you have any machining facilities? You could open the pulley up a bit to take a larger bearing if you happen to have one kicking about ...... Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 it did come from my air con system when the TDI was in the disco. hence me thinking it was standard. i cant see any coding on it. i am going to have to get a bearing for it. but wont be able to get one till monday. if i could have located where it was from i could have maybe got hold of one. but now i have no ride back to uni ahh the joys of lr ownership.

CwazyWabbit Posted February 11, 2012 Share Posted February 11, 2012 What about your other series? The one that has no brakes ...... ah, I just answered my own question Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 11, 2012 Share Posted February 11, 2012 it did come from my air con system when the TDI was in the disco. hence me thinking it was standard. It's used on the aircon system, not required if you havent got aircon, like my 88, so what have you been using it for? I've just had a look back at your build thread and I can;t see it on the engine. Its definately not the LR aircon tensioner Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 i used it to tension the water pump belt. like so. can just see it. its the perfect spacing from the PAS plate to where the belt needs to be. the double pulley on the alternator didnt last very long at all. it was the PAS double pulley with a new center welded in. it wobbled like crazy even though the hole was perfectly centered even in a lathe.

discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 its not a V8 part is it? Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 11, 2012 Share Posted February 11, 2012 Oh now I see! I thought you'd used the PAS pump somehow, using the plate confused me!! Why not convert it to have the alternator to the PAS pump position? Uses some spacers, a 2286 alternator mount and the fan belt from the disco engine, have you such an alternator bracket to hand? It wouldn't take more than a few hours to do tomorrow, get you back on the road, gives you more room in the engine bay too - a premium on a Series I know!

ejparrott Posted February 11, 2012 Share Posted February 11, 2012 its not a V8 part is it? Doen't look like it, the 200 disco has the same P/N as the V8 Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 okay thanks. the way i have it set up is for increased reliability. space isnt so much of an issue anymore as my series wings have defender inners and a lot more bay space. if the alternator belt goes, i still have the water pump and cooling. the battery should get me somewhere i can pull over to fix it. if the water pump belt goes, i still have charge and i should be able to get somwehere i can pull over to fix it.

ejparrott Posted February 11, 2012 Share Posted February 11, 2012 Well I understand your thinking, only your increased reliabilty seems to have gone out the window with a spurious part! My 109 has 90/110 inner wings, it does make a big difference. Looking at the 200 aircon tensioner, if you welded a spigot to the PAS pump mount plate, you could use it. I guess from a previous comment you have a lathe at the farm? If you need the diameter for the spigot I can go and get the tensioner and measure it up for you, although I'm guessing you won't be able to get one before you need Brian anyway?!

discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 no lathe, that was at harper. used to get me home. i wish i had a lathe :/ Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 11, 2012 Share Posted February 11, 2012 Thats a bummer, rules out fitting a new bearing aswell then. Anywhere at Harper you could get another bearing to fit to the pulley on monday, with a lathe avaliable to bore out the pulley if required?

discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 the bearing should press out though so i should be able to fit it. the pulley hasnt been modified, only the siezed bearing to take the bush. but should be able to get a bearing to size for pretty cheap.

discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 i cant see any numbers, but my suppliers should be able to determine the correct bearing anyway theyre pretty good they just dont tend to have it in stock the day yuo want it, and arent open saturday mornings.

CwazyWabbit Posted February 11, 2012 Share Posted February 11, 2012 Measure it up .... you never know you may be able to rob a bearing from something else to get you by. Or could you mount a pulley from some other tensioner/idler on the bracket part? Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 ive thought about this. i have about 4 different pulleys about, all with perfect bearings in.... for serpentine belts haha Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted February 11, 2012 Share Posted February 11, 2012 Guess that'd make a mess of your V belt pretty quick! None of them got the same size bearing as the knackered one? Quote Link to comment Share on other sites More sharing options...
discomikey Posted February 11, 2012 Author Share Posted February 11, 2012 nahh. too wide. that would make life easy remember haha ive parked Brian next to the 50th anniversary 90 in my yard. to try and shame him into fixing himself in the prescence of a V8... doubt its going to work.
