benthegardener Posted May 29, 2014 Share Posted May 29, 2014 I'm in the process of changing my screaming PAS pump when I noticed what a cobble together the alternator mounting is on the car. I have a 12L (Disco) 200tdi in my 110 HiCap, I ve always had a slight glow from the battery light, and while removing the old pas pump today I noticed the bottom lug was snapped on the alternator. There's also bits of plates and nuts and washers making spacers in there the whole thing was a mess. Does anyone have a picture of what a 200tdi alternator and power steering pump should look like on the engine. Also I think the belts were wrong. one belt was driving the pas only. the other the alternator and fan. Is that right? Lastly what is the difference between the 200tdi and the 19j pas pump? Thanks in advance for any help Ben Quote Link to comment Share on other sites More sharing options...

ejparrott Posted May 29, 2014 Share Posted May 29, 2014 One belt for PAS and another for alt and waterpump is correct for defender spec TDi Quote Link to comment Share on other sites More sharing options...
benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 Thank you. This is getting stranger and stranger. The bracket assembly that the alternator and pas pump mount on seems to have been cut at some point so the alternator wont fit on. I'm guessing this is what the extra, couple of hex nuts and washers that fell out were doing, spacing out the bottom bolt. Looks like I need a new ERR1115 looking at the links posted above.

benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 I'm going to try and post a picture ERR1115 is no longer available apparently. Does anyone make an aftermarket alternator/pas pump mount? Or am I going to be better trawling breakers ebay etc Ok This is what I've got It's been cut away here Closer view Thanks again in advance for any help or ideas Ben Quote Link to comment Share on other sites More sharing options...
western Posted May 30, 2014 Share Posted May 30, 2014 I'm not overly familiar wit the Disco 200tdi parts, but that bracket looks as though it's been butchered at some point, the strap at engine block is not a standard item. best bet would be ebay or a LR breaker. found a new one here http://www.jle4x4.com/boutique/support-pompe-alternateur-moteur-p-1664.html but it's in France cost 70 euro plus post/vat Quote Link to comment Share on other sites More sharing options...
benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 Think I've found one on ebay. Should arrive Tuesday, hopefully that'll help start to sort it out. Quote Link to comment Share on other sites More sharing options...
western Posted May 30, 2014 Share Posted May 30, 2014 good find, I didn't look on ebay. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted May 30, 2014 Share Posted May 30, 2014 I've just read right back through it. That's a defender PAS mount that's been butchered for some reason and bolted to the existing holes on the engine block. That strap is only there I think because the strength of the cast block has been lost by the butchering. The PAS should be driven by the crank and water pump, the alternator by the PAS. There's a long aluminium casting bolts to the side of the disco timing case, using the hole that strap is on amongst others, then the PAS is bolted to a steel plate 6mm thick which pivots on the front of it to tension the main belt, then the alternator swings above it. It looks like a half baked effort at converting a disco into a defender spec engine Quote Link to comment Share on other sites More sharing options...
western Posted May 30, 2014 Share Posted May 30, 2014 I was thinking it was a chopped about Defender mounting, certainly doesn't look like mine. a genuine defender 200tdi PAS/Alt bracket should bolt on, timing case has 2 bolts going in through the bracket from inside the pump recess. maybe Disco 200tdi doesn't have those.

benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 So if I bought a disco mount, that should fit the block properly? I can then fit the correct disco alternator. Presumably the pas pump should have a pulley on it with 2 grooves then, one to take the drive off the crank and one to drive the alternator. I wonder if this was done as a way of fitting the air filter where it was, I think with the alternator higher it may foul where the air filter was mounted before.

benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 It's a funny old conversion because I have a high turbo on it, as a defender should be, but it's definitely a 12L (Disco) engine. Quote Link to comment Share on other sites More sharing options...
western Posted May 30, 2014 Share Posted May 30, 2014 the correct bracket will sort the pump & aLternator location. PAS pump should have 1 groove, crank pulley should have 2 or 3 grooves. crank pulley front groove runs PAS pump only middle groove runs alternator & water pump inner groove runs air con compressor if fitted. see my pics below [Defender 200tdi] http://smg.photobucket.com/user/western214h/library/200Tdi%203%20groove%20pulley?sort=3&page=1 Quote Link to comment Share on other sites More sharing options...
benthegardener Posted May 30, 2014 Author Share Posted May 30, 2014 So is the belt system different between Disco and defender then? That sounds different to ejparrott said "The PAS should be driven by the crank and water pump, the alternator by the PAS." I would need to follow the disco belts wouldn't I, if they are different?

western Posted May 30, 2014 Share Posted May 30, 2014 So is the belt system different between Disco and defender then? That sounds different to I believe Yes, sounds like it's a bit of a bogged conversion, 12L is the Disco variant & it should have the air intake chamber & low mount turbo, someone has fitted a Defender manifold then if turbo is high up. not sure how the disco belts are routed.

ejparrott Posted May 31, 2014 Share Posted May 31, 2014 Disco 200 TDi has a single groove crank pulley unless its aircon model, then the PAS has a twin groove pulley. The alternator belt is behind the main belt. This is The 109 but it's in standard format 1 Quote Link to comment Share on other sites More sharing options...
PMike Posted February 16, 2021 Share Posted February 16, 2021 I think mine is totally butchered then, PAS bracket bolts snapped so almost no power steering, heating and battery charging. I found that this post is the most accurate for my current situation, don't really know where to start? I recently become owner of Defender 110 93 L plate with 12L engine which is Disco engine if I'm not wrong, alternator and PAS brackets arrangements just don't look right to me?? Should I look for second hand bracket ? or it wont help at all as turbo is high and manifolds may be on the way with original brackets? Please advise. I have 2 grooves on crank pulley and only one on PAS, picture for reference Quote Link to comment Share on other sites More sharing options...
92a Posted February 16, 2021 Share Posted February 16, 2021 The front timing case , manifolds etc are easily swapped between defender and discovery blocks the 12L refers to what it went in originally, post up some more pics or have a google or look on ebay to work out what timing case you have then you can get the right bits , Quote Link to comment Share on other sites More sharing options...
gruntus Posted February 16, 2021 Share Posted February 16, 2021 Hi PMike, Just for an additional reference point to work out what you have, this is a pic of my 200TDi Defender Engine (Turbo at the top) with PAS, Alt and water pump pulleys and belts shown at slightly different angles.

andy _1 Posted February 16, 2021 Share Posted February 16, 2021 (edited) I don't think its been butchered the mount that is, but it looks like your missing that large plate on mine and maybe that what all the washers were for. Mine is a discovery 200tdi complete fitted in a 1989 90 Edited February 16, 2021 by andy _1 1 Quote Link to comment Share on other sites More sharing options...
gruntus Posted February 16, 2021 Share Posted February 16, 2021 Pmike, my bottom pic is the clearest for the pas bracket (defender 200 engine) to compare against Andy 1s (disco 200 engine). In my view the disco bracket is superior for tensioning the PAS as the square hole that's visible is good for using a 1/2 drive to apply tension whilst you tighten the three bolts.

western Posted February 16, 2021 Share Posted February 16, 2021 200tdi defender spec PAS pump plate has a 1/2 square hole in it as well. Quote Link to comment Share on other sites More sharing options...
