Bob Simon Posted March 29, 2009 Share Posted March 29, 2009 I need to source a XE Cam belt infill plate. Swindon used to do one, but only for non-LN cam belt paths. I think the same goes for Spiess. My engine is LN. Anyone? -Bob 94 HPC VX Evo III Link to comment Share on other sites More sharing options...
Garibaldi Posted March 30, 2009 Share Posted March 30, 2009 Bob As far as I know the only belt and pulley layout for the XE stone guards is the pre LN.... BUT The stone guard I have is part of a Speiss kit and is sized around the smaller LN Vernier pulleys but uses a pre LN idler layout with a custom belt length to suite (no tensioner etc)... the alloy water pump pulley has LN tooth profiles also.... the 2X large diameter metal idlers needed come from SBD Aves was selling a complete Swindon setup a month or so ago... you just need the belt... do a 2 month search in for sale for Swindon XE and just check the tooth profiles..

Swiss Tony Posted March 30, 2009 Share Posted March 30, 2009 There is one on ebay at the moment (with some other bits). Ends tonight. Search under Swindon Link to comment Share on other sites More sharing options...
Bob Simon Posted March 30, 2009 Author Share Posted March 30, 2009 Thanks for the tips. I really would like to keep the LN belt train intact if possible. I've already invested in new LN cam pulleys, alloy idlers, belt, etc. Time to buy a chunk of acetal or nylon and craft one from scratch I guess. -Bob 94 HPC VX Evo III Link to comment Share on other sites More sharing options...
Harry Flatters Posted March 31, 2009 Share Posted March 31, 2009 Bob, I have an LN XE with a Spiess cam belt insert. Problem is, I believe they have stopped making the kit of parts now. I can tell you that not only do you have to alter the belt path to fit the thing using new metal pulleys from SBD but there is also a fair amont of fettling (spacing the pulleys and nib roller correctly etc) that has to be done as well. You also have to replace the standard water pump pulley, this came from Spiess. One final thing, the cam belts (from Spiess) are a different length to the standard GM part. Doh - duplicate information to Garibaldi's post, but you get the picture If you do manage to get hold of a Spiess set, I can send you details/pics of my installation. *arrowright*Harry Flatters *arrowright* AKA Steve Mell - Su77on Se7ener Edited by - Harry Flatters on 31 Mar 2009 08:57:40 Link to comment Share on other sites More sharing options...
ECR Posted March 31, 2009 Share Posted March 31, 2009 Steve You have to replace the standard water pump pulley ? Do you extract the old one from the shaft and press on a new one ? I ask because I tried doing just that (as an experiment) on an old pump and it seemed immovable ... (Or was I trying to dismantle the pump - I forget ) Or do you buy a new pump from Spiess with the pulley already fitted Just interested ...

Garibaldi Posted April 2, 2009 Share Posted April 2, 2009 Roger I bought the alloy pump pully from Spiess and it was fitted by Rob at Protune when my car last had some head work done... so in answer to your question, though I did not do it myself, it can be done...

Harry Flatters Posted April 2, 2009 Share Posted April 2, 2009 Roger, sorry for the delay. Yes, Spiess supplied the new pulley and we had to use a hydraulic press to remove the old one and likewise to press the new one on. Bloody tight it was too. I think the problem with the original pulley is the belt retaining flanges (can I say flange before 11:00 ) front and rear. I think the Spiess solution requires the belt to 'float' on the water pump rather like it does on the vernier pulleys. *arrowright*Harry Flatters *arrowright* AKA Steve Mell - Su77on Se7ener Link to comment Share on other sites More sharing options...
