mcerbm Posted February 19, 2017 Share Posted February 19, 2017 Looking in my engine bay I found to my surprise that the adjustment bracket for the alternator was floating in free space./sites/default/files/images/users/1260/large_IMG_2094.jpgDoes anyone know what part / spacer / fasteners should go here?Luckily the bracket holding the alternator was pretty stiff keeping the tension in the belt.

revilla Posted February 19, 2017 Share Posted February 19, 2017 First of all, check the bolt hasn't sheared off in the block ... it's a surprisingly common failure, I've seen three of them fail like that.The spacer comes as part of the "Link Adjuster" - if it's an EU3 engine it will be YLX100141 - I'm not sure if EU2 engines used the same part and it's hard to see in your picture, I know very early ones used a Metro alternator arrangement but I think the spacer bush part should be the same.They are surprisingly expensive (£32 from Rimmer) and hard to come by used. They do occasionally pop up on eBay. Several places do sell an "upgraded" version like this but it's still not a cheap fix.If you're stuck for getting hold of one, I've got a used one in my spares box you can have for £10. It's not the shiniest but it will do the job. Send me a BM if you want it. Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted February 19, 2017 Area Representative Share Posted February 19, 2017 I also lost my bolt some time ago. Rimmer Bros are another alternative for the standard part or you could upgrade to this. Much easier to adjust than the original item.Edited to say I must type quicker. Also you can always get one at your local scrapyard. Link to comment Share on other sites More sharing options...
mcerbm Posted February 19, 2017 Author Share Posted February 19, 2017 I dont have the engine just now its out of the car and getting work done but i'm pretty sure it wasnt a sheared bolt from memory. The link adjuster I have just has a hole where the spacer should be, presumably the bolt vibrated free and the spacer went with it.my car is EU2 and the link just looks like thishttps://caterhamparts.co.uk/alternators/1333-alternator-tensioner-rover.html?search_query=alternator&results=53 Link to comment Share on other sites More sharing options...
mcerbm Posted February 19, 2017 Author Share Posted February 19, 2017 I think I will just go for the upgraded unit on ebay that Paul mentioned, must be much easier to gradually increase tension.Thanks for the help. Any tips on how to know what the correct tension should be when I come to re-fit. Link to comment Share on other sites More sharing options...
Area Representative Richard Price Posted February 19, 2017 Area Representative Share Posted February 19, 2017 Why not replace the spacer with enough 10mm washers to fill the gap, and simply use an M10 bolt of an appropriate length? Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 19, 2017 Share Posted February 19, 2017 My engine is out (till tues) do you want me to wip it off and measure it - 5 mins for someone with a lathe to make a spacer.Let me know soon!Ian Link to comment Share on other sites More sharing options...
Area Representative Paul Richards Posted February 19, 2017 Area Representative Share Posted February 19, 2017 Correct tension. I usually twist along the longest length. If you can twist through 90 degrees then it's about right. If it's took slack it will soon squeal when under load. Link to comment Share on other sites More sharing options...
mcerbm Posted February 19, 2017 Author Share Posted February 19, 2017 hi everyone, thanks for the suggestions, I ordered the turnbuckle style mount off ebay that Paul suggested Link to comment Share on other sites More sharing options...
John Vine Posted February 20, 2017 Share Posted February 20, 2017 ... i'm pretty sure it wasnt a sheared bolt from memory....Do check that there's not a piece of bolt lurking down the threaded hole. The retaining bolt on my old EU2 SS-R sheared off about 10mm below the surface.JV Link to comment Share on other sites More sharing options...
mcerbm Posted February 20, 2017 Author Share Posted February 20, 2017 ok thanks John, will do when the engine is back. Link to comment Share on other sites More sharing options...
