tommyg Posted August 30, 2015 Author Share Posted August 30, 2015 OK - managed to get the wires on the terminal post and tight if I did not use the spring washer - used some tread lock instead - will this be ok? Link to comment Share on other sites More sharing options...
John Vine Posted August 30, 2015 Share Posted August 30, 2015 Are you saying you've stripped the thread on the big terminal post? If so, how much of the thread remains, and where (top or bottom of the post)? If there's still good thread at the top, you may get away with packing things out with washers. I wouldn't use threadlock as this will likely soften/fail due to heat. JV Link to comment Share on other sites More sharing options...
tommyg Posted August 30, 2015 Author Share Posted August 30, 2015 Yes - it is threaded at the top - I think due to me putting the nut on not straight (doh!). Therefore it is ok if I exclude the spring washer (ie there is enough thread left for the connectors and the nut, not if I include the washer). if I include this then there is not enought thread?Therefore, if not thread lock - any other ideas? thnkstom Link to comment Share on other sites More sharing options...
John Vine Posted August 30, 2015 Share Posted August 30, 2015 If you can get the nut tight enough without the washer, that should be fine. In fact, looking at my starter (R400D), there is no washer! Bear in mind that this terminal carries a big current (several hundred amps) so you want it to be electrically sound. If all else fails (and depending on the make/model of the starter), the solution is to get a new terminal post fitted to the solenoid housing. At worst, a new solenoid assembly will fix things.Noting your Tetbury location, did you get your kit from Millwood? If so, I'm sure Jon will help you out.JV Link to comment Share on other sites More sharing options...
tommyg Posted August 30, 2015 Author Share Posted August 30, 2015 Thanks JohnIt is good and tight - so I think I will see how it goes when it gets to start up.yes, I got from Millwood - Jon has been brilliant. cheerstom Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 31, 2015 Member Share Posted August 31, 2015 Sounds as if you're now OK. But possibilities in addition to the above: Recover some of the rogered thread with a die thread cutter. But that may need getting it out of the car, in which case you might be able to replace the post, and a specialist almost certainly could, as JV says. Fit a short male/ female adaptor (aka standoff) that can grab the remnant of the thread and give you a longer post.Jonathan Link to comment Share on other sites More sharing options...
Nigel Riches Posted August 31, 2015 Share Posted August 31, 2015 Fit self locking nut instead of the original, preferably not a nyloc type, these can relax and loosen due to the heat where the starter motor is fitted. Nigel Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted August 31, 2015 Member Share Posted August 31, 2015 Agreed.What's the shallowest locking nut that doesn't contain plastic?Jonathan Link to comment Share on other sites More sharing options...
Jim 123 Posted August 31, 2015 Share Posted August 31, 2015 If you can get the nut tight and holding the cable without a washer, can you get another nut to sit on the remaining thread on the terminal post? My thinking is that you might be able to get a gentle interference fit between the 2 nuts to prevent the nut that is taking the load from working free.Best of luck with your build. I'm not far from you (Cheltenham), if you need a spare pair of hands for anything, just let me know. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted August 31, 2015 Member Share Posted August 31, 2015 That's clever. You could also put some sort of locking washer on the wrong side of the ring terminal.Jonathan Link to comment Share on other sites More sharing options...
