Zed Head Posted January 10, 2023 Share #325 Posted January 10, 2023 Don't overlook that application specific gland nuts are supplied with the replacement shocks, of all brands. The original Nissan gland nuts were meant to thread all the way down in to the strut tube and seal against the tube and the shaft to keep the oil in. The replacement gland nuts are meant to center and clamp the new self-contained shock in to the strut tube. The strut tubes themselves were not manufactured to accept a shock seating against the bottom where the welds are. In a way it's just blind luck that so many of them have fit well. Not a surprise that some finessing is needed in certain cases.

JagoBlitz Posted January 10, 2023 Share #326 Posted January 10, 2023 I used the gland nuts supplied by Koni. Link to comment https://www.classiczcars.com/topic/61542-koni-sports-for-classic-zs/?page=28#findComment-649185 Share on other sites More sharing options...
Zed Head Posted January 10, 2023 Share #327 Posted January 10, 2023 madkaw has posted about having to grind the welds at the bottom of the strut tube. I think it's in this thread, way back.

JagoBlitz Posted January 10, 2023 Share #329 Posted January 10, 2023 It's a different problem. I have the same issue like av8ferg described here: https://www.classiczcars.com/forums/topic/61542-koni-sports-for-classic-zs/?page=12#comment-628560 https://www.classiczcars.com/forums/topic/61542-koni-sports-for-classic-zs/?page=12#comment-628872 I am already in contact with MSA - I will disassemble everything tomorrow and get measurements so that we can find out if either the thread on the strut or the gland nut are out of spec.

JagoBlitz Posted January 26, 2023 Share #330 Posted January 26, 2023 Just FYI. I had two wrong gland nuts in the package. M52 was required, but they were only M51. Without the damper centering the gland nut, it was a very loose fit and the nut popped out at around 50Nm. The outer diameter of the gland nuts should be around 51.80mm to work correctly. 1 Link to comment https://www.classiczcars.com/topic/61542-koni-sports-for-classic-zs/?page=28#findComment-649700 Share on other sites More sharing options...
Zed Head Posted January 26, 2023 Share #331 Posted January 26, 2023 You're saying that the problem is fixed now? Did you order the wrong product or did the wrong nuts get put in your package?

Dr. 240Z Posted October 12, 2024 Share #333 Posted October 12, 2024 As there hasn't been a new post on Koni struts for some time, I'm hoping to get help. As is, I'm attempting to install new Koni struts (model; 23-1031 KONI Struts) on my Series I. The struts were back ordered and arrived in July. Fast forward, the new struts (yellow) are a little too long to fit as they should. I have spoken with 'Dave' at 'Motorsport Auto - The Z Store' the supplier, and he assured me that they sent the correct struts. Anyone else in this situation? Just wondering if the bolt at the bottom of the housing could be safely ground down without creating potential damage. Suggestions are welcomed...Thanks Link to comment https://www.classiczcars.com/topic/61542-koni-sports-for-classic-zs/?page=28#findComment-670160 Share on other sites More sharing options...
khughes Posted October 12, 2024 Share #334 Posted October 12, 2024 Yep, I went through that issue on an early Z.. see above.. after carefully grounding down the bottom nub on the struts.. they worked for me!

jfa.series1 Posted October 12, 2024 Share #335 Posted October 12, 2024 (edited) This is not a new problem, any number of owners of early cars experienced the same issue, myself included. The problems lies with a thick weld bead at the bottom of the strut tube that prevents the KONI insert from fully seating. The problem is visible when the gland nut will not install to the correct depth. KONI and MSA worked on a solution in the form of revised gland nuts with a longer thread body. MSA supplied these modified gland nuts at no cost to customers reporting the problem. I recommend you reconnect with MSA and request the modified gland nuts. BTW, the problem seemed to be limited to the front struts as there were no reports of rear struts having the issue.

Suppsoedly there was a note on the MSA pages about it but I don't see it. You might contact Jospeh or Koni Lee since they were in the conversation. @Joseph@TheZStore @KONI Lee https://www.thezstore.com/product/4296/koni-sport-adjustable-gas-strut-rear-70-8-74-240z-260z-coupe 1 Link to comment https://www.classiczcars.com/topic/61542-koni-sports-for-classic-zs/?page=28#findComment-670163 Share on other sites More sharing options...
