r16 air cleaner assembly wing nuts/bolts
Are the bolts (the ones that the wing nuts attach to to hold the cover) replaceable?
Mine are stripped, and the bolts themselves turn around a lot in their little "housing" - looks like maybe they were tack welded and the weld came undone? I'd just try to re-tack it, but since the threads are also stripped in places, just checking to see if there's an easy way to replace them, or if I need a new assembly.

You can replace them. I went to the hardware store and got replacement bolts. I cut out the old, stripped studs and welded the new in their place. I used slightly longer bolts so that I can run the reusable Spectre air filter listed in the Techwiki. Works perfectly.

Re: r16 air cleaner assembly wing nuts/bolts
Anyone come up with another or better idea for stripped bolts? I don't have a welder nor do I play a welder on TV.
Thanks.
Thanks.

Just arm-chairing a solution…but you could cut the stud short, clean-up the threads with a die, and use a threaded hex coupling to thread on a new chunk of threaded rod.

Re: r16 air cleaner assembly wing nuts/bolts
Nice thought, but most of the thread extends past the air filter cover. The cover would not slide over the coupling nut. It also doesn't solve the problem of the bolt spinning.GeoffM wrote: Sun Aug 04, 2024 5:21 pm Just arm-chairing a solution…but you could cut the stud short, clean-up the threads with a die, and use a threaded hex coupling to thread on a new chunk of threaded rod.

I couldn’t remember how long the stud was. But thinking more about it, yeah.ppeters914 wrote: Sun Aug 04, 2024 5:37 pmNice thought, but most of the thread extends past the air filter cover.

Re: r16 air cleaner assembly wing nuts/bolts
Dis regard if mentioned, but I didn't see any mention of just trying to repair what you have rather than replacing....Wouldn't the easiest solution be just re-tapping the threads on the bolts and nuts? Are the threads on the rod that far gone? I have been able to revive a number of bolts, nuts and threaded holes along the way without having to replace the original hardware.

Re: r16 air cleaner assembly wing nuts/bolts
The problem is not just the threads. The bolt heads have become rounded or something, which allows the bolt to spin. This makes it near impossible to fix the threads and/or screw on the wingnuts.Stick wrote: Mon Aug 05, 2024 6:08 am Dis regard if mentioned, but I didn't see any mention of just trying to repair what you have rather than replacing....Wouldn't the easiest solution be just re-tapping the threads on the bolts and nuts?
