Header bolts {keeping them tight?}

boosted

Registered
How do you'all keep your header tight. I realize a turbo is like a heavy pendelum and also the turbo header gets extremely hot, but my last bike had a major problem becoming loose. Possibly a thicker flange, locktight, safety wiring bolts, etc. Any other suggestions? And have any of you had issues with this.
 
mine worked loose also, after talking to rcc you just have to tighten the **** out of them, richard said with an inch of threads you can tighten it until the flange bends.
 
We found that using studs (w/loctite) with self locking nuts worked the best (no nylon please), I used lockwashers on a couple units but they were only good for one use (my cheap washers went flat)

if they go on a stay on, well...how many times do you normally need to remove them?
Soo... A dab of weld should do da trick right Gar?

Most of the hardware around exh temps seems to work its way loose after a few heat cycles...If you check it a after a few hours or runs whatever the case may be...are they usually loose?

I have had good results with studs and a nut vs. a bolt...if there is room to work with.

One more thing to check over winter months.
 
Has very little if anything to do with "off and on"

if/when racing, turbo manifolds working loose are a serious problem due to heat. As the gases are superheated they can saw an exhaust port open in just a few seconds under full boost conditions. A regular exhaust manifold leak is a bit noisy, and annoying, just not the case with turbo motor..

The correct studs are physically stronger than bolts for attachment and with AN washers using a swedged locknut, manifold leaks are pretty much forgotten.. The few bucks for a set of studs and the work to install them can save the cost of having to weld a $3000 cylinder head and repair the thing. Pressure leaks are just a good thing to avoid.
 
place here local has what they call some sort of euro washer...teeth on both sides and you use them as a pair so they lock together. Supplier was very confident about these and exhaust bolts...might give them a try.

here's the place I deal with locally, always a ton of ss on hand.

I hafta call so they have my order ready....I like to wander around in these types of toy stores.
 
I'm on the hunt myself for exhaust studs and good washers/bolt combo.

just take one of your existing exhaust bolts down to your local "nut/bolt shop"

Keep in mind that you need "longer" by at least the height of 3 nuts if not 4. The bolt if the head was cut off would end up flush, you need to provide room for the nut, washer and the stud will also sink into the head a bit further..

Best to get them on the long side, install and trim them to length if you can not find one of the performance guys here with sets already made..

Example of what you are looking for... My guess is you could find the correct ones in that list... VW also had a nice self locking nut for their pipes, not sure it is the right size however..
 
Don't have one handy to measure. Maybe someone has the exhaust bolt removed as to get a rough measurement.

Found a pic of the nuts I was talking about... saves the headache of juggling washers, nuts etc in tight quarters..

I have a PM into Jay at APE. Will see if he offers a solution.

Those look like they would hold.
