Hey All,

I think i need some tips/tricks, help or something..

Im changing the timing belt (rb26) atm while the engine is on my engine stand.

I have the flywheel bolts wedged into the stand with a shifter, and a breaker bar on the harmonic balancer bolt giving it all my might and bodyweight. Bent the shifter.....

Ok so i wedged a breakerbar instead of a shifter and used the air compressor(only 2hp) with a impact drill won't budge AT ALL.

Went back to the breaker bar and an extension, gave it some allmighty heaves and bent the breaker bar wedged in the flywheel.

I cannot get the dam bolt to budge even a millimeter...

Any ideas, tips/tricks? its really starting to annoy me.

hey man.

Try this one at your own risk...

put ur car down on four wheels... if youve jacked it up.

Put in the breaker bar, but put the breaker bar on an angle so its wedged/leaning onto the ground. Turn the engine over for a spilt second. Should give it enough turn to loosen the nut. make sure its facing the right way so ur loosening it not tightening it even more.

THere should be enough power from turning the engine over to loosen it.

However its quite risky doing this... so please do this as a last resort... and be careful!!!

EDIT: oops i didnt realise ur engine is on a stand... i dont think this tip will work =/. sorry dude =(

Had same problem on another car, luckily for me i sourced a 1inch rattle gun. Try using a hammer and punch/float bar and hit the bolt to try 'shock' the sized bolt. then give the gun another go. No go? try sourcing a bigger gun, but try not to snap the bolt...haha, that would suck.

engine is on a stand so I don't think the starter motor trick will work too well.

Unless you have access to a good compressor and big rattle gun, the old fashioned way is the way to do it. With enough leverage you can undo anything.

flywheel bolts (make sure they are at least 1cm into the crank) and a strong enough bar will brace it. Then put an extension on the end of the breaker bar and off you go. those round galvanised fence posts make a great extension. You probably want to use a fairly short breaker bar is it will be stronger so just put a bigger bar over a short breaker bar.

Also, as well as encouraging it with a tap on the bolt's nose, you could also give it a quick tighten as well. If you can move it a fraction you will break the 15yo seal, then go back to loosening

Well,

that was one stubborn pulley bolt to say the least!

Called a good mate that owns a workshop and got the biggest dam impact wrench i have ever seen!

Still took a good minute or two drilling away, but got the bastard in the end!

*NOTE TO ALL!*

GET THE BIGGEST IMAPCT WRENCH POSSIBLE

thanks for the help guys!

Hehe I was going to say use an electric, industrial strength impact gun (shits all over air tools). After 2 days of pulling and wiggling, less than a second with the gun and bang off she came. Same gun sheared all my diff bolts straight out of my old BW78 series diff!

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
