Hey.

Just had a crack at changing my timing belt on the rb25 and my crank pully keeps breaking f$(ckn cast jap crap pulleys.

I'm useing a three swinging finger type puller. never had trouble on cars with real pulleys lol these things are crap!!

Any suggestions in getting this thing off before my don't f$&k with me hammer comes out!

Tried to wd it tighten back up and lossen, hitting it with timber. Doing my head in. So much for my quick belt change.........

Yeh gotta do your research before pulling things apart and blaming the manufacturer when you do something wrong...

Nissan crank pulleys don't use the claw pullers. You use the two threaded holes on the front.

UNF is imperial not metric

Indeed. Metric is metric coarse and metric fine. Imperial is UNC and UNF. Glad this was here for me to read I'm doing my belt next year.

Just adding you the metric thing, thhere isn't just one fine option in metric, there's quite a few. If the pitch isn't specified it is always coarse. If it is a fine thread the pitch would be specified.

    • 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.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
