I posted this in another thread but...

OK so how do i get the Crank timing pulley off then. NOT the Crank pulley, the one behind them, in front of the oil pump which the timing belt goes around. Does it come off with the oil pump, cos it seems that the pump is free from the block, but the timing pulley is stopping it and i dunno how to get that off.

Your help is appreciated.

Hi Bl4cK32 , use a screw driver with the blade on the inside of the pulley grooves, hit the head of the screw driver with the plastic hammer. Three or four places around the circumference are accessible, give each a tap or two. One clockwise and one anticlockwise, that usually works.

If not, the puller style you need has 3 arms with hooks on the end which go behind the pulley. The screw butts up to the front on the crankshaft, so as you wind it, the claws pull the pulley forward off the crank.

Tapping usually works, but occasionally you get a stubborn one that needs the puller.

Hope that clarifies

Hi armbrush, this seems to be happening more often than it used to. We had one in the machine shop last week that we had to cut into 3 pieces with the angle grinder to get it off the crank. The good news is if you have to break the pulley they are pretty cheap to buy.

I can't really add any more than I have, they usually come off with a few taps of the hammer. Stubborn ones we use a puller on and if it gets really bad we cut them off, but I have only had to do that a couple of times.

This is the type of puller we use;

This is a US supplier, if you print the picture out and take it to your local Repco they will have one.

I hope that is of some help.

Usually a lot of crap and some rust forms between the crank and the fitting (cam belt drive or harmonic balancer) so spray in plenty of lubricant and wiggle and turn and assist with the screwdriver. Done a few in the last month.

If you have the engine out this is a lot easier, but if it is in, and you are trying to remove the oil pump, you have to drop the sump as the oil pump has a big bolt head that protrudes from the bottom and catches on the sump. Found this out doing a quick front oil seal replacement that wasn't so quick.

For replacement seals for the oil pump and the cams, the RB30 front crank seal is choice and cheap and is at REPCO.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
