go to bunnings and buy a benzo torch and gently warm up the gear and slide it off. Wont take much but Jesus christ you need to be careful doing it as to not heat the crank. They usually come off easy as

Once the cog is heated up do you just remove the gear off the shaft by hand or you still need some assistance?

ok no succes yet, I have drilled and taped the gear and used 6mm bolts on a stanley sterring pulley.. anyway i bent the stanly stearing puller.. so i grabbed a flat pri bar spent an hour dilling that out and used that as a make shift puller.. bent that aswell untill i stripped the thread i had mad in the cog. During this process i was heating up and cooling the crank shaft see if that will bude (just used a butane torch).. Running out of ideas. anyone had succes cutting these off... Is there a mobile sevice that specialise in this stuff?

Thoughts ideas.. ?

No not realy defelecting the heat, was just running the water on it peridoicaly to try and drop the tempertature on the shaft/

This is not the best idea, rapid heat/cold changes will weaken parts. Not a problem with the crank gear but not really a good thing on your crankshaft. your better off heating it, then letting it cool on its own without any help from water etc

have u tried hitting it back toward the engine just to crack it first ? this is what i did. then lubed with inox and pryed forward against the oil pump with a flat head screw driver one either side. also with a flat head and hammer try rotational wise to help crack it more. once u get it far enough forward u can use the puller. u just need a big jolt to crack it then youre laughin.

I mange to remove it finally, I drilled just above the keyway than used my ozito ripp off dremel to cut a thin cut just above the keyway, used a cold chisel to crack it a little and used my pulley and the 6mm tapped holes i made to slip it off. Wow this thing was epic rusted on glad its off now.

Now here a question is there something i can put on the shaft to prevent this happening again?

Sounds familliar, mine was nicely rusted on too.

You can get anti-seize to put on it, i think you can get little tubes and you should be able to find it at a fastener or engineering supplies shop.

      Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.

      Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.

      OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
