hey all.. this is in ref to a CA18DET but its only really general info I need.

ok we're at the point of removing the crankshaft sprocket & backing plate to replace a seal.. as seen here tho it's not my engine..

Using a screwdriver, wd40 etc and trying to lever it off but it's just NOT coming off & Mic's about to pop a vein or something.. rusted on perhaps? I don't know.. Need ideas :)

(yes it's lined up with the notch thingy/tooth in the middle)

[oil seals are sorted]

Any advice/ideas appreciated.

Was hoping to put the head back on today :)

Thanks guys!!

OK still need help here.. tho the oil seals are sorted now.

Used a blow torch but the crankshaft sprocket is still on there, barely moved. Last option atm is to drill it and crack it off unless someone has a better suggestion!

Where are all the wonderful people who normally know more than me?! I am a girl you know and at least I've come up with some ideas!

More heat should do the trick, other than that you may have to destroy it and buy a new one. I usualy get them off with the oxy torch though, just apply heat on the gear only .

More heat is the easiest solution, but there's a seal for the oil pump behind the sprocket and it would be a very good idea (IMHO mandatory) to replace the seal after applying heat to the area. Also that thin plate you can see behind the sprocket is a guide for the cam belt....try not to damage it and also try not to use the oil pump housing as a levering point.

If heat doesn't work, cutting slots in the sprocket with an angle driver then using a cold chisel to split it is a last resort. Make sure you can get a replacement before destroying it first tho. In a couple of cases I've drilled and tapped holes in the sprocket then used a home-made puller to get it off, but that can only normally be done with the engine out, unless you have access to an air drill.

Good Luck

    • He obviously had his reason for flipping you off. I wonder what it was...
    • Thats why I stay far, far away from Eastwood. only go there if I wanna eat Korean food 
    • I have to agree like, yesterday, I was driving down the warringah freeway towards the bridge when this jackass driving a beaten up Honda civic cut me off so suddenly it made me almost yank the wheel to avoid him hitting my car. Honestly and he had the NERVE to flip me off (or some other gesture Idk). Im a calm guy, but really some people just dont deserve to have a license, let alone be allowed to drive on densely populated roads/highways. If youre gonna cut through lanes at least use the damn turn signal
    • HPA do an interesting video on tuning, and Adrian shows on the dyno, moving from 10:1 to 12:1 (And I think even 13:1) and the power moves SFA. However, a couple of degrees of timing has a HUGE impact. Exhaust side of things will more be the length of the exhaust and how many bends and turns you have. The straighter you can keep it, the better. By a lot. Oh, and getting the diameter right. Bigger isn't always better. Going to big can actually lose you power.
    • I have to say, most people I see on the road fit the bill of atrocious drivers. Whether they be cowboys in their dual cabs, bogans in the Commodores, or the soccer mums. Pretty much most people on the road put zero freaking thought into driving. Barely look further up the road then the end of their bonnet, and have never even thought about how catastrophically wrong shit can go, by doing what they all deem as normal driving. Especially their late braking, racing to stopped lights, and sitting half a foot off the bumper of the car in front at 110km/h. Wanna know what's even better? By the time their kids get to be old enough to learn to drive, they've already got in the back of their brain what is normal driving, how annoyed you're allowed to get at people etc, and then their parents who actually have zero freaking skill at driving (Even though they constantly say "I've been driving for 20 years and never had an accident!") teach the little twerps how to drive, or should I say, how to make a car move. Literally watched a parent teach their L Plater, on a 4 lane freeway, that you just slam the brakes on, and push your way over, even with a B Double bearing down on you, and that's how you should drive, rather then, just keep going to the next exit. Same shit happens all the time for side streets etc, watching numpties pull dumb shit turns pushing across 3 lanes of traffic, rather than just go up the road another 30 seconds, and take the next turn that'll get you to the same location... Oh, and the damn right lane bandits. Or the retards driving along with their headphones in, and can't hear the ambulance or fire truck right up their ass about to run them over...   Pretty much, people drive on the road, like ego centric f**ks, and don't actually think how dumb shit their driving is, how it could easily kill them or someone else in a split second, or at the very least, how they're driving is contributing to all the shit they're bitching about on the road, like shitty congestion!
