ok will get it. thanks. from there is it fairly simple?

very simple.

Ask Your Own Mitsubishi Question

you may have to take the upper engine mount off so the engine drops enough to fit the tool on the harmonic balancer though Please note that customer satisfaction is my number one goal and rating this chat session 3 or more stars will be greatly appreciated and will allow any follow- up questions you may have. we can chat back and forth many times until your issue is taken care of.

another question, the is a small hole off center of the main one with what looks like a kotter pin/key does it need to removed before pulley will come off and if so how?

no that does not need to come off. that's a guide pin.

went and got a wheel puller but it came with no instructions and the drive shaft was too big to fit and couldn't make it work. is there different sizes of wheel pullers. i can pull the pulley but the gear directly behind it is trying to come out with it

crankshaft gear is trying to come off with it?

that it what it seems like

does it have a small pin sticking out of the front of the balancer?

Ask Your Own Mitsubishi Question

ill be back on in a bit. I have to get to my shop

Ask Your Own Mitsubishi Question
Customer reply replied 5 months ago
no other bolts besides the main one

ok this is what keep the crank gear attached, usually, it is protruded out and you pull it out. when you said there was a pin I thought you were talking about the keyway lock.

any ideas on how to get it off?

Customer reply replied 5 months ago
i have now got a puller on it and the puller was getting it to the point of trying to pull the timingbelt and everything out with it. I have tried to hit with hammer to break loose. it is one with the crank!

ok, Im going to opt out and let someone else chime in here. it is not one piece

Are you trying to replace the oil seal behind?

Ask Your Own Mitsubishi Question
Customer reply replied 5 months ago
no, just trying to replace crankshaft pulley/harmonic balancer. cannot get the old one free from the timing gear. the entire gear is trying to come out with pulley

unfortunately the pulley IS one piece with timing belt pulley, so you have to remove timing belt before pulling that off.

Ask Your Own Mitsubishi Question
Customer reply replied 5 months ago
on all diagrams and new part that is not what I can find

if you like, I can forward you the procedure for replacing the timing belt. If you want that, I would need the VIN#

Ask Your Own Mitsubishi Question

The ones that I have done have been that way, with the one piece pulley.

Vin # is 4A3AC54H61E143125 2001 Mitsubishi Eclipse GT 3.0 V6.
Customer reply replied 5 months ago
I have the Haynes manual and it shows it as two separate parts but this manual is kind of hit and miss on some subjects

OK....I thought u had a 2.4 4 cylinder. The V6 is 2 separate pieces. Let me look at the removal procedure.

Ask Your Own Mitsubishi Question

Wow, it looks as though once you get that center bolt out of balancer that it should just pull out of there. It may have rust/corrosion build up that is freezing it together or the crank alignment key has become distorted. Either way, it may require heating the crank pulley carefully with a propane torch and then shocking it with a hammer blow to free it. Just be careful not to heat pulley so hot that it damages timing belt. Also avoid hitting pulley on the v groove for the belt.

I got it out!!! just took a torch and hammer to it and beat it off. I have the next issue unfortunately, I think I might have damaged the threads, when trying to put the bolt back in it wouldn't catch and after wards the bolt threads are shown in picture attached

If you take a sharp pick, u may be able to peel that metal from those top threads. Sometimes, a thread file may be needed. U can get one at a hardware store or harbor freight store. Also a wire brush or wire wheel can remove that metal from the threads at times. When you do re-install the bolt you may want to put some thread - locker on bolt. Also, tap pulley on further before trying to pull it on with threaded bolt so that it engages alot of threads before torque is applied so that it doesnt happen again. Good Luck!
