2G Oil Pump Sprocket Problem.

[dtaylor127]

Ok so I am new to working on my own vehicle and also to DSM's. I bought a 1995 Eclipse GSX 5 speed, knowing that the turbo was going out of the car. While I was driving it home I pushed in the clutch to downshift and that is when the car died. I got it back to my house the next day and took apart the Timing belt cover and also the lower cover to the timing belt. The "B" belt has broke and also the timing belt has had teeth chewed off of it. I have bought a "B" belt and also a new timing belt for my 4g63. I have put the new "B" belt on and also the new timing belt on today. I went to fire it up and all of the cranks turned and are in time but the OIL PUMP SPROCKET never moved while turning the key. Is there any way I would be able to fix this problem? I have heard that I can buy a Balance shaft eliminator kit that will not require the "B" belt anymore and also get rid of the Oil Pump Sprocket. I have all the special tools required to set the timing belt in time. In me purchasing the Balance Shaft Eliminator kit will it fix my problem of the Oil Pump Sprocket?

Sounds to me like the oil pump is frozen up and bad. Your best bet is to replace the whole pump assembly and while you are at it, check and make sure the head does not have any bent valves or you will have to tear it all apart again. When you do a balance shaft elimination kit in the motor, you will still have your oil pump sprocket due to the balance shaft being located behind a castle nut that is located above the oil pump sprocket.
So to answer your question quickly, no it will not fix the oil pump sprocket unless you buy a new oil pump unit.

I have both my intake and exhaust cranks on the top part of the timing belt set to top dead center with no problem. All the marks and everything are lined up where they are supposed to be. The only thing that I am experienceing problems with is the oil pump sprocket does not turn at all when trying to start my car. So I will have to buy a new oil pump kit?

So I am going to have to buy a whole new oil pump unit? What is this unit called? Is it just called OIL PUMP UNIT or is there a certain name?

O Btw this is the kit i bought for me BS elimination BALANCE SHAFT ELIMINATOR KIT ECLIPSE TALON TURBO 4G63 :eBay Motors (item 330371203773 end time Nov-23-09 20:06:21 PST)

So if I buy this kit it will replace the old parts from my oil pump sprocket and put these new ones in and it should all be ok?

When you had the timing belt off did you try turning the oil pump. And if infact when you have the engine in time an try to turn if over if the oil pump is not turning then you should see the belt jumping teeth on the sprocket. If the pump did lock up you need to find out why. Your friend who posted on here seems like he can help you so i would take that route if you have that option. Any questions pm me i have installed at least 5 of those pumps an know just about every issue there is.

Me and my buddy got my timing belt back on after having the old one having teeth torn off of it. We tried moving the oil pump sprocket by hand and it did not budge whatsoever. We put the timing belt on anyways since i have a 1 year warranty and tried turning it over and still nothing. The oil pump sprocket is seized up and we just need to figure out why it is not turning. Everything else is in time and turns when we went to start it. I just tapped it for a sec and let off when we went to start the car. So it would not damage anything just to test it out.

I'm might be mis-understanding something, but I don't see how you can have the timing belt installed with all the pulleys on time and the engine running or turning and the oil pump sproket be completely seized upat the same time....
Am I getting this wrong?

And No if you buy that kit it will only be so that you can eliminate the balance shafts, we don't know what is causing your oil pump sproket to be seized up. The pump inside gears may be seized or the balance shaft may be broken or the B.S bearings may have spun and siezed(not very likely).
I would take the oil pump assembly off and inspect it.
If you buy a BS eliminiator kit (especially from ebay) make sure the stubby shaft is a OEM Mits. one like the one on the pic "1995gsxawd" posted, it has to have the oil groove in the middle.. I've heard and read horror stories of the cheap stubby destroying itself and taking the pump with it.
If you don't buy an eliminator kit and decide to install a stock pump, make sure the oil pump sproket is timed correctly as it can spin 3 times before the B.S. can be on time with the rest of the engine.


Good Luck!

No I never said that we have the engine running... . I said that we have put everything on and everything was lined up BESIDES the oil pump sprocket. I jumped in the car and then went to turn it over and it made a sound but didn't since the oil pump sprocket is frozen up.

Did that explain a little bit better?
