Yes, the 4G69 has balance shafts. I wouldn't be surprised if the kit from a 4G63 fit. I haven't looked at the shop manual that close to compare the bearings and oil pump, but the blocks are *very* similar.

No, it doesn't. Their benefit is they balance out a little engine vibration. The drawback is they add rotating mass, complexity, oil usage, and the possibility for the balance shaft belt to break and take out the main valve timing belt.

The eliminator kit will have a stubby shaft to replace the shaft the oil pump gear is on, a cap to cover the front case hole where the other shaft was, and a set of bearings to install in the block to cover the oil holes the balance shafts used. That's pretty much it.

Unfortunately, installation requires removal of the front case, timing belt, crank pulley, pretty much everything on the front of the engine. Then you pull out the shafts, pull out the bearings, install the new bearings (or just turn your original bearings and install them so the oil holes DO NOT line up), put your oil pump gear on the stubby shaft, and put the front case back on the block. Plug the hole in the front case, and reassemble the rest of the parts you took off.

It's best to combine this with a timing belt change, since you're taking all that off anyway.

Engine removal required?

Hi there!

We just bought a lancer 2.4 4g69 wagon. It's got at this stage minor noise from balance shaft. It had apparently just had timing belt done but noise from timing case led me to get it inspected anyway. Balance shaft belt was too tight. They corrected and now original noise gone but new/previously unheard bearing noise coming from balance shaft.

My my question is: does installing a balance shaft removal kit require the removal of the actual shafts? And if so does the engine need to come out or can it be done in situ?

Mechanic said they can't be removed as one runs off oil pump and the engine has to come out. Sounds like this kit fixes that but just wondering why they didn't suggest it?

Otherwise bought a great car, gutsy manual wagon, low kms (98). Any advice appreciated. Sorry to drag up old post first up!

Cheers

Removing the balance shafts doesnt require removing the engine. You will just need to lower the engine side down enough to remove the front cover. One of the shafts will be attached to the oil pump, the other will have to be pulled from the block.

You can either leave the firewall side shaft in place to block the oil passages back there, simply remove the small timing belt from it. Or remove it and flip the bearings 180* to block the passages, and remove the shaft entirely.

As for the shaft attached to the oil pump. There is a stubby shaft from a 1.8l mirage that you can rebuild the oil pump with to remove the balance shaft. This process is required to remove the balance shafts. And is a lot of work, and likely why your mechanic said he wouldn't recommend it.

I've done this procedure 4 times now. I like it. Removes points of failure in the timing belt, it frees up rotating mass, and IMO is not noticeable as far as vibrations are concerned.

Thank you. Yeah I'm not keen to go to all that effort and the mechanic pretty much admitted that the labor would be in the 2-3 k mark. Whereas I Was quoted 3500 for a New engine.

I'm wondering if the mechanic installed the BS belt correctly now. Any tips on how to confirm that it's BS bearing noise and not something else?

Thanks for great advice. Cheers
