HOW TO: Install Cosworth Balance Shaft Delete Kit with Pictures

[Egz]

Your answer is right above you. The 2.0 does not have a balance shaft to delete.

When i did mine it is very easy to pray the pan off in front of the engine.

yeah the oil pan and filter are definately a very nice blessing over some cars thats for sure. No exhaust, axles, or anything else to get in the way. Its so nice.

[craigst89]

thats pretty cool but are there any long term downsides or anyway this can damage your engine?

[jetrinka]

Well as far as reliability of the motor I wouldn't think so. It was put in to purely cancel out vibrations that would transfer into the cabin. As far as longevity of other things such as interior panels and all around quiet I would think it would deteriorate those things faster resulting in more rattles and such developing.

I too have wondered this though. I have never seen one in person and no picture really does it justice so I can't say whether or not it really has any effect in actually balancing and components in the motor. I mean lets put it this way. If the motor and things in it are that unbalanced to begin with then you have a serious problem anyway.

Now having the BS in my car for 2 weeks and its my DD, I have noticed alittle bit of more vibration but nothing to serioous that it doesnt worry me. In the 2000 to 3000 rpm range when accelerating slow you can feel it alittle. When crusing or WOT in between those RPMs its fine. When idleing you can feel it sometimes if your feeling/listing to the vibrations.


Its a $30 mod that gets rid of atleast 15 pounds. Why not.

I think it's 18-point-something lbs.

The only issues of removing the balance shafts (yes, there should be two in the housing) is that it will void your warranty (but they would have to take the pan off to even know), you may not like the vibration (but your girlfriend will), your engine mounts may wear faster (but probably not so much), and you'll have to use more of that expensive oil. If you remove it, I recommend using the oil sump baffle at focussport.com to ensure your oil pickup stays submerged during cornering and stopping/accelerating.

Aftermarket Internals (Pistons, Rods, Crank Shaft)
If you plan on upgrading the internals, removing the balance shafts is a must. Of course you would do this anyway if you are in the block, but dont put it back in. The balance shafts will actually increase vibrations and crank bearing wear if components of weights other than the stock design are used. You would have a better chance of winning the lottery than having the balance shafts phased correctly after changing weights of these components.

Stock Internals
If you are using stock internals, which most of you probably are, and are concerned about additional engine wear, know that the balance shafts do nothing to help "primary balance", and only deal with "secondary balance". Therefore, there will be no effect on crank thrash. These three links should tell you everything you need to know about balance and balance shafts. The third is most specific to most of your concerns.
