i wouldn't say no straight away, dpends if you are a highly qualfied engineer and know what your doing. I know people who balance there own cranks. "Cars are a lifetime of pain" |

i have watched a crank and flywheel being balanced at home, a jig was made to support the crank using skateboard bearings, holding up the crank/flywheel assembly around the main bearings so it can spin very freely, it was then spun, when it stopped a marker was used to mark the very bottom, spun again marked and again 3 or 4 times you should be marking the same spot every time if you are its heaviest at that spot and a small amount of metal removed

The process described above is perfectly feasible, BUT, it is static balancing only.

I knew, I just knew that there would be some one out there who thinks its perfectly satisfactory to have 'balanced' a crank/ flywheel at home, with a Black & Decker and a needle file Edited by Sprocket on 9th Jan, 2009. On 26th Oct, 2004 TurboDave16v said:

Get it done properly (dynamic balance) or leave it alone.

although the penny has just dropped and i now know the difference between dynamic and static balancing, i though dynamic balancing was the (fly/crank/rods/pistons) being "staticaly balanced"

tbh a 998 a+ block/rods/pistons might be the fastest and cheepest option, i have not seen a 998 crank on its own for a long time but you cant give the blocks away, well actually you can lol wil took care of mine :)

I have a spare 998 A+ crank. It needs a regrind but otherwise OK.

Autos are a good source for parts! they run huge big oil filters as standard the thrusts are usually perfect and autos arnt usually thrashed the same way as a manual with a 17 year old behind the wheel! That mini is determined to Kill me!!!! |

Interesting point. I've overheard conversations about "home machining" of cranks and rods. Like wedging your own crankshaft with an angle grinder. Obviously, it takes an immense amount of marking, measurement and balancing via many means.
Bugger off, I'm getting there. |

Obviously, it takes an immense amount of marking, measurement and balancing via many means. I gather components can be quite out of whack for starters. I'm not sure to what degree. You should be able to get it pretty accurate though. I wouldn't use a crank modded in this manner! As Rod said though you can only achieve static balancing by these methods.

you can do anything on the cheap if you try but to what end? ballancing as above will work but to what accuracy.

Even if a crank is statically balanced it will remove the surface hardening in the relieved areas. Therefore, it will require re-hardening afterwards by professionals and it still won't be balanced dynamically. So anybody thinking of DIY balancing, stop being a miserly fuck and get it done professionally. DIY will always be a compromise On 12th Nov, 2009 Paul S said:

DIY will always be a compromise my friend works for an aircraft engine company and he was going to balance my turbo on the machine at work. what i was getting at is even with the right tools you still have to know what to work to otherwise your best of getting it done properly |
