| Warrenm:
This is the 1st project that I've posted up here, so here it goes. As the title says, it's an adapter to fit a balancer to a 6 cylinder 202 Holden engine. As it is an Australian GM engine & the balancer is made in the USA, they don't make an adapter to fit this application. I purchased a piece of steel, 4"long , 4"diameter, which ended up being 4140(but I was only charged for "Bright" steel :thumbup:. This is what it looked like at the start. |

This is an inline 6 that has all the usual balance issues you get when you start to spin them over 7000rpm. The only balancers that are available to suit this engine are the std type, that are not heavy enough, or one made by Romac which is heavier, but still not heavy enough. Now for an update. The 4140 is an Australian standard, the British standard is BS970-1955 EN19A. A plan of what the finished article should look like & some progress on the lathe. |

No David they don't make an 'adapter' for this application but they do make several balancers which is why i asked. I have built several of these engines and have always found the ones availible in Australia to be sufficent. Warrenm is it a red, blue or black ?? Red i can understand adapting a larger balancer but I usually retro fit a blue crank due to them having better counterweights. Also if your going the supercharged route fit a second key to the crank :ddb: |
