Default Re: Engine balance during install

Thanks for sharing your experiences everyone. It's really helpful to a guy who is trying to put together a tool for a job he hasn't done before!

Sounds like a good approach, Rich. I'm aiming to get it as balanced as possible, but expect that some amount of what you described will be necessary.

I've been thinking about using a bridle arrangement with 2 chains, and adjusting the links to tip the engine forward and backward. The load leveler is much smoother, so I'll have to dig through a few metal scraps and put one together (I'm getting increasingly stubborn about chinese tools...)

Yikes! I was afraid of this! Did the damage you described happen on a stock head or an aluminum one?

Out of paranoia and a preference to build heavy, I made the head puller to use all four plugs:


Hopefully the plate would take the brunt of the dynamic load from shifting, leaving the plugs to simply hold the engine. I'm thinking it will be advantageous to use shorter bolts on the studs, and leave them in place to minimize flexing of the spark plug bolts.
