Re: Balancing an engine at home (Newbie)
I sent Murray a message and he got back to me already! Sounds like he is 4 weeks out. Does this help quite a bit with the vibration? I don't mean to ask so many questions, I just don't understand it yet. Do I need to do anything else to make it work? Thank you.

Re: Balancing an engine at home (Newbie)
I smoothed the casting ridge on the side of the rod. It wast a scientific job,weight variance an the piston has a greater effect on vibration than a weight variance at the big end of the rod,its further from the axis (center of crankshaft)
I figured anything would help,the imbalance on a low rpm engine isnt that big of an issue,as rpm rises (like 4 or 5k) it becomes huge. If memory serves I pulled out a 10g variance. |

Re: Balancing an engine at home (Newbie)
Who makes a harmonic balancer pulley for a Model A? Sounds like a good solution to me.

Re: Balancing an engine at home (Newbie)
Chances are that that the flywheel housing will be radial cracked around the bolt holes, almost every one is..
I don't recall whether or not that I read that you replaced that 4 inch tube that drains oil from they rear main. The engine can leak quite a bit of oil if it's missing (Don't ask me how I know) Also, there is a tiny tack weld that prevents it from turning itself out. If you have access to a large lathe, turn some weight off that monster flywheel (63 lbs) There are drawings of where the extra stock should be removed. Then have the flywheel professionally balanced. (cost, about $60-80) This will reduce the rotating mass. Check your compression! Ideally each cylinder should be within a few lbs of the others. Terry |
