Need help finding a rod bearing for the youngsters Hot rod
Hello, I am working on the kids hotrod at the moment. We also pull garden tractors when dad(me) isn't working on the truck.
I need a rod bearing designed for a 1.575-1.600 crank pin. Width isn't critical, but needs to be under .750 so less machining is required. It needs a wall thickness around .0585-.060. My big end of the rod I am using can go out to a 1.6940. The current rod is just aluminum with no bearing material. I have had a set machined for .0035 oil clearance but when you buzz the engine up to 6000 they don't last that long before the rod glues itself to the crank. Basically I am machining a non insert bearing rod for a bearing insert for the reliability and I'm trying to get a season out of the engine without catastrophic failure. Oh, The engine is a Briggs and Stratton 180 degree opposed twin flathead. The kids need to get interested early in life and as of now my 7 year old daughter is a real gear head. If anyone can help I'd sure appreciate it. My local performance machine shop says there to busy for this kind of thing. Thanks Dennis |

Maybe this will work for you.
This is odd but very first bearing I looked at would be almost perfect I think. Its for a Toyota 1295cc, 1425cc, or 1587cc I see them listed under GM engine too so this is probably out of that little Toyota-Nova car also know as the "Toylet". Federal Mogul part # 1025RA std shaft diameter 1.574-1.5748 parent bore diameter 1.6931-1.6939 wall thickness .0587 bearing width .673 |

Thanks for the reply Greg. I will give that a shot. If you find a bearing close to what I need with a thinner wall thickness could you please post the part number. The thinner I can get one, although they probably don't come any thinner than .050, the better.
Has any one ever done this before. I know its been done to kohler single cylinders and I've heard of it being done to some model t or a engines. Dennis |
