351W front crank oil slinger
Do I need an oil slinger in front of the crank sprocket on my 408W stroker to keep the front seal from leaking? If so, where can I get one?

What is an oil slinger?
My 408W leaked like a sieve out the front crank seal, but that was because it wasn't perfectly centered and the crank just chewed a hole in the seal. Re-assembling next weekend. |
Contact an engine rebuilding shop, or Ford Dealer.

Dave;
I'm on the road now so I don't have access to my info, but I have a parts breakdown (from the Gessford Machine web site, I think) of the Ford small blocks, and it seems to me that the oil slinger was only used in 1969. Check with Ford to be sure. Bill Stradtner |
The oil slinger provided added lube to the fuel pump excentric ( love my spelling ) and timing chain. If you have an electric fuel pump, it is added weight and does little else. Block off the fuel pump openning and leave the excentric and slinger out.
I ommited it on my Boss engine. Just my $0.02 :3DSMILE: |
I have a DAE or 1970's vintage block, and will be using a mechanical pump and eccentric. I just bought a book to help me through the assembly process and it mentions that the oil slinger keeps oil off of the front seal to prevent leaks. The shop I bought the short block from is non committal on this theory and points out that Ford discontinued the use of the slinger after 1979. If there is even a small chance that it might help I am willing to use one, but I can't find one anywhere. If the slinger is sandwiched between the damper and the bottom sprocket, and the slinger is not used, what holds the sprocket in place?

I have a D9AE block. No slinger. The crank sprocket is held on by the damper. Actually, the sprocket can't move anyway, as the timing chain holds it very well.
I never had any dimensional, or stackup problem when I built mine. Ed |
The slinger is made from stamped sheet metal about .060 thick, and is sandwiched between the crank gear and the vibration dampner and clamped togegether by the large bolt holding on the damper. The .060 dimension will not normally present a fitament problem with the belts as you are moving the damper in or out this small amount. Be sure to check for interference with the front cover.
