Here we go again. PLEASE look very closely at this picture! There's a reason the slinger is in perfect alignment with the fuel pump eccentric. It keeps oil on there to keep the fuel pump arm from grinding away. There are a lot of members on here that say they're not needed, the picture proves otherwise. The fuel pump arm has constant spring pressure pressing on the eccentric, that's steel to steel contact under pressure, there needs to be plenty of oil there to survive. Chrysler knew this and put the slinger on there. RUN THE SLINGER !!!

Wait, why is yours facing the wrong way??
Just kidding. No I agree with you. Plus the eccentric is hardened. Once those things start
getting any deformations on the surface they can
tear a pump arm up in no time. The only thing I
question is in the service manual they talk about
keeping oil off the seal..... kinda thing thats secondary.
The main purpose of the slinger is to keep excess oil off the cover seal to help prevent a leak. As for oiling the fuel pump accentric that thin piece of tin will slice through the oil before it will throw it, it is to smooth a metal to throw anything. There is more oil splashing off the timing chain and sprockets than is needed to put a nice coating of oil on everything there. As for needing them there are problably as many OEM engines out there without them as with them and not a nickels worth of wear difference. To each their own.

It's not facing the wrong way, if it's turned around the curvature will hit the chain. This is the way it goes. This is a 1969 340 engine. If you would mock up a crank, timing gear, slinger, timing cover and balancer you'd notice there's an inch gap between the slinger and the seal. Hardly close enough to keep oil off the seal, no, the slinger's job is to sling oil onto the eccentric and timing chain & gears.

If thats true then why did mopar ALSO put the slinger on big blocks....whose fuel pump eccentrics are part of the cam and certainly NOT oiled by the slinger??? Hmmmm??????

To oil the timing chain & gears. Big blocks didn't have a dripper like the small blocks, there's no cam plate behind the cam on a BB.

Actually the function of the slinger is to BOTH keep excessive oil away from the front seal (it was a method of minimizing warranty issues--oil leaks) AND to sling the excess oil onto the chain where it certainly would do no harm, but most likely not necessary. We've certainly seen engines run fine without them, although I would agree that a small block has the aditional reason to run one due to the fuel pump eccentric's location. A big block is less dependant on them.
BTW...sprockets, not gears.

Before the advent of aluminum gears with nylon teeth Mopars were built with steel gears and steel timing chains requiring lots of oil. As for that flat piece of metal not being able to get any oil on it to throw, just quickly dip a razor blade in oil and see how much oil it collects, plus if it throws no oil, it won't throw oil away from the seal as you state. Kind of disproving your own theory.

Our engines are some of the best designs ever and I don`t waste my time thinking I know better than the Chrysler engineers who spent years perfecting them. i won`t assemble an engine without the slinger.

Oh boy, I didn't mean to start this kind of slinging
(pun intended) I was just looking for some feedback. As for chrysler engineers, well my father had 32 years there and my brother has 20 in now. Yes they do a good job but I could tell stories........

Why not just as many came down the line without them as they did with them. They were hit and miss from teh factory too.
