Crank front oil slinger

Anonymous · Post by **Anonymous** » Mon Jun 13, 05 8:10 pm

Neither my 318 or the 360 appear to have a crankshaft oil slinger fitted. Was this only fitted to 340 motors originally? I note that Mopar performance stock one for all small blocks

There should be one.

Nope, not on either of my small blocks, furthermore when I tried to order one from Real Steel they said there was no need for one and that was why they didnt stock em. Maybe more crucial on Aussoe motors?

Guy, i'm happy to fit one but no one stocked one, Rodleys, US automotive, Real Steel, had the impresssion that with a new seal they shouldnt be necessary.

See my thread about what they do if fitted wrong !!
HemiPerformance in Australia say they throw away the oil slinger for the straight sixes, there is enough chain lube from the oil dripping down onto it from above. If the oil seal is fitted properly then you will probably be OK, but opinion is divided.
It was fitted when new, there must be a reason, no manufacturer spends money on bits that it doesnt need.
I would suggest worst case if you leave it out will be a leak from the front seal, just call it rust proofing for the K frame.

I don't think it is there to hold back oil from the seal is it?

I thought it was to spin oil up from the small pool at the bottom of the timing case and throw it up to keep the chain well oiled. I would use one. The last thing you need on a performance engine is wear or stretch in the timing chain.

Apparently they were fitted by the factory to bigblocks as well, although I've never found one on any motor I've ever stripped. I think they are a good idea though, so I got a couple from Mancini, one for me "cooking" motor and another for the "better" one. There is a chain tensioner available now for small blocks, now that's an even better idea!

Blue, if I could get one tomorrow i would, but i need to finish this motor. I note that there are only 3 retaining bolt holes (see my related threads on 'does it need 3 or 4 bolts on the cam plate?')
The timimg chain has no apparrent wear (its a comp cams double chain ( despite the previous builder using no slinger and having the drip rail in completely the wrong place!

My 440 had one Blue.

Most of the big blocks I have done have had them and I think Matt is right, it is not for chain lube as such but more to stop excess oil hitting the crank seal.

Noted.

Is the big block one the same as a small block one? Do I need one with a gear drive? I have a big block one that could be replaced at a later date if it helps, Miles.
