Timing Chain Oil Slinger

[geordie]

How do you remove it? My harmonic balancer key seems stuck in the shaft. If I lube it and let it sit overnight, should this just pop out allowing me to pull off the slinger?

slinger???are you talking about the seal?

The slinger should be keyed to the key (ha ha) and just slide off over it. To loosen the key, I tap (wedge) a small screw driver between it and the crank. They are usually tight. If you wanted to buy a new key, you can clamp some vice grips on them and tap it (the vice grip) lightly with a happer. No matter what, it really shouldn't be too difficult.

Thanks Dennis112. Do you think that I will be able to buy a new slinger and timing cover seal at Checkers or similar. I can't find one in the NPD catalogue or Summit. Anybody replaced them and if so where did you get them from.

oil slingers arent too common so go to the junkyard but you can get timing chain cover seals from liek autozone or whatever.

try to avoid damaging the oil slinger as they are hard to find. if you do damage one though all is not lost. ford changed the timing cover in later years and used a shelf over the seal to prevent oil leaks. i know my mercury had one as did the 351w i pulled from a van a number of years ago.

Oil slingers can often be bought through ebay. When you find a slinger, make sure that it is for the type engine you have. One for a 289, 302, 351w should be the same. A 351C, 351m, 400m is a different animal and will cause you grief if you try it on the W blocks.

The slinger really serves 2 main purposes. It may help lube the chain more and it helps direct oil away from the front crank seal.

If you can't find one, you CAN run without it--it is done all the time and I wouldn't sweat it.

Unless you are running a mechanical fuel pump, because the slinger is what pumps the plunger.

 

[geordie]

Eh.............

the slinger pumps the plunger.....er....not on mine. My plumger is driven by a cam on the end of the cam shaft, I think.

Can you provide more explanation please?

Nope. The oil slinger goes on the CRANKshaft. The fuel pump eccentric, which moves the fuel pump plunger, is bilted to the front of the CAMshaft.

Correct. The fuel pump eccentric that drives the fuel pump is on the cam. The OIL slinger is on the crank between the balancer and the lower timing gear.

Better check your manuals. . . . .

Haha, thanks everyone, I wasn't thinking strait.

Do you need an oil slinger?

I know this thread is a bit old, but I found it using search feature of the forum. I just got my 347 stroker long block and am in the process of locating and buying all the little parts needed in order to complete the build. My shop manual also lists the oil slinger, butccording to tis head it sounds like you may or may not need it. I also purchased the timing front cover from the engine builder (CHP) and specified "early version" of this cover. I will be using mechanical fuel pump. If I do need one, where can I get one? If I don't need one, are there any precaution I need to take?

Thanks

I think the 351W part is different, larger than the 302 version. I have a few of them. I pick them up whenever I find them in wrecking yards. Let me know if you want one.

I saw in another thread that if your timing cover has a baffle built in, you do not need the slinger. I have a new timing cover and it has the baffle. Can anyone confirm this is correct information to help me avoid a nasty oil leak
