Location: An island off southern Tasmania. | Here is where the problem is when it gets noisy or seizes.
hardest part is getting the helical gears off...its a left hand thread allen bolt.
for me the bearing race just disintegrated as per attached pics.
enjoy...

series 5 it is indeed....it used a 1/4 of a tank in 40 kilometres...so worked it pretty hard.
Gotta open up the oil weep hole to give it much more oil, seems like a design issue to me....about the third one I have had do it.
Symptoms are noisy and rattling sound. |

Location: An island off southern Tasmania. | Just for anyone's information, the cog gears in the neck are held on with allen bolts.
The "master" driven cog is RH thread, the "slave" cog is LH thread.
saves breaking it by turning it in the wrong direction...LOL
My failed bearing was the slave as pictured.
How does just one bearing fail? stuffed if i know....
anyway changed them both.

Location: An island off southern Tasmania. | Unit fixed...perfectly.
80 bucks worth of bearings, double race bearings by NTN 5205C3 is the part number for both.
Funnily, both swim in the same oil and the other one is fine...see photos?

| Hmm,,, i had better be careful because I have a Sprintex S5-335 bolted onto my BA Falcon 4.0 6yl.
And Just like yours, it can be a bit of a Pie cooker too.
FYI-Too much oil cooks those bearings & not enough seizes them.
Finding the happy medium is the hard thing because Sprintex suggested fluid levels come from a blower sitting on a work bench & the correct oil levels can be a little different in the real world.
Mine isn't a direct feed version & it takes 60mil exactly, & any more oil than that it gets pie cooking hot.
Any less than 60mil & it runs noisy as shit.
But just remember not to run it with too much oil or you will overheat & kill the bearings in No time flat. |

Location: An island off southern Tasmania. | I think I am giving it too much oil...thanks heaps for the heads up.
the sprintex kit has a weep nozzle that blocks up so I opened it up a bit...
Which oil are you using?
might try your way.

I use Redline 75W90ns (hard to believe but the ns stands for "non slippery"

| I forgot to add that the fitted Supercharger orientation makes a difference to the amount of fluid that is needed. I have an fluid level chart for each fitted orientation of the S5 series saved somewhere. I will find it tomorrow & post it, or you can check Sprintex, they used to have one on their site.

Location: An island off southern Tasmania. | With all due respect to Bongo ...I have had a rethink on the advice about too much oil.........
It might be the case on the Ford where the oil is locked in...but on our kit the oil is sucked out by the rocker cover vacuum...so it cant really be overfilled because it just flows from the bottom of the nose assembly.
If I make it way too big i would lose overall oil pressure so have been careful about it.
I did actually speak to Mark at sprintex, he approved the idea as long as it wasn't TOOOOO big a difference. |

Yes that is probably the best way of doing things for your setup. Yours is factory,, whereas I built mine myself from scratch & bolted the S5 onto the old girl.
I was thinking of kitting mine out with the vacuum oil feed, it seems that it would be a more efficient way of doing it.
By the way, did Mark Ambrosius (from Sprintex) have any ideas as to why the bearing may have failed in the 380? |

Location: An island off southern Tasmania. | Ours uses the engine oil which is rated at 10w/40...with recommended intervals of 10k/klm.
Yeah lack of oil is what killed my bearings.
I have now had 6 failures between three cars.
Admittedly 3 of them were low boost issues with series 3 blowers that were replaced free of charge with series 5 units.
The reason I enlarged the oil feed was to abate the bearing failures...I think I am on top of it now.
