Front oneway maintenance

[Elliott Hopkins]

Particularly the NTC3 roller for the BJ4WE.

What do I do then? Clean up as normal with Propan-2-ol/motor cleaner/washing up liquid then ...

Do I oil the one way bearings? Or leave them as they are without lube?

I've never had to do anything to the one-ways in my cars, when I do a rebuild I will run a dry cotton bud through the bearings to clear any dirt out then put it back in the car, no other work needed

I very occasionally blow mine out with motor cleaner and then re-oil with 3in1.

Current one way is 4 years old on original bearings

I am guessing that your oneways are standard bearings. How do you clean the poxy one ways that have a shed load of circular poles in the bevel, as if I do clean them they will fall out and the one way will stop working.

Regular oil on one-way bearings is a no-no. The roller needles need to be able to grip the shaft for the one-way action.
option 1 is Serpent one-way lube (oily stuff, but silicone-based)
option 2 is the transparant diff grease. Diff balls also need to 'grip' the plates...

Diff grease, interesting. I didnt think of that, I used vaseline (I think it was) but associated clear grease will do the job. Thanks for that.

I can second that!

1) remove "original" oil with brake cleaner (also when cleaning)
2) use Serpent one-way lube

WD40 also works fine, but that stuff from Serpent simply is the best.

Be careful if you use compressed air, it can blow out those pins...

Thankyou for your replies.

Xray also make a one way lube.

Not actually true. Unlike a ball diff, there's a shallow ramp angle which creates very high clamping loads, ensuring they don't slip.

I was investigating big one-way (sprag) clutches a while ago, and the bloke said that the only problems are caused by oils with extreme-pressure additives - basically hypoid / LSD / rear axle oils.

3-in-1 has always worked a treat on my one-ways.

since I'm a cheap bastard , I use ball diff grease.
Elvo is right : regular lubricant is a no-no ! I makes the oneway spin better, but can cause the pins to slip destroying your one way very rapidly.
