What are the mighty BCF sage`s thoughts on this one?

Can you put new clutch plates straight in or is it a case of they must be soaked in oil before they are put in ?

I seek your advice Thumbs Up

It is common practice to soak them in oil overnight.I have always done this,but with workshop times being limited there must be times when this is not done.

Never done it, not had a problem. I think it is an old wives tale TBH.

Well I put them in, but dipped them in oil before I put them in place.
+ new metal plates and new springs and all appears to be good Thumbs Up

Clutch slip is gone Smile and it appears to be a bit smoother to engage gears Thumbs Up

So far so good!

I see it this way - if the clutch is supposed to be a wet clutch,you install new plates into the basket and replace the side cover.You then fill the engine with oil to the correct level.Some parts of the new friction material will be affected by the oil.This could compromise performance - it might not.But if the friction plates were soaked beforehand,then plate action would be uniform.

But then I have only been working on bike engines for 36 years.

All plates were dipped and left in oil for approx 15 mins before I put them in, whilst I was doing other stuff.
Nothing was put in the bike dry (ie metal plates were smeared with oil also) and the bike was gently run with the clutch being engaged and disengaged several times before any load was put on it.
All appears to feel fine and smooth at the moment.

I have pulled the side off many an off-road bike and slammed in a new set of plates and then ridden again that same meet without any problems.
I was seeking wisdom in that it may be different for road bikes?
I would of rather given them a soaking in oil for a few hours but time is of the essence.

In the past I have never soaked clutch plates for my road bikes ie x5 GT 250`s & RD 250 but was wondering if there was a reason for doing it now, for example the friction material is different?

So what are your clutch plates made of then?

Last EBC clutch kit I bought had instructions on the box to soak the friction plates in oil before fitting.

A clutch is a centrifuge and centrifuges are used to dry stuff, so anything more than the barest minimum of oil is going to get thrown off the surface of the friction pads during the first few seconds anyway. Any oil not on the surface of the friction material isn't actually doing anything.

Except that oil is normally introduced at the centre of a clutch and is used to help keep the plates cool as well as to move away the debris.

It really is one of those things that probably isn't that important to do, but it costs nothing to stick them in a tub with some oil overnight whether it's wasting time or not.

I usually stick them in a bowl of oil when i start the job, they maybe get an hour to soak before going in.
Got to be better than having them fitted dry

Turn the sound down for obvious reasons...but note the plates soaking. Thumbs Up

On some bikes, not all. That has no bearing on the actual topic of soaking plates anyway.

So in conclusion it might of been better to give them an overnight soak, but as time was limited, putting them in after a 15 minute soak wont be to much of an issue Smile Thumbs Up

gave everything a look-see and try out today and all seemed hunky-dory Thumbs Up
