400F fork oil capacity question.

[McCabe-Thiele (Ted)]

The manual here says 105 cc for replacement / 125 cc from strip down.
Quite a few sites mention 145-150 cc.
I did wonder if there were variations in volumes due to any change in the design of the fork internals.
Can't rely on the fluid I removed as a measurement as one side was very low.

I'm intending to use 10W fork oil.

I can't remember the quantity that I  put in mine. I used the figure in the Clymer manual and the suspension is great, no issues. I can't check at the moment cause I'm  away from the house.

125cc when refitting and 105cc when refilling - at least that is what it says in the Honda Manual!

Never used 10w fork oil,

I tend to use  ATF,

only personal preference

I read that Honda used ATF in the early days - which of the many ATF grades did you use Dexron 2 ?

Yes,


I used it in the car aswell



If you have an auto box in the car,


Change the oil!!

The box will last much longer

I've run an automatic  car for over 30 odd years now John - I always used to do the double oil change, the second one being a 100 miles or so after the first one to allow for the Torque convertor. Sadly they started to make changing your own transmission oil difficult or impossible initially by the removal of a dipstick, so they can only be done by machine via the drain plugs on newer vehicles. I was a stickler for changing the pan filter as well. Never had an auto box go faulty.

As is the way I gave away the last of my ATF stock a couple of years ago.

I read that in the very early days Honda used fish oil in the forks!

Just the plaice for it I'd imagine.

I'm sorry, I just have no sole 

[McCabe-Thiele (Ted)]

Fish oil would have ensured the parts were  Whale Oiled.

Tuna for higher performance.

😂😂 Cod almighty these puns are terrible.

I think I'll just skate over these silly remarks.

ATF often used as it offered a consistent viscosity of 5 usually, coupled with its inclusion of anti foaming, usually its silicone oil, to avoid cavitation and reduced damping constants.  Quite effective generally.

Quantity, not super critical in these. Enough to keep damper valuing covered through the whole fork travel and not too much that the oil hit the top cap under full compression to give hydraulic locking. Hence the reduced volume on refill to take account of residual quantity left inside when drained.

Heard the fish oil stories before, but don't recall reading definitive confirmation, sounds like it was quite smelly by all accounts. 

I use specific fork/damper oil currently to n help with bush and stanchion friction reduction.

A good variety of pun available to the motorpike and sidecarp rider owner then
