Hi guys while making some coilovers today for my car I cut abit too deep with the grinder and one of the shocks leaked everywhere itS welded up not but I'm wondering what oil is needed and if it was special or would any oil do? Thanks in advance guys

Motorbike fork oil would be good, but it comes in various grades.

Where did you cut through? if it's in the stroke of the seal, there's no point refilling it as the seal will be ruined by the burr in a few miles anyway.

I was cutting the hub mount off the bottom to convert them into sleeve type and cutting into the welds at the bottom of the shock I went at slightly the wrong angle and it started to weep out
And cheers but what grade would be best? I want them as stiff as possable as its for a track car I will be useing 500lb springs so with the grade dose the bigger number mean thicker which means stiffer shocks?
Thanks again guys :-)

We used to use Dexron 2 to stiffen up our cars back in the day and I'm pretty sure LEDA used to use the same thing in their inserts too.

Yeah, higher number means stiffer in terms of the grades. If it's for a track car it'd be worth using a proper damping oil like the motorbike stuff, as it'll be more stable than other oils. We couldn't really say what grade you need as it'll depend on the valving in the damper. Unfortunately unless you can find advice from someone who's replaced the oil in the same dampers, running similar spring rates then the easiest/best option will probably be to try some and see what happens.

due to the bits of metal you'll have floating around inside the damper (from the grinding and welding) the unit will fail in a very short space of time
Throw it away, and put it down to experience I'm afraid

don't do this to me chairchild lol would it be alright if I strip it down and clean it up befor I refill? Then surely none of the metal bits will affect the internals??

You're going to have to strip it and clean it, even a tiny piece of steel from the grinding or welding will jam the valving or score the piston/bore. If you've cycled it since grinding through it, chances are the curse word is already in the valving/scored the walls.

use this chance to properly rip it to bits, and actually see for yourself how the damper works

Could you not leave a piece of magnet permanently stuck to the bottom of the damper to catch the curse word?

I could drill and tap it re fill it then use a shallow magnetic sump plug, I'd still flush them out after I drill and tap the hole il look and see how much new units are first and il do the conversion carefully this time lol if there too expensive il give it a go :-)

unless it was an amazingly powerful magnet - the action of the damper would still see bits of metal/etc floating around, knackering the seals I'm afraid
