Overhauling Jack
« on: February 09, 2019, 06:12:33 PM »
I have the original two and a half ton jack that came with my RFSV. Unfortunately it had a tag attached that said do not use faulty.
I have sourced a repair kit from the jacks manufacturer. So as i am going to try and get to Corowa i need an operational jack just in case.
It is currently sitting in a container upside down on my work bench draining oil.
My question is there is the screw that is the filling point for oil and what looks like a female plug in the top of the jack. will that female insert stop me from unscrewing the top off the jack?
I dont have a spanner large enough to fit the top of the jack so my intention is to use the vice to hold the nut and apply a bit of force from a hammer on the bottom to get the top off.
Am i on a reasonable path or should i be doing something else?

While I am asking questions. I had a turbo fitted a few years ago and i now notice I have oil leaks around the inlet manifold near number 1 and 4 pots. there is oil up on the underside of the bonnet. not loosing a lot of oil but its enough to need attention. So replace the inlet manifold gasket???

How did you go overhauling the jack?  Did you manage to get it working again! Any tips as I am looking to do the same.
cheers

no dramas you just need a spanner big enough to undo the top of the jack.
as you disassemble it lay out the bits on a clean rag in order. Make sure you place the seals and bits in the right order and in the right orientation. I mucked up the big white main seal and buggered it up. I had to go to a hydrophilic shop for a new one.
All in all its pretty straight forward. Any problems happy to help out if I can.

one more useful tip. If you dont have a spanner large enough to undo the top of the jack use your bench vice to grip the nut and use a set of stilsons to twist the body of the jack. Works a treat or at least it did for me.

I take it you got the overhaul kit from the jack maker? Saves a heap of mucking around.

Mention of oil coming from the intake manifold gaskets.....I d be sure to remove the hose from the turbo compressor end ,and see if the seal is passing oil......you may not know,but enough oil from a turbo seal will cause a runaway that cannot be stopped by the governor......the only quick way to stop a runaway is to engage high gear and stall the motor.
