Oil leak quick fix on 743

[spudcat]

Using engine oil in hydraulics on 743 and have a tilt cylinder oil leak. Dont have time to fix at the moment. Would a product such as Lucas engine oil stop leak perhaps help to stop this leak? I have read that hydraulic oil stop leak works well on similar applications on forklifts etc. Any advice would be great.

I doubt very seriously that stop leak is going to have any effect on a tilt cylinder leak , it is an 1 hour job and about $25 for a seal kit to fix it , unless you scratched up the chrome or damaged the head gland nut which will cost you more , think of the cost of how much oil you are wasting and if working across concrete what a mess it is making

Agreed, just pull the cylinder off and replace the seals. Unless its worn through at the base and has a leak from where the weld has worn through, i have seen these before.
If its a minor leak, just keep adding till you get time to fix it, I'd never use an additive in the hydraulic system, you don't know what it will do to the hydrostatic pumps. I don't know exactly how the additives work, but i thought some had copper or Teflon that was designed to find cracks and stick inside to stop leaks. If the leak is your rod seal no amount of this stuff will fix that problem as the stick is constantly moving every time you lift or dump the bucket.

Thanks Tazza and Fishfiles for all the great advice. I will change the seals. Happy New Year to all.
