Hydraulic ram rebuilds?

[_tc]

Hi guys and girls, does anyone repair their own rams? I have just bought a fence post rammer and the ram is weeping so need to fix it sooner rather than later.

Any advice welcome.

Yes, done a fair few now- only advice I would offer is to keep everything spotlessly clean, both your working area and the ram you're repairing. Dirt and grit will only lead to the seals failing much sooner. Also if you're not sure about the assembly sequence, lay it out on the order you take it apart, that way it should help with re assembly.

 

Good luck with it

Yep. Fairly simple to do. Getting the gland nut undone is the hardest part normally. What is the condition of the ram rod and is there any excessive movement where the rod slides in and out?

Great thanks guys, I will finish this job then take the ram off and get some new seals from a local hydraulic place then. Super.

Regards

Not only lay it out the way it comes apart also make sure u note which way round the seals were. some are obvious some less so.

 

As others have said keep it spotlessly clean, if the ram cylinder is painted or dirty check n double check there isn't a grub screw through the cylinder into the gland end, the times I have seen people force a gland end out to knacker the threads cos a grub screw has been present.

 

to remove the nut that holds the piston on the rod i put a piece of round bar in the vice and put the rod's eye over it making sure there is a rag to stop any chrome touching the vice.

 

there really isn't any more to it than that.

A good little trick that I use rather than a chain wrench on ram collars is to use a length of old cambelt around the collar, then grip the ends of it with a mole grips. the grips will then tighten the belt the more torque you apply.

If the rod is damaged send it into a repair shop. If you fit new seals they will be waisted. Get a new rod fitted job sorted.
