EBR Hydro Disassembly

Calvin Laszakovits /

Having issues removing the bottom m6 hex bolt on ebr hydros. Anyone know what the proper way to lock the inner cartridge to get the bottom bolt out? Thanks

Re: EBR Hydro Disassembly

Mount the forks in the triple tree , then remove the bolt .

Mounting the forks in the triple tree does no solve the issue. The bottom bolt spins freely, not coming out.

In that case , you have to find something to slip into the upper tube and hold the inner cylinder from turning .

Some have notches to accept a locking 'tool' , which most times can be easily fabricated .

Shine a light in the upper tube to see if that's what you have .

Sometimes having the fork completely assembled will be enough pressure to hold the cylinder while removing the bolt .

Exactly, so what I’m asking is if anyone knows what the correct sized tool is. I’ve looked down and can’t see an obvious answer. I tried with it completely assembled to leave tension and it wasn’t enough.

Not the best tool , but , I have used a wooden broom handle and had success .

in the plumbing section at HD theres this tool that grabs the inside of a pipe to rotate CCW turn out.

That tool is called an 'internal pipe wrench' .

Usually comes in a set : 3/8" up to an inch .

Awesome, I’ll see if I can grab one of those. Thanks.

Why are you taking them apart? These forks are not even technically hydraulic. They’re more like spring shocks with oil resistance. There is no seal for the dampening rod or really any sort of internal valving whatsoever.

Maybe he's trying to find that^ out for himself ? ;)

I would . Just so I know for fact what's in there .

A tear down to the threads is the only real way to know your bike .

The seals blew and I wanted to replace.

For anyone else trying to do the same... the internal “cartridge” is not keyed and can only be held by an internal pipe wrench that measures < roughly 7mm. These are “long version” EBR hydros sold by treats for derbi.
