Trying to bleed system after first hydraulic filter change

sirmombo · Feb 23, 2014

I changed my hydraulic filter for the first time yesterday on my 1430 and tried to follow the bleeding instructions. There are two charge pressure points on the pump. One has a hose and the other is plugged. The hose segment I received for bleeding has a fitting that matches the hose so I disconnected the hose and attached the bleeder hose. I disabled the engine and cranked it over. The first time I got a steady stream out of the bleeder hose. The second time, a little less, and now I get nearly nothing. I have cranked it many times and seldom get more than a few drops.

I verified that filter is completely full of oil. Does the pump have to be reprimed?

Thanks for any info,
Bill

It is a plug, not a hose that you want to attach your bleeder hose!!!

Thanks for the quick reply. I put the bleeder hose where the plug was and reconnected the other hose and it's now working. I did have to disconnect the top hose to get a wrench on the plug. I don't know if a real stubby 9/16 wrench would work or not.

Glad everything worked out for you. I manage with an open end wrench on mine - can just manage to get it through the hoses enough to do small arcs. A crows foot wrench might work as well. A gearwrench combination ratcheting flexhead wrench works well on the plug and that is the one that really matters. Getting the bleeder hose fairly tight is not so important.

Ha! Coming up on my 1st hyd. filter change, I also was unclear after reading manual if air bleeding had to be done from one or both ports... Took me awhile to find this thread, but I'm glad I persevered.

The 'cranking the disabled diesel engine' instructions are also unclear to me... But, from another thread, I seem to understand that I need to disconnect the electrical connection for the Fuel Shut-Off Solenoid (behind the alternator belt)?

Yet another thread provided me with good instructions for running the bleeder hose into the hydraulic tank... (That should be in the manual!!)

Thank-you in advance,

Yes, you want to disconnect the electrical connector near the alternator

I personally would not run the hose into the hydraulic tank. That is just an opportunity for more dirt etc to get into your oil. I put a little oil into a small glass jar which I then set in a coffee can. Then I stick the end of the hose into that. Easier to see and you are not exposing the oil in the tank to dirt.

I tried Kens suggestion and somehow ended up soaked in oil when it shot out of the hose. YMMV, and yes, I am a bit of a moron.

Carl, I think my directions to you were: Look into the end of the hose and when bubbles stop coming out, you are good.

I have never had that problem. Did you have the engine disabled?

Well, the output end of the hose, is supposed to be in the tank, not pointing at you.

Like the idea/advice Ken! I've been through all your pages in the past; somehow forgot you had one about the hyd. filter change... Great info as always; so appreciate what you have taken the time to post in the past; it continues to be of use today!!
