1010 air leak
1010 air leak
My 1010 crawler/loader/backhoe is sucking air. I found the o ring in the tank that goes on the standpipe by the filter was hard and leaking. I made a new one out 1/8" material and it seemed to solve the issue, until I got on a slight slope and then I get the air leak again. I can't tell if it's coming from the tank or elsewhere. I've tightened all the lines I can and the clamps on the suction lines. I'm concerned at this point that I either have a collapsed hose that joins some of the steel lines or I'm missing something obvious, like the o-ring I made out of 1/8" material is wrong.
Any ideas gratefully appreciated.

I might be misunderstanding, but I assume you are meaning on a fuel line? If there is fuel above the line, it can't be an air leak.

Re: 1010 air leak
Sorry, I have a suction leak on my hydraulics. Bad enough that the pump is chattering whenever the loader or hoe is in operation.

Re: 1010 air leak
That can be a tough one to find.

Re: 1010 air leak
If it only happens on a slope, I would check the tank suction line. Over fill the tank to see if it changes anything.
Re: 1010 air leak
Thanks Gus. I'm in the process of changing out the suction pipe hose unions now. The tank should be dry judging by the amount of oil I got all over me, so I'll pull the filter and check the standpipe. Already found a loose suction fitting but tightening made no difference. My fear is it's a crack in weld somewhere, that would be a needle in a haystack thing to find.

Re: 1010 air leak
Might try pressure in the suction line. It would force oil out of the leaky spot if it is in the line. Eliminate one thing at a time.
Re: 1010 air leak
I'm pretty sure the leak is at the pump. Anyone ever tear into one of these?

Re: 1010 air leak
Have you replaced the filter? Not quite the same but a plugged filter caused my vacuum pump to cavitate when transferring wine and caused it to pull in air.
Re: 1010 air leak
Filter has maybe 2 hours run time on it. It's worth a shot though. Thanks!

Re: 1010 air leak
Is there an aftermarket filter for this or am I stuck going back to mother Deere? I found a reference here to a Fram CH6484 filter being a cross referenced option but no one seems to have followed up and verified that. ???

Re: 1010 air leak
Gus, changed the filter. The old one only had a few hours run time on it, but so far it looks like you were right! No air leak so far. Haven't had a chance to work it, but it's better than it was for sure. Thanks!
