Walker hydro going bad?

The left side hydro on my walker has got on really bad, almost won't catch at all, have to pull lever all the back to get any movement, sounds real bad like grinding at times. Opend up the Allen key check oil level spot, have some metal shavings on the magnetic screw. Obviously hydro pump is on last leg on that side.

Went to dealer today, they wanted $800 just for part. Curious if anyone knows where online I can buy a hydro for cheaper? Looked but couldn't find anything.

It sounds like to me you checked the oil in the gearaxle. The gearaxle and hydro are two different parts and are bolted together-look at you parts manual and if you dont't have one, go to the Walker website,they have the manuals for you to look at. Make sure you know which one has the problem. You can find some of these parts on ebay and also Emmett Equipment out of Ohio, they will mail to you. They have a used gear axle for $200 on there site.

It's not the gearbox, metal shavings is normal wear and tear. The pump itself has failed and will need to be replaced.

As long as there aren't large metal chunks just shavings. The hydro pump has let go, in over twelve years of running walkers we have never replaced a gearbox.

Surplus Center has a few sizes available. You'll have to check carefully to see if all the port sizes will work right for your mower, but the price is right.

Drain oil out of hydro from bottom 11/16 th bolt instead of using 15 w 50 use mobil straight sae 50 weight oil. when you put new oil fill it from top 11/16th bolt , not from plastic cap it has a super fine screen and it'll take days and you may not fill it right, then fill to cold level in plastic filler cap. release hydro and roll wheel b4 u put top bolt in to release air out of hydro the tighten bolt it may get you a couple yrs . if not inbox me ill get you a number to a dealer for 700 shipped to your home

usually they last around 3000 hrs then youll notice they run well 1st thing in morning and a couple lawns later pump is bypassing when hydro is hot and you cant go up hills bcuz one pump is not enough.
