Broke the front hydro cylinder

[SMC17 0]

Thanks to everyone on this site I was able to install my new Honda in my AC620 and it is running very well. Due to the blizzard I swapped out my loader for my front blade. This was my first time using the blade and after referring to the manual I installed it and thought I was ready for the snow. Of course after I fired it up in the morning and made my first pass I noticed a nice streak of Hydro fluid running right down the middle. Disconnected the front cylinder which was oozing fluid and added a quart of fluid to the tractor and proceeded to push all the snow off my driveway with the blade in float. Man this 620 can move some snow! Compared to my Case 222 it took half the time even with the blade always down and no chains. It was a chore to push on my driveway/ice rink without chains and I'll definitely get them on for the rest of the winter. Anyhow, I now have a cylinder that needs service. I'm hoping it's the seals. Is this something my local hydro service shop can rebuild for me? Or do I need to get replacement parts through Simplicity? Sean

I would think that it would depend on the cylinder. Some are welded together and can not be repacked easily. Others can be fixed easily. Either way, I would think any place that does hydraulic service should be able to handle what ever type cylinder you have. Elon

I had a simular incident when I installed my first blade. I had the inlet ports facing the wrong way(up) and when I raised the blade up I broke one of the fittings off. Check that first. If this is the case, you'll need a #5JIC X 1/8" NPT 45degree fitting to fix it. Unless you bent the cyl. rod I can't think of anything else that would have damaged the cyl. Tkae another look at it and let us know.

Dave, I know that I installed it facing up. I didnnt' inspect it that closely but it sure looked like it was leaking out of the bottom of the cylinder. I looked at the manual this morning and noticed that the fittings should be on the bottom of the cylinder install and not on top. Thanks for confirming. I'll check it when I get home.

Sean, Both of the fittings need to be on the underside of the cylinder so it wont hit when the blade is raised. So if they were on top I would suspect the fittings got damaged.... How is that 24 Horse power doing for you? Aaron

Dittos what Dave And Sean said. Same thing happened to me the first time installing the dozer blade.

Just as everyone suspected I'm joining the elite club of those who installed the cylinder wrong and cracked the elbow fittings (both of them) at the threads! I was able to extract them carefully and it should be an easy fix if I can track down the parts. Thanks Dave for the part description it'll come in handy. Sean

Not sure just how you could do it as I haven't needed to try but you might want to flush that cyl out real good to make sure you haave ne metal filings in the hydro system

Another question. What kind of fittings screw into the cylinder itself? The manual seems to show straight fittings not angled at 45 degrees like mine. Napa doesn't have a match. Just to clear things up I broke the fittings that screw into the cylinder and not the hook shaped fitting that connects directly to the hose and then screws into the fitting I broke. Can I use straight fittings? Thanks, Sean

I would try 45 or 90 degree fittings, so the hoses will at least be closer to the direction they will want to be in once hooked up, Try a dealer they may have the parts, or something simmilar from a latter model

Well I went to my local Hydro shop and the #5 fittings are odd ball. He didn't stock #5 fittings in either 45 or 90 degree. Also my hoses were chewed up so he's ordering me some new hoses and hose connectors. Figured I better get this done correctly before the next big storm or pile of dirt hits my house. Thanks for the input guys. Sean

That same cyl was used by JD on the I believe 300 and 400 series tractors. Bought a new one through the dealer in Fairbanks for my 4040. It's ok from JD, it's painted black:)
