Greenmech quadchip 150 issues

[mark_goldfinch]

Hello to all, has any one else had issues with the hydraulic tank splitting on there chipper? Ours was an ex demo machine and now has just over 400 hours use. We have had it for about 12 months and in that time have had four new hydraulic tanks fitted. How hot should the hydraulic oil being getting as it is only a plastic tank and keeps rupturing at the mounting points. Starting to cost abit in down time now as it takes a few days to get the replacements.

Have you spoken to Greenmech about it?

[mark_goldfinch]

Yeah as the replacement tanks have been replaced under warranty and they are investigating the issue.

No problems with mine, had it over a year now. Hopefully yours is an isolated case and they will get it sorted soon, sounds frustrating.

Do you notice if your tank gets really hot? Ours is great for gloved hand warming thats about it.

[Peter]

Not really no. I use the exhaust for that.

How hot should the hydraulic oil being getting

 

No more than blood heat, by the time it reaches 45-50C it is affected by oxidation which shortens its life. Straight hydraulic oil has few additives to combat deterioration.

Had mine just over a year and no problems here.

Mine split in the same place as yours with about 80 hours on the clock. The hydraulic oil/tank was getting hot as you are experiencing. Greenmech fitted a new tank and also installed a small radiator for the hydraulic oil just in front of the engine radiator. No problems since.
