Hello everyone,
I have two unusual issues with my Schwing concrete pump, About a month ago we got the yearly hydraulic oil and filters changed in the pump as after a job we noticed the the filter pop out had popped on the Main return filter, Since we had the hydraulic oil changed ( it is the correct oil and grade for climate ) the pop out keeps popping and the past week we noticed the hydraulic oil level dropped in the site glass about an inch and could not find any leaks and yesterday after a job while checking everything the oil level had returned to the original level,
These two issues have us a little confused, anybody ever had either of these problems??? and if so would appreciate any tips or info on the problem . |

I have seen the difference between the hot and cold oil half of the sight glass, you should check the oil level ideally at the same time ( best time is in the morning with everything cold); what is the age of the pump? the pop off valve may be bad and needs to be replaced, you can try Schwing for replacment parts, you may have to go the the filter manufacturer direct
besides that, there are two locations, where hydraulic oil can be lost. One is the Stiebel gear box, this would be visible when oil is coming out of the breather. The other spot is your agitator motor lleaking oil into the hopper, this not as obvious.
hope this helps |
