VDF Heidenreich und Harbeck M530 - clutch -oil pump problem

Hey,

my Name is Glenn from Germany. In 2005 I had the chance to buy a VDF Heidenreich M530 from a local factory producing shafts for tractors etc. I got a lot of accessories including the original documentation. The optical condition is not good but the bed is in very well condition.







After some time I had trouble with the forward clutch. It needed readjustment. Opening the spindle housing and looking for the clutch. I observed this in the backward clutch.



It seems that this is a damage by using the clutch for breaking. Last year disassembled the hole thing, bought new clutch lamella for the forward chuck, the old fine ones went to the backward clutch. Some months age I installed new needle bearings, new gunmatal washer (did by my own), new shaft bearing and put assembled everything together.

























At the first test run with new lamella and bearing I observed the following ringing noise

I think there is no mechanical problem with bearings. It is a problem of missing oil in the main shaft, that causes first problems with Lamellas and if I really would run it also with the needle bearings. I thought on 2 possible problems, first optioans I rotated the pump shaft by 180° which means the oil in the clutch is blocked. I don't believe that. Second, My oil pump is not original, somebody build a new one and assembled it. Does he forget the lubrication for the main shaft? I see no way for the oil to go into the shaft. Has anybody information how the oil goes into the main shaft to go out at the clutch? Maybe a picture of an original VDF oil pump?

Testing what happens if I pump oil inside....runs out of the preasure bearing and maybe the clutch.











Best regards,

Glenn

At this moment I don't own this model, but if I remember correctly the oil is added throught the flange on the back, where the motor is mounted. This flange has to be in the correct position otherwise the oil is blocked.

The same procedure as every year. James...

experiment with electric pump:



Wow...oil



I found the following information in my documentation





but I still don't understand how the oil comes into "Hohlwelle" from the pump...

You can contact the firm Mammut in Germany, they took over the whole spare-parts stock from Heidenreich&Harbeck/Makino. They should be able to answer your question.
