Can you identify the part in this breakdown? I don't see any item listed as you have called it.??http://www.mtmc.co.uk/Qualcast-CLASSIC-PETROL-35S-/-F016305203-Spare-Parts__p-43012.aspx
I am referring to the spring that connects the cutting cylinder cable to somewhere in the region of the jockey arm assembly cylinder. Hope this helps.
Hi, I have looked at the link you sent me. My Qualcast is Serial No: 017356A. The part I am referring to is the top spring (No 70). Hope this helps . . .
Thanks for that -- I will try that out at the weekend. Here's hoping . . .
Hi koboma, The spring I am referring to is No 70/32, not 70/30. Sorry if I misled you. Can you still help?
Followed your advice but without success. The cutting blades still do not engage. The cable does not engage the cutting cylinder.
Is the diagram correct for Qualcast Serial No: 017356A . . . .
My jockey arm cylinder has two holes in the back plate, one for the arm's return spring -- is the other meant to house the cutting cylinder cable return spring?
Hope you can still help . . .
Thanks for that. I haven't a clue what a stripped gear would look like, but when I turn the blades it turns the clogs and belt -- and vice versa. That indicates to me that all is well in that area.
As you can tell from my earlier messages, I am a layman when it comes to mechanics, but logic tells me that the return spring of the cutting cylinder must actually engage with a working part. Or am I missing the plot?
Followed your advice and everything appears OK, but the moment I try to operate with the engine running nothing happens - the cutting blade does not turn. Any more suggestions? I have put the machine away until I can return to it next weekend. Thanks for your input today.
Still no success . . .I have checked (without engine running) that the cables appear to be working and engaging correctly. I did notice, though, that the jockey arm cylinder is not moving. Does this point to the possible problem? Hope you can help . . .
Yes, I can move the cutting cylinder manually and all cogs respond. The two lower pulleys respond, but not the top pulley. This turns with extra force applied, but does not turn in unison with other cogs/pulleys. Land drive cable operates. When I turn engine on, the cutting blades simply don't engage. Any clues?
