G..G..G..Granville.........!! Fetch your cloth.
Well apart from the person who started this thread (who unfortunately never came back to update us on what the actual problem was on his machine) I know of no other case of a machine with no drive, implements, or fan where the cause was NOT something related to the coupling.

You need Ref #2 on the attachment.
While you have everything apart check the splined connector on the drive pump. Sometimes the bolt #3 can come loose and the connector #5 slides away from the coupler. Unsurprisingly this also results in no drive, implements, or fan.

Same here. But after hearing that, from now on I’ll keep a broken charge pump in the back of my mind next time I come across it. How good are these forums
