Wacker RD11A no vibrator.

[antpoo]

Hi all

I just loaned my roller to one of my mums friends in perfect order and collected today 8 days later and it does not vibrate. He told me it never worked which although possible, considering I used when I dropped it off to him it seems highly unlikely.

I’ve tested the two leadsgoing to the button and I have power, although it seems to light circuit tester constantly if button pressed or depressed. Does anyone have ideas? I was reading a thread about an exciter, not sure what that is, but will no doubt find out soon enough.

Thanks

Regards
Andy

Update, switch appears in perfect order right up to the solenoid. I’m guessing perhaps solenoid is faulty.

Update, solenoid functional, tested with screwdriver. Hydraulic oilflows to manifold from pump, and I took one hydraulic hose of exciter motor and oil flowing strong when I turn key. Possibly exciter motor damaged?

I will have to pull off tomorrow and check.

Last time I lent this machine it cost me$300 for new throttle cable ,, now this. Lesson learnt, Do Not Lend!!

I know this is a pretty old thread, but did you get to a resolution? I’ve got an RD12 that’s not vibrating like it should and the manual leaves something to be desired.

Hello

Yes I did. The solution was the little yellow ‘coupler sleeve’. If was not expensive and it was very simple repair. It is a crucial component for the vibration. I’ll attach photos. Part number on label.

Thanks! I just found my problem today. Someone had installed the wrong kind of hose on the suction side of the exciter / steering pump. The hose had collapsed in on itself and blocked flow. Problem solved

Glad to hear. I’m certain your coupler sleeve will go one day however lol, They are absolutely designed to fail.
