Roof Motor - Fixed Spacer & reusable parts?

[getsetbrett]

Afternoon all,

Front windscreen latch motor working fine & roof retracts as normal to fully down when button pressed.
Main motor behind passenger seat whirring away when trying to put roof up but very slow or no operation unless it is given a helping hand.

My local indy didn't want to remove the roof on my 2006 Z4MR without a plan going forward, he has diagnosed as the motor as the drain holes were indeed substantially blocked.

As we haven't physically seen the motor/pump can anyone tell me the difference between the motors sold with a fixed spacer and one sold without. Is there a difference between pre-facelift & facelift cars......

I am hoping to reuse the other fixings/parts. Is it wise to replace any of the below while I am at it

Pump to Motor seal
*Alloy Spacer
Mounting plate (stainless steel)
Pump to Motor fixing bolts x2 ( stainless steel )
Bowden Cable housing replacement fixing bolts x2 ( stainless steel)
Plastic impeller and fixing shim
Drive engagement pin and spring

Two things from own experience. One, get the pump/ motor moved into the boot, and Two, if the roof is going ok in one direction but not the other it’s more likely the pump head than the motor part that’s at fault.
