Sub BT oil change

[Blakey111]

Hi Dave,

Thanks for the response, If I'm honest I think that motor may have a small amount of the previous grade oil in it, we did have 230v Sub R then switched to 24v BT after mechanical fault and I can't remember If I topped them up 2 years ago of the wrong oil unintentionally of course, its why I want to change the oil in that motor to see if it makes a difference.  Do you know if its just a case of undoing the oil cap and using a siphon kit?  I got some of the winter 24v oil now to replace and try.

No problem! There's no other plug that can be removed to drain the existing oil in the motor, but if you open the bleed valve right up and funnel the new oil in, this should do the trick. Might just take some persistence as the old oil will be thicker.
