I’m know I’m going over old ground again, but just in order to confirm, I'd appreciate some input from those more expereienced. I’ve had my ZF inverted, but I’m checking the work that’s "been done". The place that did it was a bit casual about the whole thing and I want to be sure that it’s been done correctly. Having said that, there seems to be few critical items and I don’t want to pull it apart unnecessarily.
Apart from the work associated with the physical inverting of the box and reversing the crown wheel, the items that seem to get mentioned are:
1 Various fill holes and drain plugs. I think we’re OK there.
2 A breather gets mentioned occasionally for hard use. Not required for street use or is this recommended anyway? What’s the view?
3 A trough under the gears feeding oil to the crown wheel. This is supposedly in place in the standard GT40 configuration (inspection plate on top) so no action required?
4 Drill a few holes into the bottom of the wall between the gearbox and crown wheel housings. I assume this is for drainage to change the oil (?), but this isolated oil could be removed by a suction tube, or are they required to distribute the oil after filling? I would have thought not. If they’re not required and they’re not in place, I won’t be pulling it apart to install them.
5 Output shaft bearings have to have oil input holes(?) on top and the bottom ones filled in. This seems like the item that could be a problem if it’s not been done. Does anyone have a photo of what this looks like? Are these the square openings in the bearing housing shown in the manual? What are the existing holes filled with? I would have thought welding would have distorted everything. What is recommended?
Is there anything I’m overlooking? I don’t want to break this transaxle. The trouble I have is that, in Perth, there is no-one that knows anything about ZF transaxles.
Any help or photos greatly appreciated.
Cheers,
Lance
