My GTD40 was fitted with an upgraded UN5 transaxle some years ago, replacing a UN1. Before I owned it. Was investigating a clutch problem recently, and discovered that the input shaft has almost 3mm of vertical movement (none in other directions). No symptoms in driving, but looks like a problem with alignment. Surprised it hasn't disintegrated.
It's attached to a fairly mild 302 Windsor.
Has anybody fitted a UN5? Any problem with alignment? It looks like the UN1 adapter is still there, but the UN5 bell housing may have been modified for some reason.
What do the experts think?
Haven't looked inside the box yet, but assume it's not pretty and likely to be damage to the input shaft bearing housing. Possibly need a new box. Should I consider going back to the UN1? I think I can get another UN5 here, but concerned there may be a fitment problem I don't know about.
Any advice gratefully received!
