Oh dear, while cleaning the parts ready to assemble when I have the bell housing and gearbox mounts made, I found that the intermediate gear has a casting imperfection:
It would seem that during service the imperfection has come out and allowed a portion above one of the roller bearings to become proud. The thrust washers have done a good job of polishing the outer face flat, but I'm cautious of the fact that this blister may proceed further.
So, as this is a 14D suffix A 1.003 LT230R box, as it seems to have couped with life so far, should I just fit it and forget it. Or as there is the potential it can still blister further and take the thrust washer out (which can no longer be sourced, I purchased the last two in the country!), should I source a new old stock item
