So some heavy handed bugger has damaged it during transmission fitting then......

got it in one the tc was not engaged with the pump properly when it was fitted and enough force was applied to bend it.there are  corresponding marks on the pump face as i pointed out to tunnie at the time and a wear groove on the tc half way around the spigot.luckily i had a spare hanging around at the time

Hmmm....I know some try take a short cut by bolting the torque converter to the flex plate (6 bolts which are fitted one at a time through an opening for those not in the know) and then hope that it engages with the pump when the box is offered up....I guess this is the consiquence of taking that approach.

Its easy to imagine the force that the bellhousing bolts could apply.

Is the flex plate ok though?

nothing obvious was noted, i always have a gander as you can see a lot of potential issues not visible when the box is attached. the irony is i only changed the tc as i was concerned that the wear groove would cause the seal to leak so i cured the problem by default.

Why would bolting to flexplate before fitting box save time?

Because, the 6 bolts are harder to fit once the bell housing is.....and if swapping the boxes it means you can realy cut corners and not bother to remove the torque converter at all.

Admittedly, tractors only have 3 bolts, but even so, its hardly any hassle....   ...and I've had my fair share of doing this due to engine changes....

try doing it on a 4 pot its a complete b**tard,when you take the tc bolts out they can fall down behind the flex plate. not a problem on removal but a right royal pain if it happens on re-assembly

I've done this job a few times - and I find it much easier to place the TC in the box, and then offer it up, bolting it to the flex plate when the bellhousing is offered up. Obviously you line up the TC and the plate so an initial bolt hole lines up, and from there it's fine and dandy - as long as you don't drop a bolt. If you do - then you could be popping the box back again!
