Hello Patrick are you talking about the flywheel/ring gear plate to block clearance? I actually did this yesterday when i fitted the assy together on the 3.9 I am fitting to my Rangie.the measurement was from the manual.... Check the setting height. Drive plate setting height A = 8.08 to 8.20 mm. which is adjustable by different shims. I fitted the original shim I had and did the check and it was 8.1mm so Ok. However I got to thinking that it is a very small tolerance for such a large amount of metal that is going to be attached. I remember when I undid the torque converter bolts I could spin the converter with the old motor and gearbox in situ, when I refitted with new different motor I could do the same but as far as I could see there was about half to 1 mm clearance between the driven plate and the converter so how can u stuff this up by putting in a new motor? You would have seen or felt something not right when you tried to do up the converter bolts surely? Was the converter removed when this new motor was fitted? I really think that what you are being told is crap. the motor lasted 9k so in that time if something was not right u would have seen or felt something. I have heard of the torque conv not sitting right when the converter was off when the motor and gearbox are mated but this stuffs up the pump gears therefore making the vehicle not drivable in the first instance...,not 9k later. I did not remove my converter and I know it did not move as I marked it! I would fight this as far as I could go!! Who gave you this opinion anyone I would know here in the west? if you dont want to say here ring me 93902957 Brad --Previous Message-- : Hi Blokes : As you probably now know the "NEW" : 4.6 engine which has done an astounding : 9,825 Kilometers and now shit itself (a real : piece of endurance work). We had the autopsy : done on it today here in WA instaed of : sending it back to Victoria to where I : bought it from, it turns out that every main : bearing except for one or two has had : something through it and the rear thrust : bearing on the crank has about a millimeter : of metal missing off it's surface, most of : the big ends are stuffed as well. : Although I have not yet discussed the : results of the autopsy with the people I : purchased the engine from to any real depth : it appears highly unlikley that it will be : claimable on warranty. Being that the rear : thrust bearing has failed which they say is : due to an "EXTERNAL FORCE" being : applied to the crankshaft from the gearbox : side and that I probabably have not coupled : the motor and gearbox together correctly : which is not true as we check and double : checked the measurement for the proper : clearance. : : Anyway at this point in time I would like to : know if any of you have bought a 4.6 motor : and had a similar failure with it. : Please get back to me if you have as I am at : a loss (so is the autopsy expert) as to what : has caused this failure. : : Regards:- Patrick M. :
