so i definitely need a torque wrench with a dial indicator,correct

Yes get one with range of 0-75. You need one to do lower units too All out drive work you will using 3in lbs to no more than 20 in lbs. So thats why you want to get the one that only goes up to 75 or 100 they measure in .001 The scale will read 0-75 in each direction. 0 will be center and it will 75 thousands each way

When the input shaft assby. is tighten back in to case the gears will mesh and the +&- will line up perfectly with lines. Turn the shaft a every 180 degrees of the For. & Rev gears the marks will come up and be opposite. OK if you put together with + on top
& - on bottom and turn input shaft the marks will appear again half way around as - on top & + on bottom, keep turning a other 180 and the marks will back were you stated+ on top & - on bottom. If there are off pull input shaft out enough to reline. Its easier than it sounds good luck

Thanks for all your information. By the way it looks I have the +/- lined up right. The book says it will be close and it is. I am going to get a a torque wrench at work tomorrow to set the pre-load. I am pretty sure we would have them in the power plant.

Make sure you check the chart that shows the torque for the carrier retainer nut. Its 200 ft lbs so a 21 inch torque wrench on the merc carrier nut tool is 127 ft lbs. Mearsure your tools than ceck chrat.

I will do that, I saw where it said that in the book, I can't get a hold of the turbine manger yet to take a wrench home, he won't answer his phone

Can you believe they don't have one and they did but threw it away several months ago. I just ordered a precision 0-100in lbs that way I have one, when I called about getting the seal replaced they wanted a bunch of money so I figured I would do it myself. I saw how the shop tighten the spanner nut up when I lost the lower bearing carrier they beat on it with a hammer

Believe it or not thats the way the retainer nut was tighten years ago. The spanner wrench didn't have a place to put a 1/2 drive torque wench. Mine is beat to hell. When they came out with torque specs, I drilled hole in my spanner and welded in an old 1/2 socket so it could be used with torque wench. Starting to show my age now. Now with your new inch lb torque wench you will be able to do TRS's, Bravos lowers and rear ends. Use the new wrench for rolling torque only, by a cheap Craftsman in lb click type for the small bolts in the drives. Remember when spinning the wrench checking bearing pre loads the needle shound have a smooth reading if its jumping around a bearing or bearings are probably bad. Kinda feels like the bearing is sticking

I have this back together and took it for a ride, It shifts perfect and seems to run ok I drove about 7 miles and it seems ok, no noise just don't trust myself since it was my first time. Do think it is ok?
