need help what is causing the noise

Yeah i think the d 18 is good , i feel it is the transmission . i will replace all the seals in the t case and rebuild the trans .

 

What do you think Glenn? rebuild trans and reseal d 18 ???

 

Parts are ordered . I have Pictures of the gears .

 

Remember that the T-90 and D-18 share gear lube so the flakes in the transmission have also gone through the D-18. At minimum the D-18 needs to be completely taken apart and cleaned thoroughly.

 

Yeah that is a good idea Walt . i have it out so why not .

 

yep two areas I would look at the intermediate shaft and the front output shaft bushing

 

ron do you mean the front output shaft bushing in the transmission?

 

no transfer case , it's a bushing that's in the front of rear output shaft. while its out . you still have to disassemble your transmission for other issue

 

ok thanks

 

T case bushing is good Twin2. I got the trans out today and on the bench. It needs 2nd gear and both bearings replaced . There is a lot of grit in it i will take it to the local machine shop and have them solvent wash it . So far that is it

 

here is a video of the front output bearing the rear was worste! front out put bearing

 

Some Pics of the transmission You can see 2nd gear syncro are ate up gear is good

 

Yeah and the back was just as bad . i am going to flush the d 18 and double check for any metal in it !

 

I just got done doing this myself.

The large kit has the two sets of roller pins and two unsealed bearings 1.375 ID 3 1/8 OD plus THE two syncros and other goodies LIKE ALL THE GASKETS.

go to u tube UNDER T90 REBUILD, there is a video guy who used the novak kit with the sealed front bearing and that is a good start for where you want to end up.

If you did not go novak for parts (Me jC Whitney had a Crown kit for $75 SHIPPED)
there is only 27 minutes on the video of 39 minutes that are specific AND relevant.

Your photos were not showing an exploded tranny just some worn out bearings in my opinion, change the clutch and throw out bearing too, so that they cannot be the next reason to tear it all apart again.
Consider synthetic gear lube/oil. Any gear that you remove consider glass beading it spotless and then dunk tank in cleaner solvent prior to re installation.
Air blast, compressed air, all oil paths, everyone, always, within the gear shafts and threaded areas in the case and all the gears too

You are having all the fun now!

 

I am on a very tight budget . I got the rebuild kit from Wacks. I will take some better pics . I just got second gear brand new . i need to have it running by may for my sons graduation from high school . I will post more picks . Right now i am healing from surgery on my right hand ,carpel tunnel release .

 

Well i found what was broke . It was the oil collector in the transmission didn't notice the broken piece till i went to pull it out for reassembly .Look at the pics in post 54 . you will see it clearly
