How hard is it to rebuild one of these cases and how commonly do they need it? I'm looking at getting a good used or junkyard 13-56 t-case to replace my 13-45 in my 85 as part of a project to install a US Gear Dual Range. I'm debating if I should try tearing it down for inspection and rebuilt or just throw it in there as is and go. It doesn't seem very common for them to wear out but if I've got it out it seems like it might be worth doing just for piece of mind. Thoughts?

Also, anyone have that section of the manual online or know where I can find it? I've got the factory manual that covers the 13-45, but don't have anything for the 56.

Thanks,

The 13-56 is stupid simple to work on, Ive had mine apart a couple times. If you want to do it id say its a good idea, but i have no idea what replacement parts would cost, I only had mine apart to reseal it.

 

i had a new chain, pump and bearings put in the one i put in my 88 by a friend who owns a trans shop. he did it for parts cost cause he owed me a favor. total cost was $200
