D2 drive sprockets & steering clutch press ????

I am wondering if these 15 and 20 ton specs are needed ???

Yes they are but try them at 10 and 15 tons first to see how far the splines have gone up to where they were before, its easy to go too far as well. I know some people warm them up and sledge them on but this makes me cringe, you don't know how much or how little pressure you have on and what is happening to the seals? The most common cause of loose sprockets and hubs I came across as a service engineer was not using the proper tools.

Thanks for the info was able to use the local mechanics 20 ton porta power worked out great
