Getrag syncros

[Flat bed cummins]

Ok guys I'm new to this forum I just got a cummins and wanted to know your ideas. I've been looking around and found some kits for the getrag that come with the synchros and bearings except the needle bearing but my question is how easy will it be to accomplish this task? What do I need to know, could it possible be the shift fork cus first gear can be hard to get into as well, all advise is appreciated.

Could it be the shift forks? Cuz today it didn't want to go in first or second, just was grinding then all of a sudden it went in

Can't say that I can personally give you any advise, but Ellis did a great write up on this a while ago.

Here's the link. viewtopic.php?f=3&t=12097

Hey Hey just seen this tread,I've been out of pocket lately. When mine did as yours is,it was the pocket bearing. The bearing in between the input and the main shaft,it holds the shafts in line with one another. By it wearing out the input it causes the front of the mainshaft to drop resulting in a (for me) 2nd gear that was a beooch to get in. One other thing I had wrong with it is that I noticed a binding feeling in reverse when backing down hill,that was weird and kinda hard to explain.

Well I haven't backed down a hill lol did you replace the bearing? Or got a new transmission

[ellis93]

I replaced the input shaft and pocket bearing.....with every other wear item.

It all happened right before I did that tread on building it,same trans

How hard was it to do? I have a press and snap ring pliers, I'm looking for the manuals on the getrag I found 20 page PDF but I want to make sure it isn't missing anything,

[ellis93]

It ain't bad to do

[Flat bed cummins]

So you think I can do it with that PDF file that is on google? Any tips before I start? I have assembled engines and axles never transmissions,

[ellis93]

Farmboy posted the link to my trans build,three post down from the start of the tread. In there is about all I know about this trans. If you run into a snag post and ask or pm me,I will help any way I can.

One more question what is your preferred place to buy rebuild kits I was looking but the ones I found don't include the needle bearings, and would you replace the shift forks? My first gen has 316000 miles so I'm not mad about the tranny and I got it for a steal of a deal.

[ellis93]

You won't get those needles unless you specifically search them out. Folks seem to deal alot with Zbag,google them. I use whatever parts my distributor has,transtar industries.
I'd almost guaranty that trans has been built before with that kinda mileage on it.....unless it was pawpawed around

[Flat bed cummins]

Should I replace those too?

[ellis93]

It's very doubtful you'll need them,only time I've ever seen any bad was with a truck that was towed with the driveshaft still in,with the trans in neutral. That French fried them something bad......along with shaft and gear.....made the trans totally useless.

I'd just buy the w/syncros Kit and an input shaft.

Alrighty, thanks a bunch I hope It goes easy, how long does it take you to finish a tranny from pulling it from the truck to totally installed?
