hello all
my getrag tranny broke , 500 miles after i bought the truck with a 'rebuilt' tranny. was shocked to see the ruined input shaft pilot bearing surface. lousy design. here my question: i want to buy the absolutely best bearing for the job. gleaned from studious study that it's a timken bearing. is this true? and if i approach a timken bearing supplier, what part number/code would i give to get the right bearing? there ain't enough left of the old bearing to glean any info from. also, if i end up buying 'koyo' bearings which the better kits seem to have, are they really inferior bearings? i posted in the emergency section since i need my truck back soon, so i need to buy bearings soon. thanks in advance.

i wouldn't hesitate to use koyo. some of the best bearings in the world.

 

my input shaft got eat. while tranny's out i am going to replace clutch pilot bushing - there seem to be the options of bronze or NAPA sells a nylon-kevlar one. i don't really like the error part of trial and error, so is there anyone out there with an informed opinion on the kevlar-nylon thingy? for one, i don't see it eating the input shaft, but will it last???
also, i want to get the best possible output shaft pilot bearing. is it a timken, or are there better ones? and what timken part number would it be?
thanx in advanz arvo

 

Get the flywheel machined for a ball bearing and never worry about it again:

Amen...

here's some more info.

Sounds like a bad pilot bushing took everything out.

Mine is whatever SBC puts in their CON-FE kit. The bearings inside the trans were made by F A G in Germany and have stayed together for 40k so far. They were what came in the rebuild kit I bought from Zumbrota Gear. I know other folks have had good success with the Koyos.

 

i use the bronze bushing in the flywheel works good, i wouldn't use a bearing because it will lose its lube and lock up.
anyway how often are you sitting there with the clutch pushed in? most of the time the input shaft is turning with the flywheel

 

How many miles before a person can expect their Getrag g 360 to die ?

To the OP: 500 miles since rebuild, that sounds like it should be under warranty, no ?

 

Wow... How much wood could a Woodchuck chuck, if a Woodchuck could chuck wood?

And on a more serious note, with only 500 miles I would hope a warranty is in effect still...

 

The kit I used had Nachi or something like that. The ones I took out were Koyos which i believe were OEM. Both bearings were made in japan. I have almost 20,000 on my back yard rebuild with no issues( knock on wood) I had my flywheel bored and a ball bearing pressed in. If your close to Southbend clutch they can do it while you wait. The surfacing and sealed pilot bearing was a little over 100 bucks and the 1.5 hr drive to southbend. I thought it was a good deal.

 

Well, I've heard nothing but horror stories about these on the internet. Closer to home, my room-mate's is dying, he's looking at $1400 just to repair it, not rebuild, only repair.

Imagine people's disappointment, finding that one of the strongest motors ever put in a truck is mated to this tranny with one of the worst reputations...

 

wow - thanks for all the info!!!
the rebuild was done for the last owner, three years ago. he just used the truck on his farm, never registered it. i bought it three months ago, and i was snowed in most of winter. the rebuilders 'forgot' to put in the speedo gear, so a pitted input shaft face might well have eluded their shifty eyes...
but yes, the pilot bushing which is in there pretty much ain't in there, at least not much of it... the fact that the farmer had neglected to tighten the tranny bolts did not help, i am sure... since i NEVERRR ride the clutch, i think a bushing would outlast the backyard rebuild i am attempting, since my requested bailout millions have not arrived yet... though i think a properly built ball bearing would have to be far superior, just look at what wheel bearings do...
btw, the cheapest input shaft i found is under 90 bucks, almost suspiciously low... are there different companies making those or is it all the same source?

 

i read the 'mystery man' post on the getrag, that's why i wanted to find the timken parts number... and seriously now, who'd want a *** bearing in his tranny lol...
actually, i grew up in germany and F A G is a fine company, but i went to the zumbrota gear website and i only saw complete trannies, no rebuild kits...
wannadiesel, you remember how much the kit was? did it include those shims for the output shaft bearings?

 

I bought the kit off Ebay, they sell as Zbag on there. I think it was around $200, but it's been a few years. No shims included.

I think proper setup is much more important than the brand of bearing used.

 

That question you asked is impossible to answer buddy... I think if you knew a thing about the NV's you would find that they have an equal amount of problems. Most of the time these transmissions go out because of the people using them, not because they can't hold up. Keep oil in them, fix the known issues and don't over drive them with more power than they were intended to have.
