Topic: HELP ME PLEASE W56 rebuild, chipped 4th gear on the input shaft side

[BoG-ToY]

updated...  put a SMALL chip in fourth gear.... like less then 1/8" of contact area lost on the far edge... should I polish it out and run it... or replace it? let me know what you think, I will try to post pics later

[zippo]

I made these tools todo it. I used long 12" bolts with nuts to pull it. Work great! Slipped the u-shaped plate behind and used the top end of another puller looks kinda like =====O=====!!!! Make sure you take the c-clip off holding it on

I know there is a SST to pull the fifth gear off the output shaft... I dont need that one

sorry man... I figure that ones easy to make, Im trying to find out how to pull the clutch hub number three, its the one with the thin steel plate on the back of it, looks like an oil slinger or something on the back side but its to hold the little springs in place on the hub since normally there would be another synchro on the other side....


see the red coloring on the FSM pic? thats the part Im looking at pulling

[emsvitil]

I don't think I had a part that looked like that on my W56B..........(unless mine wasn't exactly the same shape as shown)

I got away with using gear pullers, hammers and brass punch to get everything apart..........

[BoG-ToY [OP]]

hammers and brass punch actually work really well... lol
I broke my puller trying to pull it on my last tranny.
I will take a picture and get it on here as soon as possible

[BoG-ToY [OP]]

SO, got it all apart.... dont know where I was having the problems, I just remember damging that peice last time.. But I went out there... step by step and it came apart no problems... thanks for the help guys... will post up more when I need more help

[zippo]

GREAT!When i took mine apart that oil slinger was damaged and i had to use a hammer to reshape it. Enjoy!

[BoG-ToY [OP]]

no damage to mine at all.... mainshaft center bearing had .109" of "endplay"   craziness

[BoG-ToY [OP]]

new problem, chipped a gear... ALSO  still looking for the little reverse lockout pin as mine is broken, let me know if you have one you'd sell cheap

[zippo]

I bought a crapped out trans from a scrap yard for $75, for hardware, and just used the best of both, anywhere else is big $$. ille look and see if i have any left, but prolly not.

[boggerunner]

ive got a w56b with a bad input bearing, id sell the whole thing for $50, or pull it apart and sell u parts, let me know.

[emsvitil]

Show a picture of the chip.

At the edge you just need to dremel it so it's smooth.



Also search for 'chip tran' , there's a couple of other threads about this........

[BoG-ToY [OP]]

gotta love macro mode... lol

[emsvitil]

Looks like it's not in the contact pattern.  (it's not a #5 above)

I'd just smooth them out with a dremel so there's no possibility of crack proprogation

(and get rid of the pits on the other side)


BTW, I don't think that's 4th.....  4th is direct drive, no load on countershaft

[BoG-ToY [OP]]

you know... your right.. that must be third... lol its whatever is the one ON the input shaft.... but your are absolutly correct. forth is the lock on the end of that gear 1:1 so no gears engaged

[zippo]

I would never use that. You are putting the time, energy, money into why risk it. I would spend the cash and replace that broke ass gear. You cannt see the little micro fractures and the last thing you want is that thin edge to brake and destroy your hole trans.

[BoG-ToY [OP]]

so what would you do? break in a new input shaft?

[BoG-ToY [OP]]

Im kinda needing to get this thing done.... IF I am doing a new input.. I need to get it done. as well as find a replacement reverse lockout pin....

I may just CLEAN that bearing as it feels alright... and run it till I can replace it..... but who knows.. if I could find a new input for CHEAP I would run it

[emsvitil]

Is the chip on the drive side or coast side of the gear?

Coast side I wouldn't worry.

Drive side, just for paranoia, I'd put some grease on it and run it thru and see how the contact pattern is and feel for any roughness at that spot.

[BoG-ToY [OP]]

thing is on a helical cut gear like that.. you wont be able to feel it.... it probably makes up 5% of the contact area or less. that and I will have to put the entire tranny back together to test it out and I dont know that it comes back apart when you are done. I beleive that in order to get a good test of smoothness it would have to be reassembled with the new bearings (old ones were so far gone it wasnt funny)  once together that may be the ONLY peice that will come back aparts, although it might not come back apart. because you have to clear the synchro cone for fourth gear and I dont think stuff moves enough to do that

[Yota87Truck]

I would either leave it as is or replace it with a part from another trans.  It's too expensive to buy a new gear.  I would personally just leave it.  When I rebuilt my trans I busted up a 5th gear.  I just used a 5th gear from a spare trans.  But if I didn't have the spare trans then I would have just left it.
