    Damaged Front Planetary Gear 904?

    So get this. I find someone online that sells them - A&A Transmission out of Indiana. The guys there are great, and I get a reconditioned 3 pinion gear ordered over the phone. I get it in the mail today, and it looks exactly the same as the one I pulled out of my 904 - 'defect' and all. It...

    Damaged Front Planetary Gear 904?

    Thanks guys - kinda what I figured..looked pretty trashed. I'll seek out Torqueflite Patty too. Appreciate it!

    Damaged Front Planetary Gear 904?

    Alright, FABO members..need your help again. My front planetary gear TO ME looks like it is FUBAR, but I want to be sure before I trash this gear. It looks like a ring that would normally be mounted on top of this gear has snapped off, and a chunk seems to be missing from it. So, IF this is...

    5 friction/clutch clearance issue in a 904

    This entire FORUM is invaluable for the amount of help, tips, and advice I've already received..and I'm just getting started. Hopefully one day I'm able to give back as much as I'm getting from all of your guys. I'm going to have the pressure plate machined, but before I do so I'm going to get...

    5 friction/clutch clearance issue in a 904

    The 273 is going to be a mild build at first. I'm thinking of having it bored .030" with the goal of trying to get as much power out of it without going crazy. Eventually I want to step up to a 340. YES this has definitely been a great learning session!

    5 friction/clutch clearance issue in a 904

    Another thing I noticed was that the snap ring was a flat snap ring, and not a waved snap ring like the book calls for. Any problems running this? From what I've read it sounds like this will bang 3rd and reverse a bit harder. Thoughts on this?

    5 friction/clutch clearance issue in a 904

    I took off the snap ring, pressure plate, clutches and frictions. I compressed the return spring module down and removed the single snap ring. I put the double wound snap ring on, and this time it seated correctly. I measured the outer snap ring, and found it's at .076". I re-installed that snap...

    5 friction/clutch clearance issue in a 904

    I'll double check it tonight to see what was causing it to not seat flush in the groove. I definitely need that security with the extra pressure. Thanks again!

    5 friction/clutch clearance issue in a 904

    Alright, so mystery solved. I pulled everything out, dried it off, and measured my gear. The frictions were .061" and the clutches were .068" (exactly what 70AARCuda said). So I thought maybe it had something to do with my new 24 spring return module. The snap ring that I received with the...

    5 friction/clutch clearance issue in a 904

    You guys are a fountain of information. The "1/4 of what you still know" is a million times more than I hope to have under my belt! I've been working long hours b/c my boss is on vacation so hopefully tonight I can get back at it.

    TrailBeast, which drum have you used in the past?

    5 friction/clutch clearance issue in a 904

    Nice Bob! I know it's a long shot, but do you remember what thickness clutches/frictions you used in your set up?

    5 friction/clutch clearance issue in a 904

    Thank you Crackbacked. I'm picking up a caliper tonight to see exactly what I've got (once I dry everything out). With it being as off as it is, it's got to be because the frictions and maybe the clutches are just too thick. We'll know more tonight!

    5 friction/clutch clearance issue in a 904

    Thank you Fishy68. I'm going to dry everything off and recheck when I get home from work tonight. That'll help me figure out where I need to go (thinner material) or just stick with 4.

    5 friction/clutch clearance issue in a 904

    Thank you zijmer. I'm not in a hurry at all, and I already have a wider Kevlar front band from my rebuild kit. I'm going to try to pull the clutches/frictions out, dry everything out, and see where I'm at before looking at machining the stator. I'm glad to know that there is a solution, and one...

    Thank you for the tip, zijmer. I'll back them out and soak in ATF.

    5 friction/clutch clearance issue in a 904

    Tony I think you're right on. There's no way I can get 5 of these thick frictions to work as is.

    5 friction/clutch clearance issue in a 904

    I do, but the drum is packed right up to the snap ring groove without the pressure plate going on. It's roughly 3/16" thick. I think it's got to be machined or I need to scrap the 5 clutch/friction setup. I'm curious to know how others that have made this upgrade have done so. Is it just...

    5 friction/clutch clearance issue in a 904

    Here's a shot of the direct drum with the new steels/frictions. You can see there's not enough room left for the pressure plate and the snap ring. Below is a pic of the new friction (red, on left) compared to what was on there (I'm assuming stock)

    5 friction/clutch clearance issue in a 904

    Yes the direct drum. It's the stock 904 4-disc drum. I didn't know if there was a way to modify the 4-disc drum to accept the 5 discs either by machining or a modified pressure plate. In all honesty my HP application is mild. A 273 bored .30 over with a mild setup.

    5 friction/clutch clearance issue in a 904

    .061 They are thicker than stock though. The clutches appear to be the same (no caliper), but the new frictions are definitely thicker than stock.

    5 friction/clutch clearance issue in a 904

    I'm trying to use 5 clutches/frictions in the front clutch assembly on my 904, and I'm running into a clearance issue. Before the wave snap ring goes in, a pressure plate must first go over the clutches/frictions. With the extra clutch/friction, I don't have enough clearance to install the snap...
