904 Transmission Stopped Going Into Gear
Buying another transmission is not feasible for me, I am going to go ahead with this rebuild if for nothing else than to learn.
So on to the next issue I have.
I bought a replacement front drum because mine was scarred on the OD. The drum I bought was a "4 friction" drum from a v8. I got this due to recommendations to upgrade from the 3 disk drum in my 904.
Therefore I also bought a rebuild kit with 8 friction disks total (4 for front 4 for rear).
My issue is that the kit had 4 thick frictions with slots on them and 4 thinner frictions that are smooth:
My rebuild kit came with 4 of each of these.
The new smooth frictions are significantly thinner than the new slotted ones.
My old front drum used 3 "waffled" frictions, so I figured I should use the new "slotted" ones in my new 4 disk front drum:
This is what was in my old front drum. 3 "waffled" frictions.
So i put all 4 of my new slotted thick frictions in my new 4 friction drum and the clutch stack is too thick to install the wave lock ring:
This is my new 4 disk front drum with all 4 of my new thick slotted frictions and new steels. There is no room to install the retaining ring.
Out of curiosity, I installed just 3 new thick slotted frictions (and 3 steels) in my 4 disk drum:
This is my new 4 disk drum with 3 new thick slotted frictions and 3 new steels. The groove for the retaining ring is exposed and installs easily. The largest gap between the wavy ring and the front steel plate is right about what the book says it should be for a 3 disk setup.
What am I missing?
Did someone sell me a 3 disk drum instead of a 4 disk like I asked for? 3 new slotted frictions looks like it works fine...
Do you use the 4 thin smooth rings in the front drum? Pretty sure the old rear drum had the smooth frictions. The old front drum had the waffles...
Thoughts?
BONUS:
This was the most frustrating 45 mins of the entire project so far. I know there is a special tool but I am very stubborn. Finally got it but it was no kiss on the cheek.
