This is the kind of stuff that keeps me going when I get bogged down.
Underneath the mud, grime, and several coats of house paint, handy open
garage paint, and general abuse, rests the heart of a warrior,
waiting to be remembered.
Having rebuilt the tranny it's time now that the weather has broken here in Central Texas to get that D18 back together.
A couple of months back I tore it down and eyeballed everything and with Oilleaker's help diagnosed what needed replacing.
Below is one gear and the new one that folks just doing theirs might use for comparison. Note the rounding off of the points and all the forward sharp edges rounded down, although there is still a lot of meat on that smaller gear.
Several gears in the tranny and the synchro teeth and blocking rings were well beyond what you see here.
So installing the innards and bearing caps to check bearing preload.
Read all three versions of how to rebuild the D18 and still missed why
you want to start with too many shims. Rick says start with .060.
I had .057 and snugged it up.
Now need to pull everything back apart to give the mainshaft a little
room.......
A20b. Now here is where you start adjusting endplay. You should have a shim kit, a collection of various thickness shims that are used to adjust endplay. The shims go between the rear bearing housing and the D18 case. They are pre-cut to fit and come in a "variety pack" of thickness. When first putting the D18 together you want to install too many shims so you don’t damage the bearing and or seats by over tightening them. I have found that a good starting point is a shim stack of about .060 or so. **
A20c. Carefully tighten the rear bearing housing into position. You should be able to feel endplay in the shaft. If at any time the bearings start to bind or you cannot feel endplay, stop. You don’t have in enough shims. **
Hey Brian,
Just concerned that you don't lose interest....when the going gets tough, the tough get going! At least that's what I often tell myself. That, and "patience, grasshopper..."
