The Mark VII does not use a way tube spacer to position the carriage to the headstock(blade to slot etc.), but instead has a notched rod with three indexed positions. Resembles an arrow protruding from the carriage.
[ATTACH]20884[/ATTACH]
The rod is threaded and screws into the outer(bottom in the pix) side of the carriage. The carriage end of the rod is slotted to enable adjusting the stops. A jam nut secures it in position.
[ATTACH]20885[/ATTACH]
The table height lock nut and crank are similar(smaller) to Mark V 505-520.
[ATTACH]20886[/ATTACH]
The pinion gears are the same as all Mark 5 through Mark 7.

Both pinion gears are merely pulled out from the carriage.

The pinion shaft resembles other models and has a c-clip on the rear end.

Now where have I seen a carriage lock similar to this?:rolleyes:

First the locking nut must be removed. It is shallow and is not easy to move, so a good socket wrench must be used to 'adjust' or remove it.
[ATTACH]20891[/ATTACH]
Once the nut has been removed, I thought the shaft could be pushed out the front. However this stuff said otherwise. The collar behind the handle will not let the wedge pass through it. The collar is 'stuck' on a tension pin. Once it got 'unstuck', it all moved out the front.
[ATTACH]20892[/ATTACH]
This pix is to remind me how it came apart(so far).
[ATTACH]20893[/ATTACH]
And all the stuff in front disassembled. I do not yet understand the handle/white piece/collar function, but do know the handle steps fit against the white piece steps and the collar nibs go into the white piece slots, and the collar fits over the pin in the carriage. I am guessing the white piece creates a stop to prevent too much pressure to the wedges.* That long tension pin secures the handle to the shaft.
* Nope! The white piece provides a camming surface that squeezes the wedges together. The step is a 'loose' stop.

My mystery nubbin has something protruding from it... any ideas what it is meant for?

Looks like a tension pin. I will revisit the carriage tomorrow.Mike vonBuelow wrote:My mystery nubbin has something protruding from it... any ideas what it is meant for?

Since mine also has the nubbin, I assume it was an abandoned design or has something to do with die casting. I also assume a PO put that tension pin in there.Mike vonBuelow wrote:Re: Tension Pin - I talked with SS customer service, she had no idea what it's for...she even put me on hold to ask others - no answers!
i.e. stop fretting over it!;)
Did you really expect folks a half century removed from the initial design to have a concise, accurate answer?:rolleyes:

Re: Mark VII Carriage Breakdown
I think the tension pin is a stop for the pinion gear? See pic
