Carson's C-121

This is post #2 for today.  The fuel tank shutoff opening was deburred and a new seal and shutoff put in.  

I got out a like new upper steering shaft and blasted it then cleaned up the part you can see really nice on the lathe.  Fuel tank and seat bracket is all on and lined up.

I also started playing with thoughts for a wiring harness.  I got out a newer harness for the magnums and started going through what was needed and not needed.  I think I can make most of it work without having to make one from scratch.  It will be nice having a fuse block in there too.  More on that on Monday.    

I had a newer magnum wiring harness in the back that will be stripped down and be the basics for this 121.  We've gone from a coil to a stator run tractor so it needs a ground kill for the motor that didn't begin until 1987.  It will also need an ignition switch from an 87 or newer but I have plenty of those in new stock.  The first pic is the basic harness parts needed, the 2nd pic is all the safety switches and relays that won't be needed.  It will however have a clutch switch, they all get that working and wired in.

Some of the pics are how the fuel line is run.  It is the factory setup for the 87 up as well.  The extra clamps in the 3-4 pics are for the wiring harness.  The 5th pic shows the difference between the men and the boys, the size of their fuel line rolls...  Not really, I just use a lot of the stuff so I buy 250' rolls of the Gates Barricade high pressure line.  

The last 3 pics just show the rest of the fuel line run with an extra clamp at the back of the engine under the flywheel cover that's not usually there (6th pic).  It made a big difference in not just being loose and going where it wants as they usually were.  Most of the the original tractors didn't have large external fuel filters either but they should have had so you could have extra protection and see what's going on.  They are really helpful if it dies from or runs out of fuel because it just takes a quick look.  

The last 3 pics also show all of the engine covers on, the new spec decal, regulator installed, and the choke and throttle linkage all hooked up and ready to go minus cables.  If you look closely all of the fuel line clamps are chrome, pretty cool.  

 

Did some painting yesterday.  A ton of DA work was put into these pieces because they will all be easily seen but it paid off, after painting they look really good.  

Most pics are from yesterday minus the one where it's back on the forklift.  I needed it out in the open to start getting more into the main tower and dash today so I can figure out the wiring.  It got a new Toro idler and main drive belt.  The factory paint on the idler isn't as black but it will never be seen from either side after the belt guard is on.  They use less pigment on their black painted parts to save a little, seems everyone is money hungry these days, pretty sad but it is what it is...   

I have more pics from today on the camera but it's time to run, will put them up tomorrow.

Carson and I spent a lot of time on the phone today and yesterday getting some direction on things so now I can get back in gear.  

First pic is the rod that runs the PTO.  The red one is grandads and the black one is off the newer models.  We talked about this today Carson, just already had a pic of the differences in how they're bent on the cradle type engine vs the non cradle on engine.

Next few pics are the newer fuse block bracket and where it goes.  There's a new housing in there to test the fit.  From the factory the nuts were on the outside but I wanted the bolts on the outside for a better look.  As you can see I found something that is close to the block housing but works and looks a lot nicer.  

Last 2 pics are the upper steering shaft in and set up along with the rest of the dash console all bolted in and done.  In the last pic you can see the new fancy self lubricating plastic bushing in the dash housing for the steering shaft, it's red.  It's one of the samples I just got in a week or so ago made from the German company I've been dealing with for many years on most of the bushings used here.  No more freezing up of the steering shafts ever.  

Spent a lot of the day figuring out the best wiring plan to do on an older tractor with a Magnum engine and even newer harness.  After talking to Carson today we have a plan and can go like the wind now.
