Thanks gents. I refurbished the engine (mostly cosmetic, ran perfect except for worn out water pump, replaced gaskets and seals); these Ford industrial engines are tanks.....they sure made them to last!













A lot of elbow grease and Ospho (convert the residual rust the wire wheel couldn’t get off)....and that sweet baby blue Ford paint.

Finished the diamond plate today ......cut two slots for the Control handles using the CNC mill, bolted the plates down....good to go! Was able to hook up the fuel line from the pump to the carburetor....now to start on the wiring. Having fun!

Oops....what’s this muffler doing over here? Forgot to put muffler back on when installing engine (was waiting on flange studs). Lifted engine off rear mounts, quick fix. Having fun!

Got the transmission shifter put together, gas and parking brake pedals hooked up (almost forgot the little spring on the brake pedal), ready for wiring! Getting there .....having fun!

The engine is running! After I installed the new HEI distributor, found TDC on #1, backed it off 10 degrees.....no fire! Realized I had the wires two cylinders off (before the rotor).....moved them all clockwise 2 positions....fired right up! Set the spark gap, fuel/air mixture......runs like a top!

Got one of the tracks on (minus the drive gear).....used muscles I didn’t know I had. One more to go, should be ready for a test drive!

Having fun!

It runs! Got the tracks on, tightened them up, fired up the engine.....drove the machine up to the house. A couple more items (finish wiring the cab, install, mount plow and hook up hydraulics)....and she’s ready for next year! So....what to work on next....





How about a Bombi? Found this beaut at an auction in Indiana (was owned by the IN DNR)....really good shape. It needs some TLC, but on a cursory run.....great little machine.

Curious
Can you fabricate a steel mount for the tranny???

Castings are notorious for cracking

Sweeet.

Well if the original casting is broken then building one from a steel fabrication and machining it certainly might make the long term durability much better.

I would not attempt welding it.. the durability of a welded casting is sketchy at best.

Doable...yes.. long term..not so good.. and that part is a mission critical item and likely tough to get to.

Plus when it breaks it will not be in a great place...like a warm summer afternoon in the shop.

Castings have their place, but after looking at where the ear was bolted to and then broken I would consider it a plus to get a good steel unit in there.

Just sayin...

Having machine tools makes these big projects far more fun.

I don't have a CNC but do have a 9 x 42 Bridgeport with a DRO on the both axis of the table.

Haha.....I truly love working on these. Resurrecting (or improving) what others look at as worn out or from a bygone era is my passion.

My first big project was a 1974 Galion 150 crane. It took 3 1/2 years, a ton of time and $$$, but it was a journey worth taking (still figuring out what Iíll use it for).




I recently considered this as my next project, but with parts rarer than hens teeth and a width larger than whatís legal for transporting (and the lack of an ability to transport it)....its something Iíll likely take a pass on.



Having fun!

When I dig into the Bombi (likely in the fall), Iíll circle back on this. Thank you for the heads up. And a Bridgeport is good as any CNC...just takes a little longer (some of the smartest people I ever met/worked with were Tool & Die makers......whom I learned machining from.....on a J mill and Leblond lathe).

Me too.

I started out in a machine shop that operated solely on WWII vintage machines.

The co eventually got some 1960's vintage stuff and then about a year before I left and started my trucking company they invested in a couple fairly new (Then late 80's) DRO equipped Bridgeports.

Learning to do machining the old school way teaches skills that are all but lost today.

Today's big shops generally have setup people and then operators or part changers to sit and watch the machine.

I have only been around a CNC a tiny bit.

My dad was a tool and die man as was grandpa.

Dad was the night maintenance lead for Continental can company in Portland, Ore when I was growing up and I learned soooooooooooooo much machine shop tech stuff from him.


AS you have the original cast part it will be easy to measure the critical dims and then fab up a suitable replacement with some extra material in the places that's needed

I was thinking about the FOOT that has the crack.

Making the pad longer and adding a nice set of gussets to strengthen the area.

If possible can you post a piccy of the complete adapter ???? or whatever Bombardier calls it and I will take a good look at it and maybe I can offer some ideas as to what might work well.

JUST AN OFFER

I was looking at the Diffy pics and the info on the bands.

I am using a Weasel rear axle in my van cat and there is little doubt that the bands will need to be relined.

I will give Steve at Mn Outdoor a call Monday and open a conversation on the subject.

There is a good likelihood that he can help me out.


Your project is looking great...

Always nice to see a piece of equipment put back in top shape.

I love the pix and the more detailed the comments the better.

Got a good deal done this weekend.....cab is wired and on the machine! I went with LED lights front and rear.....might add some Whelen Hazard LED’s for “effect”. Having fun!

Gas tank is on and Hydraulics are in! I’m hoping to have the plow on in the next couple of weeks, engine cover on....and button this fun project up.




Found a really good inside dome light for a great price. It’s made of aluminum, well sealed lense....could be used outside! I like it so much, I put a review on their website.

Whatís a good hydraulic fluid to use for the plow hydraulics? The manual is calling for Dexron, so assuming a modern synthetic ATF ok?

Thank you

Looking very good!

Yes ATF dextron/ mecron works good in hydraulics
