PART TWO FOR TODAY
In the second installment you can see the third shaft with three larger gears on it. As the gear cluster slides the large gear can only mesh with the center gear on this shaft. One of the smaller gears will mesh with the gear on the left side while the third gear can only mesh with the gear on the right. The gears on this shaft are fixed so that each gear drives the other two. The gears on this shaft drive the large (bull?) gears attached to the wheels.

So what we have so far is that as the driver moves the handle from left to right the fork slides the actuator left and right. This in turn slides the gear cluster on its shaft which lines up one of the three power gears to the drive gears.

Now if I can just figure out how the engine power gets to the gear cluster. Stay tuned.

I didn't post anything last week since all we did was clean gear teeth. We pretty much have everything clean enough for movement and meshing of all gears.

Note The pics are out of order. Sorry.

Today we drained the oil and replaced it. After some more work on the carb we wanted to try it again. After a few attempts and some consternation we held open the governor shaft which allows the gov butterfly to open and voila! it ran. The smoke in the shop from burning out the oil we put in the cylinders was so thick other guys thought we had a fire. But as soon as we released the gov shaft the engine quit. Time to tear apart the gov. We called Buffalo-Springfield and asked for the parts dept, but we were redirected to Sears. So, we were on our own again. In the two pics there is a left side which shows where the gov is driven by a bevel gear off the cam shaft we assume and that activates the gov which is in the cylinder in the second pic. Inside the hole to the right is a brass rod which controls the butterfly. We thought there may be a broken spring giving us trouble, but after cleaning and disassembling it we found it is simply out of adjustment. Should be easy, right.

Not ! All the parts inside the gov are pot metal and after many years have started to deteriorate. There is a screw which when turned adjusts a lever inside to put pressure on the brass rod therefore holding the butterfly in the proper position. Pretty much eaten away. JB Weld to the rescue for now.

NOTE After the gov was off the roller the canister in the right pic was able to be taken apart with two screws. While on the roller we thought it had to have 4 rivets ground off to open. Every once in a while... .

This week because the governor is still under construction, we moved on to the radiator. After removing it from the roller we took it apart only to find that the tank bottom is broken. We hope to test the tubes which are brass and if okay we will either get a new one cast at Cattail or fabricate one out of steel.

As seen in the pics there were two lug cast in that were drilled and tapped for studs that held it in place.

Yes, Andy. Progress is slow, but steady. What doesn't get done this Monday has to wait till next.

Lester stopped by this morning to pick up a quarter 32 tap to finish this piece he fashioned. The darker one was the original pot metal he glued back together as a pattern. The small hole is what is being tapped which gives some indication of size. This is the control for the governor. It is adjusted by a screw from outside.

Curious to what happen to this roller that I took a pic of in Washington NJ few yrs back at an auction. I believe the owner was a member of JT back then. Little different than the roller you and Lester are working on i believe.

From the pic it is more alike than different. The large silver tank on top is a replacement for the gas tank or it was converted to thermosyphon type cooling if the radiator was bad. The brass tag under the stack is at the same place. It is the patent info for the frame only. I'd say they were the same except maybe for size.

This may be the one that was owned by Washington NJ street dept.

We've spent the last two Mondays working on the radiator because as we were putting the repaired gov back on the dicast collar which attaches it to the engine turned to dust. Lester is making another housing for the gear and attachment collar out of aluminum. Should be done this week. In the previous pics it is the elbow on the left.
I wonder if they knew the lifespan of diecast when they made these parts?

Probably not. There are many alloys of zinc, some last a long time, others seem to disintegrate after 30 years or even less. Zinc is a weird metal. Trying to cast or even work on it can be problematic. Casting it makes it generate internal stresses which eventually lead to self destruction as many a mag and carburetor owner can attest to. Good to see that you have a machinist that can make new parts for you. Just hope the aluminum he uses is up to the job! Too soft and it will deform with vibration,and too hard and it will break (brittle). Hope to see you monday!

I've been told it is time to make an update or people will think we have stopped working.

Not the case. The governor is fabricated and put back on and actually seems to work as it should. Now have to say this is by hand turning since we have other things apart so the roller can't run. So now the entire fuel delivery system and the gov. is rebuilt and back together. A new gas tank was made and installed today. Next week we will connect the lines.

Before installing the rebuilt radiator we decided to take the water pump off and repack it. Good thing we did cause the shaft that starts at the back and is gear driven was badly pitted and had to be replaced. This shaft drives the water pump and then continues toward the front to drive the magneto. This was also put back together today. When replacing the radiator hoses we noticed there was a build up of rust and debris from the old hoses. We decided to flush out just the engine so nothing would be forced into the radiator. Once again luck was with us because we found a low point coolant drain with a leaking gasket. What a surprise. When the plate came off that was also packed with rust and etc.

The day ended with cutting and bending an exhaust pipe. There is a muffler inside the smokestack. This should be welded up by next week and be ready to put on.

No pics today because they kept me too busy working. I'll try to get some for next week.

A lot of headway was made yesterday. The cooling system is complete except for filling. Probably plain water first for a good flushing then antifreeze.

Pics of Hank gas welding the exhaust up the exhaust pipe. There is a muffler inside the smoke stack that is original. See how it sounds.
Getting back to the 2 steps Foreward, one back. We were putting the gear safety shrouds back 78on and a wrench was dropped into the nether regions. Since it was the end of the day it was a good time to stop as long as we remember next week.

After last week's success we had high hopes for yesterday.

We finished piping the fuel lines and filled the tank. We filled the radiator with water only to check for leaks. Couple seeps which we hope Barrs Leak will take care of. Since there is an OC3 crawler between us and the door we jacked up one side and pulled the drive pin on the other wheel. Hooked up a battery and were are ready.

WE'RE GONNA START IT!!

Started turning it over. some spittin and sputterin, Gas running out on the floor but no running. Let the battery rest and tried again. Same result. Seems like it is out of time. Walked to the other side of the roller and checked our self-determined marks. Nothing lining up. Either someone turned the crank while the shaft for the mag was being reproduced, or the gremlins did it, or we are just plain stupid. (I'd prefer one of the first two.)

So next week we start all over again with the timing. The way this is going the others will get the crawler done first. Nah, probably not!

Hard to take pics of frustration.

Well, we had a really good day today. Only some of it can be seen on the link below. Hopefully you can adjust the size to meet your needs. I am certainly not competent when it comes to camera work, but I can make a mean hot dog.

Not too much happened yesterday due to the swap this weekend. We did route a choke cable and loosened up parts on the sacrifier though. Not sure it will work, but we will try.

Does anyone know what and where the air cleaner might have been.


They got the OC 3 running!!!

This morning they finally moved the OC 3 out of our way. Twenty minutes after they started up and .moved out, we followed.
Bring on the doubters. Sorry again for the shoddy camera work.
