Dumb Axx

My starter gear chewed up this past week. Can you guess why? I was confused and perplexed till I figured it out. Now I realize it was a dumb mistake. The fact that I post this photo is a clue in of itself:

To give you some background. I have not always been a gear head so to speak. I built r/c model airplanes for a long time. I am not talking about buying planes from Hobby town and flying them, I built planes from scratch.

Often things worked out well but often things did not. It's funny because when things would fail I would always blame the "G)@ DA)# builder (which was me).

But along the way I would learn; and learning and expanding your skills is the fun of it.

Here is a 34lb 100cc 10hp scale airplane built from scratch. The first one I built I planted over a foot into the ground.

The point being.....

If you do nothing you will never do anything. Sometimes simple mistakes which are not that hard trip us all up. SOOO I ask,

What are some stupid mistakes you have made we all need to know about!!??

Ok, I'll take a guess. I see you have a 400 block there; maybe wrong size / # of teeth on the flywheel?

Neat airplane too.

Nope. I'll bet someone has done it though.

forgot to take the tennis balls off?

Well. It was a dumb axx and simple mistake. At least I feel better no one sees it yet.

No..but believe it or not, the answer is in the photo.

Your dust shield has dropped to the right---looks like a dowel pin is out. I doubt if that was the problem since the starter bolts to bell housing studs. Hard to see details.

It's just loose from being unbolted.

It is difficult to see. What kind of flywheel is that? Something looks strange with the surface but it's hard to see in the picture. It looks like the flywheel is on backwards---I have never seen one that could possible be installed wrong or even if the holes would line up on the crank since they are not symmetrical. The gear is flush with the disk surface but there are so many variations of parts now, maybe the flywheel is thinner than normal or the picture is not reading right. Hints? I love puzzles.

Yep, flywheel is on backwards. I still can't figure out how or why I did it. I googled the starter depth/ engagement and that was the first question wich kept coming up. As soon as I looked at it I just smacked my forehead!

Winter is coming up and I have the transaxle out so I am going to get the pinion gear changed. This is a tq based engine with 15" gr4 wheels. 60mph in 5th I need to shift again.

I contacted one company and they said I needed to change my tire to a 17-18 inch tire. I was kind of insulted. I thought no..the car rim and tire is what I want...I need the gear ratio changed.

You are my hero for posting this. And yes I have done worse to the level of double "Dumb Axx"

Looks like the BOO-BOO didn't destroy the any big ticket items so congrats.

If you own a Pantera long enough, $#!T happens!

Sometimes when you branch out to new things simple unknown things can trip you up...so ... what are other simple things that have tripped you up?

My mechanical fuel pump was dead, and on replacing it with a new one, the bolt was a bit difficult to get screwed into the block. Afraid I was cross threading it, I took the new fuel pump off and was trying to screw the bolt into the block to confirm all was O.K., when fumble, fumble, plop, it falls through the hole in the block. I can just reach it with my finger tips, when oh, no... it falls into the sump... So that little exercise ended in a marathon of taking off the sump, cleaning it all out, new gaskets and getting and 3 hours of getting it back on again whilst laying under the car - the clearances with frame rails, shifter rod, baffles etc in the sump, pickup etc meant the planets had to be alligned perfectly to get it on. And following the normal 'whilst I'm in there' syndrome, new heater hoses, shut off valves new radiator hoses throughout, new fuel lines... Good news was, the threads weren't cross threaded and there is not a trace of leakage from the sump gaskets a year later.

I had one of those! Lucky on an engine stand I was turning the oil pump with a drill. I had a socket on the end of a drive. Pulling it out the socket fell off. After an hour of lights and magnets it was no where to be found. I had to disassemble the front of the engine to find it and it still took a long time to find. Turns out it was hiding behind the timing gear. Glad the engine was not in the car.

I welded the socket on after that.

The first engine I rebuilt (at 16 years old, in my defense) I put the caps on the rods backwards. After torquing up the first three or four the crank wouldn't turn. Apparently the stampings on the caps were much more easily read than on the rods. Not realizing they were stamped in both locations, and lacking the experience to know it made a difference, on they went.

Fortunately it only cost me a few bearings, and a bit of pride when my buddies found out.

God, so many where to begin? rebuilt the engine (I am currently on engine #5) 20+ years ago, installed it and something was not right, now you know how long everything takes, I was ready to turn the key and through the windshield, hanging on the wall a single head gasket, NO it can't be
but it was, humility is a learned behavior.

Lol

"No! It can't be!"

I have definitely been there!
