Is that short chain going from the left pring to the right attachment on the tailwheel?

No there are three links hanging loose. It's not the chain.

Your all looking right at it and I bet no one recognizes the 2nd issue because their's is like it.

You guys better hurry up because George is probably dancing like a Mexican jumping bean with anticipation wanting to shout out the answer which will probably be #3 on his newly unveiled and growing personal crusade list.

If only I had realized what kind of damage you were talking about I'd have spent less time inspecting that bolt.

1. The Guard-tailwheel spring is missing
2. The bolt - (Attach guard) is installed from right to left instead of as shown in the IPC left to right.
3. The bolts - (Attach stiffener assembly) are mounted top down instead of, as shown in the IPC, Bottom up.
4. The clip rings that connect the chains to the tailwheel steering bar are installed reversed according to the IPC the should have the open end at the steering bar.
5. The tailwheel appears to be bald.
6. The master leaf appears to be flattened out allowing for improper caster angle.
7. Some kind of non standard hub cap on the wheel (nice fit).

It looks like the left spring is connected to both sides of the steering horn.

Here's the problem when you decide to have a contest. You've got to be REALLY sure there are only 2 things wrong with the installation and then when what you think is obvious is not found folks start digging.

If by #1 you are referring to the missing guard on the U clamp half way down the spring pack, that correct answer has already beed given. I actually thought that answer would be the last.

As for #2 and #3 do you really thing a respected RatPlane owner would have a contest where the direction of the bolt installation was the answer? OK yes I might do that but not in this case.

#4 Hmmm all I can say is the IPC has been wrong before . I prefer to see these links installed the way they are, open end in the sash chain because the sash chain holds them together perfectly. When placed any other way I've seen them pull out or about to pull out.

#5 I could be mistaken but I believe these tires were bald when new.

#6 I don't know. The caster angle looks OK to me. Lots better than angled the other way and besides the only way you would know if the spring was under the proper load to set the angle to be checked would be if the airplane was loaded to 2000lbs. (right George) How would I expect you to know that from this picture.

#7 It's a nice fit because it is the stock original cap for this wheel.

So if your keeping count that is 6 no and one correct answer we already had.

Tune in tomorrow and if I find time while at work in between doing my best impression of an air traffic controller, I'll post the answer.

That is a clever optical illusion to through of folks from the left coast.

Can you find 2 things that are wrong with this tailwheel installation. We are not talking rust. We are not talking extra chain.

George is totally DISQUALIFIED and Bill Kelsall please don't spill the beans if you remember the one thing I noticed and told you at the auction.

One half of the upper bracket assembly part number 0442127 item 20-91 in the parts catalog is missing. And of course the previously mentioned the tail wheel Chain guard item 86 part number 0442125 is missing. The part number 0442127 is difficult to tell how it is supposed to look in the parts catalog but essentially it is the mirror image of the bottom bracket in the picture Item 92 part number 0442124.
Actually I am wrong I just looked at the picture of my tail cone assembeld from a new parts and the upper bracket part number 0442127 is not two pieces as I had recalled.

OK I'll give a clue to second answer.

A wrong part that is there requires a right part to be missing.

Well..you wouldn't think this possible...but I believe you're both wrong on this point. John...the clips are installed as depicted in the 170 IPC. Bruce, the ones in the picture are not installed as you describe your preference. (This comment is based upon the tear-drop shape of the clips. Depending upon the source of the clips, they may have their open-ends at the large ...OR the small ends.)


And John, that is not a hub cap....that is the left half of the actual hub. The hub cap is Item 15 in the IPC.

I'll take another stab, the master leaf looks over sized pehaps L-19.

I suspect not many Members have copies of any IPC other than their own particular model,...additionally, the vast majority of owners have B-models which are completely different than either the 170 or the 170-A .....so here's a comparison...

On the left is a 170 tailwheel bracket as depicted in the 170 IPC. On the right is a 170A tailwheel bracket.

Finally. John got it. I was beginning to wonder if anyone else could see this.

Not only does it have the thicker L-19 main spring, the spring pack only has 4 springs when it should have 5. The smallest spring is removed to make room for the thicker L-19 spring.

I thought it odd that an airplane that supposedly only had 449* hours had a tail spring break, or presumably break, maybe just bend to an incorrect angle, in order that the owner replace it.

*This was the tailwheel assembly found on a low time, very original '48.

Great!!!!

My next guess was going to be the grass needs mowing.
