Is there a sealed bearing that I can swap out for the tapered bearings without requiring machining of the hubs?
-
I have the tapered roller bearings in all wheels. I hand packed them throughly then I did add alot of extra grease into the hubs which is what the both of you have stated not to do.... Thanks for the replies
-
I have only 95 hrs on my Savannah S now and I have had to clean the wheels of greesy dirt. It appears that the bearing grease caps do not seal, so grease comes out on both sides of all three wheels. The caps are just thin metal caps without any rubber seal. Are you having the same issue or did I not install them correctly? Thank you in advance for your response!

Thank you for the replies.. You guys have always been helpful! I realize that Savannah flaps are more than adequate but the Checkride requires this maneuver so I will need to practice it before hand
-
I examined the POH and there is no mention of SLIPS WITH FLAPS EXTENDED as prohibited, only acrobatics are prohibited. I will need to practice this for my upcoming certification checkride. Will you please share your experience with this maneuver. Thank you.

Thanks again for the suggestions, these do help. It's the little areas that are easily overlooked
-
Thank you all for the replies I will continue looking....

Hello from sunny Florida! I finally got my S up in the air without the overheating issue. She is a wonderful flying aircraft! I have a whistling sound that I cannot locate so I thought I would ask the forum if you encountered a similar issue and where it was located, and how you were able to remedy it. Many thanks again and again Bryan

I will do just that after several more test flights, thanks
-
Flying two up in my Savannah is requiring nearly full down at 70 mph similar to your Savannah, thanks
-
Thanks for the response. I am needing more than a few bars but it is good to know that down trim IS necessary
-
I have finally been successful in getting my first 40 mins of flight 😁. I had issues with overheating but I believe to have solved it. coolant pump. My question for the group is regarding level flight and elevator trim. At 70 mph, level flight, I am needing to use about 90% of my Down trim. My MAC 29% to 30% right in the middle as required. Is your Savannah like this? With down trim? If not, then how much trim are you needing to set? can I compensate with more down thrust at the engine mount? As always, thank you for your support! Bryan

I agree on the excessive slot width for the bolt size. Truly appreciate the heads up on this potential issue
-
I really wanted to use the Zenith pucks or the Viking springs but that would have required me to change ALL support brackets for the nose gear. So I'm stuck with the Bungee
-
I reviewed the parts list for the 701 and it showed just one circular plate at the top to be bolted on. I believe the difference in the two designs is at the lower support. The 701 nose gear rides on the elastomeric centering block whereas the S rides on the upper axial bearing. Correct me if I am wrong.

SM025 installed as per the manual so i thought. In hind sight, the SM025 should be as flat as possible so the two A5 rivets nned to be removed. the foward edge of shelf needs is also contributing to the tilt of the SM025 not good.
-
The top of the nose gear tube is not square to the shelf. The forward is lower than the aft by about 1/8 inch. The other builder hear stated that his nose gear was similar, not square to the shelf. The top of the nose gear is not flush with the shelf either. It currently sticks up about 1/16 in the front above the shelf which is SM025. When all other parts are in place and tightened down, this will preload the nose gear tube. I have a thought that the powder coating may have caused this issue. I had to grind the upper and lower metal supports to get the nose gear to slide up and down. The bearing could have been binding on the nose gear tube as it moved up and down.
-
Here's what the original install looked like as proof that I installed it correctly. LOL
-
What if SF327-4 were thicker/stronger, would this prevent this from reoccurring? Why do we use this roller bearing in the first place? It does not seem to be designed for IMPACT loading.
-
This is a pic of the top of the nose gear tube (lots of grease)where SF327-4 is bolted So the impact of the nose gear tube retracting from the bungee tension deformed SF327-4 enough to allow the top bearing plate/ring SM003 to slide aft exposing the bearing.
-
An both the SF327-4 and the upper bearing ring SM003 are bent
-
As you can see, the bearing is toast
-
Here's my damage assessment. Somehow the SF327-4 top plate(bolted on) allowed the top bearing plate/ring SM003 to move aft which then impacted the SM002 keeper bracket.
-
There isn't much of a cage for the tiny rollers. The nose gear tube pushes up and down through the center of this roller cage. I am flying off a grass field so the nose gear is working hard( lots of up and down). I can hear the nose gear bottoming out as it slams into the top metal plate stop where the two top retention bolts are located. I cannot avoid this hammering, the field is not perfectly flat.
-
Hello guys. I am doing my initial flight testing and discovered a few roller bearing pieces on the shelf of my firewall. I believe they are from the flat roller bearing of the nose gear. Anyone else have this issue? The nose gear still Rotates without binding.
