After talking with my AI, I find I can't simply replace the expander brakes with Clevelands claiming unavailability of original parts. He says I would have to remove them if I ever sold the bird.
Alexandria Air does the Cleveland conversion for the 14-19 Cruisemaster, but according to the FAA, that's not good enough. I need to document the Clevelands using previous 337s from 14-13 owners who have this modification.
If those who have Cleveland 40-97A wheels and 30-63A brakes could send me their N numbers, I can get the FAA records. According to my AI, the more conversions I can come up with, the easier it'll be to get the 337 approved.
Hope to hear from y'all,
 
On another note, have all these modifications been done on a 14-13-2?
Electric Fuel Pump
Cleveland Brakes and Wheels,
Whelen Strobes
Hydraulic Retracts using the emergency hand pump from a 14-19
Poly Fibre (Stits) fabric

Eventually I'd like to pull an "Ozzie Levy" and hang a Lycoming IO-360 on NC74392, but for now my old 150 HP "Frankie" will have to do.
 
Hi Dave,
I do have an electric fuel pump, Whelen strobes, Stits fabric, and Goodyear wheels and brakes (off of a 260). Paperwork for all. Let me know what more you might need since the CD didn't come out that well.
What size axels are you using? I have to have steel bushings for the wheels, since I have 1 1/4 inch axels. Larry
 
I bought a pair of Viking axles (used- VERY cheap) that will fit nicely into the Cruisair strut.
As for the paperwork, yep- I could sure use all you have on the above mentioned mods :D
I'll send you my address off-board.
 
HI Dave,
My Cruisair N86703 s/n 1064 has the Cleveland 40-97A wheel assemblies and the 30-63A brake assemblies that were installed on a field approval in 1989. Send me your address or fax number, & I'll fax or mail you a copy. orvar26@goldfieldaccess.net
 
I understand that whelen have no STC for the strobe on 14-13-2 . Are yours installed on 337?

Are most of you leaving the original Scott master cylinder in or replacing it with a Cleveland or Matco or something else?

From what I've read, you need to add a reservoir, but you can still use the Scott M/C.
I hope this can be either confirmed or corrected, because it's time to start adding things to the firewall of 392 :D
 
From what I gather there wasn't enough fluid available to fully expand the disc- especially once it started wearing down and needs more fluid for expansion.
Not sure how it is tied into the system though.
Someone jump in here please and set the record absolutely straight?
 
We have also had this problem in the Ercoupe community. It also came with a Scott master cylinder that was speced for an expander type brake system (Goodrich). Those work on high volume but low pressure. The Scott also worked OK with the Goodyear disk brakes but not well with the Cleveland's, The Cleveland's work on high pressure but low volume and the master cylinder is not adequate. The Ercoupe also has an additional reservoir but it does not help with the Cleveland's. They don't need the volume, they need pressure. We have available to us from one of our parts suppliers an STC'd Matco that does the trick.

It is Skyport Services http://www.skyportservices.net/ I just emailed him and asked him if he would be interested in expanding his STC. He is and is asking what the original brakes are on the Cruisair. Do you know? He said the master on the Ercoupe is a Scott 4350. My Bellanca parts book calls out a Scott 4000. Anyone know what the difference is? The Ercoupe master has a built in reservoir and looks like the one in the Bellanca but the Ercoupe did have an external reservoir also, I think because the master is impossible to service without removing the floor. The Matco comes in both versions. In the Ercoupe the STC uses one without the reservoir.

Hi all,

I replaced my Hayes wheels and brakes with a 337 in 1985. Bare bones cost on parts. Used 1-1/2 inch Varga axles, Mooney 20A Cleveland 600x6 wheels and brake assemblies, and Cessna master cylinders with 1/2 inch dia. piston for the correct mechanical advantage. Also changed out all 'O' rings to ethylene proplene to be compatable with the original vegetable brake fluid.

Quite easy and to change over. I have my 337 if anyone wants it. It has all the details and Part numbers

My parts catalog calls out a Scott 4000 master and Goodrich brakes but the TC says there could be Goodyear, Goodrich or Firestone brakes. The TC does not specify a master cylinder. Now the Handbook of Instructions which is the only thing that resembles a maintenance manual says brakes are Goodyear or Hayes. It does have an interesting sentence in it that says you can’t use the same cylinder for both. I wonder if this gives us the leeway to use whatever cylinder is appropriate for whatever brake system is installed and approved on the wheel? I am tempted to installed the Cleveland masters and write it up as installing a part that is appropriate for the job and removing one that is not. Any thoughts on this?



Thanks,
Kevin
