Progress, Frame is done and stored. Working on the transaxle. Removing the axle inserts took a little persuasion but they are off.

Still working on the transaxle, everything is going well, although I was wondering why the shifter lever was tight and sticking. I pulled it off and found gobs of rust and crud. Doesn't look like it got through the rubber boot. I am cleaning this up and will add grease to it before I re-install the boot.
The main plan for now is to complete the transaxle, frame, and front axle and order new tires. This should make a rolling frame.
I also bought new mufflers, but need to figure out the mounting, That will come later when I get to the Engine. The transaxle is looking good, but I'll hold off on pictures till I am done with it. Maybe tomorrow.

Wow, good thing you checked to see what was wrong. That looks rusty and it wouldn't have done the tranny any good to have that in there.
Those mufflers will be louder, that s for sure.
Guys, do these Onan's have any tendencies for loosening exhaust seats without the mufflers for cooling buffers? Just want to ask before Larry mounts them on.

Alan, I have those mufflers on the B48 on Big Bertha. They are very noisy. No other issues with them, though. Not sure on the 'big blocks'.

It will be a while before I get to the engine. Mufflers will need replaced, I am open to better options.

I'm not sure myself how these will work. From my own experience with just about any engine especially small engines the muffler designs are overlooked. Exhaust flow, back pressure & of coarse the noise level are all important to consider.

Hi you might check on ebay there are a number of Onan mufflers listed, there are generally some on all the time, most are the single can type that's what's on my SS16 and its fairly quiet lots more than the ST16.

I checked Ebay and mostly the single can type, not sure about (fitment) with these (including with the hood installed).MH81, I don't plan on a "no muffler plan" These are the largest I could find so far (9-16 hp) each that I am pretty sure I can modify to work. The plan is to cut the old can's off and weld NPT threaded pipe fitting to the end of the pipe and try and keep the new muffler within the same general vicinity and angle as the old can. These mufflers are approximately 1/2 the size of the old cans, I'll try another search and see what I can find.

Here is a teaser for the transaxle, I re-lined the brake band today and finished touching up a few other items on the transaxle. Once I install the brake band (after the JB hardens) I'll post the completed unit. The steps to reline the band. 

1. drill out the old lining rivets (the old lining was ok, but only 1/2 as thick as the new)

2. used the old lining to measure and cut the new lining.

3. small dremel to grind off the old adhesive.

4. masking and paint optional

6. pre-fit lining and make sure enough clamps are on hand.

7. mix 1/3 - 1/2 tube of JB.

8. Clamp, and wipe off excess.

As promised, here is the transaxle. I think I'll bring the deck in today so I can see how bad it is. The rest of the chassis is in pretty good shape, but I am a little concerned about the deck.

Thanks everyone! I'll have to admit the Transaxle was pretty easy, This I think will be more of a challenge. I see many broken bolts ahead, and don't expect it to be pretty under the cover. We will know shortly.
