Thanks. Trust me it'll work. I know I'm going to find at least one more big obstacle, but I can't see anything big that'll stop it from working.
As far as speed, it's actually only going to get a small bump in top speed. The lowest low is going to be way low. I thought about celebrating completion (soon I hope) by putting it in low-low idling and tying off steering in a tight circle. Put it in a field and grab a six-pack and see how long it takes for it to look like it's going to hit something.

Your doing a great job , should be pretty handy having different gears when you need them . Did the Crosly trans use some kind of sealed output bearing or did it use a tube driveshaft like the PK's ? Al

You know, I don't know what was behind a crosley transmission. The PK's had the drive shaft tube and the speedex's that used this transmission just had a sprocket. That's what this one is getting - it's getting a sprocket right on the output shaft, and that is going to be placed right where the Panzer sprocket is today. I got a new length of chain because I know that it'll need at a few more links. Plus my old chain was 2 different ones spliced together, time for a new one.

This really has my interest now. The one thing that kind of sucks on the Panzer design is the fact you need to shut down the engine, and manually move the belt to another pulley groove to change drive speeds. Not to mention my mid-mount PTO is going to run off the smallest pulley on the engine so I will be limited to med/fast drive speeds.

If you don't mind me asking.. how much did you score your transmission for?

So if the transmission had reverse one could essentially remove the cast pulley and rubber reverse wheel setup...

Yes on all counts. Your head is exactly where mine was when I started this. When I get done, I am planning on using my "low" to run a PTO Belt as well.

I got the tranny for a hundred. That was a lot more than I'd originally hoped for. But if you watch the power king trannys on e-bay and craigslist, a rebuilt one goes for about $250. The parts to do a rebuild are about $60, mostly in the main bearings. So, I'll be in it for $160 when it's done.

I could remove the rubber wheel and pulley, but I need the PTO out on the end anyway so it'll stay. Also, I'm going to be mowing in low gear, so hitting the reverse rubber when I'm in low will give me a nice slow reverse using the stock panzer reverse.

Very cool. Didn't think of driving the PTO off the drive side pulley... but i guess if you don't need the pto running while the tractor is not moving that would work. What style PTO? Kinda like my 2000rpm mid-mount or the slower 540rpm?

Thanks. Not really got an official pto in mind, Mr. Bow. I was just thinking about running a generator heador even a panzer right-angle gearbox over on the drivers side. If I did that, then I may think about finding a snowblower for a t70.

Parts came in today. If it's slow I should get some solid time tomorrow and Wed morning to work on it. Just a teaser for now. Stay tuned. Same Bat-Day, same Bat-Channel.

We had some questions going on with Mr. B Down about gear ratios, so I thought I'd just post what I have in my build thread

STOCK PANZER:
Pulley #1 2.75:1
Pulley #2 2.00:1
Pulley #3 1.50:1
Chain to Diff: 6:1

PowerKing Tranny
1st & R: 3.294:1
2nd: 1.721:1
3rd: 1.000:1

I changed the drive sprocket from 8 to 12 tooth so my:
Chain to Diff is 4:1

You can get overall gear reductions by multiplying them. For example:

1st pulley on a stock panzer has a total gear reduction to the rear axle of 2.75 x 6 or 16.5:1
3rd pulley on a stock panzer has a total gear reduction to the rear axle of 1.5 x 6 or 9:1

New drive train and the belt on the 3rd pulley and the tranny in first gear: 1.5 x 3.294 x 4 or 19.764:1
New drive train and the belt on the 3rd pulley and the tranny in third gear: 1.5 x 1 x 4 or 6:1

So you see, I should be able to run on the panzers 3rd pulley about all the time. There it will have a first gear which is lower than stock first. And 3rd gear will be higher than stock 3rd. I should really only need the 2nd pulley when I need more gear variation or if I need a very low stump pulling gear.

At least this is what I hope. Fingers crossed.

Okay, today made decent progress. Got the tranny re-built and fitted the shafts to their ends. Got as far as doing a rough fitting. Have to modify the front mount some before it can be lowered down completely into place. Also put a picture of the hub which connects the transmission to the 3/4 inch shaft.

Dean, glad the dry fit was a success. Thanks for the detailed follow ups, this will really help the next guy.

Thanks for the encouragement guys.
Meant to keep the ball rolling this morning but decided to sleep in instead. Now it's 90 outside and there's other things I'd like to do for the 4th.
