My 1450 Adventure

Gillis PM me with a price on the tail lights I'm in need of two.

Well gang, I have taken a few pictures of where I'm at so far. I have since split the tractor, lifted that heavy transmission away, and put the engine on a stool. I got the transmission taken apart, and right now I'm cleaning things up. There are many points to inspect in the BRSM. However, I'm not planing to take the pinion and ring gear out.

On a side note, I came up with a few parts that I'm going to rattle can-paint on my 1450 starting with the transmission once all of it is inspected and put back together.

I'm waiting to see what you find as a source of the rear end noise......

Thanks for the update, John!

Here's the skinny on what to have expected as standard equipment on a model 1450 in 1975:

dry type air cleaner
ammeter
implement lift lever with set stop
hydraulic lift
disc brakes-two wheel
drawbar-non-adjustable
electric starter with key switch
fenders and foot rests
fuel gauge
front electric PTO clutch
maintenance minder
quiet features
hydrostatic transmission
heavy duty muffler
seat being spring mounted and upholstered with foam rubber
two headlamps, and two tail lights
Kohler air-cooled isolation mounted K321AQS engine

Tires-Standard and Optional


6.50-8 front, and 8.50-12 rear, OR 6.50-8 front with 10.50-12 rear
~ also there was a choice of AG Tread with bar tires ~ the same size listing available as noted above.

This is me, the author and OCC member since 2009, of this 1450 adventure thread. I'm trying to locate and find a mysterious noise from somewhere in the drive line or transmission. Pictures maybe many, as they may point out to the more experienced members on part conditions. By the way, that transmission behind me was a heavy cast! After this build, there will be no more heavy lifting for me!



This is a picture of my IH cub Cadet Quiet line model 1450:



The serial No. is 2050066U545403* . I believe I have a March, 1975 build date. The tractor came with a decent 50" mower deck. The machine currently is sporting an IH 38" mower deck borrowed from my model 86 IH Cub Cadet.

Kind Code: 205

Machine Code: 0065 or 0660

Now the 1450 is starting to loose some weight:



Speaking of weight, the model 1450 has an approx. weight of 690# with out operator!

When I removed the firewall, I noticed a repair that I will be attending to:



It's the fuel tank strap support. I have a replacement on a spare part to use.

Here is the Kohler engine on a stand. I plan on cleaning it up some, and removing the engine cradle for a oil pan inspection.



** Engine oil capacity: 3 pints

A little about the AQS engine: This tractor series began with an engine that had many upgrades. A few of them were a larger flywheel with increased fin spacing that produced greater cooling capacity. A new Bendix starter provided much more quicker starts in the coldest of winter, and in the summer heat as well. These starters would spin up a good 400rpm! Then the next major improvement would be a alternator installed behind the flywheel resulting in zero battery drain while operating-even at low idle!

Can you describe the "noise"? The hydro is going to whine some when in operation, but I'm guessing you're used to that from your other Cubs. Fresh oil and filter helps with that.

The best I can describe the noise would be similar to what is heard when someone would crack their knuckles- I know, weird. However, the tractor noise would be noticed at any speed range, when turning left or right, and happened quite often to warrant a tear down. I got to tell, that the tractor and transmission operated perfectly well, and no unusual heat was noticed. Aside from the suction tube fluid leak, there was no major concerns other than this persisting noise. Another description of the noise may resemble to the reader would be as if any of the many bearings inside the transmission were binding, or had a flat spot, or other?

I'd wished I could have made a video of the tractor in operation in hopes of hearing the sound captured. I'll be updating much more tomorrow.

Well, here is a quick shot of the unit before I tore into it. As I study it now, I can see it in a golden coat of shining, yellow paint!



Not the original way to remove the fluid, I was able to retrieve about 90% of the fluid out, making rear cover removal much more of a cleaner job. With the top cover removed, a peek inside tells a story. Clean fluid, and what looks like white wax stuck to the inside perimeter of the casting. This would be encapsulated moisture. By having a quality fluid such as Hy-Tran, removal of moisture is assured! Common to the hydrostatic drive models is a certain amount of heat that develops, thus cooling down after use results in moisture, respectably.

** Transmission fluid Capacity: 14 pints



Here, in the picture below, I now removed the hydro pump from the cast iron portion. I was happy to discover how well my previous cork gasket replacement actually sealed up. You might not know it by the picture, but there was not one drop of fluid leaked here. It was stuck well!



Axel carriers now removed too.

Next, looking through the bearing cage, I try to inspect the made in U.S.A carrier bearings. With my finger, I can rotate them. I do not feel any resistance, flat spots, or any grinding noise at all. No cracks, nicks, obsessive wear, could be found anywhere here, inside the side gears. The same discovery would hold true to the opposite side of inspection. When the time comes to button this unit up, I want to be quite assured it's in sound mechanical condition. So, the story follows with the next group of pictures:



Carrier bearing part #: WP14138A U.S.A , #50792R1

Some more,....







I looked at these bearings located at the end of the carrier housing pretty hard as well. They seem to check out good!



Here is a short video. Everything seems to be in order here!

I'm planning for some more shop time later today. We got dumped on with around 3" of the white crap. and to top it all off, the sister in-law is coming for a visit....all the more time for me to be in the shop!
