1450 driveshaft and seal
 

While showing off my rebuilt 1450 and 50" deck on buddy's new yard/house he just bought, I somehow sucked a piece of bubble wrap into my hydro cooling fan. This wrapped around busted a couple fan blades off, snagged a wire that came from the neutral safety/brake engaged switch and wound tightly around the seal heading into the hydro. That started to squirt fluid real bad forcing me to stop mowing and get to the trailer asap. I pulled the tangled wire and plastic from the seal and she is not looking good. drip drip drip drip 1 per second

What seal do I need and what am I looking at for repair? The driveshaft always had a vibration to it so I want to replace that as well.

Any insight would be appreciated.

You need to pull the Drive Shaft out. Replace any worn drive line parts (couplers, adapters, flec discs, bushings, etc) plus the fan.

Once the drive shaft is out, remove the Hydro Unit input shaft Adapters (pound out the spirol pin). Once removed, pull out the defective input shaft seal. Take that seal to your local Auto Parts store for cross reference, and obtain same. Install new seal.

Once you have all the drive line parts as needed, re-assemble the drive and install back into tractor.

Check you Hydraulic Fluid level and add if necessary.

Wha-La.......you are good to go.

How brutal will that spiral pin be?

Sometimes the spirol pins come out kinda easy , sometimes not !! But they will come out . Spray some PB Blaster on it first , a punch and a BFH. Once you get it to move , they come out kinda easy , most of the time.

You may want to have a spare spirol pin handy just in case you need it.

This is the kind of instructional help that most of us can follow...:ROTF1:
The BFH just hit me funny. Just picturing the swinging, hitting and cussing that goes with such a job... It's only funny after it's finished.

I know we've said it before, but you will find a spiral pin punch set VERY handy to have.

Thanks-- I have the punch set. What are the specs on that pin? I have a set of pins at the shop I could grab one as I am guessing I will trash the current one. Just don't want to grab the whole set as my luck would have it, someone will need it after it sat for the last 5 yearson the shelf.

Per the Parts Manual...........1/4" x 1-3/8"

Please keep in mind that this is a spiral pin, not a regular old split pin.

I almost always grind the end of the pin flush with whatever it is going through before I beat on it, grinding it off helps to keep it from mushrooming out preventing it from going through the hole.
