@dhitching Thanks you for the photos and confirming that there is a variation in plates..

The notched plate has been installed to the extreme left and right then taken out and reversed. Neither options worked.

I will post some follow up pictures of the different PTO lockouts on the two tractors. The Oklahoma tractor originally had the galvanized hinged lock. The donor has a bolted stop to prevent reverse engagement. Both options would for preventing deck moter failure due the abruptly changing direction of rotation.

Pulling the deck, then the motor, new pan gasket is the end goal.

While there is more room to work, the wiring harness will be repaired.

Looks like the oil cooler rad needs to br cleaned. What else will be found?

Clearly some work ahead of you @Spike188 since you're pulling the engine out, are you tempted to do the valves and seats? Check the bore and so on?

I am envious of your set up @Spike188 - not one, but two forklifts in your driveway of course I'm also envious of a solid driveway - I'm debating swapping the casters on my engine hoist for rubber tires so I can use it outside in the BigSky shop

Your future Case loader "engine hoist" has tires already Gerry! Just saying take it from someone very familiar with operating in the BigSky shop.

Thanks @Eugen the thoughts and ideas are constantly swirling around in my brain... sometimes it feels like my head is going to explode I look at my 446 and it's sleeve hitch (I look at it - because I still haven't gotten around to working on it after it got an attitude when I wanted to plow snow with it this winter ) I've got an engine hoist, and a Princess Auto mini truck bed crane that could be used. The mini crane is going to go on a receiver hitch that could mount on the back of Tacoma, or the Samurai, or a Case GT...

Just need to take a break from cleaning and purging house stuff... I understand exactly how some of you feel when it's time to step back and take a breather for a little while

So much for planning to pull the motor and replace the pan gasket in an afternoon. One of the lift ring bolts in the head was twisted off. The standard way of welding a nut to the stub and wrenching the piece out was a bust.

Over a period of 4 hours, sleeping on the problem, and putting off inevitable, the welding method was shelved. The broken bolt did turn about 5 minutes but must have been badly gulled. It just kept twisting off the weld. This is the only time I have ever had to give up on this method.

Even with grinding a bit of the casting away there was no evidence of why the bolt was seizing.

The winning approach was drilling the the broken bolt out. I would normally drill just smaller than the minor thread diameter and pick the remainder of the bolt out of the head. In this case picking was not working so a 1/4 bit was used to clean out the hole. This left enough meat for tapping with an M7 X 1 cutter. 10 pieces of M7 course bolts cost $4.30 and problem solve.

In answer to @Eugen , now that the motor is out the cracked dash panel will get replaced with on supplied by @Doublet . Thank you for the panel Terry, while the motor is out, there is a bit more incentive to replace it t. The control levers have to be removed for dash removal.

7mm bolt vs 5/16

The original bolt was 1/4" or 0.250" the M7 × 1 calls for a drill size of 0.234 (15/64) or 0.016 smaller than the 1/4" drilled hole.

A 5/16 bolt is 0.3125" and calls for a drill size of 0.265 (17/64)

Visually the M7 is considerably smaller than a 5/16. An M7 fit through the tins and hood stop strap without modification. M7's are a rare but stock item locally so with a bit of thread lock the drill size differance of 0.016 is easly delt with. The head of the M7 is very close in appearance to a 1/4" head. To me this is a win, win.

If all else fails an up size to a 5/16 bolt is still possible.
