Swapping Robin out with Kohler today

[SpringHollow]

I am not sure how long the shaft is and how much you have to cut off but can you put it on the cutoff side of a horizontal bandsaw and still cut it to the length you need? If you can, that would be the easiest.

I generally look upon events like this as opportunities to expand my tool collection.

Right tool for the right job, I always say!

And the more of them, the better...

You really need a porta-bandsaw, like this:

Cut the shaft today. Surprisingly very easy with hack saw and new blade. I took my time. It took about 20 minutes. Happy with the way it turned out.

Putting the motor in the tub. A couple of problems to solve. In what order does the motor go back in? I dropped it in, hoping that I aligned the front coupler with the front pump's coupler. I think I have it, but can't see to well to know for sure.

2 problems. 1 the rear motor holes are slightly off with the new engine stands holes. UGH!

2. I forgot to put on the spool or shroud cover that goes over the rear pump coupler. And that brings me to, if I had that shroud bolted to the housing over the shaft, there is no way I can fit the motor into the front pump the way I just did it. Is there an order of what gets hooked up first.
It's like one of those impossible puzzles with one right answer.

Slow and steady wins the race. Nice job! So was that shaft keyed all the way down? Looks like there's still a key on the cut-down stub.

Without seeing yours and mine in front of me, I recall the shroud being cut out quit a bit. Don't really remember how its in there....

Here's a picture of my variable volume pump on the front of the engine if its any help.

And of the PTO/Steering pumps on the back of the engine.

It is pretty much the same set up Moss. When I removed the engine I took out the motor mount bolts (4), Slid the engine a couple inches forward. Unbolted the rear spool that goes over the shaft and rear pump coupler. Dropped the rear pump. I then pulled the motor back to disengage from the front pump. I then could lift the engine. I am trying to reverse the process, but something is not right.

The front pump coupler seems much larger than the one that was on the Subaru. The new one is a big lovejoy aluminum one. On my Robin Subaru there was a small shaft on the front of the pump. There isn't a shaft on the front of the pump. The new coupler has 4 allen bolts that bolt to the flywheel assembly. I have a new engine stand that was made for the Kohler. Only difference from the original stand (robin subaru) it appears to be about 1/2" taller.

I wish the back of the tub was like a tailgate on a pick up, so you could open it up and put the motor and pumps in all as one,

A sawzall to open and a welding torch to close....

I spent 4 years in the Navy at Electric Boat while they built our submarine.

The mentality of a group who are really good at welding is interesting. They think nothing of chopping a 3'x3' access hole through 1"+ thick steel submarine hull to run services (power,pneumatics, ventilation). Need to work on a valve in an inconvenient spot? Cut a 10' section of pipe out and that way you can do the work in comfort at a workbench...

I'm just gonna guess that they assemble the whole engine/pump assembly on a bench at PT and then drop it in as a unit. I think that's how I'd remove and install mine if if ever comes to that. I just wonder how they get their itty bitty hands and crooked arms in there to hook up the hoses!
