Ok.  I bit the bullet and bought some replacement engine mounts from a e-pay site.  (they shipped to Canada using USPS and I didn't get dinged for taxes or import duties).  http://www.ebay.com/...sd=110816730864

 

My son and I pulled the motor.  Wow - we are way into it now.

I'm not able to get the brackets off the motor.  The bolts that hold the mounting brackets to the bottom of the motor are threatening to not move.  I'm afraid that I will strip the hex head bolts or break the allen key (bolts sourced from Ikea?).

 

Question - how hard should it be to turn these bolts?

 

Question - if you turn the pump input shaft by hand should be smooth or have a vibration/pulse?

 

 

I believe the lovejoy coupler is in great condition.  Edges appear square and the rubber feels pliable.

There was some oil in the pump housing and on the back of the motor.  No idea if it came from the back of the engine or the front of the pump.  Either way, I can't feel any end-play or side-to-side play in either shaft.  I'm not going to dig any deeper.  I'll just keep an eye on it.

When I tore my 224 down I could not get mine loose just left them on the oil pan. The pump is gear pump the  pulse is the teeth mashing together with oil or oil film on them.

I may be able to borrow an air rivet gun so I won't have to take the plates to a shop to have the rivets installed.

Probably better to leave the mounting plates on the motor.  One less thing for me to put together wrong.

 

The way the pump feels - that makes sense.  Now that you mention it, it feels like straight-cut gears.

This stuff should come apart but it's likely to be a bit of a struggle, I usually rattle things apart with air impact as it tends to save on knuckle damage. As far as the pump goes be sure it's not leaking and if you have questions just replace it as they are easy to find and not a lot of cash. I recently dropped an 18hp Kohler V-Twin in a 646 and had to do a redesign on everything but the tractor now works very well. Sounds to me like a great father son project and I wish you good luck. Here are a couple pics of my little project.

I used my impact on those Allen screws and it did the trick. I was in the same boat with the threat of stripping. Get a good brand name bit and hit it with the impact. As for the rivets, I used a manual rivet gun and got the job done with some steel rivets. Can't remember the size but I got them at the hardware. Good luck!
