SGT engine install

More on the sage of the bargain 2084. As my earlier thread indicated, this thing had more troubles than I first thought. One coil was not firing, and both spark plug leads looked badly abraded.

So out comes the CH20S engine, and off with the fan shroud and metal covers. Seems rodents have had their way with the wiring - nicks and cuts in various places. The wire to the fuel solenoid was severed.

One of the forum members had a couple of new coils, which came in a few days ago. I fixed the wiring issues. Also found the fuel pump vacuum hose which connects low on the engine was rotted at the engine connection, so all new hoses. The CV joint was dry and one of the balls rusted, fixed all that.

Now I'm ready to go back in with the engine. The book had me remove the 4 CV screws to uncouple the motor. Going back in it appears it would be easier to bolt the CV joint to the flywheel and then stab the CV joint with the driveshaft splines going in, then lower it onto the mounting bolts.
What's the verdict on this?

Indubitably.


an adverb that means “impossible to doubt.” It has a meaning similar to doubtless and undoubtedly, but it represents a much stronger degree of certainty.

Let's try this again without the mounting plate. The answer is yes. Much easier/quicker to stab the driveshaft into the coupling with it mounted to the engine.

I've done it many times and never had a problem. I suspect the factory assembled the tractors that way as well.

I take the engines in/out by removing the bolts from the engine mounting plate.

I'm not sure if this is an answer or not.
The mounting bolts are what they are. You can remove the rear two, but the front two are captured. I'll need to lower the engine over them - unless I can easily remove the plate that has captured them.

I can handle that. the question is whether to start out with the CV joint screwed to the flywheel, or slipped onto the driveshaft and then bolted up once the motor is settled on the mounting pads. My concern with the latter method is the joint getting bumped and coming apart.

Re worded things.

When the engine is mounted on the plate, it's easier to make sure things are square and level when you marry the engine to the driveshaft.

Ah! I suspected that would be the case. Thanks for the affirmation.

Now I need to figure out how to hoist it. I removed the engine by hand with a 6-ft bar bolted to the lifting eyes, and a neighbor on the other end. I’ll need something more controlled if I’m going to align things going in. No horizontal branch anywhere close to my shade tree
