I bought a non-working Husqvarna riding mower with a 22hp V-Twin engine (407777 1195 B1) for cheap. After opening the engine I found that the engine was destroyed; bent Camshaft, one connecting rod completely broken off one of the pistons, the cylinder for the same side that had the broken connecting rod had a 1-1/2" hole broken off the cylinder wall. (See attached photos) I am a novice small engine mechanic but have always been able to fix pretty much everything I put my mind to. I've done a lot of auto mechanics over my 64 years. I feel confident I can do the work. My question is about whether it is worth it to rebuild an engine using any undamaged parts I can and buying a used engine cylinder block and sump off EBAY or Facebook Mkt Place.

When buying a used engine cylinder block to replace my damaged 407777 1195 B1, do I have to buy exactly the same Model Number AND Type or does it just have to be a 407777?

How do I check the that the Crankshaft is not damaged? (Other than obvious visible damage)

Any advise you can give me is much appreciated!!

I would say since the block is damaged that it is not WORTH because parts will cost you the same as a used engine. I would junk the engine but keep the good parts especially the carb.

Most Briggs twins are plug and play. Can you upload a pic of the engine shroud?

Why is there zero visible oil in these pictures? Wow...... Did you clean it out with solvent? Look at that cam.

Agree most of it is damaged. Look for another cheap rider and rob the engine off it. Facetrash market is one place to start.

Here is the info on the shroud...

I drained all the oil before opening up.

I uploaded the shroud, was that what you were wanting to see?

Basically you are looking a replacement engine with the following specs so all the PTO end parts fits.

Yeah, the fact that it's an "Intek" series engine explains everything. Avoid getting an intek replacement engine.

Based on the engine Specs above, 22hp, etc., what do you recommend I get that will fit on my Husqvarna rider?

I read I also need to match (or better) the amperage O/P of the alternator too, correct?

You should get a 44 series Briggs. Very common but very good. Your engine has a 40xxxx model, so its a 40 series. You want a 44 series with a 44xxxx model number. Make sure the shaft size is the same.

Would this be a good replacement engine? How's the price?

That would be perfect but you have to measure your pto shaft. What's your Husqvarna model? Deck size? If you want to buy a $700 engine, go ahead, but I would assess your riding mower's value. Is it worth putting an expensive engine in?

I would get a parts mower with a 44 engine
