Hello. I bought a John Deere 425 this past spring. The compression was very bad because of the rings. Anyway, I came across your videos and they were so helpful. I hope though I personally don't have a rear end leak. That didn't look like fun at all. But you are so informative and great with the camera. Thank you

Nice job on the rebuild. It will be better than new when you're done.

Great series of videos. I have my 425 apart now replacing the front cover gasket. I'm also going to replace my plastic governor gear while I have it apart. I don't recall you removing the governor gear in your videos. Does it snap off just as it snapped on in this video? I pried on it a little without knowing but didn't want to damage the case or spindle it rides on.

Today I completed the reassembly of my FD620D engine. Many thanks to Junkyard tailgate for this video. I purchased new head bolts.

Hi @The Townhouse Garage, great video. Could you tell me where you purchased your kit for the 445? Thanks in advance

Love your videos. You said you bought the items in a "kit". Was that from JD, or elsewhere? Thanks!

Hello I have an argo conquest 2000 model it looks like. Is the same engine Mine engine is smoking and I was thinking on rebuilding the motor.

Nice quality video Junkyard Tailgate. I'm currently rebuilding mine because of no oil pressure. Everything looks really neat and clean inside. The bit you didn't include in your vid is the oil pressure relief valve. Although my spring is easily within limits, it doesn't reach the retaining plate. This means, as far as I can tell, there is no spring compression at all and so surely the oil would not build any pressure. In my case the spring sits about 1.5mm below the retaining plate. Should I shim it to fill the gap to put the spring under slight compression?

I replaced the reed valve on the back of the motor. It acts like a pcv valve. Mine failed after 1100 hours. It causes oil burn. So while I was at it I put in new valve stem seals and lapped in the valves. I runs great at 1750 hours now on the clock. By the way I had to replace the cam around 950 hours or so.

Where did you source the water pump? I've been trying to find one for a Kawasaki FD 731V in a Hustler Super Z. Do you know if it's the same water pump in the FD 731V? Any help with where to get a pump would be appreciated.

What was the cause of water getting into the oil?

Use left hand drill bit 😊

I am looking at replacing my valve stem seals. I see when you replaced the springs the head was on the block. What keeps the valves from not falling in the engine? The seals? I'm thinking when I change the seals to put air in the cylinder while I work.

Going back together... but a broken bolt can almost ruin your whole day. Gladly it came out easily.

Where did you get the kit ???😊

Camshaft doesn't get enough oiling. What to do? Inside connecting rods v file a small vee, inside 1 2 cylinders this will give enough bleed off to lube the camshaft lobes, and the cam tapets, push lifters will out last the engine. Great design idea but poor shity, parts very cheap and poor! Had mine leaking coolant at 565 hours of use..Looking inside the engine very carefully you'll see many things that take some hand machining especially for proper oiling...FYI

crap chinese bolt. horrible steel quality.
