OK, I did the parts research. Amazon of course is the place, Genuine Kawasaki parts for less than re-branded JD parts, plus they have a JD 445 cam gear set with almost everything you need. I added new aluminum valve covers, water pump/gasket set, spur gear set, and four push rods, $498 and change. Parts are on the way.

For manuals, forget JD manuals for dollars. Kawasaki offers free downloads. Just gotta search FD 620.

Your engine wonít have a plastic cam gear unless itís an old Ď98 or earlier engine. Find the bar code sticker on the engine.

Mine is a BS01 model. The parts guy can tell you if you have plastic gears.


Mine is only 3 years old with just over 90 hours on it so even if it has some plastic gears I've probably got a while.

I must be lucky . My Kohler on my mower is 13 years old with 690 hours. My onan on my welder has 1800 with no major issues. Iíd be pissed about a major failure at 700 hours.

We've been very luck with the Cub rider, with the Courage 19 AKA the self destructing engine.

Today I clean the heavy piece. Nasty short block. Then I need to leak test the heads using the redneck antifreeze method. Then blow the chassis and radiator clean and it starts going back together.

When I reach this stage in a rebuild, I begin to enjoy myself more. Just seeing everything clean gives me a lift.

The second round of the NBA playoffs is just starting. It's my understanding that they last slight longer than eternity. Think you will get it done before the championship?

Yeah it will be easier going forward. It would go back together if the parts were all here. They will arrive mid week. And, so far the leak test looks good.

Had a heck of a time getting it put together last night. The cover would not fit flush. Tried running it down with the bolts and the crank jammed up.

My stupid alarm finally went off and we just stopped and stared at the cover. We had stripped the new cam out, stripped the new oil pump gear, everything we could remove and the damn cover would not fit.

We both saw it at the same time. The oil pump has a strangely shaped plate under it that was 90į rotated. We fixed that, high fived and put it on. Still would not fit. Stupid alarm is blasting now.

We stared at it some more. This time the wife saw it. My stupid alarm is never wrong.

Do you see the problem -

[Linked Image]

Yep. There it is. I did that. Well it is now on and tourqed down. The crank rotates freely. Then I realized that the head gaskets did not come in the cam gasket set. Donít quite understand that as a cam failure will generally bend a valve stem or two.

So, Saturday we bolt the heads on, bolt up the intake manifold and torque the heads. Then it is pretty much done.

There was never a doubt in my mind it would not live again. Granted, I knew who had their hands on it up
