my kubota rebuild

[mattbatson]

install went pretty well...

all torqued on at 8ft lbs on the little 10mm bolts.

spread some motor oil on the inside of the oil seal to help it slide onto the crankshaft.

I went to install the flex plate and after cleaning the area some more noticed the freeze plug here is a little rusty.

another pic

this freeze plug is normally covered by the flexplate, meaning if it ever started leaking I would be separating the tractor again

do you guys think it is bad enough that I should do it now?
or not bad enough to worry about?

I hate to stall out when I'm getting some momentum, but want to do things now rather than later IF needed.
thx

That's just a little surface rust on a bare (no paint) steel freeze plug. No need to replace it.

I don't recall ever hearing about someone having a freeze plug leak on one of these. I wouldn't bother and would worry more that a replacement may leak. How would you test it while taken apart?

sounds good, on to the flywheel then ! :thumbsup:

I do have another little problem also...
In my factory kubota service manual it speaks of a metal shim or gasket, in the shape of a circle, that the 5 flywheel bolts go through when bolting on the flywheel.
It had been a month or so since I had pulled the flywheel, and I didnt remember removing such a thing.
I know for a fact that this shim/gasket didnt go on the outside of the flywheel, as I had pictures from pulling it off.
so that would mean that it would have to be on the inside, between the crank and the flywheel.
So, after searching the garage and coming up empty, I went to the dealer to order it up.
The dealer couldnt find it anywhere in the schematics on the computer. I looked over his shoulder and sure enough there isnt anything there on the parts breakdown?

Does anyone have any first hand knowledge about this ?

Should I just bolt the flywheel up and call it a day?

I'll take a picture of the service manual instructions and post them up...in about an hour or two
thx

okay, so the flex plate is on...

and then the flywheel went on without a hitch...blue loctite on the bolts

but then I checked the manual to see if I missed anything AFTER I installed everything :drunkie:

as you can see they mention some sort of flywheel washer, and it would seem to indicate it is steel.

but again, went to the dealer, and they showed nothing of the sort on their schematic's.

Very nice and informaitive rebuild/restoration going on. Keep up the pics as they are great..

From the Pic of the fly wheel there has been a washer and this is commom on desiel.

From the damage to the flywheel it may be damaged previously.

this is what i found when I split the tractor.
there isnt a washer there?
Do you mean on the INSIDE of the flywheel? Between the flywheel and crank?

Question Who is saying the tractor has not been apart previously?

The shim washer goes under the bolt heads and against the fly wheel.

On viewing that there may not have been one and your manual may be for a earlier or latter engine.

Leaving it out is not likely to cause any ongoing problems or you may have to look at a wrecker to get one.

From that Picture the bolts don't seam loose but the engine was run for some time after the clutch had flown apart.
