now, I thought about some RTV on the perimeter of the rubber oil seal...the surface that seats within the carrier that it rides in...pics here
here is how I removed the old seal


now here is the new seal as it would go into the case that carries it...


here is the new seal sitting in the carrier...but not pressed in yet...


so, I will definitely put some oil on the inside of the oil seal where it rides on the crank.
and there are two paper gaskets for the carrier where it bolts to the engine, that I may put a thin film of RTV onto.

But , still trying to decide if i should put any RTV or equivalent type silicone onto the outside perimeter of the oil seal :confused2:

sorry if it seems like I'm being overly cautious here, but I really, really, really, dont want that oil seal to immediately start leaking once I get this thing back together again.
I've done main oil seals on cars before and had one or two leak immediately, so now I really take my time and make sure I do it correctly

so I took some of the advice that I got from different people on the forums and used WD-40 to help the oil seal slide in, packed the backside of the seal with grease to keep the spring inside, used a block of wood and very, very carefully banged it in...little by little...to the depth that the original one was in
it all went in straight and true.





used some emery cloth very, very carefully to take off some sharp metal on the edge of the crank where the oil seal slides over...


sharpened a little screwdriver in order to make a scraper that would fit in this tight area to scrape off the old gasket material


this is the inner paper gasket


this is the outer paper gasket


I was going to spread a little RTV onto the paper gaskets and install the oil seal with carrier, but found my old RTV tube had hardened up...so need to go get some in the morning

Once I put that back on, I can install the flex plate, and then the flywheel, then the clutch and pressure plate.

I'll keep ya posted :thThumbsU

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

While it looks like surface rust, for your own piece of mind, I'd change it out. The parts cost is negligible in the big picture of things, but labor to get back to it is pretty extensive.

mattbatson

thx for the advice on the freeze plug...

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.

Any update?

mattbatson

Hey,
I have been so busy. In fact, I'm putting a new clutch into the wife's daily driver as we speak. She has been driving our third vehicle while I do the rear main oil seal, pilot bearing, and I'm doing the transmission output shaft seals while I'm in there.

I do have the flywheel and clutch/pressure plate on the tractor, but otherwise it has stalled out for a few weeks now.

I should be back in it hot and heavy in a week!
