Lk3054 tractor splitting questions

[Johnwayne07]

I have a 1996 lk3054 and the clutch was slipping and had a rear main seal leak. so I split the tractor and found that clutch was toast and when i pulled the rear main seal out two pieces of metal fell out. after researching I found that they are thrust washers, I never had any knocking noise or anything before splitting the tractor now my question is can I pull the oil pan and #3 main cap and install new ones or am I in for tearing the engine down?

Also does anyone know what proper thrust is?

In the LK30, the Flywheel end main bearing case carries the 4 thrust bearing halves. The two halves on the bottom have tabs on them, the two halves on the top do not. It would appear that you have the two halves from the top, but it is difficult to say, they may have been sheared off. If you have the time, could you post a picture looking at the back of your engine as you have it now? I am not sure if you can split the rear bearing case into its two pieces without doing a lot more disassembly.

Right now my thrust is .125 witch seams insane to me

 

[xcgreene]

So thats where you found the two pieces? they fell out just after you removed the bearing case cover which holds the lip seal?

.125 very well may be the thickness of the trust bearing that has fallen out.

Could I bother you to take one more photo looking at the area I'm pointing the arrow in the picture? as best you can, I know that angle wont be very easy with a camera.

 

[Johnwayne07]

Yea I pulled the seal cover off and both pieces dropped right out from behind it

 

[Johnwayne07]

From what I gather it's part number 24

 

[xcgreene]

Some diesels you can see part of the thrust bearing halves without disassembly, Shot it the dark I suppose, I was curious if this was the case. Is it possible the pieces are from the cover you removed? one can hope.

have a look at this. It is your crankshaft and bearings. What manual are you using to assist you if any?

 

[Johnwayne07]

No manual couldn't find one for the tractor and I think you are right id bet money that's where they came from since they were right at the seal cover

Should be a 24 & 25 ? Has one of your pieces had a 'tab' like #25 torn/worn away?

If 2 x 24's were installed on the flywheel side of the bearing retainer they wouldn't have a 'tab' to stop rotation where-by they could spin and wear away?? There's an oil groove on the inner face only it looks to me.

0.125" is 1/8" so you could conceivably have 2 x 1/16" thrust washers (one on each side as per JW07's diagram).
Measure your thrust washer pieces (thickness). Are they anywhere near 1/16" (0.0625") ?

Edit: I'm referring to Post #7 diagram.
