2014 GU catastrophic engine failure

Post by RobH » Mon Apr 02, 2018 1:27 pm

Good Morning All,

I had an adventure ystrdy.... was riding home on the island hwy, minding my own business at 90 KPH when without any warning at all the engine made a sound like a bucket of rocks being rolled down a cliff and then seized solid. This was in heavy four lane traffic on the Easter weekend. Luckily, I was in the far right lane and was able to pull the clutch in and dive off the road before I turned into someone's hood ornament.

I sat there with my thumb out for 3/4 of an hour (it was snowing!) before a car stopped... a young couple with two kids in car seats driving a roached out jeep. Thanks to them I was able to arrange a car carrier and cab to get bike and self the rest of the way home. There are good people out there!

The bike has exactly 15,000 easy Kms on it... and has had its' maintenance done by the book, most recently an oil and rear brake change just last week. No signs of metal bits during recent oil changes. None the less, I suspect that one or both main bearings have failed. I just hope they didn't take the cases with them.

I'll be contacting the Mother Ship on Tuesday as I think I'm either just off warranty or barely in it still. Meantime I'll drop the pan and timing cover and see what falls out.

I'll post some pics once I have something to show.

cheers,

R.

Bummer.

The possible causes are too many to venture a guess. I hope it is a quick fix that you don't have to pay for.

man that sucks big time, i was just starting to feel good with the EFI Urals with many recent members on some extended trips with very few issues. please be sure to let us know what caused this problem. ill keep my fingers crossed that IMWA will work with you if out of warranty. :? :(

My money on a new crank shaft. Bad rod arm/ big end bearing
14 models dont have much main bearings failure. On main front or rear if bearings go bad you normal hear noise days before motor seizing.
Thanks for let me playing guessing game.
Good luck

I'm pretty sure it's bearing failure. Lot's of chips caught in the oil filter and many more in the pan as you can see from the pics. This is a far as I'm going to take it until I talk to the Mother Ship and my dealer. At least it didn't totally grenade and punch holes in the cases.

There are going to be chips everywhere in the motor... so it's a total tear down no matter who ends up doing the work. I have heard that the cranks have been upgraded since my bike was built, hopefully they last a bit longer than 15,000 KMs!

:x :x :x :x :x :x :x

I'm not terribly happy.

Mechanical things sometimes break, that's never going to change. Thousands of EFI Ural owners aren't having an issue today to post about.

We can just hope we won't draw the short straw, and help those who do if we can with knowledge and encouragement.

I wish the OP the best, and hope they can resolve the issue in a quick, painless manner.

If it is aluminum, That shrapnels are more like piston skirt. may be our small rod end let loose.

The shrapnel is steel... I'm thinking bearing race/cage material.

I dunno going by past pictures, bearing cage material tends to be big pieces, in actual bearing cage peice shapes!

Was there any silver stuff in the oil?

Everything I've found so far has been small chips/flakes of steel. The oil had just been changed and didn't seem to have any silver coloured floaties mixed in with it. I guess we'll have to wait until the tear down to know for sure... and maybe not even then as I'm hoping that Ural will be handling things once I get the engine out of the frame.

In the "silver lining" department, this will give me a chance to fix a few rust spots and put some miles on one of the old BMWs.

Just thinking out loud, please do CORRECT me if i m wrong.
If rear main bearing is bad, you are lucky easy fix.
If front main bearing bad, you got to pull crankshaft (dont even try to pull front bearing off while crankshaft still in motor, can be done but not recommended). It is hard to remove crank shaft with seized a bearing, cuase you can not retract 2 rod arms, therefore it is tricky to beat on rod arms with hammer, last option is to cut rod arm with dremmel tool. If you are going that far, replace the crankshaft with the new improved 2nd gen crankshaft
Not telling you what to do, just my opinion, i m a student just trying to learn about ural.
