Title: R.I.P. Ural
Post by: Connito on July 22, 2013, 09:39:36 AM
A couple of weeks ago I noticed that one of the carbs was leaking. I removed it and found that the float level was too high. I removed the spark plug and kicked the engine to get the gas out of the cylinder had and thus preventing a hydrolock! For good measure, I changed the oil and the oil filter, although there weren’t any visible signs of contamination. I cleaned the carb and set the float level, making sure that the needle was in good shape and actually closing the flow. I then installed it, adjusted the air mixture on both carbs, the idle and throttle and synced them. I put on new spark plugs and the engine was sounding really well. I took it out for a spin around the block, and I must say that it ran better than ever. Really good! For an Ural anyway. I was very excited, so I wanted to take Silva and go for a ride. However, when she came back from the errands she was running, she said that she would have to prepare dinner and I need to water the yard. Oh well, I said, and then turned on the hose and starting watering the plants. An hour later (yes, it takes that long to water the plants) it was apparent that we are not going to go for a ride as it was getting dark already. I went to start the Ural to put it back in the shed. I flipped the switch and pressed the start button. Now, most of you know, that I really like to kick start all my bikes (well, the ones that have a kick starter). I am not sure why I decided to use the start button this time. BIG F____NG MISTAKE! Apparently the carb was still leaking, I didn’t turn off the petcock and the engine hydrolocked! I all heard was a big “bam” after I pressed the start button.  I have not assessed the damage just yet, but obviously the push rods are gone, probably the crankshaft and who knows what more. I have a few options now. Sell the rig as it is, part it out, replace the engine with a BMW R75, replace the engine with a newer generation Ural, or fix this one. Time will tell which option I will choose…
Later,
Peter

Oh no! My initial thought is that of all bikes to have this problem, a flat twin is the easiest to at least dismantle. Remove the heads cylinders and see what is what. Hopefully no distortion to the con rods and crank. Question for you, are BMW parts a direct replacement?
Can you use something like an R90 top end to replace yours if need be?


Title: Re: R.I.P. Ural
Post by: Connito on July 22, 2013, 12:52:18 PM
Nope, not a direct replacement. From what I read, the crank is certainly a goner, which means I will have to take the engine off and basically rebuild everything. Not an easy, nor cheap solution.
I am steering away from installing a BMW engine. Way too complicated and EXPENSIVE. I would soon buy a BMW and attach the sidecar to it. I will be loosing my reverse though, which is a must for me. One of the biggest reasons I went with Ural rather than other sidecar options.

If the crank is spun, it probably can be rebuilt. You will not know what is gone until you take it apart though. There is not much to this engine design, and you had practice already with the 175! Now all you need is the Gene of Urals and BMWs to help you. Why not try Phil Rose? If he cannot help, he will know someone who can.

Thanks Andy for the sympathy.

Ben, I think I am leaning towards repair. I have to gather a bit more info. I will deal with it when I return from Bulgaria though. Thank you for your thought and suggestions!

What a beautiful day Sunday was....blue skies, perfect temps and what better way to spend it than cutting up exhaust clamps, removing stuck exhausts and removing engine pieces...while drinking Peters beer :)

Lets start off by climbing all over the bike

(http://i141.photobucket.com/albums/r58/andy750/Sidecar%20-25%20Aug13/Picture001_zps208281b8.jpg) (http://s141.photobucket.com/user/andy750/media/Sidecar%20-25%20Aug13/Picture001_zps208281b8.jpg.html)

A 2x4 is always useful for removing a stuck exhaust - where is that hammer! Treeve gets excited  ;D

(http://i141.photobucket.com/albums/r58/andy750/Sidecar%20-25%20Aug13/Picture008_zps96af7455.jpg) (http://s141.photobucket.com/user/andy750/media/Sidecar%20-25%20Aug13/Picture008_zps96af7455.jpg.html)

Sometimes it takes 2

(http://i141.photobucket.com/albums/r58/andy750/Sidecar%20-25%20Aug13/Picture007_zps6cf0633c.jpg) (http://s141.photobucket.com/user/andy750/media/Sidecar%20-25%20Aug13/Picture007_zps6cf0633c.jpg.html)

Bring out the ramp!! Elevate, elevate...now cut the exhaust collar off since its seized!

(http://i141.photobucket.com/albums/r58/andy750/Sidecar%20-25%20Aug13/Picture012_zpsed87bfe2.jpg) (http://s141.photobucket.com/user/andy750/media/Sidecar%20-25%20Aug13/Picture012_zpsed87bfe2.jpg.html)

Finally the exhaust comes off! Wooo that was exhausting, more beer!  8)

(http://i141.photobucket.com/albums/r58/andy750/Sidecar%20-25%20Aug13/Picture009_zps604a994e.jpg) (http://s141.photobucket.com/user/andy750/media/Sidecar%20-25%20Aug13/Picture009_zps604a994e.jpg.html)

Must have been the high elevation that got it off ;)

A big THANK YOU for all that came to drink beer and have lunch! Oh, and destroying my wonderfully build Russian machine!

I was relying on Andy to take pictures, but he was able to take only a few (most of them of my balding head), since his hands were always busy with beers. So, no more photos. Big mistake! I will have the my camera out the next time!


Fun was had by most (I hope) and the weather was really cooperating!
Unfortunately, I still don't know what is wrong with the engine. The motor is off the frame and the only two left possibilities are cam gear or timing gear. You have to remove the timing gear in order to remove the cam gear, but to remove the timing gear you need to be able to spin the the engine... which is not spinning. I think I will remove the flywheel, which is damaged and it should be replaced anyhow and I hope that would reveal some answers. Otherwise, I would have to drill through the timing gear wheel or the in order to access the second screw and remove it. I see no other options at this point. I will post on the Ural forum later on to see if there is someone who can help.

Thank you all again!

Cheers,
Peter

Hi Peter,

Its the Cam gear that normally should come off first, and normally when the engine will turn, it is a simple deal to remove the gear with attached front bearing and camshaft by simply removing the 2 screws which hold the flanged bearing cover in place. This is not possible with a seized engine, so I think your idea is good, loosen both of the nuts which hold the timing gear( the lower, smaller one)
and the flywheel. Then using a puller, pull the flywheel and see if you can also get the timing gear loose. Removing the visible screw on the cam bearing flange may also be helpful. When the cover underneath the flywheel and clutch is removed,  the back end of the crank should be moveable, so the timing gear will be the only thing keeping the the crank in place. Hopefully, it should be possible to disengage the timing and cam gears at this point, if it has not happened previously.

Post by: Connito on August 26, 2013, 01:29:05 PM
Thanks Ben. I will update when I have some progress. It looks like it will rain on Tuesday and Wednesday, so no riding the CB175, which will give me time to troubleshoot the engine.

Later,
Peter


Title: Re: R.I.P. Ural
Post by: Connito on September 05, 2013, 10:53:00 AM
So I worked a bit on the engine last night. It is indeed the crankshaft that is seized. I will attempt to remove the crankshaft gear with a pulley, but as Ben said, normally the timing gear (or the whole camshaft along with the gear) comes off first and it is very easy to do if you can spin the engine. I will go rent a pulley from Autozone and see what I can do.

To remove the Flywheel, I need a bigger pulley and a 41mm socket. Anyone has one I can borrow?

And finally, does anyone want a sidecar rig? I will sell it cheaply.  :-\

Come now peter, everyone needs at least 1 project to work on.   ;)

I don't have a 41mm or pulley either, sorry.



Title: Re: R.I.P. Ural
Post by: Connito on September 05, 2013, 01:47:21 PM
I've got plenty of projects, thank you very much  ::)

I think I will bring the engine to a machine shop, so they can pull out the flywheel. That is if I decide to fix it, instead of sell it.

Andy, I would have to remove the flywheel in order to take out the crankshaft. I could not replace the flywheel actually. It has one broken tooth and couple of damaged ones, but it would work. However, since I have to remove it anyhow and spend $1,000 (or more) to repair the engine, I might as well replace it.

I am still not sure which way I would go...


Title: Re: R.I.P. Ural
Post by: azure on September 05, 2013, 04:07:50 PM
Hi Peter,

Show the flywheel to the machinist. It may be possible to repair the flywheel you have by welding and cutting a new tooth.


Title: Re: R.I.P. Ural
Post by: Connito on September 05, 2013, 04:31:24 PM
Ben, that might be possible, but the cost would be just about the same as the cost of a new one.

Post by: Vreihenmotor6 on September 09, 2013, 01:37:31 PM

Title: Re: R.I.P. Ural
Post by: Connito on September 09, 2013, 02:16:50 PM
Thanks, John. I think I will fix it. It would just take time as I don't have any spare funds at the moment. I just bought a 41mm socket (Thank you Ben!) to remove the flywheel. Does anyone have a good pulley like this one?
(http://myural.com/Flywheel%20Removal%20007.jpg)

To change the crankshaft, the bearings and the flywheel shouldn't be too difficult. It really is a question of removing the flywheel and allocating funds for the parts. At this point I will separate the sidecar from the motorcycle, so I can store them in the shed and free up space in the shelter for the Cb175 and the CB750, which I will put on the road next week.

Later,
Peter

I'll help how i can, although most of my September is taken up with work trips.

if needed I know a good machinist who is very motorcycle friendly. or if you need a puller tool, or shaft seal install tool I can make one up on the lather or mill, I'd had very good luck making bearing and seal install drivers


Title: Re: R.I.P. Ural
Post by: Connito on September 09, 2013, 03:09:13 PM
Wow! Thank you, John! I think a puller tool and bearing and seal install drivers is what I would need in order to complete the rebuild without bringing it to shop. Let's talk about it.



Title: Re: R.I.P. Ural

Thanks, John! I am far from needing tools for assembly. I am still trying to figure out how to disassemble the crankshaft. At the moment I am trying to remove the rear bearing housing, which is a big pain in the neck!

Here is how the housing looks like when removed:

Which part? Around the world in few hours or perfectly working engine without a crankshaft?

Well, I did take few pictures of me going around the world, but they are all blurry for some reason. Something to the with speed, I suppose.

As for the engine, I am sorry, I didn't take pictures and it's now all put together. However, it is way too fast now since it's too light due to the absence of a crankshaft. I am thinking of taking it apart again and installing a new crankshaft, at which point, I promise, I will take photos. In fact, I might invite you to take part in it, if you behave well.

Okay, so here is what’s going on actually. I have tried to remove the rear crankshaft cover (or bearing housing) couple of times, but I was unsuccessful. I even managed to strip the threads where the pulley attaches to the cover and I had to tap new ones. Anyway, couple of weeks ago John came over to see if we he can come up with a solution as to how to remove that crank cover/bearing housing. After few beers we had a plan for action. He went home and made an aluminum piece which fits at the end of the crankshaft.

The idea was to bang on it to avoid damage to the crankshaft as I was still hopping that something else was a miss. I have attached the block to the table, so it wouldn't move.

John came back last Friday and with the help of the pulley, some heat and a bit of banging - the cover finally came off - the plan worked!

After a few minutes of wondering and with the help of the internet, we were able to remove the crankshaft.

Unfortunately we discovered that the crankshaft is indeed bent and it would have to be replaced. That’s the situation at the moment.

I will have to save my pennies and buy all the necessary parts over the winter and early spring and hopefully have the rig on the road sometime late spring/early summer.

Thank you to all who helped and care!

Cheers,
Peter

aahhh much better. 

So I am assuming that the piston was hydro-locked from the leaking gas and trying to start the bike in that condition ended up warping the crank??

are the rods still usable, or does that whole bit need to be replaced?

It is all one unit. Very weird.

Fascinating stuff and well done for getting to the bottom of it...no pun intended. I look forward to seeing how you will fix it all back together! Good luck!

Looks like the rods are assembled when the crank is pressed together. I am not very familiar with crank assembly, but it does look like one of the rods is tweaked on the shaft. I still think this is a job for Mike R.s friend Zint, who works at Lindskog balancing. Zint has the equipment to disassemble the crank and perhaps help it out.

+1 for Zint - he is the Crank Master

Hmmm! That might be a better idea than buying a new one. Thank you guys! I will be contacting Mike then.

2002 Tourist.

It has a 750cc engine.

Why'd you ask?

Post by: knowsnothing on October 30, 2013, 09:57:05 AM
I was curious as to how expensive the units are to replace.  I found the 650 crank for $230, but i wasn't sure which model you had.  Figures you have the expensive, hard to find version.  :P

I can bring that to Rick Stetson and see if one of the crank pins moved. That sort of thing happens on roller bearing cranks like the old Kawasaki Z's and KZ's as well as Suzuki GS's. The cranks are indexed and the connecting rod pins welded to the counterweight to prevent future shifting

It is!

I am seriously considering NOT replacing the bearings. I was so sure I will, but John mentioned the other day that I might not have to. Well, now I am really thinking about it. It would be hard to replace, plus they are pricey (even the ones I found on ebay) and they do look alright. Plus there is always oil splashing them. Thoughts?

Great! Thanks, Mike! I was just about to email you about it :) I could drop it off Saturday afternoon. Would that be okay?

Part 2- the ressurection( of the Ural, Peter has already risen for his saintly work at my house last eve) begins this weekend.
Stay tuned for progress, but remember, it is after all a Ural.

I leave for a real vacation on Monday so I'll be in prep mode.  It sounds like a good time, though.  I'd like to see the underpinnings of a Ural. I like the more obscure motorbike mechanicals. I had a blast repairing my friends Royal Enfield motor without any manual to speak of.

It's a book of barely discernible pictures and paragraphs of meaningless words that you wrongly feel will give you an inkling of an idea as to how a complex machine might go back together after you took it apart while drinking heavily.
