Engine mount bolt retorque procedure question
« on: March 31, 2018, 10:23:33 pm »
Trying to lessen some engine vibration from my 2014 and have decided to attempt the motor mount bolt retorque procedure. Plastics have been removed, so now I assume you must remove the fuel tank ? So far, can't see a damn thing in there !

Do you have the FSM? Keep in mind that when you loosen some of the bolts they have a factory applied "locktite" coating that should be mechanically removed and the hole cleaned out with a thread chaser or tap and compressed air before applying new locktite and re-torquing. Is it your intention to loosen ALL of the engine mounts or just some of them?
  Can you describe the vibration you're having?

Yes I have the manual. I have the vibrating handle bars problem, it will put my hands to sleep from the vibration, from 3000 rpm up. I have installed weighted bar ends and foam grip covers, helped very little.

I am following a thread I saw here that described supporting the engine with a jack and loosening and then tightening to spec all mount bolts.
Yes, I know I am dealing with loctite and cleaning threads.

I was more concerned about the rear mounts than the locktite. Be sure you understand the procedure before attempting to loosen / tighten them.

Kawasaki thread sealer is not loctite. Use blue loctite if you want the same effect.
If you don't have time to do it right, when do you have time to do it over.                                                                17" wheels, Nissin 4 piston calipers.1kg Sonic Springs.Cartridge Fork Emulators. KB Brace. Galfer brake lines  Free power mod.

I’ve done this several times. My advice to you is go slow, follow the FSM (engine removal) carefully and get Good torque wrenches. The most expensive tool you can own is a cheep torque wrench.
  This isn’t rocket science but it does require patience. The first time I had to do this it took 3 tries before I felt like it was just right and all the vibration was gone. There aren’t any short cuts or tricks just good Best Practices.
  As Pbfoot said the factory thread sealant is not “Locktite”. That’s why I put it in quotes. Locktite is a brand name that has become synonymous with thread sealants. Any brand of “Removeable” will work but the known characteristics of the Locktite brand make worthwhile to use.  Blue is plenty strong for this, Red if you’re truly paranoid and Green only if you NEVER want to remove the bolt/nut.
  I have to believe that since you’re willing to try this you’ve got some mechanical skills so go for it and we’ll do whatever we can to help.

I'm 58 and have been a mechanic /tech for almost 39 years. Tons of tools and a fading patience lol.
  When I got the plastics off, I  just shook my head at how packed the engine area was.  I work on cars, but always maintained my bikes.  I can do this job, but if I keep this bike long enough for a needed valve adjustment, I may have to have a couple beers and think about it .

You're going to be half way to the valves. Why not just do them now?

Once you get the valve cover off there is tons of room.  I'd suggest doing a coolant flush, anyway, and then you may as well remove the radiator, too -- the amount of room you'll have to do the adjustment is almost luxurious.  It was certainly more enjoyable than doing a valve adjustment or spark plugs on the rear bank of a transversely-mounted V6.

I got lucky when I found this bike...bought it last year. The title was in limbo due to precious owner and girlfriend.  It sat for almost a year waiting on a title ..so it really had 1 season on it when I grabbed it. Paid 10k for it last fall.

I'd suggest changing all of the fluids, brake, clutch, coolant and oil.

Oil and brake fluid were done before I put it away, clutch and coolant good idea.

Ok, ready to go . Allow me to describe the procedure for the rear mounts to make sure I have it right. Right side of both rear mounts gets torqued before the left : they are tightened turning left, then  go to other side and tighten the nuts clockwise.  Correct ?

I don't know how many steps you are omitting, but there are a few you leave out here....
Re torquing does require loosening first... then, starting from step one, thru the complete process...
FSM section, 8-9 thru 8-11

And you may want to support the engine from below, with a jack, and a board placed on it....

I have assume you are following directions in a post, moreso than looking at the FSM, which may be difficult...
So pretty much you have to decode the info from that post you quoted...
http://forum.cog-online.org/concours-14-zg1400-general-chat-and-tech/engine-mount-torque/msg238091/#msg238091

Here is the thread, couldn't find the icon to link.


Prior to anyone attempting to clarify wht that original post contained... wild bill hasn't been around for a year, may want to send mim a p/m and ask him about it tho.  That original post spans a time zone of 2 to 5 years since it was posted, and it does contain some useful info for sure, best of luck on the task, hopefully it goes as smooth as it was explained as.

Yes, deepsea mentioned he wanted to be sure I knew the workings of the rear mount bolts.  The thread I posted had a good pic of the tightening sequence. I have the motor jacked and am ready to go. Bench grinder with wire wheel and rethreader dies at the ready.
