Lower front motor mount

Postby FlashBack » Mon Nov 25, 2013 10:43 am



I have a question. I was changing out my starter. I had to remove the engine cage and floorboard on the left side. The nut was pretty frozen on it. The lower bolt that these are mounted to i think, may have broke.
Is this one long bolt that runs through the motor and allows the cage to be bolted to or am I okay?
If it is broken, what are my options? New to GoldWings and this is the first real work i have done on the bike.
Thank you

To my remembering,it goes all the way through...And there may be a nut on each side..If it's broken..replace it.I really can't believe it's broken tho...Galled/stripped the threads perhaps but I doubt that thing broke in half.
I don't remember if I still have one but somebody should..
This parts list may help...b

It goes all the way through and often gets replaces with all thread if any more than one accessory is or was bolted there. All thread in many instances will corrode and can be a real pain to remove. I hope this isn't what you have but since you said it broke off my suspicion is that you do.

So is there a tube it passes through inside the engine or is it exposed?

Not inside the engine.Its a external casting bore.there's no oil there.
As I recall the front one is a solid bore hole.The rear is partially exposed.

So its possible the threads are just stripped the? If i push on it, it seems to in the direction i am pushing into the engine pan I assume. If i pull on it, it stops licke there is a backing on it

Could you elaborate more on "external casting bore". That would be extremely helpful in trying to determine what i am dealing with.
Thank you

External casting bore means a hole that goes through the engine block, but is not connected to the "guts" of the engine - so no oil can leak out of it, because it's not connected to anwhere that has oil.

If you are trying to get the bolt out to inspect jack the engine up a bit. If still stuck put the nut back on the end of the bolt and hit it.to break it loose. If still tight find a rod/dowel a little smaller and use it the drive the bolt out..

So is the External casting bore threaded all the way through or am i able to just pull the through bolt out after putting a jack under the motor. The through bolt is definetly broken. I just pulled on the cage on the right side and the bolt slid out a bit. The left side cage is what i was removing and that side is what i believe broke
Thanks again

The casting is not threaded...it's just a hole... The "bolt" may just be jammed/seized in the hole with rust...
Grab the end with vice grips...turn,pull,push,wiggle,tap...it will come out...Soak it with penitrating oil...whatever it takes to extract the broken half....either end....
Once out...clean the bore and put in a new bolt..

Well after reading your post, i went down to CyclePsycho Salvage http://cyclepsycho.com/ and he had a drawer full of coated all-thread for the through bolt as i have accessories and the stock one won't work as it's not long enough. No charge.
Went home, got my floor jack out, took pressure of the bolt and replaced with the new all-thread with ease.
I'm really glad it was as simple as that.
Now to get the bike back together after my starter rebuild in time for a toy run on Saturday.
High is going to be 48 in Eugene, Oregon. Ride is at 10:30am. So temp will be around 40-42 at that time.
It will be time to winterize and put away after that. Just one last ride! :D
Thank you for all the helpful knowledge.
Happy Holidays
