Engine Mount Collar/Sleeve Removal Tool Question

[Ganboy70]

I shouldn't be afraid to ask but what length bolt should I pick up or order for the engine collar removal? 6"? I have everything else just having a hard time finding the bolt. Also... should the said bolt be threaded all the way through? 

Cheers,

Tom, as I remember I used 3/8'' all thread to remove the collars on my 91. You might be able to find it at Lowes or home depot..

Thanks Eric, it's hard to find an all-thread around where I live for some @#$% reason...

3/8 all-thread is very common.  Any decent hardware store, not just HD or Lowes should be able to provide you with it.

Didn't we have a write up on this (w/pictures) somewhere?   I can't find it. It needs to go into the File section....Pat

Very good, I'll be sure to credit Bob...I looked all thru the yahoo file section. I didn't think to look in the photos....

Thanks Randy.

Thanks guys, I did read the files before, just wanted to get the right tools for the job.  I ended up using a a stainless 6" lag-bolt with a nut on the end, it moved slightly but I broke 2 of them due to the seizing, unbelievable how bad they were on.  I then hammered them out with a 6" 1/2 extension and correct socket, thanks to Arnie's recommendation in an earlier feed.

I should probably comment that when you do decide to go all cave-man on the mount pivots you use some caution.  You do NOT want to break the mounts off the case.  It also helps to soak them in acetone/ATF mix for a day or so first.

I did soak them well Arnie, just like you said. It's tempting to smash the shit out of them but yes HOLD back no matter how frustrated you are...

[Pat Conlon]

The culprit not to be named, but yes, I've seen with my own peepers how the mount can be broken off the engine case by going Nethandral on it....

A smart man learns from his mistakes...but... a Wise man learns from the mistakes of others. Thank you teacher!

BTW, the collar removal info. is now in our Files section under General Maintence.   Cheers!

I used a half thread bolt and removed it a couple of times to pack it out with sockets, nuts, washers, anything that would fit over the bolt and keep it in the thread range. After much discussion about thread pitch I used a course thread high tensile bolt and double depth nut. That was my final puller after two previous failures. I could have removed the motor without unbolting it with that one. The nut was easily come by, the full thread bolts aren't. However you do it, don't give up. If my experience is anything to go by, I used to grit my teeth and steel myself for the painful noise (vibes) that 4000rpm up brought on. It is now turbine smooth in that range and rough below it - probably always was but never noticed.

This bike is a work in progress, unfortunately I can't compare notes as I haven't yet ridden it.  Lot's of neglect, but could be worse as the PO's did keep the fluids maintained and used high quality replacements.  She's a keeper...
