My experience (and I've had and seen a lot of it) is that the first thing in an accident to go is the front tranny mount. The second is the nose cone of the tranny. Unless there is some prior damage or rust rot the chances of the frame bending in other than a really total wipe out is nil. --- On Wed, 10/15/08, Will Wood <evilscientistboo@xxxxxxxxxxxxx> wrote: From: Will Wood <evilscientistboo@xxxxxxxxxxxxx> Subject: [tcb] Re: Can a collision move the engine?

Things being what they are the frame rails are probably 1/4 to 1/3 less in strength than when the left the factory so any collision could cause an accordion effect. I had a single cab that one day I tried to jack it up on the frame support rail and it crumpled. As they say, they don't get better with age. -----Original Message----- From: sammie smith Sent: Oct 14, 2008 9:26 PM To: tcb@xxxxxxxxxxxxx Subject: [tcb] Re: Can a collision move the engine? There ain't no way the tree caused the pulley problem; or any other engine damage. --- On Tue, 10/14/08, Denis Dodson <coocoo@xxxxxxx> wrote: From: Denis Dodson <coocoo@xxxxxxx> Subject: [tcb] Can a collision move the engine? To: tcb@xxxxxxxxxxxxx Date: Tuesday, October 14, 2008, 5:48 PM I have done absolutely zero work of maintenance on Murray's mechanicals since the tree kissing. When ever I did start him to move him a few yards while doing the body work, there was a banging noise that I thought was the tailpipe banging against the body metal. When Chuck and I were replacing the electronic points with real points, I noticed that the crank pulley nut was loose. It took a few turns. I also had to push the cooling tin away from the pulley. When I started the engine with Chuck looking at the engine we found that the pulley is way wobbly. There was no problem before the crash. I say that I was going, maybe, 15 MPH when I hit the tree, because I can't think that I was going much faster, maybe I was. The question is, would a front collision cause the engine to move forward, maybe 1/4-1/2 inch? How hard would I have to smack to cause the engine to go forward far enough to bend the pulley? Let's all make a wish that the crank wasn't damaged. I'll know tomorrow, maybe.
