well I guess this is the first of bad news. my brother was running his rd engine today with no problem, then it started shutting off, bad idle etc and seized. we took it apart and found the piston has cracked. Its along the side of the piston. the part that cracked off went everywhere and in the bearing as expected. He will be contacting rd on monday, i suppose they would want to look at it to maybe determine the problem. The engine was running perfectly before this happened. no overheating or anything so we were stumped. im sure he will be post something up about it, but ill try to take pics and post them up later.

This is where our logo Race The Difference comes in. Send the engine directly to me I will take care of it personally no questions asked. I have sent you an Email.

Please leave the engine as intact as possible.

Thank You motorman, ill have the engine sent out tommarrow. Its a very odd failure, the piston skirt cracked off just enough to leave the exhaust port compeltely open at both TDC and BDC... Thanks again for the quick response.

I have to say, I don't think I have ever heard of anyone standing behind their products like that before!

Way to go, Dennis.

BTW, I sent you an email regarding things here in OZ. Don't suppose you've had a chance to read it?

Cheers,

Mike.

I have recieved the engine and analyzed it. At first I thought the rod and piston had been installed backwards as it was backwards as recieved.(however it does not appear to have been run that way. That will definatly break the piston, I do not know if it had been apart and reassembled as the issue would have started immediatly upon starting the engine if that had been the case) The oil hole on the bottom of the rod goes to the crank. But after I stacked it up and looked at it the failure occured because the crank was not fully seated in the engine. The rod and crank pin are totally toast and worn at a severe angle. The angle indicates the rod and piston were in the correct direction. It is always important to install the flywheel and nut loosly and give the flywheel a good rap (on the backside to knock the crank fully forward)with the back of a plastic screw driver handle to insure it is fully seated in the rear bearing. After doing that remove the flywheel and while pulling out on the crank push the collet fully down before installing the flywheel the final time.(because the collet is tapered sonmtimes it will grab the crank before fully pulling it in leaving the crank unseated) Please make this a habit on your engines every time you remove the flywheel or crank.

The crank not being seated could have occured at the factory or during shipping or during end use it is impossible to tell. However it caused the rod to be forced into a significant angle severly wearing the crank pin and top and bottom of the rod. It caused the piston skirt to fracture because it was in a significant angled bind. (in this engine were not talking a little unseated were talking .030 which is alot)

Never the less It will be back on its way to the customer tomorrow. fresh crank, rod, piston, sleeve and rear bearing. NC

Correction to above.
the engine in its entirety will be replaced

There you have it on we go.

The piston/rod being isntalled backwards as you said was after the failure, i had it apart and re-assembled it quickly (and obviously carelessly) so i could ship it out to you. I appreciate the haste in which you solved this problem, and i am glad that there is a person/company in this industry that values its customers and reputation as much as you certainly do. Thank You
