Hi Guys,

I'm wondering if any of you can point me to where I could buy one of those engine replacement jigs. I've seen one for sale at the CNW site, tho I'd prefer it if I could source one from the UK.

Either that or point me to a drawing of how to make one?

I need to get one in there for when I take the frame down to get it straightened.

Ta muchly :wink:

Would anybody have the dimensions or a print so that I could make one myself?

Should be easy. Just measure from the front two cradle bolts to the front Isolastic bolt. The tool is just a link between these three holes.

Thanks RonL, Motor is already out and the Dunstall is in storage, anybody have time to draw something up from their bike?
 
Mine is out for cam replacement so here is my crude support........hole dimensions from cradle to front Iso bolt are 9.62 top and 8.4 bottom. 6.5 rear cradle centres. All approximate but close enough for a piece of 3/4" chipboard!!

Thanks Keith1069 :wink: Close is perfect, the bike can be a roller while the engine is being worked.

Using a plate is ok for moving the bike around but you might need something more precise if you're sending the frame off for straightening. If they are using any kind of measuring setup like a frame table you can get quite a lot sorted out with an empty case, barrel, and head with headsteady in the cradle. In fact, its the only way. They'll need the all the mounting hardware, iso's, swingarm, and a stripped rear wheel if you want to go all the way. There are so many ways things can go wrong between the frame and the rear wheel on a Commando. As the old sayings goes, "Many is the slip between the cup and the lip." There are a number of people here in the states that have the equipment and know Commandos, but I'd think you should have plenty to choose from in the UK. This is an interesting bit of reading.
