Well my Evo 3 12.5hp 30 inch cutter belt clutch assy did turn out to be different to the one 2 posts above in the Owners manual for the mk 2a.
There was no way to remove the cutter clutch idler pulley spring with a pick hook from the rear, the spring is fastened into the bracket with a nut on the end.
The forward anchor for the spring could be easily unhooked by removing a split pin, but I didn't. Couldn't see any advantage in messing with the spring at all.
I removed both idler pulleys and got the belt around them and into the guide things, it was quite a struggle with the clutching pulley to get the belt over it as the deck mount brackets run very close to it.
Then removed belt guide from the deck around the main cutter pulley and got the belt over that, then got the belt from the idler pulleys up to the engine pulley, dropped the bracket that runs across under it with the belt guide pins, and managed to push the belt over and into the groove with the handle of a big screw driver.
See pics, couldn't get a pic to show the rear end of that spring, but will try again later.
Next, new main drive idlers go on, then drop the big drive plate assy back in. But after Easter..
