Ride on broken axle/chain tensioner block?

So, I am in Manila area. Got new rubber on my 950 smr yesterday, then tire tech alerted me to cracked/broken axle chain tensioner block (brake side) that the axle threads into. I am not sure how long it will take me to get replacement but think the way the block is "kept" in slot of swing arm, it is impossible for axle to slip past threads. Am I crazy to ride on? tightening the axle using the the axle not on other side (chain side) is secure. takes full torque (90nm).

the crack is at 330 and and 830 roughly. For the two halves to spread (making threads disengage), the halves would have to overcome top and bottom swing arm flanges that contain the adjustment block. If the cracks were at 12 and 6, then the back have of the threaded block could just fall out the back of the swing arm adjustment slot.

Just trying to see if my theory is correct and this is "ridable" until i get new tensioner block?

thanks

added picture with crack shown and yellow stars indicated the swing are flange area that restrict tensioner axle nut movement (keep it from spreading and loosing thread engagement with axle)

Agree Cors. Rode a few hundred km's a couple weekends ago... and everything held together !

I will pick up new adjuster block when i am back in US in December. Appears, however, they only sell adjuster block with axle as complete assembly ! I hate buying extra parts i don't need !
