Took mine off and it pretty corroded.

This bolts onto the block, waterpump mounts to it and the thermostat housing mounts to the top of that.

Im told that it is unique to the stout and not other 3r's.

If you happen to have on e your willing to part with let me know. I am going to attempt to fix mine but old brittle cast aluminum Im guessing doesnt weld well.

thanks in advance.

 

I have one but cost wise I doubt it is viable to send it from Australia to the US, it is off a early 5R and from what I have seen of them there is no difference from the early 5R, 3R in the crown, dyna, coaster, toyoace to the stout. The later model 5R had timing chains rather than the early timing gears, the timing chain version has a separate water pump to the thermostat housing that bolts to the front of the head

 

Think I fixed mine..... Will see if it holds. Instead of welding I used some epoxy which seems to be holding great! If it fails it would totally be worth shipping. NO parts in N. America I can find for this motor!
