So,...I chipped wood with the 1445 today for ninety minutes (60%-100% throttle).
- Outside air temp 55-60F, about what it was when I measured above
- engine oil temp 200F
- exhaust temperature 500F, +/-, up from 390F
- outside of muffler now 120F, down from 390F,
- hydraulic oil 105F coming off of the oil cooler and
- hydraulic oil 125F in the tank and oil filter.
Muffler wrap for the win!
As hot hydraulic fluids have been a pretty constant issue for me, the muffler wrap was so worth it. I think that the hydraulic oil cooler works better because it now pulls in cooler air over the muffler. I may need to do a slight adjustment of the exhaust tip angle to keep it from blowing on the tire, but no issues so far.
All the best,
Peter
