We have an older Case backhoe at our shop that definitely sees its fair share of use out on job sites. In fact, I was operating this machine a few weeks ago when I noticed the HVAC system was performing rather poorly.
Our BH-2 Super L is one of our most often used job site workhorses.
I really noticed how bad it was once the weather started to get cold here in Pennsylvania. I was digging out a trench and had the controls set to high temp and high blower speed. Everything seemed fine while I was operating the machine and actually doing the dig. But when I would stop for a few minutes, the cabin seemed to get cold right away.
The door seal on this backhoe is crushed and deteriorated.
At first it seemed like the heater was just not putting out enough heat, but even at idle the fan was blowing strong and the air was hot. But while I was looking around the cabin, I noticed something at the bottom of the door.
Special adhesive sealant is required for proper installation.
