I am experiencing noticeably low torque with my RTV 500. I am hoping folk can give a little help on what it could be.
A little background on the unit. I bought it with around 625 Hours on it. It was not running at the time and was a project machine. I got it running, did a full fluids and filter change and it has been running ever since. It has been a solid unit and I haven’t had any issues to speak on with it. It has about 890 hours on it now. Here lately, it seems like it is getting less powerful in high range both at takeoff and when trying to drive through “tough material” like loose sand or thick sand.
For example, I took it out a few weeks ago. We have lots of dirt roads in our area and some of them have stretches that have deep sand that is loose – almost like a dry beach sand. I noticed while trying to drive through that material it slows down and it doesn’t really like to push through it. Maybe 10mph. It’s a high RPM and low speed……but it just doesn’t like to push through it. If I keep holding the throttle to the floor it will generate heat and it will want to overheat. So, I let off, baby it through, and keep going. I also noticed if I drive a round for a round 10-15 minutes and stop, when I go to take off again, most times it is slow to accelerate when you start again. There aren’t a lot of issues in obtaining the top end speed, as long as you have 40 yards to accelerate and are on asphalt or concrete.
So – I have already ordered a filter kit for it. I will change all the oils, filters and spark plugs of a 250 hr service. That may solve it. But……if it doesn’t any idea on what I need to do? Do they get that temperamental around service time? I hear people talking adjusting a servo on these units. I don’t want to “tune” the unit outside of factory spec. I would just like better acceleration and torque, and I feel like I had it once upon a time. Just an FYI – when I let off the gas, I get a good 6-10 feet of smooth rolling to a stop. No issues in Low range. Slower speed, but better torque.
