My 756 lost it's prime on the mcv valve, so I cannot steer and the tractor won't move. I am able to raise and lower the loader, operate the fast hitch and the pto turns. The low side of the ta is out. This only happens when it is very cold.... 5 degrees or less. I am assuming I have ice built up and making my filter into a snow cone! I plan on changing the filter Saturday morning when I have the time. The hytran is a couple years old and still looks very good. I would rather not drain and refill it. I don't use the tractor very often, so, I believe condensation is causing the problem.
I have been searching for solutions on the internet to stop this issue from happening. Some possible solutions include:
1. adding the allied filter extension to use 2 filters...allowing more oil to pass thru. I have the 17 gpm pump installed.
2. replacing a drain plug with a drain plug heater that you plug in. Not sure which one to get or which plug to replace.
3. slapping on 1 or 2 magnetic oil pan heaters...1 by the filter and 1 by the mcv?
I have a torpedo type heater that I can point at the tractor to warm it up enough after I change the filter and hope it picks up prime. If not, I have in the past taken the 5/8 nut off the back of the mcv and started it to prime it. Very messy...hoping not to need this step again.
Sorry for the long post. Hoping to be able to push the snow off of the lane without the hassle of defrosting the system.
