Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello. Thank you for choosing Just Answer. My name is***** will be happy to assist you.
Hal if you are still in need of assistance, please let me know.
I will work with you. If your trunnion shaft will not move, when you move your control arm to forward position, you and I can do some troubleshooting, to help figure out what is causing our problem.
To begin, remove your control arm rod, from the lever on your pump, then try moving the lever by hand. Let's see if you fell the same amount of resistance in forward and reverse positions.
Also, you can remove your return kit from your pump, then use a crescent wrench, to move your trunnion shaft. Rock back and forth between forward and reverse, as you feel for resistance, and listen for the noise that resembles metal hitting metal.
Have you noticed any oil leaks on your pump? This is a process of elimination. You and I can continue from here.
