Many of these after-market parts will also fit the Ford 8N.Īgain, as long as the turnbuckle and plunger are from the same source and a matched set, they will work. After-market parts are available and the same parts are used on the Ford Ferguson 9N, 2N, TE/TEA-20 and TO-30. You will then have to purchase a new turnbuckle and plunger.ĭifferent threads have been used on the turnbuckle and plunger assemblies over the years so be sure you purchase a matched assembly from the same source. You may not be able to unscrew the threads and if not your only option is to cut the plunger with a hacksaw. With the assembly removed you should also be able to carefully apply heat to break the threads free. Be patient, you should be prepared to apply penetrating oil for several days. With the control spring assembly removed you can begin applying penetrating oil and hopefully be able to unscrew the turnbuckle from the plunger. Once the top cover is removed you will be able to remove the clevis pin that attaches the plunger to the upper fork, remove the three bolts securing the lift spring seat support, support plate, plunger, and control spring assembly. The best solution is to remove the top cover after disconnecting the top link rocker,and the control valve at the bottom of the lower fork assembly. Disconnecting and removing the top link rocker and applying force to the turnbuckle is likely to bend or break the upper and lower forks and likely the control valve. That means the threads on your turnbuckle and plunger are likely frozen with rust.Īs rugged as the top link rocker and control spring appear, the components at the other end of the threaded control plunger are fragile and easily damaged. Most of the Ferguson system tractors today have not had their turnbuckles unscrewed in what could be up to more than 75 years.
Sadly, this simple maintenance procedure was, and is often ignored. Today anti-seize compound is far superior to grease.

The operator’s manual directs owners to disconnect the top link rocker, unscrew the turnbuckle, and grease the threads every six months.
