This 1978 International 1486 tractor serial no. 15393 came to us from a gentleman in Elmsford, NY. We have restored two tractors for him an International 686 and a 1086. We are now restoring an International B414 tractor for him.
Someone had attempted to install a TA elimination kit. A TA elimination kit is installed into tractors to convert them to a gear driven tractor to eliminate costly repairs to the TA.
During installation who ever worked on this tractor failed to install the three plugs needed to stop the oil flow that had previously flowed to the TA. Since these holes were not plugged the oil ripped through the non TA gasket and lost oil pressure. Then we tapped the holes and installed plugs and the correct gasket.
This is the MCV cover. It was inspected and we found nothing to be wrong with it.
Here we are showing the MCV (Multi Control Valve) body with two valves. The valve on the upper left hand side is the bypass valve and the valve on the lower right side is the flow control valve. These two valves had been switched in location and are similar in size but the holes on them are in different locations.
All the valves and new gaskets are installed into the MCV along with the steering pump, and are ready for installation into the tractor.
This is the hydraulic pump. It is in good condition. The o-ring on the pickup tube in the differential housing was replaced along with the safety relief valve.
The steering pump was inspected and was found to be in new condition.
Some other problems we repaired were:
The park lock was broken and was found at the bottom of the transmission.
The PTO oil pickup screen was plugged the PTO was not operational.
The installation of the MCV to the tractor is being completed.
