Muchmore Trucking Posted July 8, 2017 Share Posted July 8, 2017 Hey new to this forum.. ive got a 1980 r model with a 237.. I have a leak from behind the injector pump.. hard to say if its fuel or oil? after truck sits over night, it takes some cranking to get it going the next Moring. once its running it runs mint all day.. obviously losing prime... just looking for some help. also is this a 2 or 4 valve truck? Truck uses 1 gallon of oil a week. Also getting oil in air tank.. any help would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
thomastractorsvc Posted July 8, 2017 Share Posted July 8, 2017 If losing prime check the transfer pump there is an inspection plate behind the pump check the tightness of the cover bolts you may not be able to get on them just have to see oil in tanks is a worn air compressor as long as you build air like you are supposed to keep the tanks drained and save up for the compressor Probably a two valve the valve covers are rounded dome shape if they are flat then 4 valve Quote Robert"I reject your reality and substitute my own."
