Tractor Repair: motor rebuild, valu bilt, ford naa
Questionhi danny, i am from catskill n.y. 20 mi s. of albany. i was given a ford NAA. it had a bad motor, i bought a long block from valu-bilt. knowing nothing about motors i enlisted a friends help in installing and getting it to run, which it does, how-ever. he heard a lifter out of adjustment and removed the valave cover. he says there is not enough oil getting up to the head.( rocker assemblt looked dry ) a small amount from the push rods is evident but he thinks there should be oil comming from a pickup tube into the rocker assembly. this is not happening. we have great oil pressure to the guage, and heve spun the oil pump with an electric drill and screw-driver bit, but no oil comes up this tube to the rocker assembly. another farmer in the area says there is not supposed to be, and the oil from the push rods is sufficient. what do i do?
AnswerJason is there any oil holes coming up to the rocker gear in the rocker assembly.
If there is ,the oil flow should be good out of it if there is not the flow up the push rod tubes should be good enough but again I am not sure as it has been a long time since I have done work on this type of engine.
I hope this helps with your problem Jason.
Kind Regards Danny Last
