I bought a 1959 Fordson Dexta off a Dealers back lot it had been setting there a few years. He said it was a trade in and he had no Idea what all it needed. Well I plunked down my $350.00 and he had a worker help load it on the trailer. I got it home put a battery in it Checked the water and oil put fuel in it and it started. I sounded good smoked leaked fuel. None of the gauges worked so we shut it down and started repairs Hood, Fenders, radiator, fuel lines, lights, gauges, key switch, paint, Change oil and filters! Thinking we had everything ready we put the 501 Ford mower on it heading for the field the oil pressure kept dropping from 40# to about 8# and the rear main seal was leaking. How hard is it to rebuild the engine, replace the cam bearings, replace oil pump, replace rear main seal? Thanks to all!

What weight of oil did you use ? Should be HD 30. If you used 15-40 that could be the problem.

May be worn oil pump, you can check that by removing the sump,
and with the sump removed it is also easy to check condition of con. rod bearings. The original pump of my 1959 Dexta was no longer available . The new pump supplied by perkins needed new connecting pipes. Cam bushes usually no problem. Rear oil seal leaking is common.
Somewhere on the internet is a very good site regarding a complete Dexta overhaul , when found will post this in new message.
In fact you need a service manual to make good job.
