D 14 engine question

when running the oil pressure is good but after it warms up it goes to about to the line of having no oil pressure.

 

oil pump screen look okay I pulled the pan this mornings as usuall there was about 1/4" of old grude oil.

even though i have change the oil twice.

 

I now the WD and WC motors will do this if the cam bearing are worn is the D 14 the same.

or is there something else to look for i will be pulling the

motor and check all the rods and mains also.

 

 

 

 

Pull the existing filter/oil, refill with a good quality straight 30 wt., the Seafoam and add a rare earth magnet to the drain plug (Radio Shack has the small magnets).

Run a good thirty minutes with the new oil and Seafoam, after getting the engine up to operating temp. Shut down and change the filter, run another 15-30 minutes, then drop the oil and filter. Refill with the good 30 wt. and a new filter and go work the tractor for a good hour or two, keeping an eye on a good gauge for the oil pressure throughout this process. Pull the valve cover and you should see her looking pretty clean; good time to check the valve clearances at this time.

Change the oil and filter again after five hours of use, good, hot use.

I start this on a gas unit by removing the bowl, cleaning everything up and rinsing the tank at the time, then adding 5 gallons of fresh gas and a can of Seafoam in the tank.

I do this with the oil gradually as seen a friend years ago ruin a good 429 in a boat, don't remember what type of cleanout he used to treat the oil after buying the boat but he added the treatment and took the boat out onto the lake and flogged it for a good hour.

He cleaned out the old deposits in the engine for sure, but the pickup screen was plugged with deposits and starved the engine of oil and it was junk.

I run Rotella diesel oil in everything I have for gas engines, after getting a good baseline by treating as above.

 

Also the crank will need grind and take the piston out today and sleeves.

 

The picture of the head look how much stuff is in there  has stop up the little pipe

going to have this hot tank along with the motor.

 

 

 

 

 

Connecting rods are offset;numbers 1 and 3 having long part of the bearing towards flywheel;numbers2 and 4 long part of the bearing toward timing gears.

 

In the D17 section it says all piston pin clamping on cam side but not in the D 14.

 

anyway it will get all new parts the sleeves are to loose for me and scored.
