I have a Mf 254 or 253 that has a clutch switch and the wiring is messed up so i cant tell what it does.I would think its for not letting the pto turn if its in gear while starting the engine.

A man that i worked with a few years back had a 02 E7 that was same way.It would start cold but not hot.i check the voltage at cranking and it was holding at 10.5 volts.I did not have time to do any more being i was trying to run a dump truck my self so i told him to take it to mack.First thing they did was replace the starter and no more problem after that.The strter sound like it was turn engine good to me when hot but any way he be ok now.

That is what the dealership here uses.

At least the skeeters will leave us along for a few days.It was 4 degrees here last night.

He is saying it melts the pistons.Fast timing puts more heat in the pistons because the fire is on top of the pistons longer with fast timing.Slow timing is a cooler piston but hotter valves a exhaust is hotter after it leaves the heads.

I was thinking it timed at 8 degrees

That engine does not time fast so maybe the timing marks are incorrect.

Sucking air in the intake as well as fast timing will run exhaust temp hi also.Also hi compression due to over surface head or block is not good for it.

Well called them jar flys.We also used the lavas from a wasp nest for fish bait when i was a kid.

Fish bait

I see that engine has a perry water filter on it.

The cam is different on a air locker than a auto locker.Check that out.

I think she was sweet on Barry.

This truck did have shutters till i installed a 285 engine and the cooler tubes go thru the headlight panels and connect to the larger air cleaner and to the intake.This was a single axle truck that i installed a box on the back and made a camper for hunting.It was some spared parts i had.I installed a eaton ten speed and a three speed behind it for more speed.

Here is my B model with a later engine and air/air cooler on it.Its a KW cooler turned up side down.

It dont hurt my feelings

and larger brgs.

I would be only guessing on this but i tought a 285 was always a two valve

Me also to

I have a B 61 now and i put a 285 in it years ago.It has just two spin on filters on it.Both are full flow and no by/pass.The starter is on the left side also.Pleny of room.

Some times on a cummins 335 by 200,000 it need a set of brgs or worst.On all engines oil filter systems got much better as well as oil. On a 335 cummins and even a FFC engine a oil system was designed to by/pass the filter with a 15 lb differengal by/pass valve spring.This means if the out put of the filter was less than 15 lbs of the input then the by/pass valve would open and let enough pressure by/pass the filter so the engine would get full pressure.The problem with this is ever time the engine is started the oil can by/pass the filter and what ever the cold oil picks up from the pan to go thru the system.When the Big can engines came out the oil pump had a 120 lb psi relieve valve in the pump and a better filter element that will not destroy its self with the higher pressure.The filter now has a 55 lb pressure differential by/pass valve spring on it and this way the pump almost makes all oil go thru the filter at start up.But after the oil enters the engine there is a sense line connected to the pump from the oil galley and this way the pump will even its self out to filter all oil an maintain enough pressure to fed the system which is about 40 psi. 800000 is normal now for brgs on most engines.There is other things that help a engine of today get more life also like engine timing.

I cant remember if it can or not.If that engine was the ENDT A or B or C it could be.

That is a full flow made by luber/finer.

>002 is as big as i ever honed block to and i think if they need more honing we pulled them out and sent block to mach shop and let them bore to maybe .020.

You are correct on the .002 over size.I have hone that much out of the block before and it takes some time.I remember our red headed night foreman as homing a block one night with a maybe 3/4 drill motor that was very slow speed.i saw him run the sun hone too deep in the block and hang the crank which in return stop the drill motor by slapping him in the cods with one of the handles of the drill.He set down on the fender of the B model and just set there.I say do you hurt and he say yes then he drops his pant to find one cod with no skin on it.Thats when i started to hurt. Those old END 170 engine was bad to deform the block bore.Later engines with the 20 head bolt heads was not that bad and they let the liner be installed some looser.
