Valve adjustment: DIY or Dealership?

[dfkrug]

Yep...........if one tire of two tires on the same axle gets below a certain psi............
you gotta change both tires.

Ouch. (3 things of little value to a pilot: the runway behind them, the airspace above them, and the gas on the
ground.)

RE adjusting valve lash on a tractor, the last one I did prob had never been done, and, at over 2000 hr, two or
3 of the 6 valves were out of spec. Barely.

I believe most would agree engines will continue to run for many miles/hours on worn valves before any kind of catastrophic failure or need for overhaul, but there WILL BE a loss of performance.

Valves aren't going to wear in 200 hrs, 1,000 hrs or hardly noticeably, if at all at 2000 hours in a modern industrial diesel.

2000 hours in a car that goes an average of 45 miles per hour, will be about 90,000 miles. If you drop the car's engine speed to that of a diesel tractor, about 1/2 or less, the diesel will have run an equivalent of 45,000 miles in 2,000 hours. I'd guess that the average car during it's lifetime runs at less than a 45 mph average so the equivalent diesel mileage would be even less, probably more in the vicinity of 35,000 miles. You're not going to wear out a valve in that kind of running time.

Worn valves can, as you say, cause a lose of 'performance'. What the severity of that condition is up for debate.

I'm driving a tractor, not a Maserati, so I'm not looking to gain one second across the field or save an ounce of fuel every week or so.

Once again, with all due respect to everyone here, I say fugedaboutit.

thank you, you proved my point.

Agree,

My 4 banger Mitsubusi in my Excavator has +5,600 hours, No sign the valve covers have ever been off. It burns about as much oil as my 2014 Subaru. Runs quite, almost like a gas engine. Younger, I'd check it, being olde fart, "ani't broke, don't fix it", (unless you fly in it or race it!)

Anyone know the valve adjustment on a 2415 Malinda tractor

Mahindra sorry for that

Page 21 has those specs for you. Manual is for a 2015. Tractor data says 1815, 2015.& 2415 use a Mitsubishi S3L 1.1L engine.

Interesting that a valve lash thread would show up just now

I've been giving some long needed attention to the Fordson E27n, and had been laying awake nights trying to come to grips with whether I should check the valve lash. It has not been done since I had the mains and rod bearings re-poured along with new valves pistons and rings done over 20 years ago by a specialty shop down in the Boston area.

Of course my concern is that the lash will have gone to zero and a valve no longer seals or self cleans. Certainly "peak performance" on that tractor is not measured in absolute horse power.

It's just such a PIA to get at the adjusters behind the intake/exhaust manifold. The entire setup really needs to come away, but that may damage the gasket (spring rings on the ex) Such spares are getting difficult to come by.

Anyone know where a Fordson Tractor DEALER might be where I can just take the tractor to get this service done?

;-)

All in good humor

Interesting that a thread started in 2015 turns up data for a 2015.

If it has the MHI S3L here’s the procedure. I have MHI operations and services manuals and it calls for checking valve clearance at 500 hrs intervals. Did mine last year and a couple were out of spec. See section 8 of attached service manual

 

[doneill127]

Heres a link to a my previous post

Max/Mitsubishi S3L Valve adj.

My owners manual does not show any recommended valve checks or adj. But the MHI Owner manual and Service manual recommends checking them every 500 hrs. So after finishing up an oil change decided I'd check mine(490 hrs) Recommended clearance is .010. Found one at .002, a couple at .006 and only...
