100 hrs service and look over Mahindra Max 28XL Shuttle with ML205 Loader

After I finished my Loader Cylinder upsizing I did the complete 100 Hour Service on my Max28.

I hope other than grease and fuel, I do not have any maintenance for a year or so.

I used a Mahindra engine oil filter for this oil change . It is a far inferior filter to the K&N HP1010 filter that I Installed at the 50 Hr Service. I would have most likely been better off not changing the filter.

Front Axle oil change was straightforward. The axle capacity is just over 3 quarts.

There are 3 Drain plugs for the Hydraulic oil, a main and drains at the bottom of the bevel gear housings.
I have been unable to find a X-ref for a aftermarket hydraulic filter for the Mitsubishi Tractor.
The Tractor takes a bit over a five gallon pail.

I cleaned the air filter blowing compressed air from inside out, then blowing the outside clear. There is no Pre-filter.

Do the fuel filter last, as there is no shutoff to the fuel filter or vent. The Fuel Filter assembly is a cheap plastic unit that will spill diesel fuel. I used the spilled fuel to clean up any spilled oil. That is why I suggest changing fuel filter last. A 5/16 shut off valve is on my list to add.

Grease the pedal pivots, there are 4 grease fittings. There are 4 Grease fittings in the Front axle Tie rod/steering assembly.

About ½ the front end loader frame attachment bolts were loose, some completely loose, especially the difficult to reach ones Others were just a bit more than hand tight, and some were tight.
it seems poor quality control, as the bolt heads were marked with a black vertical Sharpie line, just to pretend that they were checked for tightness??

I noticed the Max28 has a cast iron front and rear main casting section of cast iron. Axle Covers, and the Center section of the tractor are aluminum

Overall build quality is good, but here and there, there is evidence of cost cutting, even for a basic tractor.

No one can find a hydro filter xref. I've looked very hard myself.

My fuel filter bowl drops a shutoff valve when it is unscrewed. I never lost a drop. Watch out for the little o-ring that sits in the middle top of the filter. Real easy to lose or overlook.

BTW, your engine is the same as my 3016.

So the shutoff valve is internal to the plastic housing?

On the hydro filter, I'll try to determined the thread of the base and see if I can do a match up. It is a longshot.

I like the K&N HP1010 filter has a nut on the end to make removal easy.

Sounds that way Mike, it must seat when the housing is loosened and taken off.

It appears that way, although I never took it apart. I was stumped as to what to do about shutting my fuel supply off when I was about to change mine. The manual said nothing about shutting off fuel supply. I put a bucket under it and hoped for the best.

I unscrewed the bowl and NOTHING came out ! I didn't probe to see if there was a valve but there has to be.

I replaced the filter and almost missed the little O ring on the top of the old filter. The new filter did not come with a new ring.

When I put the bowl back on, it filled with fuel.

I'm guessing that it's one of the reason that the manual says there is no bleeding of the lines necessary when messing with the fuel system.

I was very surprised and happy. It's very ingenious.

I searched all over for xrefs on the hydro filters and it seems no one makes them. I wouldn't worry too much about finding one. I found that all the OEM filters from my dealer are as cheap or cheaper than the xreffed versions. I wasted a lot of time trying to find the xreffed versions. I would expect the hydro filter would be about the same price as the oem, if available somewhere.
