As with a lot of things, package quantity is the kicker. I think the o-rings were two in a package, I don’t remember the package size on the washers, and the gaskets were 5 or 10 in a package. M dealer added them to a bin location and then sold them individually to me.
It helps that I used to work there, before they became a part of United Ag & Turf. Google the part numbers for a range of prices, but the gasket shows at about $34, and that sounds like what I paid. Pretty pricy, but they look like they are made of asbestos, and that price probably reflects special handling they have to do. The rest of the parts were reasonable, though.

Correction: The washer part number is T24599. I typed it wrong with two T’s. Sorry

Thanks for all the replies everyone. It may be smart to just buy the seal kit and do them all at the same time.

 

[materthegreater]

I finally smartened up and bought a seal kit for the whole pump.

A little progress here, a little there. How old do you suppose this new filter is?

 

[Welder Dave]

What happened to the tag on the IP? It looks sand blasted or something.

Corroded

 

[Welder Dave]

That's an odd place to be corroded that bad. Do thy use a lot of salt on the roads where you are?

 

[materthegreater]

Yes, more than a lot. But I'm guessing that tag got corroded from a mouse nest or something. It's close to the side cover and this machine sat for quite a while before I got it.

Interesting that these old Wix filters have the Dana logo on the box:



I resealed the berm leveler cylinder since it would leave a puddle wherever I parked the machine. The rod is a bit banged up so I filed off the high spots and called it good enough.



I'm not too familiar with these Perkins engines- does anyone know what this thing is? It appears to have one line connected to the cooling system and the other to the engine oil system.

After bleeding the fuel lines it fired right up and purred like a kitten. I was nervous about doing the pump myself but found some very useful videos that showed a lot of detail. Here's the first one:

Looks kinda like this Perkins


4.203.2 according to my book.

 

[Welder Dave]

I think it's a 4-236. Very popular engine. Be careful watching video's on IP's. There are a couple the pumpguy says are wrong and keep him busy.

 

[MarcusZ1967]

My bad.. that motor that I pictured is a 4.203.2. Just looks similar.

Dana hasn't owned Wix since early 2000s, so that filter is at least 20 years old I'd guess.

After watching Area Diesel Service rebuild pumps, I can't think of any I could do myself and be "good".
The calibration bench is $$$$

What's the difference between a rebuild and reseal? I didn't replace any hard parts, just seals. However, it seems that I must have put a spring back in incorrectly because the governor doesn't seem to function quite correctly now. The RPMs drop down considerably under load.

 

[Crux]

I have same machine, same engine.
One thing to check is the shaft from front of engine harmonic balance to hydraulic pump and air compressor.
Found splines severely worn. Steiner tractor has shaft and hub.

I always thought lavender was made by magical ‍♂️ ‍♀️ or something. Never seen a grader like that. It seems to do a good job. In my experience, if it looks good, they always say that machine does a nice job. If it looks bad, they tell you you're not much of an operator.
