Yanmar 186D loader hydraulic filter

[suburban99]

Hey all just bought a Yanmar 186D with a KMW loader. Model is K650.
Tractor has a PH8A filter remote mounted for what appears to be the hydraulic system.
I know that a PH8A is a ford motor filter. Is this the proper type of filter for this application?
Here's some pictures. thanks

Nice!! If that's what was on it. Who ever set that up new what they was doing. Not big on Loader manufacturers but looks to be well built!.....

Ph8a will screw on to many hydro systems from what I read but it can bust cause it's burst pressure is not as high as a true hydro filter. I have also heard brought up that point that it can suck it closed internally due to the increased pressure. I would buy a true hydraulic filter for it.

I have the same bush hog. That was before they put the big yellow sticker on it.

Well don't put one on there again. Me or the prev. don't know what were talking about!! It may collapse or explode........ Sorry about that then:confused2: And just gave the Prev, a :thumbsup:

I'm not saying remove it today cause you can die in the explosion. Just that when I replaced it I would use a proper hydro filter. It would suck to have a filter bust while you were trying to get a job done on a Saturday.

:laughing: Have to find KMW. Ontario I noticed... A little help but nothing I've found on FEL.. Just go to NAPA and get a Generic match would be safest............. That ones been on there awhile and that little loader not all that much..

I'm thinking that is the original YFL650 loader which was the 'Yanmar' loader for the YM186. The loaders Yanmar used were made in Canada from what I remember. I have not seen any with the KMW brand on them before but it sure looks a lot like (ok... identical to) the YFL650.






The filter setup is just the regular YM186 hydraulic filter.

The filter is on the suction side of the pump so no fear in the filter over pressuring and blowing up. Aaron can correct me but I believe the hydraulic filters should be in the 20 micron area. Using a filter with a small micron rating could lead to starvation of the pump.

I got curious (also own a YM186D) and found Baldwin lists the hydraulic filter for this application: Baldwin B2. Baldwin shows it is a broad-application oil/hydraulic filter.

Then back into NAPA's crossreference table. NAPA's version of B2 is NAPA 1515.

Specs on NAPA's site:
Link: Part Details
including :
Height: 5.197"
Max Flow Rate: 7-9 GPM
Nominal Micron Rating: 21

This seems to be the oil filter widely used by Ford and others '57 to Y2K.

(I see also Baldwin mentions a similar 'short version', and NAPA has a similar '2 quart' version.)

Good work guys. Confirms the Ford filter will work, as long as you don't buy Frams which go down to like 5 microns I guess if what Winston said is true.

I am in Canada as is the tractor. Could be they attached them here when they were imported. There is no Yanmar marking on the loader, but it is identical to those pictures.

Aaron (Hoye) has it right according to some research I did on my backhoe after I bought it. KMW built the 'OEM' attachments sold by Yanmar USA (which I expect includes machines sold in Canada). Since these are identical loaders with the same model #, the difference may be only the year sold and that ID tag.

Related, my backhoe was sold as 'OEM' by both Yanmar-US and Kubota-US for a few years about 1980. The only difference was paint color and decals. I'm pretty sure KMW built it, too. Somewhere there's an old post where I described my research and conclusions. It might also be the same backhoe sold as OEM John Deere, since the only place I could find replacement bucket teeth, had my teeth listed as made for Deere's backhoes and nothing else.

I found that KMW was sold/merged into another firm long ago.

At any rate, for Yanmars sold around 1980, the 'OEM' backhoe and I assume the loader use generic SAE-spec parts so any hydraulic shop in NA can service them.

Can someone post a picture of the loader handle and linkage as mine looks homemade.

 

[California]

No that's the real thing. My YM186D has the same monkey-motion linkage. Not as corroded but not clean metal, either. Your cast aluminum (?) handle looks more professional than what I have. I'm home right now but as I recall, the handle on mine is just sheet metal bent to similar shape.


Edit: I found a 2014 photo, where I replaced the loader's quick-connects. This enlargement shows the linkage like yours - and the cheap but satisfactory handle.

 

[suburban99]

Too bad such a good tractor loader has such a janky handle...

 

[Jtullis13]

I agree with California, that looks really corroded. I don't know how easy it would be to repair that or look for a different valve.

 

[suburban99]

Anyone have a parts book for the loader that they can share? Or know the brand of the loader valve?
I would like to repair instead of replace...really need the swivel piece as that is quite worn.

Yup, I just picked up here in Canada 226D and same funny handle to operate the bucket. Good info guys.
