KAMA 454 Hydraulics drain location?

[Paddy]

I can't see any location other than the stainer or a fitting attachment. So if anyone has an idea

If I recall, it's one of the hex heads behind the seat. Look above and to the left of the PTO output shaft. It's probably the one that looks out of sequence with the others.

Do you need any spare parts by the way? I traded my 454, and have lots of unused KAMA/TaiShan spares on the shelf

hi greg

As I recall, you did not have a FEL? Again recalling, that maybe the FEL used the drain plug as the location to tap in for the return?

here is a photo of the back side. The gold fitting in the upper right might be the spot.

PM with what you have with regards to parts.

You're right about the loader, that was on the TS354C. But I also had a PTO-driven hydraulic pump and PTO safety shield on the KM454, so yours looks a bit barren compared to mine. I should have looked at my own photos first, that location I have you above must have been from one of my Jinmas. So from what I see, it's apparent that you'll have to drain via the filter housing. While we're on the topic, among my KM454 spares is a spare magnetic filter frame and lots of 80x80 brass mesh to wrap around it.

The site PM system is a bit awkward for a spare parts discussion (the list is long), but you could PM to me your regular email address. Once I have that, we can go from there.

Greg,

was your PTO hydro pump after market or is that the way it came from the factory? Mine is up front with the power steering pump? I see where yours is mounted and I also have a square cover plate plate. So I assume I could have one of my pumps there as well. But, does the PTO have to be engaged all the time? I would assume not because you would lose hydro power when you depressed the clutch.

The reason I ask so much regarding your pump is the fact the KAMA has a relitivly low out put pump. I looked into upgrading to the larger pump but the clearance to the radiator is just to tight. I have a Prince PTO pump that came with a old backhoe I plan to restore "some day".

Came that way. You must have a smaller starter than I had. Can't find an old photo, but on my KM454 there wasn't enough room to stack a 2nd pump between the PS pump and the starter motor. 2nd pump housing would have come dangerously close to the starter/solenoid electrical posts.

That Aux PTO shaft is independent of the clutch. I can't remember now which was which, but either the KM454 or the TS354C had a engage/disengage lever that sometimes got inadvertently disengaged by my left heel. Soon as I lost hydraulics, I knew that I'd accidentally kicked that lever.

I'm pretty sure your Prince pump is made to be mounted on the regular PTO output shaft. That said, the hardest part of your idea might lie in getting it adapted to be driven by the upper shaft. It typically takes a separate coupler. You'll also need special fittings to route the fluid in and out of the hydraulic sump. I do however have old photos of them, I'll include some when I email about parts.

I drain mine at the loader return port.

 

[Paddy]

Brad,

Thanks. I thought that was where a plug must have been but, used for loader return.

 

[greg_g]

FWIW, I still recommend draining at the filter side. There's a magnet inside, which I liked to clean at least once a year. If necessary, I also change the filter mesh (80x80 brass). To clean the magnet and change the mesh necessitates draining the fluid first. So I just kill two birds with one stone.

Didja get my email with the photos and parts info?

Yes, on loader valves with power beyond, the drain plug is removed and an adapter is installed for the loader return line, the power beyond line is attached to the 3 point lift. You have to remove the hose, then the fitting to drain the hydraulics. Some loaders have been installed without power beyond so the drain plug is still available. same on both TS and KM series KAMA tractors.

Chip,

So if I understand correctly, when operating the FEL, the hydraulic fuild does not go through the strainer on returning?

The reason I ask is I'm installing a filter on the return line where it enters the strainer, left side. (There was a rubber 90 there that was cracked)

Skip that last post i made. after looking the hydraulic system over more closely, I think I understand it beter now. while draing the system, I thought I'd install a spin off lenz hydraulic filter. I saw 3RRL modification where he removed the strainer housing and tapped a 1 in thread. Then he Tee'd the Rear remote return with it. It is all on the suction side.

Looking the tractor over today I think the best place for the fiter is on the rubber joint on the 1' suction line about 2 feet before the pump. It does run low along the engine but I'd plan on turning the filter horizontal to keep it out of the way.

Anyone see an issue with that? Is there a certain distance a fiter should be placed before the pump?

The issue I see with that is that a filter should be on the return to tank line, not the suction line. On a suction line to the pump you can only have a coarse strainer (like 80-mesh) or you risk causing cavitation in the pump from starvation. On the return side, however, you can go down to about a 10 micron or so filter safely and get far better filtering.

Yup, and the KM454 already has one. Unlike the one inside the Jinma sump, KAMA/TaiShan put it on the outside. The photo is of Paddy's tractor, the backside of the suction screen housing is visible inside the orange circle. Remove those two bolts, the suction screen comes out (along with all the fluid in the sump). The suction screen consists of a magnetic center cylinder that is wrapped inside 80x80 brass mesh

I agree, I would never put a filter on the suctions side. RETURN side only. A stainer is ok on the suction side but not filter. You are just asking for troubles.
