B1750 HST service manual

[jkk04]

Hello, Members.
I just got B1750 HST 4WD 2450 hours need to have service and parts manual.
It runs good and no oil leaks any points.
This newer tractor is for upgrading from L1500.
I am trying to replace all oil and hydraulic transmission fluid etc..

If some one has it, please share to me.
Thank you
Jkk

Thank you for link.
Just downloaded the parts and WSM.
Another question is the HST fluid filling plug.
I see fluid gauge (orange arrow in the picture). Green arrow nut is the filling port?
the operating manual is not clearly described for filling port on HST that makes me confused.
Thank you

Green arrow nut is the filling port?

Negative, the fill port is right next to the dip stick, with the hose going to it.

Check this out.

 

[jkk04]

Check this out.

Thank you so much.
Will update once all oil,fluid changed

Also, I am wondering how to buy HST cover. It is missing and prior owner even didn't know where it is.
I couldn't find this part number in the parts book.

Thank you

The most important 'servicing' job for this model is to clean the metal mesh filter for the HST. Its a 'pre-filter' for the HST tranny. They can clog badly, cause oil starvation, seriously reducing the power of the HST and possibly significant damage. Its on the left side under a 'banjo' type oil line connector. All you will see is a bolt head. Its best done with the tranny drained. There's another mesh filter on the right hand side that does the power steering.

See the parts diagram for the b1750hsd at http://kubotabooks.com/
Page 113 part 030, and page 118 part 070 (Thats the printed page numbers not the pdf page number).

Clogging is not just caused by dirty oil. The theory goes that the oil is baked onto the filters or is 'cracked' by static electricity. I read somewhere that thats why they stopped using these types of filters.

Very good information. I knew the left side mesh filter for transmission but right filter for power steering.
Even no described on operating manual.
Will clean both filters while replacing fluid .
Thank you

It's highly unlikely you can still get that part from a dealer.
But they do show it as avalible:
P/N 66417-53110
https://www.colemanequip.com/parts/details/KubotaParts/COVER-SUB/66417-53110/

4 Knob bolts P/N 01820-50615

If that doesn't work, you could try these guys:

Replaced engine oil and transmission fluid.

The strainers for both side were not bad than expected.
Now, having problem on the transmission forward backward engagement.
Right after fluid changed let tractor runs more than 15 minutes.

The loader and 3 point hitch raised up slowly but engaging forward backward was not at all.
Therefore, let the tractor runs another 10 or more minutes. now the loader and 3 point works fine but forward backward engagement is not works properly.

It makes growling sound when push the pedal forward and backward and hard to engage.
It seem like about 1/2 gallon pouring the fluid was less than removed fluid but
the fluid gauge shows normal.
Any your suggestions and experts will be appreciated.

Low oil.
Air getting into the pipes that you removed.
(Growling would suggest the two above.)

Brakes locked on.
Transmission selector not fully engaged.

Thank you for your suggestions.
It works ok now but still making growling sound.
Actually it was making growling sound whenever push the pedal either side before I got.

you suggested low oil-------I tried add more oil but over flowed from fluid check gauge.

air getting into the pipe------- I dont think it can be happen.
Anyhow can bleed the air?

Transmission selector not fully engaged--------anyhow can adjust engagement?

How about malfunctioning the main hydraulic pump that makes low pressure?

Thank you again.

These things are well known for squealing and making nasty noises so it may be nothing to worry about.

I didn't mean that the tranny selector needed adjusting. I just meant that you should check that your 4wd/2wd and rabbit/turtle levers are properly engaged.

Regarding air in the lines. You cant bleed them and you dont need to anyway. Just make sure the banjo connections are properly sealed. As I remember they have some thin O rings or washers that you need to be careful with.
