B8200 HST transmission

[PeteW]

I recently bought a B8200 HST, a bit on the rough side. Transmission does not seem to take much load before it ceases motion. I drained the transmission oil and found some iron filings on the screen. I also got a 7mm ball bearing. Guess it doesn't look good. appreciate some insight !

A free parts manual from here might be handy... Kubotabooks.com

Blocked screens can certainly stop a tractor. But iron filings don't automatically mean major problems. And the ball bearing could just have been dropped by someone on the assembly line. I'd just clean the metal screen, replace the spin-on filter and the oil, and cross my fingers. I had a similary sluggish tranny. Cleaning the screens made a world of difference.

Are you in low range and it stops? Does the trans slip or stall the engine?

 

[PeteW]

No, it does not stall the engine. It just stops moving like when confronted with a a bit more steep ground. i.e. it slips.This can happen in low range too.

What shape is the clutch in?

 

[pdowling1]

Every clutch I ever ran across was round!

 

[Egon]

Do run across them on the road or in town?

 

[PeteW]

Love you guys sense of humour. Or should I spell that another way!

About the clutch- might be slipping a bit. I've not had HST before, so don't know what the norm is. If I try and shift speed range with higher revs, it makes a noise i.e. cogs trying to mesh or something. Drop revs down to idle and it goes through clean and quick.

 

[Egon]

Will it pull a dead weight.

Any strange smells when it doesn't move?

 

[rdsaustintx]

I would want to know where the ball bearing came from! Would try to find an assembly diagram and parts list. Might be a real clue in that.

Then again, I don't even know what a B8200 looks like.

How's the weather in New Zealand? Every time I do a search on my geneology (Scottish lowlanders), it appears most of them went to Tasmania.

 

[PeteW]

No smells. have not tried pulling on a dead weight, but will do so.

GREAT weather here at present, mid 20s C daytime and 14 - 15C night. wonderful for the summer school holiday makers, but up in North where I am not so good for us in the country as been below normal rainfall for past several months.

Spent 2 weeks Tasmania not long ago. Nice place, worth a visit, you'd track down your distant relatives very easily

If I were rich (not a likely scenario) I would love to winter down there. I hate the cold. Plus whole new set of stars to gaze at. Sigh.

Figure out where that ball bearing came from.

 

[PeteW]

No smells.

Good idea - I will try against a dead weight.

Great weather here. Mid 20s C day 14 - 15 C night. Summer schol holiday makers very happy, but we out in the country not so happy as lower than usual rainfall past few months.

Tasmania is worth a visit. if you went there, you would easily find your long distant relatives. It is a small place and everybody knows everbody.

Mid '80s forerunner to the B2150, and later the B2710/B2910.

I would start with the fluid and filters. Clean the strainer. Sounds like you did some of that already.

The clutch gets used so little on the HST... I would worry more about it sticking than about it slipping.

Can't tell from you message; you are changing range while at a standstill? Make sure your HST pedal is in the "neutral" position? If I am not stopped, or they HST pedal is slightly depressed, the gears complain when I switch ranges.

This is only a 19HP tractor. It is built like a tank, but does not have much power. High range is useful going downhill with a tail wind. I generally run mine in mid-range. Even with that, a hill will slow it down. Low range grunt is pretty good, but slow...

It is really a big tractor for a 19hp motor. Especially if you consider the newer, same size "B" series had 27, 29, and 32HP.

I looked in my owners manual and service manual. They do not say much of anything about HST(this tractor was made in gear version too).

You drained the fluid, from the fluid drain below and to the right of the PTO? You changed the hydro filter under the left fender? And cremoved/cleaned the strainer, located on the underside of the tractor, kind of below the range lever? Fluid is full, using the fill port under the left front of the seat. Dipstick is under the right fron edge of the seat? If drained completely, you'll use about 4.5 US gallons of fluid(manual lists 18 litres).

I have used Kubota UDT, as well as Valvoline hydro fluid from the local car parts store.

Have you used a HST before? You know pressing more on the HST pedal will bog it down, not make more torque(ie it is not like a gas pedal). Pushing harder may make the tractor go fast with no load, but will bog it down if there is a load. When I first got mine 10+ years ago, I had to get used to the HST; I tried to drive it where if I needed more power I stepped more on the HST pedal; exact opposite of what should be done.

Since it is only a 19hp tractor, I have found it is real important to
- keep the radiator screen clean so it does not run hot
- keep the air filter cup cleaned out
- keep the air filter clean
- keep the HST/hdro fluid full, the filter and strainer clean

I have the owner manual and service manul right here. I can try to look up info if you need. It is printed with a gear tranny in mind though.

Texas Hill country is cold?! I've been in Austin and environs in FEB and it ain't cold, maybe in Jan? (Sorry, I live in Maine)

love the humor...
Thanks Frank in France.....
