Satoh S650G Maintenance Parts Info

[rolape2]

Transmission Oil is listed in maual as 80W and 4.49 gallons. I justed changed my Trans oil and they do mean 4.49 "GALLONS". Also manual says 80W for hydraulics, others on this forum says JD303 / Universal tractor trans hydraulics fluid which is 10w20 (from label on UTF) big differance. What is evryone using?

Hi rolape, I don't know if your question regarding hydraulic oil has been answered but I have a '77 Bison w/Mazda PB100 engine. My operator's manual calls for hydraulic oil, SAE 20w or equivalent, (10w in extreme cold climates)....I can confirm all the other ignition/maintenance part #s posted by other members also....I have gotten 28 yrs. of great service out of my Satoh....thanks to all members (and the internet) I won't let my Bison die.

It appears that this engine was not used in any cars imported into the US. All Mazdas I have found had larger displacement engines. This is actually a 987 cc engine, and I recently purchased a head gasket from a dealer in Australia. He has some other engine parts such as pistons, bearings, valves, etc. Try contacting
dean@autosurplus.com.au for more details.

The same engine seems to have been used in the following Mazda Australian models as well as the Bongo.
1000 Sedan 1967-1968
1000 Pickup 1967-1978
1000 Coupe 1966-1968

I am not sure, but Valley Power can probably supply lots of parts too.

Another possible source is
Homestead Tractor in Apple Valley, CA. (760)240-1610

Leonard Schafer is another source, located in Illinois I think. He is mentioned in other posts on this fourm.

Newbie here. Haven't even completely filled in my profile yet. I am in the OKC metro (Edmond, just north of the City).

Although I have extensive mechanical and fabricating skills, this is my first tractor. It is a 650G and I just got it this morning. Seller says I should change the hydraulic fluid, bc he doesn't believe it has been done in a while. I know to use either JD303 / Universal tractor fluid, but how much?

I am sure this has been posted, but I didn't see it. Sorry if I just missed it.

Was going to go by my local tractor supply and get a 5 gallon bucket of fluid. Will that be enough?

I also see there are several sources for service manuals (copies of originals) and they seem to run anywhere from $35 to $50 for the copies. Any chance there is a downloadable online? Also, the zip file in the very first post on this thread won't download for me. Any ideas?

Thanks in advance for any help. Looking forward to learning from you guys.

Just out of curiosity did your head need any rework milling cracks etc done i just learned the hard way my radiator should have been cleaned out prior to heavy high grass mowing pretty sure i have at miniumum blown head gasket and concernned what all damage i might have done to the head etc.

I believe all mine needs right now is a choke cable (purchased but not yet installed) and the hydraulic fluid changed.

Anyone know how many quarts or gallons I need. It is a split system, so it is not the transaxle fluid, just the hydraulic. No power steering, just a 3 point.

Thanks.

Lynn, you've asked several times and nobody has answered. I don't know the answer specifically, but my Yanmar YM240, a slightly smaller machine but with shared transmission and hydraulic fluid takes about 4 gallons. My International 284, roughly comparable to yours, since it has an engine from the same family, uses 13 liters, about the same. It, too, has a shared hydraulic/transmission fluid system.

The Nebraska tractor test doesn't list your hydraulic capacity, but I'd be really surprised if 5 gallons didn't do the transmission and hydraulic system both; it should almost certainly do the hydraulic circuit. Post back here when you do it, so that we can have access to your information.

This is from an older post:

You mentioned a drain plug. Where is the drainplug located? If you removed the one on the belly of the tractor, you drained out the 80W-90 gear oil from the transmission. You may already know, but he 650 has a seperate reservoir for the hyraulics and the tranny. Tranny takes 5 gallons of 80W-90 gear oil. Hydraulics use approx. 1 gallon of universal hydraulic fluid.

 

[LynnBilodeau]

Thanks guys.

I will plan on one gallon. I will definitely report back when I am done just to confirm the info Edward (Oliver28472) provided from the previous post.
Can't believe I didn't run across that when I was searching.

Book says tranny will take 4.49 gal. of 80w-90 gear oil. Fill level is determined by removing the plastic plug on the left side of the tranny near your foots resting place.
Hydraulic fluid is JD 303 or equal. One gal. is close depending on your accessories.

Does anyone know if I can pick up a generic radiator cap from Napa for my 650G or do I need to track down a special one? My radiator cap has started leaking slightly while running, not spraying out just a slight trickle at the pressure relief valve on the cap. I am going to flush the coolant to see if that fixes it, but if it doesn't I think im going to try a new cap first.

 

[TAZ EWG]

Sorry for bring up the past. But has taken me some time to source this link.
My Satoh S-650-G has two issues 1. Leaking exhaust with a ticking noise and 2. Need instructions for my governor, oil required and how to maintain

 

[TAZ EWG]

I just got a regular cap and it wiorks fine

 

[sruman]

I didn't see what the speck pressure rating was for the 650G? Would a 8 lb. work?

 

[rallen1]

My Owners Manual says the system is rated for 10 psi. That being said, I noticed the one on my tractor was only a 7psi, and when it went bad I replaced it with another 7psi since it was available. Seems to be working fine.

I have attached a couple pages on the governer for you.

 

[nosbearatu]

What size Allen wrench do I need to get to take out the hydraulic check plug from the side of the rear end. I need to order one that is big enough and I'm not sure what the size is.

 

[gp69]

Looking for the part number for Satoh SG650 ignition coil? Didn't seem to find in this forum but figured with all this info someone might have an idea.

Thanks E

Hi everyone -
I just picked up my first.
I knew nothing and got a little hoodwinked with missing parts.
Specifically the oil bath air filter, a throttle and a choke cable.

Someone instead of repairing safety items over the years just bypassed them and I wanted to get a new safety starter switch as I make a new wiring harness. I can’t find a replacement part number either and am debating buying a used one.

Any help would be phenomenal.

Thanks!

 

[JDR12B]

found the saftey starter switch and it bad need a source for another one?
gave her a tune up today run s like a top.
thanks for all the Napa part numbers my local dealer had everything in stock except for the condensor.
Does anyone know what the Mazda 1100cc motor was used in by Mazda? and what year was it produced.

Hi! Did you ever find a replacement part for the starter safety switch?
