I might be blind but I'll be darned if I can locate the transmission full level oil plug on my 770 gas. I drained the oil when I bought it 14 years ago and added the prescribed amount. When I checked my Oliver shop maunual I could not find any reference to the oil level plug. I do not own the original owners manual. Do any of you guys know where it is?

Dave
I was wondering where you live in Alberta. If you are near Edmonton I have the manual for the 770 (1960 edition). You can stop in and look at the information in it. By the way the picture in the manual shows the transmission oil level plug on the right hand side of the transmission housing just in front of the disk brake cover.

Another angle on this rear end/trans oil business. After the Oliver/White dealer I was parts manager for closed I went to a "blue" tractor dealership and we were constantly getting this same question as the original MANUALS for 9N 8N etc. called for 90wt,and New holland reccomended the 134 (a high grade "uni" oil). The 90w spec'd in the old manuals WAS NOT GL-5 gear oil, it was what NH's oil supplier called a straight mineral oil, and is about the same viscosity as 50wt motor oil. This oil supplier is the OEM oil supplier for NH, Case/IH and several other OEM's so I'll take their word for it. GL-5's and the old spec 90w might both be 90wt but it's on different scales like degres F, and degrees C on a thermometer.

I have a local lubrication compouner get it for me. He custom mixes lubes for GM assembly lines etc. I'll get a hold of him and se if he can tell you where to obtain it locally for you. The stuff doesn't have the severe sulphur smell of the GL-5 lubes. I'm in SE Michigan.

About 40 miles east of Lansing, Was parts manager for R.E. Peckens. Till he closed in 1993 he was the oldest dealer in Michigan (est. 1896), and had Oliver longer than everybody except Loseys in Springport. Chris the sysop at the Olivergang site can tell you for sure but as I recall they got Oliver in the mid 20's and R.E. got them in the early to mid 30's. I still rember old R.E. whaping his cane on the lunch table and saying "I sold 37 70s in 1937".

You can still get from an MF (Agco) dealer MF1103 oil which is mineral oil for use in the older tractors with combined sumps. Kendall makes a product called Kentran80 which is mineral oil with antirust additives and is very good. The newer light oils like Ford/New Holland 134 will work OK if everything is in good shape but are more prone to leak past worn seals and there may be more gear noise in older units.

Standing behind and looking ahead it is on the right side toward the rear by the axle carrier. I don't know if you have a belt pulley or power booster cause then it takes a little more oil. They hold about 19 quart (american). We used to take a 5 gallon bucket full and dump it in. We figgured the extra quart did not hurt anything. Also if you have an old manual I think they said you 10W-30 or something like that and the 102 082a a additive. When they introduced 80-90 gear oil that was the oil of choice. 16 years of checking them I am going by memory no book to look at,

There is no belt pulley. I will look again in this location. I removed the cover this summer when it seemed to be making too much noise. The level is now halfway up the main input shaft bearing and I am calling that good. There was little wear on the gears and I got only a slight reduction in gear noise after adding 4 litres.

J.

We got into this 770-800 trans lube discussion some time ago when I posed a similar question about the recommened oil type. Some of the later ones used 10w-30 motor oil, but I beleive the early ones used 90w. Something about high speed bearings not getting lubed well enough with 90w caused Oliver to recommend 10w-30.

To each his own but I just don't like the idea of 10 weight oil trying to lube big, heavy gears. I tell you what I used... I put 3 gallons of 85w-90 and 2 gallons of 20w-50 in mine. The gears are quiter and I feel like they are getting better lubrication than with 10 weight oil.

The 770/880 tractors were new when I started in 1960. The reasons we were given for the thin oil was to make sure the sprag clutch in the power booster would work in extreem cold weather conditions. You had to add the additive to this oil then as it came in gallon cans. Then in the next few years this 80/90 gear oil thing started and we never when back to the thin oil. It solved some gear problems that we had before that. I used to have a service bulletin they put out explaining all the advantage to the thin stuff,but we all went back to 80/90. Now go figgure this. The Hydra-Power drives which were released at about this time (62 if I remember correctly)used type A fluid and worked good.

You might want to pick up a copy of the operator's manual. Pretty sure the recommended oil change frequency is a little more often than once every 14 years.

Isn't nice to see so many Oliver fans helping each other out. Good old Ollie opening his mouth with nothing to say! Way to go Ollie!!! You're the best..... . at nothing but buying manuals!!!

Why don't you actually help the guy out or don't you have a manual or better yet.. don't you know? If you don't know the answer, then shut your mouth for once. I really don't think this guy was asking if it's OK to change his trans oil every 14 years. Maybe there's a reason. Help people out and give them the answer they're asking for. If you don't like the concept, then move on!!! Thanks why people come here, for help. Not the first idiot to answer the question and tell them to buy a manual. Cuz we all know how you like to get your name in there first before any one else answers.

No problem with you, just your attitude towards people that are asking for help. Pretty some you wont see anyone asking for help cuz you done chased them all away.


Guess I'll go jump on my 29HP Oliver 88... See ya.

If you could get ollie to email the necessary pages from his manual that would show how to hook up all of your plug wires correctly you might find a whole bunch more horsepower than twenty nine!! Good answer! You're right, we need to help each other more and not be jerks with bad bratitudes.

Resorting to name calling, wow, your mommy is proud of you!

BTW, if you followed the thread, the correct answer is 29 drawbar HP. That's what Oliver published. It was people like you who assumed the answer was in PTO HP on a tractor that didn't come with a PTO!

Most people come here looking for solid information, the kind you can find in the manuals. Those who are too cheap and/or lazy to them buy get no sympathy from me, nor should they. I'm nobodies daddy and I ain't doing their homework for them. However, there are many people who simply aren't aware that the manuals are still available and I've been thanked for pointing that out... "you can give a man a fish or you can teach him how to fish". Those of us who want to learn understand (and recognize) that concept. You, apparently, do not.

I disagree. I think most people get on this forum to get other guys responses. Mostly quick answers to simple questions.

Regardless of your intentions your responses come across as negative, repetitive, and of no help. Even when asking not to respond by saying buy a manual you had to respond with your typical "buy a manual". Why would you do that? I for one would like to consider this site as a source for information in addition to any and all manuals. Some of the guys here have insight and experience that can not be found in the manuals. Sometimes we don't have time to order the manuals and wait for them. Other times it's possible we can't find or don't understand what we are looking for in the manuals. If you really believe people are to cheap or lazy to buy a manual do you think you are helping anyone when you tell them to buy a manual? No, if that where case all you are doing is insulting them. This is not about doing someone else's homework or being their daddy. It a forum to ask questions and get answers. To help someone out. Not to belittle them because they don't have the manual yet or don't understand something in the manual.

Of course there are many questions that can't be answered by referring to the manual. But that, and all the rest of your excuses for not having one, are just that, excuses.

If you prefer to remain ignorant, that's your choice. But don't generalize that choice to others. Most intelligent people want to learn and they realize that knowing where to find the right answer is the key. For subjects covered by the manual, the right answers are there. For other subjects, the people here, most of them anyway, are a fantastic source of information; at least for those of us who realize that their experience and opinions may be different from others and must be weighed as such.

I have the manuals for all the tractors I own so accusing me of makes excuses was uncalled for and rude. As an Engineer I spend a good deal on my time reading technical specifications and guides. I would not be employed if remained ignorant. Accusing me of being ignorant was wrong, insulting and rude. I think what is obvious is that you have no real interest in being friendly. Your knowledge or experience to help anyone is questionable. Considering your attitude it's unlikely that you could be an asset to this forum.

Hey Ollie go back school. Its that time. I can tell you are a smarta$$ kid that dont know $hit!! All you can do is say "buy a Manual" if you cant tell someone an answer(not that you have ever answered a question here)then stay off. All you can do is be the first response with "buy a manual" Now that school is back in session hopefully your stupidity will slow down. An 88 has more that 29 HP. Go get a brain.

I really did not mean to incite any violence. Of course I am aware of the availability of the owner manuals but I have found them in the past to be of little value to the back yard mechanic and thus I have relied on the widely available shop manual. This is the first instance I have found where the shop manual did not measure up to my expectations. Regarding the frequency of oil changes, to put every one at ease the tractor accumulates about 5-10 hours per yer and is used only for the post pounder and the rake. For the record I have run a semi-synthetic 75W-90 oil in all of our tractors for the past 15 years. I removed the top off the rear end this summer looking for the oil level plug and still could not find it. I am eager to get home and check in the locations mentioned. Thanks for the help.

Dave: I went back out ot the garage and it entered my mind that I told you wrong on the location of the check plug. 77 & 88 models are behind the axle carrier 770-880 models are ahead of this. The location had to be moved because of the power tracions hitch now covering this location Sorry about that.

No problem, I won't get home until Thusday night so I will check it then. I was thinking though I might just put a 1" weld-a-let on the top of the case cover and make me a little dip stick. I never have cared for level plugs.

Since I was not thinking and screwed this up for you the first time no problem. Of course you realize that the check plug is for both the final drive and the transmission. The newer Fuller Lightning truck transmissions have sight glasses on the side. Don't know what size thread they are but that might be a neat approach to install one of them and solve the take out the check plug problem.I think we had more problems with leaking hydraulic pump seals and too much oil than not enough oil in the rear ends.

As far as the fish thing goes. My humble opinion is he's asking for a bite, not the whole fish! I know, way over your head and that's pretty far in the clouds.
