Oliver 1465 hydraulic pump

Posted by Rick on December 22, 2018, 11:06 am

Looking at a 1465 that is for sale. Guy says it needs both hydraulic pumps. As for as I know there is only one. Is there two pumps or is there 2 different pumps.One for if there is
power steering and one if it does not have power steering.

Super 55 3 point hitch

Posted by Merrill Harrington on December 19, 2018, 6:32 pm

The 3 point hitch can’t be leveled up. I have the right side adjustment turned all the way up and the right side of the blade still digs into the driveway when clearing snow.

Re: Super 55 3 point hitch

Posted by Larry Harsin on December 29, 2018, 7:10 pm, in reply to "Super 55 3 point hitch"

The left & right lift links may not be paired up correctly. Did you mean the right side still digs when it is clear up?

Posted by Merrill Harrington on January 1, 2019, 7:58 pm, in reply to "Re: Super 55 3 point hitch"

No, it’s not that extreme. It’s more like when the right side touches the floor in the shed the left side is 2 or 3 inches off the floor.

Hi Larry could you tell me measurement 2255 rear axle to axle is it wider than 7’8” with wheels off , can’t find any width information. Also still looking for 20” four spoke steering wheel for Oliver 990 called numbers you gave me last time but no good .cheers Mark

Model 1955 cockshutt PTO TROUBLE

Posted by Robin blum on December 13, 2018, 1:41 pm

Hi we rebuilt the pto new seals new clutch plates clutch housing. We have done this several time housing is ually cracked after a few cycles. Hydraulic Oil also always ends up in the transmission. Pro shaft spins and stops but never has enogh power to drive anything. We have replaced the hydraulic pump. Problem started half way though unloading a load of grain. Tractor was running the auger juts fine then is slowed to a vault never worked again. We also replaced the first plate that has the friction pad for the pto brake. WHAT ARE WE MISSING. Thanks Robin Blum.

Posted by Don Herbert on December 12, 2018, 11:18 am

I have an 1800 with oil pressure problems. 30 psi cold and under 20 psi warm at 1000rpm.

Replaced oil pressure relief valves and springs in oil pump and in front of block.

Plastic gauged rod and main journals both with in specs, replaced rod and main bearings.

Found worn governor bushing and replaced.

Have new gauge mounted in block. Next is to rebuild or replace oil pump.

Any other ideas before I do that ? Thanks

Greetings Larry,,,
Got the 770 home,,, started tinkering already. It looks like the right lift cylinder is oozing oil out the top ,,,, I saw a video on how to change the seals,,, not a bad job,, do you know if the loader has a 2 1/4 bore [piston] or 2 3/4,,, the outside diameter of cylinder is about 3 inches,,,, ??? I would like to have the seals when I take it apart,, so it can go right back together,,, Thanks again,,,

1963 550 hydraulic pressure

I am sure this is posted somewhere in the archives, but could not find it. What should the relief pressure be on a 1963 550 hydraulic system? I understand it could be 1500 or 1700 depending on the year? I want to set my remote valve just under the max. Thank you.

880 helical shaft poly bushing

Posted by Paul on December 9, 2018, 9:02 pm

Hi posted about this before but didn't get an answer. I bought a new shaft and bushing however it is too tight. My book says one has to buy the bushing and gear as one piece. I'm wondering if there is an update since I was able to buy it separate. Does anyone have the proper book that shows the installation method?

Re: 880 helical shaft poly bushing

Posted by Arnie on December 10, 2018, 7:31 am, in reply to "880 helical shaft poly bushing "

I have an IT manual for that tractor but it doesn't show a bushing as you mention. I would be very happy to scan a few pages. I assume you are working in the tranny area. Send me an e mail address and any other info that may help. Arnie

I have a 1958 IT manual and an update manual when they went to the helical trans. I suspect there is another update after that. Perhaps your manual covers. I got the bushing from maibach tractor. They found it in their parts book. It wasn't in a package though and was just placed on the shelf where it would've been numerically. I would be glad to see what your manual says.

It fits over the shaft until I press it into the gear. My plan is to lock tight it in the gear and hone it to fit. I was just wondering if any books showed the proper procedure if there is one. Thank you

1953 88 RC oil pressure relief valve

Posted by Darin Gillen on December 7, 2018, 11:51 am

Working on 88 oliver with low oil pressure. Relief valve was stuck open. Sprayed with WD 40 and let it set. Went back and gave it a tap and it moved to the closed position. Now it is stuck shut. At idle I have 25 lbs pressure. Give it some rpm and it max out my gauge. How to remove the plunger without wrecking something.

Re: 1953 88 RC oil pressure relief valve

Posted by arnie on December 8, 2018, 8:58 pm, in reply to "1953 88 RC oil pressure relief valve"

I am trying to remember what they looked like. First I would make certain to have replacement parts before going on. You need to devise a way to get a hold of it. What ever you do be careful not to damage the threads in the block. The plunger is very hard so drilling a hole in it may be tough. If you are able to do so you could use a reverse twist style easy out to grab it. Another thing I have done is to "short circuit" a welding rod to it and maybe you could pull it out. (that's tricky)If you had to tap it in I don't think a magnet will work. Sounds like moisture got in there. I will be interested in knowing what worked for you. Arnie

Re: 1953 88 RC oil pressure relief valve

Posted by arnie on December 9, 2018, 7:24 am, in reply to "Re: 1953 88 RC oil pressure relief valve"

Another thought. Remove the oil pressure line and fittings on the lower right rear side of block. Put a pipe plug in the hole. Save the gauge. Remove pressure relief threaded plug, spring and any shims that may be there. With a helper start engine, slowly increase speed while gently tapping the block in the area of relief valve. Maybe without spring pressure, a little tapping and some appropriate words....The engine vibration and engine oil pressure may help. I would try this first. Arnie

Re: 1953 88 RC oil pressure relief valve

Posted by Larry Harsin on December 11, 2018, 7:54 am, in reply to "1953 88 RC oil pressure relief valve"

Try working with a thread tap to bring that plunger out of the block. Otherwise you might take a piece of wood dowel to try to get it. Larry

Re: 1953 88 RC oil pressure relief valve

Posted by Darin on December 17, 2018, 8:43 am, in reply to "Re: 1953 88 RC oil pressure relief valve"

I got the relief valve plunger out using a small bearing puller. It come out with a few love taps. I wiped it down and cleaned up the area in the block of the motor. Planning to install a new plunger though.

gasket

Posted by b graham on December 6, 2018, 11:16 pm

I am looking to find where I can buy a oil pan gasket for oc4 diesel .they only sale the whole kit

Re: gasket

Posted by arnie on December 7, 2018, 8:48 am, in reply to "gasket"

From what I found they may have used more than one engine. 3 cylinder Hercules. DD130 or GTO130. You will need to know which it is. Look for tags or casting #'s on block. If it is a flat gasket it might be easier to just cut one. Your local Auto parts store can furnish gasket material. Have done that many times in my shop.

55 PTO Clutch

Posted by Carl on December 3, 2018, 9:07 am

The disc on the pto clutch have come out of the grooves/clutch pak they are suppose to be in. There is lots of loose play and I think the hex key that is suppose to lock it in place came loose. The pto will not even go when I engage the pto lever. Do I have to split the tractor to fix this? thanks for your help.

Re: 55 PTO Clutch

1850 axle bearing

Posted by Jeremy on December 2, 2018, 4:25 pm

Hi Larry. I have an 1850 diesel that needs new bearings in the left rear axle. When I pulled the tire and hub off I noticed what seems like plenty of end play up and down and in and out. I pulled the seal and noticed steel shavings behind the seal and one roller on the bearing is in tough shape. I have a book and it says I need to remove the hydraulic housing to do this. What is involved in doing this? I need to pull the pto housing to reseal the pto. Is there any way I can do it from the back since I will have it open anyway. I appreciate any advice you can give for the process to put new bearings in this tractor. The right seal isn’t leaking and I didn’t notice any endplay on the axle when I removed the tire. Should I leave it be or replace the bearings on that side too. I really appreciate your help. Thanks. Jeremy.

Re: 1850 axle bearing

Posted by Larry Harsin on December 11, 2018, 8:07 am, in reply to "1850 axle bearing "

I think if you remove the PTO assembly from the tractor, you will be able to replace the bearings on the axle without having to take the top off. You will have to remove the tap ring that holds the bull gear on. Then you can slide th axle out of the axle housing. Now, if the inner bearing has to be replaced, you will have to remove the axle housing from the tractor. Larry

880 transmission

Posted by Joe Rehmer on December 1, 2018, 2:40 pm

Larry, I've got an Oliver 880 diesel with power booster and helical cut gears. It's a 1960 model (s/n 89703).

I'm having problems with the transmission staying in gear on the low side (1, 2, 4, R1). It wants to jump out and grind the gears (stick stays in place). It works fine in the higher gears. It doesn't matter if the power booster is in direct drive or under drive.

I've had the transmission cover off the the engine out to see what's going on with it. I bought it with this problem. I found the previous owner had too many shims in the front moving the bearings and shift collar too far forward. I corrected that problem, and thoroughly inspected the top (input) shaft, gears, and collar for issues, but all looked good. I had an old Oliver guy look at it and said all looked good. I put it back together and still have the same problem. I'm pretty sure the shift collar isn't staying engaged far enough on the gear for the low range gears.

What can I do to fix this?

Re: 880 transmission

Posted by Arnie on December 2, 2018, 12:31 pm, in reply to "880 transmission "

Without seeing it you may be describing a bent or worn shift fork or the gear it fits into. Also check the dent ball, spring, and indentation the ball fits into. Is it only under load or anytime? Make certain the shaft is not moving forward or backwards. Good luck Arnie

Re: 880 transmission

Posted by Joe Rehmer on December 2, 2018, 7:37 pm, in reply to "Re: 880 transmission "

Arnie, thanks for the insight. To answer your questions, yes I've checked and made sure the detent ball works as it should and the shift fork isn't bent. I need to pull the hydraulic unit to verify exactly what's going on when this occurs. It happens all of the time trying to drive it even under the slightest grade of pulling itself. It acts like the shift collar isn't staying engaged with the gears enough to hold it in gear if that makes sense. It's been awhile since I've messed with it, and I need to tear into it again. I need to verify if the shaft is moving, as I haven't done that yet.

Re: 880 transmission

Posted by Larry Harsin on December 11, 2018, 8:11 am, in reply to "Re: 880 transmission "
