Oliver Chain Coupler installation

[@133dave133]

I've never seen a single cotter pin bridge two links before on a chain. It made me scratch my head a little.

[@ThatOliverGuyChris]

It keeps the pins from spinning in their holes, which wears them out quicker. I should have mentionedthat in the video.

[@petepeeff5807]

Yes, if you use 4 small cotter pins the chain link pins will rotate and wear the cotter pins out.The chain will exit the tractor at an inappropriate moment (like when it's 100 degrees and you really want to get some hay raked) and more often than not tear off you're brand new ground speed gauge drive. So move the engine forward and use the long cotter pin and don't cut corners. 😀 Dont ask how I know. 🙄

Thank you for the video! Dad has a 1800 C with hydra power that started making noise. We assumed its a bearing inside the hydra power, but have just parked it until we get around to working on it. Now I want to look at this chain to check on its condition. I have never had any issues with this chain in the past on any in our neighborhood, but there is always a first.

[@bigun447]

I always found it amazing when the weather was 70 degrees and it broke under a shade tree the customer usually could replace it themselves. Zero degrees, or 100 degrees, or buried in mud, or covered in manure, we always made a service call. I used to stock one of that number in a drawer of my truck toolbox. It was amazing at how many ones would find that was totally worn out but still going. You brought back many memories and I remembered that part number before you showed the box. BTW, that was cheating doing it without the fuel tank and everything in place. Tee Hee

[@ThatOliverGuyChris]

I had put one in a customer's 1755, then a month or so later it threw it. I stood in the manure of a dairy feed lot to put it back on, to find out they had taken it to someone else for a clutch job after I had worked on it. The sprockets were NOT lined up. Always nice cleaning up someone else's mess. Lol

@@ThatOliverGuyChris Bet all of us old wrench twisters could colaborate on a book about memorable crappy repair jobs in even crappier places. One of my favorites was when a customer would be banging on your door at 6:00 a.m. on a Sunday morning wanting you to go into the dealership to get some part and then you found out it broke last Wednesday. Can you say their next repair job had a little higher labor rate?

@@ThatOliverGuyChris Then there is the opposite side, when you have a Good customer who was faithful to you over the years go out in his machine shed and hang himself because some big farming operation rented a major part of his ground out from under him. That one made us very sad because we would have gladly have helped him sell his equipment with no commission if we did not have any idea where he could have picked up some more ground. We always had the policy that if a farmer passed away and he had some small debts on our books we would send the widow a statement for $0.00. So you wrote off a couple hundred on parts, somehow the word would get around (not from us) and it would come back in the family and friends stopping in when they needed a new plow or something else.

Unless I'm remembering wrong, didn't Oliver sell a "chain coupler grease"? I've had good luck keeping them schmeared with grease. Sometimes when they would let loose the chain could whack an oil line fitting on the over/under.

[@ThatOliverGuyChris]

It's tough on a fwa. The only trick I know there is to take the motor mount bolts out and slide the engine forward an inch or so. Then get the chain on the sprockets. With it forward that little bit there's enough room to get the pins in from the rear with the connecting link on them. I put the small cotter pins in, bend them over, then slide the link on, then I can put all that in the chain. Put the front link on and slide the long cotter pin in and bend the bends on that, slide the engine back and you're done.

Mr Losey, I am working on my 1800 B model. I had a hyd leak into the rear end. I had tore it apart last spring to replace the hyd pump. I found out that there weren't any new pumps for that vintage. I put a used pump in. That all went well. A few hours of usage and I couldn't keep the hyd reservoir full. I tore it apart now after the first of the year. I am updating the system. I am trying to put the pto drive shaft back in. It seems to go in fine till it gets to the front of the case, then it hits something and won't go any farther. It has a cab on it so I can't work on it from the side. Do you have any ideas for me to try? Thank you.

[@ThatOliverGuyChris]

Are your couplers lined up on the front of the transmission? Sometimes the splines don't line up on either the PTO or the gear that drives the hydraulic unit, and it takes some turning of the shaft and retrying to get it to go. Also, make sure the shaft is straight by rolling in on a flat surface. Beyond that, I don't have much help. For future reference, you don't have to pull that long shaft to take the hydraulic unit off. Maybe there was something else you had to work on at the same time..

[@terenceblanchette9059]

@@ThatOliverGuyChris Thank you for the ideas. I thought of the shaft not being straight. Haven't really taken the time to inspect it. The alignment of the splines is not my problem I don't feel, but I will carefully check on that. I removed the drive shaft to update the pump drive as long as I had it all apart. I have a suspension that the shaft is warped a little. Again thank you for your thoughts.

[@tpfromcentralpa1692]

As an IH and Deere guy, I was always amazed at why they decided to go with a chain coupler. What was the reason they stuck with it for so long?

[@ThatOliverGuyChris]

The initial idea was it allowed for a larger range of tolerances in machining the frames. It worked well enough, but once they started getting over 100 hp, they did come up with something better.

[@mischef18]

Great video bro.

[@stampingdieguy147]

Another greatly helpful video, thank you! My Dad is gone so I'll pose this question for you to answer- I've got an 1800B like Dad had. I looked in the operators manual for lubrication of the chain coupler and found nothing. Due to dust and such I know that you want to run some chains dry. Does this apply to the chain coupler or should it be oiled?

[@ThatOliverGuyChris]

I've always left them dry. I 've heard of some guys oiling them. There's a product called Fluid Film that would be great for it. It sticks really well and would be less likely to fling all over.

[@bustersmith5569]

@@ThatOliverGuyChris fluid film ? Thought that was for undercoating ? My 1750 gas just has a light coating of oil..

[@ThatOliverGuyChris]

Fluid film is made with lanolin, so it does lubricate. It is very sticky, which makes for good undercoating, but also works good on chains because it doesn't fling off and make as much of a mess as regular oil.

[@xade7863]

My 1755 the chain coupler isn’t align and about once every 6 months the cotter pins break or end up coming out can I leave the chain on and align it using the bolt under the tractor without loosening the motor mount bolts?

[@ThatOliverGuyChris]

Yes. If you have the correct motor bolts, the side to side should be right. Adjust the bolt in the frame for the up and down, but there's no need to loosen the engine bolts.

[@stephenfonder7409]

Hey Chris, I've got a big expensive question for you. The other night after finishing up plowing with our TG 210 and I was letting it idle to cool down the engine started to make a ticking/ vibrating noise. The oil pressure was just fine and water temp. We had the NH macanic come look at it. He said it could possibly be a scored piston, but would have to take it to the shop to do a compression test. Also as a side note after the first oil change on it after buying it we did an oil test on it and a high level of silica was found in the oil. This told us that a air intake hose clamp must be loose. Which sure enough we found. It has always used more oil then it should. I am thinking this could have caused some damage to the engine. The last oil tests we have taken have shown nothing abnormal in the oil. Any thoughts about what could be wrong. Also it has a Cummings 505 in it.

[@ThatOliverGuyChris]

Boy, that's a tough one. A compression check is a good place to start. Does that vent the crankcase to atmosphere or back into the intake? Just wondering if the amount of blow by increased. That would be a sign of piston damage. You could run it without the oil fill cap on and see if there's excessive crankcase pressure. Does it act like it is missing at all? A bad injector can make some funky noises too. If you have a infrared thermometer, point it at each port on the exhaust manifold near the head. There can be some variation, but they're typically 10-20 degrees of each other. That can help narrow it down to which cylinder is acting up.

[@stephenfonder7409]

@@ThatOliverGuyChris The macanic took off the oil fill cover and checked for blow by like you said but didn't think that it was excessive. He also thought about an injector as well, or possibly a valve. Paul and I have been worried that possibly the cross hatch pattern on the cylinder walls got taken off when the dust got in the engine. Maybe this had nothing to do with the noise at all, but could still be the reason for the high oil consumption. The macanic told me earlier this fall that this engine is supposed to burn 4 quarts of oil for every 200 gallons of diesel burnt when working it hard. I know it burns more than that though. Do you know what your 6125 is supposed to burn? It is a smaller engine but I am curious if the Cummins burn more then other engines. Thanks for your insights Chris!

[@ThatOliverGuyChris]

I never have to add oil to my 5.9 Cummins. My combine has the 505 and it does use some oil, but not that much. I think I put 8 quarts total in it all of harvest, which was over 100 hours. I thought it was odd at the end of harvest last year that it wasn't using any, then it started growing oil. It didn't smell like diesel, so I resealed the hydraulic pump and problem solved, it's back to using oil.

[@ThatOliverGuyChris]

For what it's worth, loosing the cross hatch would lower compression and cause oil consumption, but I don't see where it would cause a noise out of the ordinary.
