1650 Diesel Starting Problem

IP: 99.23.106.55 Posted on July 31, 2012 at 03:32:12 PM by Bill

Per your instructions July 5 I found the timing marks on the fuel injector pump. To set I understand the #1 cylinder is to be on compression. Is this true? I'm assuming the #1 cylinder is the first at the front of the engine? How can I best tell if the #1 cylinder is on compression. Been told to watch for fuel at the injector line. When fuel is seen the cylinder is compressed. If this is true, I've done it and still won't start. Can not find anyone in the area (Waller Texas) who can help me. I really appreciate your help.

When you are watching the valve rocker arms to find #1 top dead center, you watch the rockers on #6 cylinder. When the exhaust closes and the intake rocker just starts to move on #6, you will be at top dead center #1 cylinder. Larry

Swear a lot first!!! Take a lot of coffee breaks!!! Then, use one cotter pin to go through both of the connector pins on one side of the connector. This makes it so that the pins in the connector won't spin and wear off the cotters. Larry

550 Piston & Sleeve replacement

IP: 75.60.194.48 Posted on July 22, 2012 at 06:10:32 PM by Greg

I installed new piston, ring and sleeve kits along with standard rod bearings. After the installation with the bearing caps just snugged tight, not torqued, we could not turn the crank shaft using a breaker bar on the front pulley bolt. From here, we put the old bearings back in and still could not turn the crank. Next we remove the two inter pistons, and we were able to turn the crank by hand. By the way the tractor was out of gear. This would suggest to me that the rings are tight in the sleeves. Correct? Now for the real question. The plan was to tow the tractor around and allow the rings to wear in some. When we tried to tow the tractor, however, it locked up as soon as it was put in gear, and this was with just two pistons installed in the engine. What would cause the tractor to lock up this? I have done nothing to the rear end.

I'm wondering if you have the rods put in correctly. Those are off-set rods. You should be able to have that engine altogether and the bearings all torqued up and be able to turn the engine with a breaker bar. Check out those rods and see what you have. Larry

Loaders for Super 55

One day I would like to put a loader on my Super 55 I am restoring and looking for a period correct loader. Mine is a 1955. I have a brochure for a Wagner WM 4 loader for an Oliver, and never see one on the internet for sale. Are they much different than the WM 4 loader for a Ford 8N or 9n? I see tons of those. Are there any other loaders that are correct for that year that you know of.

1650 DEISEL

IP: 75.108.81.28 Posted on July 18, 2012 at 10:56:44 PM by KIM

I wrote about this problem with my tractor dying out while mowing and the problems has gotten worse. I have check all the fuel lines and blew out with air hose and replaced the filters. The fuel has good flow all the way to the Injection Pump. Check the throttle cable and all is OK. The problem with the tractor dying still exist but has gotten worse. I will start it and now it will only run for about 10 seconds then dies. I can wait about one minute and it will start back up but will soon die again. Are there any issues you may know of with the Injection Pump I may need to check. The tractor runs smooth and there is no missing? I have replaced this Injection Pump 3 years ago and find it hard to believe it is worn out? I also checked the Fuel Pump and it is pumping fuel just fine. My 1650 Diesel is starting to loss power then dies after it warms up while mowing today. I shut it off waited a minute then re-started it and ran fine for a few more minutes of mowing but did the same over again Seems to be getting worse.

880 Wiring

IP: 209.112.238.202 Posted on July 18, 2012 at 01:34:45 AM by Corky Marshall

I'm in the process of rewiring my 880 with one of Korves' harnesses. My 880 has the the original generator with the power steering pump and is still positive ground. There is a resistor wired in that was obviously not factory. One wire runs from the resistor to the coil and from that same terminal back to the ignition switch. The other pole has a wire back to the ignition also, on a different terminal. Can you make a guess as to why that resistor should be there? I was told that maybe there should be a coil with built in resistance. The service manual does give any specs that I could see about the coil. Also, I need a new light switch. Do you have a source for one.

1800 gas loading up and no power

IP: 64.196.46.198 Posted on July 11, 2012 at 06:30:40 PM by Bryan McCaskey

I have an 1800 that had been in storage 2 years. prior to that it had been changed to 12 volts, had a new cap, rotor, points, condenser. The tractor ran great, now it loads up and lacks power. The fuel has been drained and replaced, plugs checked. it seem that when cool it runs better than after 20 min. Thought the coil may have problems since it is very hot mounted to the block. Any ideas which way to go?

IP: 75.104.160.36 Posted on July 11, 2012 at 08:28:22 PM by Larry Harsin

There isn't any specs on the exhaust. You have to use your own judgement. If the seats have been ground very deep, I'd replace them. Larry

Re(1): Oliver 1650 Head

IP: 209.50.28.51 Posted on July 11, 2012 at 10:45:30 PM by B A Star

With the cylinder head upside down on the work bench: the intake valve must be between .014" min to .029" Max above the head surface. Exhaust must be between .026" to .041" above the head surface. The closer to he higher numbers the better it will start. Should your valves be below the numbers you will have to replace the valves and/or the valve seats. Any numnbers below the min will cause hard starting and loss of power. The valves are a majority of the head surface, thus if the valves are below the surface the compression raito is low. These numbers come from Serivce Bulletin # GB-10-106 dated 8-8-77.

Super 77 diesel

IP: 66.103.177.220 Posted on July 9, 2012 at 03:33:51 PM by Bob Elliott

Larry I have two questions, I have a super 77 diesel that blows water out the radiator almost immediately when started, way before it can be hot enough to boil, I replace the headgasket and nothing changed, there is no water in the crankcase. What would you suggest I check next? The other problem is when walking along side the tractor you can hear a clicking noise as if a wheel is loose, but it isn't, it is the left rear wheel, is there a wheel bearing on the outside edge of the axle housing?

Re(1): Super 77 diesel

IP: 75.104.160.36 Posted on July 11, 2012 at 08:26:28 PM by Larry Harsin

I don't know what you are going to find. It has to be getting compression into the water jacket somewhere. It could have a cracked cylinder head. It seems like you should be getting coolant into your oil. If it can go one way, it should be able to go the other way, too. I believe I'd take it off again and have the head pressure tested. 2nd Question: Yes. It could be a bad wheel bearing. It could be an outer one or an inner one. Larry

Power Booster

IP: 166.182.3.251 Posted on July 6, 2012 at 09:57:19 AM by ollie

I am working on a 770 Power Booster. My manual says to check the sprague clutch by installing the sprague and the gear on the input shaft, the hold the gear firm and the sprague clutch will only turn one way by hand. Mine does this correct IF you come to a complete stop with the gear and then try to rotate it the other direction. If you change directions without stopping, the sprague does not always "catch". Is this ok, or does the sprague clutch need replaced? Also, had a question on a crankshaft dowel pin. One of the pins is loose in the crank and I can pull it out by hand. It looks like someone made the dowel pin from a cut down bolt? Can I just put some lock-tite on this and be ok? Guy at machine shop suggested that, but thought I would get a second opinion.

My 1650 just had the same problem - it was the lift pump (fuel pump - on the right side of the 1650 engine) that had a crack in the diaphragm and was allowing diesel into the crankcase. Loosen the bolts on the lift pump and if there is diesel that drips out that for sure is the problem. I ordered a new one from Korves Oliver, installed it, changed the oil and the problem was solved.

If the tractor has transfer pump, it could be leaking through the diaphragm. Otherwise, the leakage is probably in the seals for the injection pump drive shaft. Larry
