I've been using an NLGI grade 2 wheel bearing grease for the front and rear bearings on the Adams.
The rear bearing has always thrown a lot more than the front. The crankshaft doesn't show any fore and aft or up and down motion to suggest they are seriously worn but no doubt they do have a lot of wear.
Today, when cranking the engine I noticed a slight hissing sound that appears to be coming from the rear bearing. The engine is also hard to start. Before I get too crazy, is there a heavier grease available that I can try in the rear greaser to see if that gets rid of the hiss and makes the engine easier to start?
Cheers! |

I am looking for brand names of NLGI 3 greases that I can try in the rear cup. Schaeffers 238 and Lubriplate 130A have come up. I'd be interested if there are others I can check out. They must be NLGI 3.
The data for 130A says it is good up to 170 degrees F. I'm not sure if I should eliminate it on that basis.
I've also wondered if people have made their own concoctions? I've heard of people mixing in bar soap or toilet ring seals to wheel bearing grease to thicken it up.
The idea here is to squeeze more life out of the Adams before it either has to be retired or completely re-built.
What say you? Ernie. I'm lookin' at you. Good idea or bad idea?

This morning I called MotionCanada. They are going to get both Lubriplate 115 and 130A from their distributer. Hopefully I'll have it later this week. I'll give that a go.
My guess is that the leak only became apparent with the new rings and lapped check valve.
Hopefully this will fix my problem.

Motion Canada came back saying I'd have to buy quantities of each in bulk. They would not sell me 1 lb containers. Not a chance.
So the hunt continues.
I am seriously considering taking some NGLI2 and cutting it with toilet seal wax.

Chris,
I understand that you are trying to get some additional use out of the Adams.
However fixing the compression and bearing problem shouldn't have anything to do with it blowing grease out the rear main. The good rings are keeping the compression up top where it belongs. A good rod bearing is just that a good rod bearing.
Since you asked here you go.
Read both posts fully and the links in the messages and use Lubriplate at your own risk.

The strap wrench in the 2nd post is a nice touch but it should ONLY take hand turning force to screw down a grease cup. More than hand torque/turning force indicates a problem or potential problem. Or the wrong grease.
Narrabay was at my shop today and we discussed this. I showed him the can of Lubriplate white tar. It looks just like it did when I stopped using it after almost ruining the engine in my boat.

Thanks Ernie.
As always, your input is helpful. I had already eliminated Lubriplate.

I've been wondering about grease lately because I'm about to rebuild a Blaxland twin with Babbitt bearings to which I'd prefer to use a heavy grease but probably not NLGI 4 grade for the reasons stated in the above discussion and links. I have already bought some Lucas Marine Calcium Sulfonate NLGI 2 as it claims to reject water very well and as the front bearing is directly below and next to the water pump the leakage has already taken a toll on the babbitt and crankshaft from water ingress. Still, I'm not so sure a grade 2 grease is going to be solid enough so I'm looking to find an NLGI 3 grease also as Chris has stated, but trying to find a Grade 3 is near impossible, even Google is letting me down. I thought I might try Lucas Grease X-tra Heavy Duty but is still rated at 2. |

Hang on Putty. My daughter who is a vehicle tech in the military is sending me something. Once I receive it I'll let you know.
WRT Grade 2. Grade 2 is Grade 2. If you need a 3, no Grade 2 will work.
As an interim step, and as a test I mixed some 2 with an amount of toilet seal wax. It seems to help although there is some obvious risk. I figure with the low melting temp of the wax, the probabilty of doing damage is low enough it was worth a try. But like I said, it was an interim step until proper grease arrives.

Thanks Chris, no rush as I have a bit of crankshaft polishing etc to do, I'll be hanging around.

Putty.
The product my daughter ordered for me online arrived today. It is Mobil Unirex N3. Cost-wise it is pretty Gucci stuff in comparison to the NLGI 2 greases out there.
I've loaded it into the rear greaser. The front still has the NLGI 2 grease in it which I might as well use. Tension-wise, as anticipated, I can feel the difference.
I have been told that NLGI 4 greases are difficult to use through greasers. This is not like that. And so it might be a good choice.
I hope to take the boat for a run tomorrow. I'll let you know how it goes.

I put about 2 hours on the Adams this morning. NLGI 3 grease seems to be the ticket. Once I've used up all of the NLGI 2 in the front greaser I'll load it too.
No question the stuff is expensive. Is it worth it? That question remains. My guess is that it is.

Thats Great news Chris, might be finally getting somewhere. I was starting to think about mixing a 2 and a 4 together. I asked at the engineering shop about No3 and was told to check out a bearing shop not far from me for better info, so I did and found out that nlgi 3 and EP 3 are pretty much same thing so googled ep3 and came up with a few results, more than searching for nlgi 4 anyway, I'm thinking you might have nailed it with the Unirex N3 and the specs will be handy to compare but I'll have to see if I can find it or something locally down under.
Cheers. |

Hard grease & other products can be purchased through Opti-Lube Severe Service Lubricants.
Opti-Lube 1646 West Business park Drive Suite B
Orem Utaha 84058, USA
Toll Free: 1-888-326-6789, Local: 801-491-3717
I use the Opti-Lube Lithium Block Grease 1st item on their list under block grease, It was $4.79 a pound back when I purchased it. I think it cost around $6.30 a pound now. Opti-Lube service tech person recommended this type of grease for my application and I have used it on all my 2 stroke engines sense Feb of 2006 with no problems, works great. They will sell it in smaller quantities then what they have listed but I think 10 lbs might have been the smallest. So you may want to get a few of your engine friends to go in with you and split the cost. This grease is a very thick paste so thick it is sold as a block of grease. See link below. I'm not affiliated with Opti-Lube it's just a product I use that works the best for sealing the bearings & lubricating the old flywheel 2 stroke bearings.
https://opti-lube.com/block-grease.html
Just went on their website and it appears they have went up around $3 a pound sense the last time I went on their site. Probably more then most will pay. |
