That’s it! We need zerq fittings! Force in the new, squeeze out the old. Yeah. That’s what we did before these here fandangled ‘sealed’ bearings.

I have never heard of such a thing. We always packed them beyond where they couldnt hold any more, to ensure even dispersion and flushing of foreign material. Hell, I paid dearly for a tool thats pnuematic, to assist in doing so. When time is money, packing bearings is expensive.

Well, now you have heard of it. Packing too much grease in serves no beneficial purpose and is detrimental beyond a certain point depending on bearing type. This is one of those bearing types.

Are you aware too much grease in the bearings causes the balls to skate and wear flat spots in them and the races?

I'm going to see how long I can run these with the water proof grease. I don't recall ever seeing petroleum jelly being used in bearings that are exposed to the elements. I'll check the current bearings in a few weeks or sooner if they fail. I'm sure it's going to get wet with rain soon. If it's not raining here it has either stopped raining or it will begin soon. I open the outer shell weekly to check for water intrusion. So far I haven't had any. I still need to figure out solutions for the trolly handle and power switch. Both are needed to have quick access. I have to trolly this thing through a security screening and about a half mile trollying to reach my work location.

I used to work on a ranch and some of the equipment had sealed bearings. The bearings were in places that in order to change them out would require total teardown. We used to periodically grease those bearings using hypodermic needles filled with waterproof grease. After greasing we would cover the injection hole with rtv silicone.

I just got an over heat warning from euc world and I think my fan is dead but I still need to get home. What is a safe max temperature to limp home at?

I think the msp/ rs' overheat in the upper 70's C. 70 to 75C  would be the limit to get home. Gotway has put two ventalation holes in the outer shell on the right side of the rs. Get moving with minimal loading to get a little air circulation in the controller cavity.

Ok that's good. The temp alarm was set to 60C so I made it back without going over that

Meh, i dont find it applies to this scenario or most applications outside of extreme duty. Of course you can put too much grease in. When it makes a total mess and slings everywhere, or when you keep forcing grease in until it creates pressure on boots or seals. Of course you can keep pushing grease in while a bearing is sealed and wreck seals or create pressure. I dont see how any of this applies when you pack a non sealed bearing while its NOT in the machine. Pack it wipe it, install it. Ultra sound testing and marketing of additives i see. Maybe theres a shred of validity to the argument, but I dont think splitting hairs here is even remotely an excuse why an improper design is failing in the euc bearing world. Honestly, how much pressure and speed do these puny euc's handle? I seriosuly doubt the friction of a thick grease is elevating temps. If it is so precise, why arent we being told what exact grease to use. Do we beliece the chinese are bothering to use it either? Under greasing bearings is causing rust and friction. "over greasing" a bearing is forcing foreign dirt and rust out while replacing with clean. I fail to see how 'overpacking' a bearing is really even overpacking, when you allow the excess to be forced out prior to instal, and wipe clean. Leaving a mess DOES attract dirt and also collects in areas it shouldnt. Excess grease outside of movement area , can also harden. I use the word 'grease' in a very general term, as theres TONS of varieties. I wonder what variety is coming stock with the new wheels?

Vaseline. That's probably why the failure rate is where it's at. My wife had a Chevrolet Tahoe 8 years ago it was a 2002 model year. If I recall the front wheel bearings were similar to the ones used on these hollow bore motors. I can't remember the exact size. They were a bit pricey but I changed a bad one at about 140,000 miles. I'm sure they weren't packed with vaseline.

The marine grease should work fine, far better than Vasoline, just perhaps not so much of it.
