Re: M_Boats: What to do if you want to put an M-boat in Salt water fora time.. - rebuilding hubs
Yes. Thanks for the reference, Dave. I don't think I pump up my Bearing Buddies too much but I do get some grease coming out of them and getting here and there. It is likely time to replace the seals. One thing I am completely naive about is rebuilding trailer hubs. I assume bearings, bearing races, and seals are all replaceable at the same time and by an amateur such as myself, but I don't have a clue where to get the parts or how to know what to get. I could image the races may require some special equipment. Can anyone share any experiences or provide any advice? Thanks.

Yep...here's a nice hi-res two-part from "D-Ray's shop": https://www.youtube.com/watch?v=2_9iBXjhaaM And one from BoatUS, slightly lower video quality: https://www.youtube.com/watch?v=jMX3m-uZcr8 Note that in the latter video, he leaves the wheel & tire on the hub, which will actually make driving the old races out and new races in easier for the average DIY person than with the wheel & tire off the hub (as in the D-Ray video).

a double axle trailer for a M17 would be huge overkill. save you money, if you are worried about a double blowout, and get a second spare tire on a mount.
also, i would be very surprised if you trailer doesn't already have bearing buddy's. if there is a zerk in the center of the hub you already have them. if not then you don't.
DON'T overcharge them. DON'T add oil every time you launch or retrieve. you check the charge by pressing on the edge of the bearing buddy cap (the zerk is installed into the cap). if the cap wiggles when you apply pressure you have enough oil. overcharging a bearing buddy will blow the hub seals ... usually the inner seal. will spray everywhere making a mess of the wheel rim, boat hull, etc.

Yep...a large socket that matches the race OD can work well also. As long as one has some experience with this kind of mechanic work in general, and knows not to rush or force too much, it's fine to DIY it. Trailer bearings are generally simpler and easier than car/truck bearings. Both of these guys are careful with their force, and repeat how to work slowly around the race when removing, start the insertion square, etc.. The D-Ray guy even clarifies to use a non-steel hammer on the bearing buddy pieces (the BoatUS guy just uses the steel hammer gently 'enough'...). And, if you don't like some messy work and/or don't have relevant experience...do as Connie (and Dave) recommend! My high school shop teacher had a one-liner that sums up the usual problem of DIY without enough experience: "never tighten it enough when too much will do." cheers, John S.

a double axle trailer for a M17 would be huge overkill. save you money, if you are worried about a double blowout, and get a second spare tire on a mount.
also, i would be very surprised if you trailer doesn't already have bearing buddy's. if there is a zerk in the center of the hub you already have them. if not then you don't.
DON'T overcharge them. DON'T add oil every time you launch or retrieve. you check the charge by pressing on the edge of the bearing buddy cap (the zerk is installed into the cap). if the cap wiggles when you apply pressure you have enough oil. overcharging a bearing buddy will blow the hub seals ... usually the inner seal. will spray everywhere making a mess of the wheel rim, boat hull, etc.

Final PS on this thread, re bearing race tools - many auto parts shops have rental tools, including bearing race tools. In some cases (my local NAPA anyhow) there's just a deposit for the cost of the tool, refunded when you return it without loss or damage - in other words, the 'rental' is free if you don't break it. cheers, John S.

Yep...a large socket that matches the race OD can work well also. As long as one has some experience with this kind of mechanic work in general, and knows not to rush or force too much, it's fine to DIY it. Trailer bearings are generally simpler and easier than car/truck bearings. Both of these guys are careful with their force, and repeat how to work slowly around the race when removing, start the insertion square, etc.. The D-Ray guy even clarifies to use a non-steel hammer on the bearing buddy pieces (the BoatUS guy just uses the steel hammer gently 'enough'...).
And, if you don't like some messy work and/or don't have relevant experience...do as Connie (and Dave) recommend!
My high school shop teacher had a one-liner that sums up the usual problem of DIY without enough experience: "never tighten it enough when too much will do."

When I changed the bearings in my front van wheels I found using a baseball bat end on and tapping the handle of it with a large hammer seated the bearings accurately.

Another reason to take it to the pros is that you really need proper fitting tools to drive out the outer races; and to replace them.
Using a long punch and a big hammer is a very poor way of doing it.
The objective is it to remove the inner races evenly, and you can only do this if you have a tool that just fits the bore and that exerts pressure evenly on the inner races surfaces.
Inserting them again involves also using a proper size tool to make sure that you don't cock the bearing race in its housing and deform it by using a "big" hammer.
You are dealing with precisely machined parts, and they have to be removed and replaced properly if you want to do the job correctly.
I made my own set of tools, but it is not worth the effort for bearing changes every 5 years or so, depending on mileage....
Take it to the pro; keep you hands clean; and let him do the job properly.

Yep...here's a nice hi-res two-part from "D-Ray's shop":
https://www.youtube.com/watch?v=2_9iBXjhaaM
And one from BoatUS, slightly lower video quality: https://www.youtube.com/watch?v=jMX3m-uZcr8
Note that in the latter video, he leaves the wheel & tire on the hub, which will actually make driving the old races out and new races in easier for the average DIY person than with the wheel & tire off the hub (as in the D-Ray video). Otherwise, same basic info. Pretty straightforward, and as Dave said, messy. Don't do it bare-handed like either of these guys, wear some disposable nitrile gloves.
cheers, John S.

Hi David,
Go to YouTube and look up replacing trailer wheel bearings. I found a whole series of videos showing you how it is done.
Connie
Yes. Thanks for the reference, Dave. I don't think I pump up my Bearing Buddies too much but I do get some grease coming out of them and getting here and there. It is likely time to replace the seals. One thing I am completely naive about is rebuilding trailer hubs. I assume bearings, bearing races, and seals are all replaceable at the same time and by an amateur such as myself, but I don't have a clue where to get the parts or how to know what to get. I could image the races may require some special equipment. Can anyone share any experiences or provide any advice? Thanks.
