The seller tels me the wheels are 15 inches, 5 nuts, and the wheels salesman tels me he needs a part number or the car model and year. The salesman says there are many different wheels models with five holes and 15 inches as a diameter. :(

Anybody ever put his car spare tire on the 2003 Mac trailer? 8)

The bearings job is done at the seller expense. Two new kits, plus two bearings buddies. End of that story. :)

Planing the long ride for next week-end, plus monday and tuesday.

Things go fast....pheeewww.

Thanks for sharing your knowledge and experience. :)

Mike,

You may find some useful info in this thread:

Spare Tire & Lug Info

Good luck with your tow. Wish I was able to tow my boat somewhere.

Cheers,
Jim

Their should be a part # on the rim & see if you can buy it @ Crappie Tire , hold on I have it
part # 343901 this is for the tire & rim that I bought from Dowsar Marine
rim is a
LRC Sport Trail TL , 15X6.00 , 5/4.5 , 8spk. Wht WS 002
Tire is a
ST225/75D15
PS See if you can buy the rim with tire already mounted & save on tire installation !

We work with caravan repairers on a weekly basis, you would be surprised how often brand new professionally installed wheel bearings fail, on all our trailers/campers we normally travel with a spare set of bearings, a bearing repacker and grease gun and have a replacement hub with bearings and spare wheel already attached, this gets stored on the drawbar, I haven't mounted the spare hub and wheel to our Mac trailer yet, only got the boat a little while ago. Before I get flamed about Bearing Buddies the above is current experience, our Mac trailer is the first trailer that we have had that has the oil filled bearing lubrication, the second axle is a traditional grease job.

If you don't know about a bearing repacker they look like this Image
after removing the bearing clean off the old grease, put it inside the middle of the repacker, attach grease gun, pump until new grease comes out of bearing without blockage.

For those that think I am paranoid, I have been caught before with bearings that went thermal and damage the hub beyond repair 90 minutes from the closest town, when I first started to repack bearings I found it a hassle, now I can repack a set of bearings in no time, it also allows me to check the condition of the bearings visually.

Hey Glenn,

Where can you get a repacker set up like that?

I first saw a packer in use at one of our customers, he is a caravan repairer and was doing a service on a caravan, having begrudginly done a bearing repack by hand a couple of weeks earlier I knew I had to get one. The worst part is getting the suckers off if they havn't been done for a while and the old grease has clotted a bit.

The company I bought mine from about 14 years ago is long gone, the old guy retired, I'm in Australia but the pic that I posted is from http://toolmonger.com/2008/02/25/pack-y ... -your-bags they have a link to http://www.lislecorp.com/tool_detail.cfm?detail=1238 it has a Suggested Retail: $ 9.95 they are located at Clarinda, IA .. I think that's in the US.

I'm sure there are many more suppliers. In Australia I have seen one in Supercheap Auto Parts.

I always carry a spare wheel, wheel nut brace/wrench (usually a different size to the car), spare set of bearings, water-resistant bearing grease plus grease gun and of course something to lift the trailer to change the wheel......called a jack in the UK but this seems to cause the the North Americans to snigger! And a decent tool kit so I can tackle a bearing change if I need to. Never had to yet in over 15 years of trailer boating.

I also use a tie-down strap across the cockpit and right around under the trailer and another across the bow and under the trailer behind the pullpit mountings aswell as the bottle screw between the trailer and the winch hook loop.

You could return the favor - by passing on info about some of the places you go - and how it worked out... A lot of us have our stories about our local sites - and where we go... there are just so many choices!!!!

When and where to plan on sailing when you get home? :>

good luck!!!!!!!


I said I would, so I do gladly and thankfully :) .

Long story. The trip going was fine, except for the last 30 km stretch. Google, which was otherwise fantastik, as much for its time estimates as for the exact location, sent me to the wrong lake. :evil: It sent me along the Erie lake to Essex, to the Deerbrooke Marina that nobody knows of there, instead of the Sainte-Claire lake, at Belle River where tha marina actually is. I guess this is because the Deerbrooke Marina wasn't enough of a paying add....

The day after, I encountered problems of the nature of a «7 round to 5 pins» adapter for the pick-up to the trailer electrical cord. :( A local VR dealer from Belle River made up one for me. :)

And finally, the marine notary from Montreal got mixed up in the wire transfer of the money, so instead of leaving à 10:30 AM, I left at 15:30. :evil:

Passed Toronto on the 401, at 7 :30 P.M. on the cruise control, at 92 km/hr, the legs crossed, in the third line (third of 9 (not a typing mistake)), a real pleasant piece of cake ride, all the way through. You talk about a highway. (See in Wikipedia: they say it is the largest and the busiest in the world. I believe so...) The sun was setting. Flowing in a sea of red lights while a sea of white lights was coming in, on the left side. That 401 is an engineering marvel. And Toronto is a bran new city. Something to see. 8)

The rest was a piece of cake, except for the 40 (Metropolitan boulevard) the overhead three laanes highway crossing Montreal, which was a little too cramped and too fast for me. Quite stressful, but no incident whasoever.

The boat is now in a hole that was blown for it in the snowbank. :)

I would like to make a door of the same plexiglass or lexan as the windows. Anybody knows of the color «bronze 2404 ?» that I should look for? :?:

Your help was a real factor in that succesful journey...Thank's everybody. :)

Mike

P.S The actual consumption increase from the rented 2009 GM Sierra alone going at 92 km/hr, to the ride back towing the boat at the same speed ,was +45 %. Could prove handy for those planning a long tow to Florida and a winter sail in the Bahamas.......

I spent 2yrs as an instructor at Ft Belvior, Va. US Army Engineers school back in the 70's. I recall a retired Colonel instructor that was adamant about proper torque procedures for critical bearing surfaces in our turbine generators. The Military procedure called for torque once and never retorque to check. If you need to check then unbolt the nut to zero torque and retorque.

I questioned the reasoning and was told retorqing was not the same as the first torque reading. He explained the tail rotor assembly on Huey helicopters would work loose due to vibration. Retorqing a nut that was in fact still tight and torqued to spec actually increased the load on the thread and may cause metal fatigue due to over retorqing. Apparently some of the tail rotors failed due to retorq stress induce metal fatigue.

There is no argument that the trailer bearings loads are near their maximum weight limits and frequently run hot if the bearings are not maintained, lubricated and set to proper clearances.

I recall there were some reports of the lugs failing during transport. So the operative question for the mechanical engineers is which torque procedure is safe and accurate. Torque and retorque to check or unbolt and retorque once. Or does either method matter. Bottom line check the lugs and bearing temperature.
