I just looked on mine Timm, and there is no model number or anything on it that identifies it.

Just SHELBY

If it helps identify the model, the metal tube that houses the jack (just the black part) measures 21 inches

Maybe call Shelby and get some help?

I did call Shelby Industries........truly awsome customer service. They are sending me some new pins to use on my jack being that I broke the roll pins in my jack. They aren't using roll pins anymore and are sending me a new solid type that they are using.

That's encouraging - and good to know... I used a nail that I cut to the 'right' length and it certainly seems to work.
Curious - how did you identify the model # of the jack, or is there only one?? Also, how did you contact them - phone, fax or e-mail??
Now we'll see if they respond to Canadian enquiries...

I gather from this that the US trailer is supplied with a jack specifically for the trailer.

This is interesting because as far as I know the UK trailer is not supplied with a jack. The standard UK trailer used to be a single axle job (choice of 1500kg or 1800kg rated axle) made by West Mersea trailers although they have gone out of business - I know, I know.... if they can't be bothered to supply a jack they don't deserve to be in business!

Anyway, are there any UK owners able to comment? What jack do you use? If you were to have a flat do you think you would be able to get the thing jacked up? The bottom of the axle is about 8 inches off the ground with the tyre inflated. Take away about 3 inches of air in the tyre and you are left with 5 inches to get the jack under. Any thoughts?

I had to replace my trailer jack wheel housing (the part with the wheel that slids onto the bottom of the jack) a few weeks ago and found out that that size is no longer being made. Luckly I live close to Macgregor and Bill got me an old size one. His part guy also said that this size is being replaced.

I pretty much had to describe to them what it looked like and about how much it handled. I too lost my caster and had to make do with something bigger but it works. Here is their website http://www.shelbyindustries.com/

Thanx - I will call them and try..
For the info. of anyone else around here (B.C. & PNW) our friendly local Mac dealer (& wheeler) Gerry Berg can usually get the parts - he's a great resource for us.....

Mike;
i think the "jack" being referred to is the front wheel machanism that raises and lowers the tongue, not a jack per se as needed to change a tire.

why is the front of the trailer supported on a wheel. ? could anyone reasonably pull the boat and trailer around even on smooth concrete with that wheel. ? :? looks like a sure way to bend or break something. the off-axis caster also puts a torque on the jack and frame. a large dished plate would be more useful, wouldn't bury itself in grass, or on hot soft pavement so easily. The off-axis caster of the wheel on my X had at some time previous been somewhat collapsed and deformed, so i bought a much stronger replacement from WM. :idea: their caster and wheel had a larger cup than the trailer's jack post, so i cut the cylinder part of the cup off of the original wheel for a shim/liner/spacer and jammed it into the new WM caster's cup, with a bit of drilling to line up holes and now it fits fine. :wink: :arrow: still i'd rather have a large flat steel plate with rolled up edges for the tongue jack. could probably slide over any surface as well as the wheel could roll.

Im not the weakest guy in the world but Im not Joe Weider eidder.

I usually pull the boat onto the trailer hitch with the front wheel by myself, on asphalt

Its useful to me at least

YMMV, especially if you have magnets on your fuel line.

Maybe the wheel should permit a little side-to-side movement to align the tongue over the hitch ball, but even that slight movement takes a mighty effort for my trailer. It might depend partly on the type of tarmac, partly whether the trailer tires have sunken slightly.

Besides, I've become pretty good at lining up the ball exactly under the tongue. My technique is to back into alignment from an angle, sorta required by my parking slot anyhow, so the truck's front wheels are naturally turning while backing. As I approach within 8 feet or so, I walk back to judge the remaining distance and angle. Then I correct the steering angle and back another 2 feet or so. It requires four trips from steering wheel back to view the hitch, but it generally permits me to crank the tongue directly down onto the hitch ball.

I am on grass. :o so i just back the van's hitch ball under the tongue, and lower away. but i can't imagine dragging the boat to the ball, even on smooth pavement. :P ( maybe wagging it a bit to line it up finally.) 'guess i'm lazy, too

Ah. We call that thing the "jockey wheel". A "jack" is used to raise the trailer - either scissor jack, trolley jack or bottle jack.

My parking manoeuvre at home involves unhitching and swinging the trailer manually through ninety degrees. The jockey wheel traverses the grass lawn in the process, so I have some old plywood sheets handy. The wheel runs easily over the boards and the tarmac drive.

ok, i'll let you keep your nose wheels since so many of you like them. :wink:
and as soon as i changed mine to a plate i would need to roll it instead.
:idea: since the wheel is interchangable, might make a plate and try it while keeping the wheel.
