Evening
I have done a search re maintenace of the tregg hitch and found nothing so:-

As per the heading wondering what shold be done to a tregg hitch besides greasing the grease nipple on the draw bar?

Should the "pin" be greased where it goes thru the poly block?

Should the poly block have any sort of lub where it goes into the "U" bracket on the towbar?

All advice (helpful that is) will be very gratefully recieved.

Effie,

Very little maintenance to worry about. If there is a bit of mud, etc. on and around the poly block, just hose it off.

Lubricating the pin with a spray of silicone, or some other "dry lube" will help with easier insertion and removal of the pin.

Apart from that, just a quick grease of the nipple as you have mentioned and that is all that is required.

I don't own a Treg, but if I did, I reckon I'd be usin' powdered graphite on/in the places you mention...

I have a TREG on the Coromal Camper. It is a devil of a thing to get hitched up when on uneven ground. We have found that a can of WD40 is a must. We give the pin a good spray and then with a bit of judicious wobbling it slips in OK. (!)
I have noticed in the 12 months or so that we have had ours stored outside the rubber block has taken on a crazed appearance. It is massive though and I doubt if it's going to break down. It is probably worthwhile covering it with a bit of plastic when not in use. I should get a grease gun for that nipple though ((!)

All jokes aside, apart from the difficulties mentioned above, I am very happy with the tow-ability. No rattles, no clunks, solid as a rock and the trailer has followed us through creek crossings galore.

Next time you're buy WD.... try Lanox... made by Inox but has Lanolin in it.... very good longevity!

G'day Effie C, yeah! all good advice you have had and I would recommend it but! go easy on the wd40, it is not a lubricant or rust preventitive. Keep everything clean and greased and you'll have trouble free use.
We use a small amount of graphite grease on the block, makes everything fit with that smooth action!

Thanks for all the helpful replys, was wondering if the block is made from the same poly urethane stuff they make the suspension bushes from? They use a special grease on them as normal grease apparently causes the poly urethane to break down over time?

G'day Effie,

Be mindfull of those lubricant sprays and dust. It has a habit of making an abrasive paste if used too liberally, I had to use a bit of emery paper to smooth out some crazing on the pin. My fix for that was a thorough clean, spray and wipe with a cloth. This seems to work OK.

Kind regards

I just grease the nipples on the draw bar.
I never have any trouble hitching up, by myself. I find it very easy on any terrain. The only problem I've had is I squashed the base of the pin when hitting a large shelf when going down Billy Goat's Bluff near Dargo. It's taken a while to wear back to round.
Great hitch.

Twinkles and anyone else who is interested,

The trouble with lining up my hitch with the Coromal Camper (1200KG plus load) is that if I manage to get it within a bull's roar, my assistant has to then wind the jockey wheel up and down to get the appraoch angle just right so that the last few inches of reverse will allow the wobbly block to enter between the limits of the fixed portion. If I am real lucky it does go in and then wifey has to wriggle the draw bar back and forth until she can force the pin in. She does a mighty job most of the time.

If we are on sloping ground and I set the handbrake, the Patrol always rolls about 30-40 MM or so when I take my foot off the brake. I then go around to the back of the vehicle and struggle with the handbrake and try to let the van roll into the hitch. Hopefully I have remembered to remove the chocks on the van wheels so that it can roll in.

Does any one else have a better method?

G'day Kingsley,

I found that when we changed roles (the bride driving and me at the pin) seems to work better - no, not because she is a better driver but because I can give better directions! We now have finnessed this to a simple operation by telling her left and right isn't full lock at the last minute and defining a hand signal for very slow. I can line up the block and have her back it up so it all lines up. I'm bent over at the pin with only a hand showing in in the rear view mirror.

Kind regards

Kingsley,
We have a Coromal with a Treg hitch. We don't have many dramas hooking up because we bought one of them AL-KO single jockey wheels with the ratchet mechanism. Get the CT within a foot of the hitch, then effortlessly ratchet the thing up to the hitch.....

It makes just about every task easier, including levelling on site.

As for lubes, apart from the grease nipple, I apply a sparing amount of grease to the pin. The urethane block looks like it has a brass bush or similar in it.

I back up pretty close to the side of the block. I don't usually have much trouble backing and lining it up. Get out, wind it up to line it up and push it sideways into the slot, drop the pin in. I do it by myself. My camper weighs about 700kg + whatever I have loaded into it. I drive a Hilux, no canopy, and a Bushranger CT with a hard floor. I have a large Alko wind up jockey wheel.

To line up my Treg Hitch better I used an angle grinder to make the bottom of the pin a bit pointier. This way I don't have to get it exactly lined up. My Treg is over 10 year old, has had a thrashing in the bush and on the beach. I have never put anything on the poly block. Just marine grease in the nipple on the drawbar.

One of the good things about the tregg is there is no grease to worry about. Why would you want to put crc or grease or crap of any sort on the hitch?

Brew,

We have found that it helps considerably when having alignment problems (described above)

Hi Beatit,

Nice rig and setup!

I must admit we haven't tried wifey driving and me guiding. And it is true that when she is giving me her signals I mostly do it by instinct. I am not too sure if I trust her to feather foot slowly enough to get on to the pin, but we might give it a try.

The Coromal is quite heavy to move and that is where our problems start on a slope. Our driveway at home is the worst because not only is there a slope but the van is on the flat and the vehicle approaches up a slope. I have to park the Patrol using the handbrake (and it always moves a bit) then hop out and release the brake on the trailer so that we can both heave it into position. I spoke to a bloke in a caravan park with the same hitch on a big double axle off road van and he said he had not had that much of a problem.

We always manage to hitch up in the end.

G'day KingsleyN,

Thanks, it took a few lessons for her to get it righ but it was worth the investment! This approach really pays off when we are bush/beach camping and the jockey is as good as bogged (read absolutely no chance of moving trailer). I now trust her to be able to crawl slowely onto the block as I manouver the block angle and height. The first couple of times were a bit of a worry as there were serious concerns about getting crushed.

Kind regards

Beatit ,you might like to try the system we use when on the sand with the jockey wheel almost imoveable ,we take the hitch out of the reciever and fit to the c/t then reverse up ,this way allows up/down and side to side movement ,seems easier for us as only need to get the hitch a fraction into the reciever for it all to line up.

Not a bad idea either as I guess there is more tolerance in the hitch receiver on the tow bar. I will keep it in mind - but I have succesfully trained the bride (wow, did I really say that?) to reverse with precision.

Kind regards
