For Sale or Wanted / Re: Track Topaz chassis
« Last post by JJ7488 on April 18, 2018, 08:46:31 PM »
Hi Allan

How hard was it removing the body off the trailer?  How straight does the chassis look?  Any damage?  BTW how’s the project coming along?

In response to Harry’s questions.
1. Repack the bearings by hand just working the grease into the bearing rollers.
2. Certainly try to continue to use the same wheel bearing grease and am guided by the recommendation of the Bearing Shop.
3. Always use rubber bushes from Track. I am aware that this is more expensive than the neoprene option but Track recommends the rubber option as they are softer. If caught short on a trip the bushes can be turned upside down as they only wear on the one side.
4.  Checking wear of magnets is also a must. There have been a number of threads on checking magnets and keeping them in place when replacing drums.
5. All that I can do is a visual check of axles. It is getting into the league of wheel alignment and the need for more gear than I have.
6. Always replace the bearings as a complete set. Bearing and race together.

A good list.
I would add checking the brakes. The drums seem to retain a lot of dust and generally need a good clean out. Alko's instructions are pretty good:

If you have Thetford service doors for the kitchen and storage, I find the screws need a little tighten after each long trip.

Cheers,
Andrew

Pretty well what we do. We just go around checking all the fasteners (nuts & bolts, rivets etc) as well
We use bearing packers and have a press too, which helps when servicing bearings. We just check the grease to show signs of water or metallic bits or grit. Each time we've checked, its all been good. We use a synthetic grease.
Our brakes work even better since we used them for a short while when our tow vehicle lost brakes...bedded them in REALLY well..lol

All good points there Rob!

Some questions here come to mind.....

Do you use a bearing grease repacker or repack the bearings by hand?

What bearing grease is best or doesn't it matter?  I try to match the grease I have at hand with what the Caravan Service people use so if I'm stuck on the road, then greases are compatible, however different service places use different greases.

Do you get spare shock absorber rubbers from Track or elsewhere?  If so where and what sort because I need some spares.

Caravan places also check for wear on the brake magnets and replace them if required and check the brake shoes and adj the brakes.

I have also read somewhere that the axles should be checked for cracking when the hubs are removed and I would be very interested in any ways of detecting slight bends in the axles, as my Topaz does seem to have a significant camber issue on the right hand (battery side) wheel compared to the left hand side (door side).

Cheers!

I've also heard that the bearing races and cups should not be mixed up as they are matching sets.

I think adjusting the brakes has been well defined in a few places, but I have never seen any instructions on how to adjust the hand brake.

Getting a good thread going here with input from those in the know would be most helpful.

Jack up each wheel separately and using the ratchet wheel behind the rubber plug, turn the ratchet with a flat screwdriver if you don't have a brake adjusting tool. Adjust the ratchet spinning the wheel until the shoes grab on the drum. Now back off the ratchet 8 clicks of the ratchet. Should run free. Now lower this side and raise the other and follow the same procedure. Now you can adjust the hand brake cable and all should be sweet

We have had a Tvan or Topaz now for 9 years and have always done our own servicing. However, some manufacturers of caravans ( eg Supeme) now stipulate that you must have your caravan serviced by an accredited caravan repairer or your warranty will be voided. Not sure how they can legally do this but this is what they stipulate.
Track does not do this.
For us to have the Topaz serviced by the Qld Track service agent we haven’t round  trip of 200 km and a final bill of at least $500-$600. Not for us. I can get our Landcruiser serviced by Toyota for a fixed price of $280 for the first 60000 km.
Maybe it is because the vans are becoming more sophisticated and complex that the notion of having them serviced by a qualified caravan service person is becoming more common. Maybe it is a matter of being time poor as well. At my most cynical I would say it about making money!!

So here is a list of what we do in a service
1. Clean the DO 35 hitch with brake cleaner and then lubricate all parts and grease at the grease nipple
2. Remove the jockey wheel, clean out dirt and old grease with brake cleaner and then lubricate.
3.Remove the shock absorbers and. Heck for wear of the rubber bushes. Replace if heavily worn, if not lubricate with rubber grease and refit bushes to shocks. Check the shock absorbers for compression and rebound.
4. Wheel Bearings.
      When we are travelling regularly check the temperature of wheel bearing just by touching to see if they are overheating. Also check for any wheel movement by grabbing the wheel and seeing if there is any movement. If the wheel has movement to me this indicates that the nut holding the wheel bearing is not tight enough. Too tight and bearings can overheat.
      Around every 10000 km or after a hard trip remove the bearings, clean with brake cleaner and check for signs of heat or wear. Dirty grease, scoring of the race or blue discolouration.
      Replace the inside seal.
      Adjust the nut so that tension is right
5. Check for tyre wear patterns
6. Lubricate hinges and door locks.
7. Crawl under the van and inspect the chassis, bushes on the suspension,  wiring and hoses.
8. Check battery.

A lot of what might be called a service is stuff we check as we use it or when we travel. Stuff like plumbing, switches,catches and electrical fittings

The one thing we don’t try to do is wheel alignment.

Others will have a more comprehensive list which will help inform us all.
