Hi folks, what is the wheel bearing size of the Sprite tourer sp. I want to aquire one to be safe. Alko Montana told me, they do not know the correct size. Please assist.

Surely any of the major dealerships should be able to supply them. I got a spare when I had then replaced about a year ago.

Hi there, any reason why you'd want to carry a spare bearing around? 

1. My SC is now 7 years old, has done a considerable mileage over various terrain and the wheel bearings are fine ( I do check wheel play from time to time). I find that the SP/SC range of Sprite caravans have a good size bearing in there (I checked mine to see during the first service) and I will put this down to the fact that these caravans are seen as "Off-Roaders" so the bearings can cope with fairly adverse conditions

2. To carry an unmounted bearing, especially the taper bearings used by these caravans means that special treatment is called for - NO vibration when you transport it, careful packaging to ensure no dirt enters the package, and no exposure to sunlight  as far as the grease is concerned. So many times a damaged bearing is mounted and this will only lead to even more problems. 

3. To mount a taper roller bearing, not only the cone, but also the cup, needs to be replaced. Will you be able to do this as a road side exercise? NO WAY!!

4. I will honestly advise a mere checking of wheel play before you go, and that's it. I am also very much against the continuous repacking etc. of wheel bearings advocated by just about all "service centers". Wheel bearings, -when properly mounted and lubricated - last a VERY long time!

When I bought my Bushlapa I also added to the extras a bearing kit. Nicely secured in a container with all you need. Including grease. In the last 4 years It was not neccessary to use it. But, have come across guys in Namibia and Richtersveld who wished they had a kit. Definitely a good idea to have a bearing kit for when you need.

Bought my previous caravan - second hand Bushbaby - of about 8 years vintage with a bearing kit included. Never used this kit. Sold the 'van after 5 years, and checked the "new" bearing at that stage (still beautifully wrapped in the original FAG package), and found vibration lines already having ruined the bearing - cup as well as cone. But ja, every man to his own taste and desires ....

Hi, thank you for your valuable advice. Let me indicate that i first bought my caravan the expo in 2010 sold it in 2014 without changing or servicing the wheel bearings. Bought the Regal in 2014 and  checked the bearings. They were found to be in order and original. Traded it during September 2019 for the SP.  Reading from other members i found it better to have a spare unit more so that i will be doing gravel roads. But given the advice i will depend on servicing the van and checking wheel ply regularly. Also a bonus is i have what is called Caravan and tow ball weight scale which assist me not to load my van more than the required 1370kg. So my van is always within the required limit as a result of this instrument i got internationally. 

Regards

I am an old ski-boater. Have had to change a wheel bearing at the side of the road in Mozambique before today. I admit that I am paranoid about wheel bearings. I believe that if I carry a spare I’ll probably ever need it. It’s called insurance..

Nico baie dankie vir die deel van jou kundigheid. Ek is seker min van ons het al gedink aan die vibrasie skade terwyl mens met gerusde hart 'n spaar stel laers saam met jou ry vir jare.

Dankie dat jy as 'n kundige ook dit beklemtoon dat laers nie elke jaar geruil hoef te word maar net nagegaan te moet word.

Sou jy saamstem met:

1.   Beter om 'n stel laers wel met baie moeite langs die pad in te sit as jy tussen nerens en erens is al is daar vibrasiemerke op en te gebruik tot jy weer tuis is.

2.   Eerder bogenoemde beskadigde laers van aangestelde SKF, FAG, KOYO, Timken agente te gebruik as bv die risiko te loop om nagemaakde laers te koop wat dalk van minderwaardige kwaliteit is.

i have always and still do carry a complete hub fitted with bearings and seal , greased and wrapped  for my boat trailer and caravan with spare nut and split pin , i also always have a small but full toolbox in the van every where i go, ironically the tools have always been used on the road to fix other peoples brake downs, 
two roads diverged in a wood and i took the one less traveled by, and that has made all the difference.

@Danie

Dankie Danie vir die kompliment - ons dra almal graag by tot interessante onderwerpe!

1. Ek dink wat jou eerste vraag aanbetref "Ja"! alhoewel dit nou nie die ideale oplossing is nie sou ek beslis reken dat as die spreekwoordelike kalf in die put is, dan MOET jy maar daardie reeds-beskadigde-laer gebruik langs die pad!

2. Laers wat vervalste name dra van bekende laervervaardigers is volop (by SKF het ons 'n spesiale departement gehad wat diesulke situasies aangespreek het) so, weereens ja, maak maar seker jy koop van bekende verskaffers af.

@Louvan

Now THIS is an interesting point - replacing wheel bearings on a ski-boat trailer. This happens often, and I can assure you the reason for that is more often than not that the oil seal supposed to protect the bearing, allowed water into the bearing, adversely affecting the grease lubrication. The situation is worsened when a trailer, with wheels (and bearings) still warm from the trip TO the water, is immediately pushed into the cold(er) water/river/sea to launch the boat.

Now, the appropriate remedy is this:

The reason why an oil seal is fitted to the inside of the wheel bearing hub with the little coil spring positioned to the INSIDE (bearing side) of such an assembly, is mainly to prevent grease from leaking out. With the expansion of the grease - due to heat - the seal is forced closed.  (The grease has the function of not only lubrication but also protects the bearing from foreign material i.e. dust etc. which may enter the bearing. This, together with temperature differences, "bleeding" of the grease etc. is why grease eventually gets discoloured).   In other words, with the positioning of the seal, there is not that much protection from the outside. It obviously does help, but that is not the main function, as explained above.

However, when "other" conditions exist, like water ingress, the seal cannot, therefore, protect the bearing fully. This is why it is recommended that the seal is placed inside the hub with the little spring to the OUTSIDE (away from the bearing). This will allow pressure exerted onto the seal by the water, to remain intact, and NOT let water in - far better. In your specific case, where sea water may rust this little coil spring, I will replace the spring with an "O-ring" of similar size, and voila! Problem solved!  In these conditions I will also recommend grease which can withstand water better as opposed to the normal wheel bearing grease which is aimed at protection against dust.

Dankie Nico. Hier is nou sommer baie goeie raad vir diegene wat dit nodig het. Ek dink veral die omdraai v d seel is iets wat goed gebruik kan word. Ja die ou hande gebruik dit wel maar daar is altyd "nuwelinge".

Danie,

Die manier om vibrasie skade te vermy, is om die laers so ver voor in die voertuig te ry as moontlik. Daar is baie minder vibrasie voor as agter in 'n voertuig.

Bewys hiervan, is die eiers wat jy agter in jou voertuig ry, is ge- "scramble" binne in die doppe, of die doppe is soms ook gebreek. skuif die eiers voorentoe, in die selfde voertuig, in die selfde houers, en hulle kom ongeskonde ander kant uiy.

Die selfede tel vir jou wiel laers wat verder voorentoe gekarwei word...

Welcome to the Forum

I gather you have a relatively new van as you don`t mention the year model . Older models i.e. up to 2000 had 160mm brake drums .

The  van`s currently  in use (after 2000 models ) which, if I understand it correctly, have 200mm brake drums.

These drums must use a 1949/10 and 67048/10  bearing kit  plus a 42 62 7 oil seal . Just get a  reputable brand kit  i.e SKF . Get them directly at Bearing Man

Perhaps just check with a reputable  caravan workshop who will confirm the correct kit no`s

hier is goeie inligting gegee.  hoekom die sleepwa as vervaardigers nog nie aan die gebruik van double sided seel gedink het nie weet ek nie. hulle is nie soveel breer as jou normale seel nie

Ek moet sê, ek vind dit bietjie moeilik om te aanvaar dat vibrasie 'n nuwe laer wat nog in sy verpakking is, sal beskdig nie. Dit metale waarvan dit gemaak is,is hard genoeg om die gewig van 'n voertuig te dra, so dat die baie gerige gewig van die laer self dit kan beskadig, klink vergesog.  

Ek dink nie dit is nodig om spaar laers vir 'n karavaan saam te ry nie, maar dit is seker gaaf as jy dalk op 'n klein plekke laers moet laat vervang en die plaaslike garage het nie die betrokke onderdeel nie. Ek dink egter nie dit behoort enigsins nodig te wees nie.  Wie ry spaar laers vir hulle sleepvoertuig saam wat baie harder werk? 

Om dit langs die pad self te vervang, is nie enigeen se werk nie.  Jy het jy 'n paar stukkies gereedskap nodig en belangriker nog, die gepaste kennis.  As die laers ingee, is dit waarskynlik omdat iemand wat dit "gediens" het, nie geweet het wat hy doen nie.  Ek sou aanneem iemand wat weet hoe om dit te vervang, sal wel die nodige kennis hê en self sy karavaan diens dat sal sy laers nie langs die pad ingee nie.  Met 'n bootsleepwa wat in die water gestoot word, is dit natuurlik 'n ander storie.

Ek dink nie die laer sal beskadig word in bv 'n paar weke nie. Maar ek sou wel dink dat oor 'n geruime tyd, dalk maande of meer en met 'n wa wat gereeld loop sulke vibrasies wel tot mikroskopiese "pitting" kan lei. Wanneer die laer uiteindelik gebruik word ontwikkel daai klein merkies baie vinnig na 'n groter probleem - onthou as die ding in sy verpakking is en as spaar saamgery word bly die kontak tussen rolle en "cone" altyd op presies dieselfde plek. Maar ek dink nie dit behoort mens te verhoed om 'n spaar saam te ry nie?  Ek hou van George se idee om sommer 'n hele spaar drom met laers reeds gepak en gemonteer saam te ry. In geval van 'n laer faling is dit in sy geval amper so vinnig om drom te ruil as 'n papwiel?

Jorg ek stem saam met jou en Nico. Dis ook baie moontlik dat daai spaar laer vir baie jare kan saam kamp met rollers wat op dieselfde plek druk en los en merke maak. Wat v d idee om hulle te pak met ghries en weer in plastiek toe te maak. Vir die kampers wat min te doen het kan hulle hierdie spaar laers ook elke jaar diens soos op hul karavane. coolcool

@Fred - versigtig om iets as vergesog te beoordeel as dit kom van iemand wat 50jr in die laer bedryf werksaam was.

Die moontlikheid dat 'n laer in verpakking wel beskadig kan word is wel groter as wat mens kan dink. Daar is byvoorbeeld baie duidelike voorgeskrewe reëls vir verskaffers (en handelaars) van laers  ... daar is selfs beperkinge op hoeveel laers - gemeet per groote - op mekaar gestapel mag word. Laers moet ook nie "regop" staan nie maar plat lê ensovoorts ensovoorts. Laers is selfs tyd gebonde, en "LIFO" word toegepas, anders moet die vernietig word!

Selfs die gewoonte wat baie werktuigkundiges het om die laer te draai ("spin") kan groot skade veroorsaak- geen smering, geen las, groot vibrasie, ..... ja, kaput!

Probleme kan selfs ondervind word met laers op winkelrakke lê en blootgestel word aan vibrasies. Byvoorbeeld - tydens padwerke, jare gelede, in die suidelike deel van Johannesburg, was groot voertuie wat verby die handelaar winkel beweeg het, hamers en vibrators wat die padoppervlakte bewerk het, edm. verantwoordelik vir 'n baie groot "afskryf" van laers wat deur diesulke probleme vernietig is. Die verskil, Fred, kom daarop neer dat 'n laer wat slegs "los" lê tydens verpakking, nie onder las is nie en dus baie makliker beskadig kan word. Laers wat wel gepas is, is onder spanning, onderwerp aan baie min speling en is dus baie meer beskermd (as ek die woord mag gebruik) tydens diens.

Laers KAN hard werk, maar die goedjies is ook maar "gevoelig" vir swak behandeling, soos enigiets in die lewe!cool

Spot-on Nico! Sien dat bv SKF en Timken heelwat tegniese artikels het oor die sg top redes hoekom laers beskadig word en een daarvan is die stoor daarvan wat nie korrek is nie. Is nou wel nie self 'n laer boffin nie maar my vrou se oorle' neef het ook sy hele lewe lank met die goed gewerk en ek het my "tips" alles by hom geleer....op die harde manier geleer dat mens luister vir die spesialiste!

Kyk nou net kry ons baie inligting oor wat om nie te doen wat mens nooit aan gedink het nie. Google help baie keer net oor hoe om iets te doen maar minder inligting soos die vibrasie probleem tydens stoor. Hoe weet mens dat dit dalk die stoor ook kan wees hoekom laers wel ingee kort nadat hulle ingesit is?

Danie, ja, ongelukkig is jy heeltemal korrek - daar is heelwat .... korrupte ..... handelaars wat afgeskrewe laers, m.a.w. laers wat weens ouderdom verwyder is van rakke, in die hande kry en dan verkoop. Laers het wel - ongelukkig slegs op die verpakking - aanduidings van die vervaardigingsdatum, en laers word dan daarvolgens afgeskryf.

Ek moet ook byvoeg dat ek (eintlik my komper se speltoetser .., maar ek moes dit opgetel het!) verkeerdelik hierbo genoem het dat laers volgens LIFO ("last in first out") verkoop word, wat natuurlik FIFO ("first in first out") behoort te wees. Jammer vir die fout.

smile Danie ja, interessant genoeg het ek  'n relaas geskryf vir iemand wat met 'n Menslike Hulpbron probleem sit, en toe "LIFO" op my speltoetser geberg. So wraggies toe ek die Laer storie doen kom verander my komper die oorspronklike FIFO na LIFO .... o wel!

Ek hoor wat julle sê Danie en Nico, maar verskoon my maar as ek skepties bly.  Dit klink net nie vir my logies nie maar ek sal eerder nie verder daaroor stry nie want ek is nie 'n deskundige nie.
