Swivel bol met vet ipv olie

[e.nagtegaal]

de swivel bollen van mijn series 3 roesten dezen wil ik vervangen nu heb
Ik heb begrepen dat bugdgetparts vet levert wat hier in kan heeft iemand hier ervaring mee

Officieel horen in de swivel bollen van een Series *olie* en geen vet vanwege de benodigde spatsmering van één van de draaipunten. Dat spatten werkt met vet een stuk minder.

Maar het is een veel gevoerd debat: er zijn heel veel mensen die zeggen "Vet gaat bij mij al jaaaaaren prima". En anderen zeggen "Zeker niet doen, niet voorgeschreven, dus niet de bedoeling!".

Conclusie: *eigenlijk* hoort er gewoon voorgeschreven olie in en niet zonder reden, maar je moet het uiteindelijk zelf beslissen

Als je toch je 'Swivel Balls' gaat vervangen moet je de 'Housings' gewoon met olie vullen.

Als je meteen alle keerringen vervangt gaat het echt geen olie lekken (hooguit een beetje zweten maar dat is goed tegen de roestvorming).

Wil je toch vet gebruiken kan je net zo goed de roestige 'Swivel Balls' laten zitten.

Edwin,

It's a long time since we did the Oil vs Grease debate and always an excellent topic to get the Forum members split into two separate camps with abuse and large metal objects being thrown over the fence. It always provides endless hours of pleasure for the reader.

Now as this is the Techniek section rather than Kroeg I'm not going to voice an opinion (I have one and not the one that most people would think), however what I will give is the Technical reasoning behind the two lubrication methods and the pros and cons of both. Ultimately, as Jan says, it's up to you to decide which works for you.

Series vehicles up to 1985 (excluding Stage 1 V8 and the 1st 1,000 build 80" Series 1) have selectable 2WD/4WD. The front axle comprises of a differential and 2 half-shafts with a small Universal Joint (RTC3690) housed in the swivel allowing steering and drive. At the axle end of the swivel ball is a roller bearing (244150). Lubrication to these is provided by Oil (EP90) sitting in the ball and swivel housing. Oil is prevented from escaping between the ball and the housing by a seal (RTC3528) and the housing and the hub (from 1980) by a seal (FRC3099). In 2WD without freewheeling front hubs, the front road wheels will turn the half-shafts and differential and front propshaft and lubrication is provided to the UJ and bearing via the "splash method". In 4WD the transfer box will drive the front propshaft, differential and halfshafts and ultimately the hubs again lubricating via the "splash method". In 2WD with freewheeling hubs the front road wheels turn independently of the half-shafts, the UJ and bearing receive minimal lubrication and only sit in EP90.

Land Rover 90,110 and 130, Stage 1 V8, Discovery 1 and Range Rover Classic all have permanent 4WD (ok apart from the selectable 2WD Santana LT230R variants). All have a constant velocity joint (FRC2930/FRC2931 in the case of the Stage 1) and no bearing. They do have however an oil seal (571718) at the axle end of the swivel ball. Lubrication is provided to the constant velocity joint via EP00 grease (STC3435). The swivel ball seal and stub axle seal are the same as post 1980 series vehicles. As drive is provided all the time then the CV joint is always moving and as there is a greater surface area of moving parts on a CV joint than a UJ thicker lubrication is required due to heat build up, hence the EP00.

Oil in Land Rover 90,110 and 130, Stage 1 V8, Discovery 1 and Range Rover Classic does not work even though originally it was used and drain plugs were fitted to the housings. Land Rover issued several Technical Bulletins to this effect and insisted on the use of EP00. (see attached)

EP00 in Series vehicles is a contentious issue. There is no barrier between the axle and swivel housing so the oil and grease are free to mix within the axle casing itself. In 2WD with Freewheeling hubs there will be zero lubrication to the UJ and bearing other than a covering that they have. In 4WD or 2WD without freewheeling hubs the UJ and bearing will be lubricated but the lubricant is not as free flowing as EP90.

However it's not as simple as this. Many factors such as outside temperature, duration of drive, terrain driven, freewheel hub usage, amount of leakage, frequency of vehicle maintenance and so on.

I have had many Series vehicles (I still drive a Series III LWT) and also later vehicles. As I said earlier I have a personal preference which based on my own experience works for me and I have never had a swivel, UJ or bearing failure in 30 years.

Rob,

Zoek eens op waar de 217400 zit bij een series landrover.
Er is dus wel een scheiding tussen ashuis en fuseehuis.

Gr Bram.

je maakt me nieuwsgierig Rob ... wat heb jij (los van je voorkeur, ik houdt het púúr technisch gezien de rubriek waar we nu zitten ) nu in je LWT-bollen zitten?

[janwijbrand]

Met zulke gedetaileerde antwoorden, waarna feitelijk weinig te discusiëren meer overblijft, worden de draadjes wel erg kort en saai

There is indeed an oil seal in the end of the axle, however I have never known it to seal oil either in or out but you are correct.

je maakt me nieuwsgierig Rob ... wat heb jij nu in je LWT-bollen zitten?

EP00 swivel grease of course.

Well /Oh, $@%#& ... change to the Noord-Nederlands language-mode / ....
Je kan natuurlijk ook zeggen dat smeren met zg "Swivel Grease" tot de latere/laatste inzichten hoort. En je kan ook aannemen dat de permanent-aangedreven assen meer te doen krijgen als de meestentijds niet aangedreven series-vooras. De enige vraag die je je moet stellen: hoe houden de olie-keringen het en hoe zijn de UJ's in de series as gecontrueerd, ofwel zou smering met EP00 afdoende kunnen zijn.

Bovendien, ook als je, of misschien wel zeker als je vrijloopnaven hebt blijft "Swivel Grease" min of meer "plakken" terwijl olie op de iets langere duur alleen onderin staat zodat alles wat boven de olie uitsteekt uiteindelijk droog komt te staan, en wat droog staat gaat roesten.

However it's not as simple as this. Many factors such as outside temperature, duration of drive, terrain driven, freewheel hub usage, amount of leakage, frequency of vehicle maintenance and so on.

In my humble defense m'laud, I have only owned one Series vehicle with freewheeling hubs and they were engaged at least once a week (it did drive 1.120,00kms each week) and as I said earlier it does depend on a number of factors.

My personal reason is that the English are c**p at making oil seals and I have never had an oil filled swivel that hasn't leaked even when all the components were replaced with new ones (and not even S**tpart ones). Just because I give advice based on years of ownership and practical experience both personal and professional doesn't always mean I follow it, hell I have friends who are Doctors that drink, smoke and eat fast food but tell me not to

Rob (who likes the feel of a sachet of EP00, so my secret is out)
