Default Ohc - Rear Bearing Issue

OHC- 1.5-2001-75K DONE

in a regular service, it was noticed that rear right wheel produced a "grrrrr" sound while rotating and it was diagnosed as a worn out bearing.

was clueless how bearing would have worn off so early and that too only on one wheel.

given the sloppy service levels from HONDA, i contacted ARUSH from AUTOPYSCHE and sourced the bearing from ourside and got it fitted

while fitting the bearing, it was noticed that the bearing cap ( the part shown in the below photo marked with a thick black arrow head ) was completely rusted and was almost non existent ! the centre part had fully crumbled off. the picture you see below is of the left rear wheel (even this one is on its way to collapsing soon )





now when i look at it, i realise the bearing could have failed early because of this non existent cap which would have made dust settle in the bearing and resulted it its failure.

does this cap serve any other purpose apart from protecting the bearing assembly from sucking in dirt ?

the problem now is that sourcing this cap is becoming a problem. Arush tried with the bearing supplier without luck and the lousy HONDA service first was clueless what this part is and then later said, its part of the WHEEL BEARING ASSEMBLY and hence i need to replace the whole unit ! ( quite expected of them )

could any one check whether you are able to get this part in your town ?

i have now sealed off this gaping hole which exposes the bearing assembly by putting a sheet of thick plastic at over the circular plastic part shown in the below picture ( marked with multiple arrow heads ). i cut out a thick plastic sheet and pasted it on the grey coloured plastic cap which you see below using fevicol. i presume this should be a decent temporary arrangement assuming this cap services ONLY the purpose of preventing dirt from entering the bearing assembly

pls tell me if you are able to spot this part in any of the regular shops that you may be familiar with

thanks
Narayan

My 1.5 OHC (2001) is 90K kms done now and i have never faced this problem. I'll check my car to see if similar rusting is taking place and will keep my eyes open for your cap.

are you running stock wheels ? then i think chances of rusting might be lower. because the alloy wheel exposes this part to the exterior more than the steel wheel does

No stock wheels. A 2 sets of alloys since the past 6 years.

And i believe in the funda of less is more for alloys.

thanks Tejas - I also wonder whether someone can say whether the only purpose of this cap is for keeping dirt away ?

Thank God, they did not say you have to replace the hub too. Narayan, try the local kayilankadai or try fabricating a cap for this. I doubt if you will get this at any of the regular spare dealers'.

hi narayan,

I check my OHC, hardly any trace of rust. Anyways as a precaution, i sandpapered it and applied a coat of paint on it.

I also asked around for the cap at the auto market area but no one seems to have it or asks for a sample. Sorry couldn't help.

Thanks Tejas - does your alloy design cover this central portion ? maybe thats why the cap has been protected from rust

Nope, it does not cover it fully. Its a minimalistic design.
However, during every service, as a rule, i get the wheels removed and hosed fully and also get the hubs cleaned. Maybe that practice has saved it.
