HPI blitz bearing question

racingdwarf · #1 01-01-2013

Hi all

Have a blitz that a play with a bit at club, after running it in the wet last week I now need to replace rear hub bearings

now the book states these are 5x10x4, good stuff as I have loads of them, but when I set about replacing them they are way to small the outer diameter of the removed bearing is more like 11mm when measured with a micrometer.

can someone who has replaced them confirm the size for me pls, just to be 100% right before I order some up

Many thanks

Ahh I can now reply to my own question

after having a good hunt about on google I found the same question on a US short course forum, it appears that HPI did an upgrade at some stage to 5x11x4 but never changed the book

.

Nice, as if you look at all the bearing sets on ebay they are all 5x10x4s so if you buy one it's more than likely not going to fit depending on the age of your truck, things that make you go Hmmmmm
