Guys ....question here ..are the main bearings in a 20b the same as a regular 13B?
i know the rotor bearings are the same , and in case i have to get them , where can i get these main bearings?

 

They should be the same?

 

#1 & #3 same as 93 REW. #2 is dedicated.
# 1 & 3, can be sourced though Your local dealer. # 2 here in the US. through Mazda Motorsports. exclusively

We can help You with that if you can't get service fron them.

GT1-20b

 

How do i contact you??!!

 

I need the center bearing too!

thanks

 

Mazda Trix has the center bearing also. I ordered one through them when i did my rebuild. I think it was about $45 at the time. I use REW bearing for the front and rear also.

On a side note. Does anybody know the running clearance for the center bearing?

 

Mazda Trix part # 10-E420-NF01 it's now $58.14 and a 3 day lead time.

 

Either send me a PM, or call at (305) 235 3696
If no one answer, then leave a mesage.
I've been traveling a great deal lately, but I check my messages on regularly basis.
Pm's work great !

If Mazda Trix does have them, they are a good source also.
Make sure they are MAZDA OEM.

 

I am sure i can get the center bearings for less than that will check and post my findings.
I know i can get the gaskets for less than the guy selling them on ebay.

hmmm there are two bearings listed for the center one of them is shown as " O.S. "
wonder what that means..
will check tomorrow on pricing.
matt

 

I also see that they use 2 different part numbers for the front and rear
the rear being this " O.S. " size.
I will check the price on all of them
matt

 

Now,

O.S might be Over Sized bearings. I have a brand new E shaft so I'll just use the stock sized bearings if we can figure out Mazda's coded bearings

 

o.s as in smaller inner di. i am guessing as well.
sorry didnt have a chance to check pricing today, to much on the go
matt

 

this is great stuff guys ...i will call mazdatrix to see whats the deal , in any case i will also post my findings later today!

 

will know tuesday what the pricing is, forgot it was a long weekend and the
guy i needed to ask was off already on a trip.
matt

 

well i did some checking and it would appear that the 3 part numbers i checked for the
bearings for the 20b are no longer available
they did change up to a single part number which prices out for around the $40 mark
it is still a cosmo part number so i am guessing it is what is needed for the 20b.
