Wats up guys, so i picked up a 90 integra for parts last year. It came with the stock b18a engine and ysk-1 tranny. I took the tranny apart to check everything out and discovered that the top ball bearing on the countershaft was destroyed like in pieces.
I ordered number 14

Well its not the right bearing it doesnt fit



This is a cable ysk-1 tranny the bearing that I ordered should fit right on top of the needle bearing. The ball bearing that I ordered doesnt fit on top of the needle bearing and doesnt even fit in the tranny housing.
I did some research and it looks like the ball bearing for the 95 b series trannies number 13 should fit right


Has anybody had this problem or know anything about which ball bearing it is?????

 

maybe a part for a 92-93 integra got ordered instead of a 90-91??

 

This is probably better suited for the transmission/drivetrain forum. Lots of knowledgeable folks in there.

 

What part # did you get?

91003-P21-003 is for 92

91003-PG1-018 is for 90

 

i have two a1 trannys that im about to toss. Ill give you the bearing if you need it. I'm not to sure what a ysk-1 tranny is though. Is this car stock? it thought these years only came with either a1's or s1 trannies.

 

thanks guys, its seems that i have a 92+ tranny in a 90-91 car. The ecu code is 37820PR4A10 which is obd0, but aparently the bearing is from a 92+ integra. The dimensions from the 92 and 95 bearing are the same, only the 90-91 are different. I got ride of the shell a couple of months ago and I honestly dont know the exact year of the car. The engine is definately obd0 as well as the ecu, so I just assumed I needed a bearing from a 90-91 teg.
It seems that the s1 and ys1(I think ys1 and ysk-1 are the same) are the codes from the 90-93 trannys. Ive heard a1 used but i donno if they are referring to the block code 18a1. If the trannys you have are from a 92-93 teg il take the bearings.

 

The YSK on the trans means nothing...you will see that on a lot of different transmissions...Looks like it may be the Company that was doing the casting for the casings...kinda like Denso does electronics. That is my guess but, what I can tell you for sure is that YSK is not the way to identify it.

You will need to identify it by the sticker that is affixed to it..if it does not have that then you can do a tooth count since you have it open.

Good luck and let us know what you find!!

A-1 and S-1 trans are 90-91

YS-1 is 92-93 and has interchangeable parts with Hydro transmissions

 

sorry man, only 90-91's.
