I need to know what size the bearing is for the .26. I can't find the info on it.

I do have to say I like the Matrix, but I have not had much luck with the engine. I only have about 12 tanks through it and I can not get it to run worth crap. (won't idle right, stalls at random, High temp, ect) I even had a guy who has been racing for years try and help and it was baffling him. I even went as far as taking it apart and sealing it but it just will not run right. Now this last time out to try and get it to run, it seems the front Bearing is leaking.

does anyone have a suggestion

thanks

Hi - I looked for a size on the front engine bearing but we don't have one listed. I do however have the part number for a replacement bearing: G70349-17 and retails for $17.99.

Also, please email [email protected] for information about the NX-26 engine.

ive replaced the front with a sealed bearing. dont remember what size it was, but i remember it was easy to find the answer.
just measure it. there are 25.4 mm in one inch

if the bearing measures .625 or 5/8in, multiple .625 x 25.4 = 15.875
then the bearing is more then likely to be 16mm
got it?

oh yeah, make darn sure you remove the seal from one side and wash out the grease... very important
add a drop of after run to the bearing and install open side in. this allows the fuel to lubricate the bearing and there is less resistance than grease at 30,000+ rpms.
