4cyl or 8cyl pilot bearing

['88WhtNtchBck$]

my buddy said using a 4cyl trans with a 8cyl pilot bearing would be fine, i would just like some more advice or expert opinions, thank you!

It will work but I have been told it could do alot of damage. It will work because the 8 cylinder bearing is larger than the 4 cylinder shaft so it will go in no problem. What you should do and it is also what I have done in the past is change the pilot bearing to match the trans you have. 4 cyl tranny = 4 cylinder pilot bearing, 8 cylinder tranny= 8 cylinder pilot bearing.

get the 4 banger unit, its $7 dont get cheap on bearings, especially this one!!! oh yeah enjoy the gear set, its wicked!!

Don't use the V8 pilot bearing. The input shaft is supported at the end by the pilot bearing and since the 4cyl T5 has a smaller diameter end on the shaft, it'll move around and cause damage in the trans. The part number you need is #14672 at Autozone. It's for a diesel Ford Ranger.

yea i should of trusted myself but small problem, the bearing is already in, but i got the trans for $100 dollars and want to upgrade it, will the trans damage to the bearing cuz i don't want to take the clutch n flywheel out again to swap the new one

It'll probably do damage to both the pilot bearing and the trans itself by using the wrong one. I bet you'll notice quite a bit of vibration, too, since the input shaft (and clutch disk) will be bouncing around.

+1. You will get a wicked vibration at 80-90MPH. Over 100+ will be unbearable. A 4cyl PB will not fit in a 8cyl crankshaft. Not only is the hole bigger the entire bearing is bigger.

Through massive amounts of searching, here's the end of this thread.

Use BCA 202-SS or 14672 bearing from Advance Auto, AutoZone, or wherever. They both measures .5906 ID and 1.378 OD. and cost about $15
