Model T Ford Forum: Forum 2016: How Often Should Bearing Clearance Be Checked?

If a Model T engine is maintained on a regular basis, changing the oil every 500 miles, what is the normal mileage at which one should check the engine bearing clearances?

You don't have to check them - they'll tell you loud and clear when it's time for tightening :-)

(the fourth main will tell you with ever increasing puddles of oil after a drive..)

Roger, With maintenence I generally don't wait until something makes a noise or any damage is done. Just wondering if those that put on a lot of miles have a ball park number where checking bearing clearance is prudent.

I've driven my Fordor maybe 25,000 miles and have never removed a shim. Checked it once several years ago and it was still at .0015, just where it was when rebuilt.

I have just removed my engine for it's annual check. My main and rod bearings are 0.002" to 0.003". I drive my 1926 TuDor around 5000 miles a year and change the oil between 1000 and 1500 miles. Last year coming home from the Michigan Jamboree I heard a new noise that I thought was a rod, but turned out to be a triple gear bushing. I'm not very good at analyzing engine noises, but I do know a bad bearing or bushing when I see one, so I look more often. You probably don't have to check too often, but it can't hurt to look once in while, (every other year?) it's not a difficult job. Mike
