Flexplate missing teeth

Post by john777 »

I took my 2000 Safair with allison transmission to get serviced. I had been getting a grinding occasionally on start and it was confirmed that teeth from the flexplate were missing in several locations which was causing the occasional grinding. The mechanic is checking to see if he can find a flexplate from CAT.

Anyone deal with this?

Going to be expensive, drop tranny, install etc....

Call some welding shops, they can fill in the missing teeth and then grind out the right profile.

Much much cheaper than a flex plate.

i will check into that, the expensive part will be the pulling of the tranny...

Ya, I would only go new and from Caterpillar. The labor is the big issue, and a re-failure would be quite expensive.

Sorry, I forgot to mention they don’t pull the transmission. Either it’s done through the inspection hole or the starter is removed for more access.
