Metric 200 question

[PozQB14]

This is kind of off topic but still a metric question. Has anyone ever broke a rear end gear set and as a result hurt the transmission, specifically a metric 200?

Turbo Action also has a bellhousing for Metric 200. Check with them.

Common problem not only related to TH200's. Anytime you tear a ring & pinion out, it's a good idea to drop the pan on the trans at the same time. Banging from the rear end often causes roller clutch (sprag) failure.

Would think cracking the bell is caused by stress from chassis flex.
There is ET in a stiff chassis.

Where/when will you notice the failure? I put new gears in the car just so I can move it. I started the car up and just went forward and reverse to put it in the garage and nothing seemed out of whack. Ill definitely drop the pan, would I feel a difference in higher gears?

I wouldn't bother running it. Drop the trans pan and you'll probably find evidence of a torn-up rear sprag with small pieces of rollers and springs in the pan. Common event when you tear the rear out.

If it was a violent break on the starting line you definitely better look. I have broken one 350 and one 200 planetary that way.

Its weird. car launched great, wheels came up way higher than normal. 330' time was the best ever, then BANG! gears were lost. pulled over as fast as a I could to the wall, checked for leaks, towed to the pits in neutral.

You probably won't be able to tell if the low/rev sprag is on the way out , that way.
It needs to be inspected physically , at least annually, in my opinion
High maintenance item on the 200.
If anyone knows of an upgraded unit, I'm listening.
