seizes in 3 minutes?

Usually this can be repaired with a good clean of the crank and if necessary a real bush .
Crank will clean with HCl ( Muriatic acid ) from a pool shop .
Then see how much slop is there
Usually it siezes when you are driving across a long slope.

Just remember to neutralize the acid and don't get it on any good aluminum. Will need to be heavy oiled after neutralization or the metal will flash rust.

Note on safety: Use the acid only extremely well ventilated area with the air from your back so you don't breathe in the fumes as they are very dangerous. Can actually take your breathe away especially if you have already have lung problems like myself.

In fact, do it outside.
If you allow the acid fume inside your workshop it will atack everything it lands on, partcularly things with sharp edges like drill bits.
