Three issues/several questions:
Issue 1: Does anyone know what would've caused the needle bearing damage in the first two pictures?
We took the transaxle apart because the snap ring holding the axle on came off when PO tried removing the hub. They pounded on hub until the snap ring let loose. We found the snap ring and it looks fine but found loose needles in the bottom of the case and traced it back to the bearing in the picture. Would the pounding have caused the damage on this bearing? If not what might've caused it? Where would be the best place to get a replacement bearing?
Issue 2: I've seen several postings on the bolts used on the ring gear failing because they are grade 5 instead of grade 8. Are those the bolts in the third picture? This is from D200 Model: 1-0611 9 Serial#: 1035982.
Was there a year WH started putting the correct bolts in? Just wondering if we need to replace them since we have it apart.
Issue 3: Is there a document that shows the torque specs for the transaxle ring gear bolts and other internal parts and for the bolts holding the transaxle onto the tractor?
Thanks.
