Tz22da New Holland Rear 4x4 PTO Seal Replacement, what did I do wrong?
Have a 2006 TZ22DA New Holland Tractor. Purchased used with 300 Hours. When purchased noticed the 4X4 Hydraulic Rear PTO(that drives the 4x4 shaft to front wheels) was leaking at seal. So after I done a hydraulic/hydrostat change when first purchased leak didn't go away. Have about 315 on it now and thought I would try to change the Rear PTO Seal. Drained about a gallon of fluid from lower HST bolt and took off old seal. Put new seal in. Prior to putting seal on, placed extremely small amount of petroleum jelly on the outer and inner diameter of seal-as I read on forum its recommend. Put fluid back in and as soon as I placed at full mark, I noticed about a 6 inch puddle from the fluid flowing from seal I just replaced. Now leaking worst then before. What did I do wrong any Ideas? The tractor runs great, beside the leak. New to tractors, but somewhat mechanically inclined. Dealer wanted $300 to fix, so thought I would try to do self, part was $11 and time was free. I drained gallon of fluid out, so more fluid didn't drain out of the seal area.
Some ideas thought I may of done wrong:
1. Maybe should of put grease or petroleum Jelly everywhere inside/inner outside of seal seal. Noticed that new seal has more of a cylindrical grove on outside then on seal before the seal rubber touches shaft on outside, maybe I can put grease there.
2. Area to get to seal in was hard to get to, stuff in the way. Got the seal in flush, but not easy. Couple very small dents outside on the middle on ring on seal, but dent not on rubber area. Not that bad.
3. Maybe I should have replaced the sleeve to, although looked really good.
4. Saw some forums say the seal could of got rolled, due to bad spring. Some forums mentioned since this new holland seal was single, should get an aftermarket 2 seal style.
Here are some pictures, the illustrations shows the seal I'm mentioning, no.2 (SBA050209122)
Thanks
