Jake Collie 3 #1 Posted August 6, 2020 Hello all. Was in the shed last night and noticed an oil pool under the left rear tire on the 520H. Looks like I will be changing the axle seal and bearing. It appears I will have to take the whole transaxle apart to get to the bearing. Is this correct? Thanks. Share this post Link to post Share on other sites
pfrederi 17,867 #2 Posted August 6, 2020 Bearing yes disassemble... seal only not necessary. jack her up and remove wheel. Try moving axle up down front to back . Shouldn't wiggle. if it does bearing will have to be replaced. Some in and out movement up to about 1/8"" is OK Welcome Share this post Link to post Share on other sites
Jake Collie 3 #3 Posted August 6, 2020 Thanks for the reply. Unfortunately the axle moves up and down. Looks like a ball bearing inside and needle bearing outside. Time to get oily. Share this post Link to post Share on other sites
pfrederi 17,867 #4 Posted August 6, 2020 Needle bearing is B-1816 Seal is SKF 11124 I do not recall the ball bearing # off hand. (my tractors are all older) But they are less prone to failure.. Share this post Link to post Share on other sites

lynnmor 7,354 #8 Posted August 6, 2020 If you have a lot of play there is a good chance that the axle is knackered. The axle is hardened and ground in the bearing area and that cannot have even minor damage. Share this post Link to post Share on other sites
