Hours 7:30 to 5:00 EST M-F till noon on Saturday. THIS IS A REPLACEMENT GEARBOX FOR YOUR BUSH HOG RZ160 RZ60. Replacement for the following part #s: U920580000, U9.135.800.10 COMER, U9.205.800.00 COMER, U913580010 COMER, 101ST COMER, 45PRC30147-N HICO, 81444 BUSH HOG, 826-384C LAND PRIDE, 9.119.000.20 COMER, 9.135.000.20 COMER, 911900020 COMER, 913500020 COMER. Here are the specs on the box. 40 horse power gearbox. Standard 1-3/8 smooth input shaft(where the pto shaft hooks on). The pto shaft is held on by a 1/2 shearbolt. Length of the input shaft out of the gearbox is 3 long. Gear Ratio: 1 to 1.47. Bolt hole pattern for mounting is on the corners, 4-3/4 center of hole to center of hole. It takes a 5/8 bolt. 12 splined output shaft(where the blade carrier hooks up on the bottom). 1-9/16 outside measurement over the output shaft splines- from the base of the output cap to the end of the splines is 2-3/4″ long- overall length of the output shaft is 4-1/2″ long. Takes a 1 threaded castle nut and a carter key on the bottom of the output shaft to secure blade pan(which is included). Overall height of the box from the top of the mower deck to the top of the box is 9-1/2. It takes 80-90 gear oil. Look at the pictures and the one of the back of the gearbox, you will see a plug on the top and a small little pipe plug on the bottom right side. The top hole is where you put the oil in, you take out the pipe plug and as you pour the oil in and when it starts running out of the pipe plug hole then it is full. You only fill the box roughly half way, if you overfill the breather plug will release some of the pressure but you also run the risk of blowing out one of your oil seals so try to maintain adequate oil levels. Of course you do this with the box mounted and in an upright position. We stock all parts for everything we sell. Thank you and God bless.
