KW88 31 #1 Posted May 5 I have an 88 312-8 with 1-1/8" axles. I need to replace them and the seals. Anyone know the part #s and where to get them? Share this post Link to post Share on other sites
squonk 41,291 #2 Posted May 5 Try A-Z tractor for the axles. https://www.a-ztractor.com/ You will have to split the transmission and remove the differential to replace the axles. you also will probably need inner and outer axle bearings. You can get them here: https://wheelhorsepartsandmore.com/product-category/manual-transmissions/ 2 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,090 #3 Posted May 5 Information lists the 1988 312-8 as using a transmission with 1" axles and 4 pinion gears. Perhaps it is not the original transmission? 2 Share this post Link to post Share on other sites

stevasaurus 22,841 #5 Posted May 6 Try to measure the total length of both axles while in the trans...try using a framming square. Then divide that by 2 and that length will be close enough to know what axles to get. This is assuming your trans is not a Limited Slip trans. Those axles are different lengths. The seals for 1 1/8" axles is SKF 11050. 1 Share this post Link to post Share on other sites

KW88 31 #7 Posted May 7 Found these marks in casting. Can this identify any type of model transaxle? Share this post Link to post Share on other sites
KW88 31 #10 Posted May 7 I'm not by any means an expert when it comes to this stuff or how to source info so any help will be greatly appreciated. Share this post Link to post Share on other sites
stevasaurus 22,841 #11 Posted May 7 Take those bolts out of the top of the trans and shine a light down one of those bolt holes. Look down the dip stick hole and see if you can see the bolts holding the differential together. If it looks like 5 you have a Limited Slip transmission. If it is 4 bolts, you have an 8 pinion differential and the axles are the same length. The axles can butt together in the differential and have up to 1/8" slack of play. Your 23 1/2" would break down to 11 3/4" axles which is Part # 102764 in a #5091 transmission (if this is an 8 pinion differential). If this is a limited slip trans, the axles are 1. 12" Part # 7202 and 2. 11 1/4" Part # 7273. This adds up to approx. 23 1/4" Sense you are looking to change out axles, I would open it up and go from there. You can probably get parts in a couple of days from one of our vendors. Hope that helps. 2 Share this post Link to post Share on other sites
