Wheelhorse100 3 #1 Posted March 25, 2016 (edited) Hi I have a wheel horse raider 10 . With a 12 horse Kohler. I'm looking to do some pulling with it. If I jack it up and spin the tire one way and other tire spins in the opposite direction. Will the transmission hold up or should I replace it, with a stronger one Edited March 25, 2016 by Wheelhorse100 Share this post Link to post Share on other sites
953 nut 55,964 #2 Posted March 25, 2016 Your Raider came with a 5073 transaxle which is a good strong unit, but you may want to look for a 5058 which is a limited slip unit. The attached list will show you what transmission came in each model. wheelhorseallyears (1).pdf 1 Share this post Link to post Share on other sites
Racinbob 11,260 #3 Posted March 25, 2016 (edited) That's normal for the wheels to spin like that when jacked up. You have the 10 pinion differential and is mighty tough but the 8 pinion is even tougher. I would use it and if it gave you issues see about making a swap.

stevasaurus 22,884 #5 Posted March 25, 2016 So what year or model number is your Raider 10 with a 12 hsp Kohler?? The Raiders, through the years came with a 4 pinion with 1" axles...a 5071 (6 speed) and the 5073 (8 speed). Your model number will tell us which one you have there. Do you have a hi/low option on your transmission?? Do you have 1" or 1 1/8" axles?? Is the brake drum shaft in the hole closest to the axle housing or in the next hole toward the front of the transmission?? 1 Share this post Link to post Share on other sites
Wheelhorse100 3 #6 Posted March 25, 2016 It's a 1972 wheel horse raider 10. The original ten horse had a cracked block. So I replaced it with a 12 horse Kohler. The transmission has hi and low. It has 1 inch axles 1 Share this post Link to post Share on other sites
stevasaurus 22,884 #7 Posted March 25, 2016 OK...that is the #5086 transmission. That has a 4 pinion differential and 1" axles. Nothing wrong with the transmission as far as pulling, but if you are going to get serious about it...you want an 8 pinion differential with 1 1/8" axles. I would stay away from a 10 pinion limited slip differential for pulling. Differentials to look for...5091, 103907, 103916, 103918. 2 Share this post Link to post Share on other sites

stevasaurus 22,884 #10 Posted March 25, 2016 Richard, I am just going with what the guys that really do the pulling say. Read some of the threads that are in the "Pulling Section"...they all like the 8 pinion differential with 1 1/8" axles. Personally, there is nothing wrong with any of the Wheel Horse transmissions...when you use them for what they were designed. The thing I think the pulling guys don't like is that the 10 pinions kind of float in that differential...they are not on a shaft like the 4 and 8 pinion differentials. I think they have a tendency to chip easier in the 10 pinion, limited slip. I am not sure I am right in my thinking, but that is what it seems like to me. Actually, Wheel Horse came out with a Service Bulletin that shows what to do to take a 10 pinion, limited slip differential and make it an 8 pinion differential....the Service Bulletin is not about doing the operation the other way. gotta be a reason. 2 Share this post Link to post Share on other sites
Racinbob 11,260 #11 Posted March 25, 2016 I should make it a habit to check the list before I reply. I thought all Raiders had the limited slip. That's a great explanation Steve. The floating pinion thing sure makes sense. I was leaning towards that round spring thingy being a weak link but you make better sense. I can say my Dad bought a Raider 12 new and 30 years later and countless hours of brutal work the thing never gave him a problem. Even the limited slip still worked good. Probably just lucky. After he passed my nephew used it a while then my Mom sold it. I screamed MOM!!!!! She said she didn't think I would have wanted it. I guess that's what I get for moving down here. 1 Share this post Link to post Share on other sites
stevasaurus 22,884 #12 Posted March 26, 2016 Bob, I had an advantage about which transmissions came in the Raiders. My 1972 Raider with 1" axles. 1 Share this post Link to post Share on other sites
Racinbob 11,260 #13 Posted March 26, 2016 Looking at the list I see that in 1971 both the Raider 10 and 12 had the 5073 but in 1972 the 10 had the 5086 and the 12 the 5073. I swear that Wheel Horse had a special department dedicated to messing with the minds of folks 40 years later. 2 Share this post Link to post Share on other sites
stevasaurus 22,884 #14 Posted March 26, 2016 I'm thinking the same thing. Imagine all those engineers sitting in the room going over plans for the next year of Wheel Horse tractors....and one guy says.."OK, but what about Bob?" 1 Share this post Link to post Share on other sites
