KC9KAS 4,744 #1 Posted January 13, 2010 I have a 1975 B-100 Automatic (1-0511) less the engine. I recently aquired an engine, but not sure it is the correct one. Does anyone have a really good picture of how the engine is mounted? My frame has several (mounting?) holes, and the 2 closest to the front axle are threaded. I am not having much luck lining up the holes on the engine pan to the holes in the frame. :thumbs: Share this post Link to post Share on other sites
pfrederi 18,644 #2 Posted January 13, 2010 No pix I do not have a 10 hp but I think 2 bolts go up through the frame into threaded holes in the oil pan and 2 go through the frame and a flanged hole in on the oil pan...if you have the correct motor/oil pan Share this post Link to post Share on other sites
rmaynard 16,292 #3 Posted January 14, 2010 According to my info, the engine is a K241S. It mounts directly to the frame on the holes shown in the diagram. Hope this helps. Bob Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #4 Posted January 14, 2010 The '74-'75 B-100 models were just discussed here not long ago. They are a medium frame tractor -- which places the front two engine mount bolts directly over the front axle. Since the left front bolt will push up through the unthreaded oil pan hole for installation, it is just like the other tractors -- but the right front corner is secured by a J bolt attached under the lip on the bottom of the frame. You can see the J bolt in the first picture in this post: http://www.wheelhorseforum.com/index.php?showtopic=4420 Share this post Link to post Share on other sites

I think I gave the wrong info. My B-100 (1977) is what I based the info on. I was not aware of the other frame on early B-100's Please disregard and follow TT's advice. He is infinitely more versed on these horse than I. Bob Share this post Link to post Share on other sites

The two right side bolts go up through the frame and into threaded holes in the bottom of the oil pan. You should be able to reach up under the frame near the oil pan corners and feel the bolt heads. My B-100 (1977) is what I based the info on. I was not aware of the other frame on early B-100's The 1976-77 B-60/80/100 are "long frame" tractors They're basically a stripped-down version of the C series and were only available with the 8 speed Uni-Drive. The 1974-75 B-100 was automatic (hydro) only and those models, along with the 1974-75 B-80 4 speed, used the "medium frame". Share this post Link to post Share on other sites
KB9LOR 4 #9 Posted January 14, 2010 I know there are supposed to be there but I have none in the oil pan, will have to go and check it again. Share this post Link to post Share on other sites
