chris11 184 #1 Posted March 14, 2013 I got a k 91 with this rj im building. what type air filter do they have on the rj? oil bath? or round pan style? also The exh port isnt threaded for pipe has 2 holes for 1/4 20 for flange. anyone have a picture? Share this post Link to post Share on other sites
VinsRJ 721 #2 Posted March 14, 2013 The RJ would have had an up-draft oil bath air filter and a tapped exhaust port and no bolt provisions. I can get you pics later tonight unless someone beats meet to the punch. Share this post Link to post Share on other sites
wallfish 15,907 #3 Posted March 14, 2013 I have a tap to cut the NPT threads for the exhaust port if you want to borrow it. The updraft oil baths are very difficult to find but you can convert a down draft filter to updraft if it has the steel bowl. Some bowls are made of plastic.

Jake Kuhn 1,547 #5 Posted March 14, 2013 From what I have seen the only rjs that used oil baths are the k90s the.k91s had the regular filter like the newer horses used.

64s 83 #6 Posted March 14, 2013 I've had the same experience as Jake. My K90 has the updraft and my k91 has the regular (or pancake) style air filter. Of course, there's always room for oddities during a changeover. Share this post Link to post Share on other sites

chris11 184 #9 Posted March 14, 2013 Ok what is the correct engine K90 or K91 ? Share this post Link to post Share on other sites
VinsRJ 721 #10 Posted March 14, 2013 Early RJ58 would be K90... Later production RJ58 K91. Share this post Link to post Share on other sites
wallfish 15,907 #11 Posted March 15, 2013 That's kind of the beauty of RJ-58s. So many variations to the same model which make them fairly easy to get factory correct. recoil starters, front rims, rear hubs, seats, hitches and quite a few other things have variations to that model too. Seems like the list goes on forever. One thing which does seem fairly constant over the years is previous owners cutting up the hoods. Share this post Link to post Share on other sites

VinsRJ 721 #17 Posted March 15, 2013 Chris, thats because you came with a dragster... think back to the muscle care days... you want a 70 Chevelle with the SS/454 on the side... or a plain-Jane Cutlass S with a 455? LOL! Lets also keep in mind that the club has really made it a point the last couple of years that the crazy behavior has been pissing them off. AKA: The balance table.

Lane Ranger 10,472 #19 Posted March 15, 2013 My brother has one 1959 RJ Wheel Horse that has a different air filter on it than the oil bath or front facing air filter on the carb of the K 91 motor. The attached photo is of a Kohler metal cannister air filter that contains the paper element. It is a drop down mount cannister . The paper element canot be replaced and you have to change the whole cannister when it is time to replace the filter. I have seen a quite a few RJ's at shows. Not sure if it was an original item on some Wheel Horse RJ's or came from other spec motors installed later on RJ's Looks nice on the tractor and operates well too..

rydogg 186 #22 Posted March 15, 2013 Here is a k90 that I setup with a updraft oil bath from a Clinton engine they are a little smaller but easier to find. Share this post Link to post Share on other sites
WHRNaddict 5 #23 Posted March 17, 2013 That looks like the one setting on my work bench, only now it has the correct filter. I'll part with the under size filter if anyone has a need. Share this post Link to post Share on other sites
