mowerman1193 38 #1 Posted Wednesday at 04:25 PM Anyone happen to know what the part number for the rear axle hub would be for this tractor? Looking up the parts viewer on Jacks Small Engines and I can't find a hub in the diagram or any part numbers. Thinking the keyway is bad in mine as the hub is not stuck to the axle will move in or out close to half inch.. I've never been able to lock this thing down and make it stay.. always works its way inward and then my chains start grinding on my fuel tank / fender mount... I can't seem to get it to come off.. and just ready to cut it off and buy a new / used hub.. will make sure axle key is good first of coarse. Share this post Link to post Share on other sites
kpinnc 12,850 #2 Posted Wednesday at 04:30 PM If memory serves, the 1642 is an Eaton hydro. If that is the case, any 1.125 (1 & 1/8) ID Wheel Horse hub will work. See our vendor section and you should find what you need. And yes you will need to make sure your axle is OK. Due to Woodruff keys being used, often the axle damage comes with hub damage.

Bill D 2,015 #3 Posted Wednesday at 04:53 PM Should be a one inch axle. A-Z sells a taper lock hub that will work with a damaged keyway. 2 Share this post Link to post Share on other sites

pfrederi 18,019 #8 Posted Wednesday at 05:15 PM Unless I am really missing something here it uses 1-1/8 hubs part #105763 1 Share this post Link to post Share on other sites
mowerman1193 38 #9 Posted Wednesday at 05:17 PM The problem is the manual shows hubs for both the GT-1600 / 1642 and also the hydro model GT-1800 / 1842 and I believe I have the 1" hub and the hydro has a 1-1/8 hub.. but they don't show what part number is what size hub.. I did see A-Z on eBay that sold the tape lock two piece hub in case my axle is damaged. Share this post Link to post Share on other sites

mowerman1193 38 #11 Posted Wednesday at 05:23 PM I can get my calipers out and measure my hub / axle to be sure but I've read a lot over the years that the 8speed work horse has 1" and the hydros have 1- 1/8.. but what part number correlates to what size? LOL I use Jacks and other sites more for looking up parts for part numbers.. as above reply states.. I get the number and then go search for that number often times finds a brand new part much cheaper.. Thanks to Paul for the parts download pdf.. now I don't have to use these sites to look up the numbers.. 2 Share this post Link to post Share on other sites
Bill D 2,015 #12 Posted Wednesday at 05:32 PM I have a GT1642. It's original and it has 1" axles. The GT1800/1848 are Eaton hydros with the 1 1/8" axles. The GT100/1142, 1600/1642 are all 8 speeds with 1" axles. Share this post Link to post Share on other sites

This is one of the issues I have with these manuals and parts viewers.. I can measure my axle to verify the size but it is the 8 speed trans not the Eaton hydro.

Handy Don 12,674 #14 Posted Wednesday at 05:33 PM Deailing with A-to-Z will be helpful if (as is likely) your axle is munged around the woodruff key slot. Avoiding the transaxle disassembly needed to replace an axle can make the cost of the taper lock hub look pretty reasonable! 2 Share this post Link to post Share on other sites

Avoiding the transaxle disassembly needed to replace an axle can make the cost of the taper lock hub look pretty reasonable! A properly installed taper lock hub is a good investment in several ways.... requires even torque to seat and MUST be installed on an axle that is not chewed up. It may be used either with or without a woodruff key. It ie easy to install and remove later on - it is it's own puller! It is transferrable to another Unidrive of the same axle diameter - The inner TaperLok bushing should be of an Industry standard design - there are different sized "families" - MAY be possible to change to a storebought 1" bushing??? 1 Share this post Link to post Share on other sites

Yeah, since I need a new hub anyway, I'm thinking I'm just going to order this and cut the old one off.. Then I'll be done with it.. Share this post Link to post Share on other sites
mowerman1193 38 #18 Posted Wednesday at 06:28 PM Just to confirm for anyone finding this topic at a later date.. I measured my axle and it is 1" on the 1983 WorkHorse GT-1642 with 8 speed trans.. 3 Share this post Link to post Share on other sites
mowerman1193 38 #19 Posted Wednesday at 08:14 PM Well I was able to get the hub off finally and it is definitely chewed up in the keyway area and the axle is too but not really bad.. but bad enough I didn't want to chance a new hub so I ordered the repair hub from A-Z.. little concerned about the spot where the second hub securing bolt went in on the axle as the keyway being buggered out allowed the hub to slip on the axle shaft and that second bolt chewed into the axle a bit. I'll have to file it down around the edges of that area. Hopefully this repair kit will hold up. 1 Share this post Link to post Share on other sites
ri702bill 8,577 #20 Posted Wednesday at 09:47 PM The TaperLock by its design squeezes down onto the shaft on its full diameter.Properly torqued, should be just fine... 4 Share this post Link to post Share on other sites

What were we talking about again? @mowerman1193- the taperlock hub should work great. As you said just file the high spots and it'll do the trick.

ri702bill 8,577 #23 Posted yesterday at 02:48 PM (edited) Just a note on removal - the hub is shown properly installed, with the outer edge of the bushing flush to the end of the axle. While removing, do not hit the bushing to shock it loose - the jacking apart action slides the hub portion back about 1/8" before coming loose. There MUST be room for it to move..... Look at TaperLock Bushings in McMaster. There are several standard sizes that cover 1" and 1-1/8" Look at the load ratings - impressive. A bonus - works equally well CW or CCW with a reversing shock load.... Edited yesterday at 02:53 PM by ri702bill 2 Share this post Link to post Share on other sites
