Hi all,

I'm looking at ordering a replacement K46HD transaxle for my LT190 directly from Tuff Torq: http://www.tufftorqservices.com/cgi-bin/tts.storefront


I notice they have three different versions to choose from, based on the serial number of the original transaxle:

Select Your Serial Number Range
K46HD 0000001-0011555
(K46HD-JOHN DEERE / 7A646084040)

K46HD 0011556-0012759
(K46HD-JOHN DEERE / 7A646084040)

K46HD 0012760-9999999
(K46HD-JOHN DEERE / 7A646084040)


The price for each choice is basically the same.

I'm confused by this. The JD part number is the same for each of these three choices, which I would think means any one of these would work in any LT190.

My original transaxle has serial number 0002678, so technically I should purchase a replacement from the first range.

But I'm wondering if maybe there have been improvements made in the design in later units, in which case it would be better to order a replacement from the last range.

Any thoughts???

Thanks!

more than likely the differences are somethign minor but may mean older serial numbers need extra parts to make the new one fit. like a different linkage bracket or something.

Thanks, David.

So you'd recommend buying one from the serial number range that matches my original trans, correct?

I would send an email to their tech dept and ask. THey are very knowledgeable and usually answer in a day or two.

Email sent. Thanks for the suggestion.

Day late and a dollar short, but if you have ever dreamed of a diff-lock, you could ask if that option is available to you in a case that would bolt in? You would have to fab a lever, but a diff lock would be sexy.

Wow, talk about customer service!

I got an email reply to my question in less than 5 minutes.

And the answer is, order from the correct serial number range because there could be minor differences in how connections / linkages are set up.

Email sent. Thanks for the suggestion.

I wonder if you could replace a K46 with a K57?

Good luck getting your '90 going again. I guess i should have done your research before diving into my project. :banghead3

I couldn't help but notice those rebuild kits tuff-torq sells for the K46's . Hmmmmmm. Maybe next time around.

Let us know how it all turns out.

That would be great, if possible. I would really prefer to replace the '46 with something more durable.

How would I determine if a K57 would work???

I saw the rebuild kits too. I wonder how hard it is to rebuild a trans?

Given that the price difference is around $300 I might just bite the bullet and buy a new transaxle.

Maybe at some point I'll also buy the rebuild kit. Then (if I'm successful) I'll have a spare transaxle, or maybe sell it to offset the costs.

As far as my 'research', I wish I had started it sooner. I let the local JD dealer pick up my tractor and futz with it for over a week. They replaced the drive and deck belts, soaked me for over $400, and claimed everything was fixed. It wasn't. :crybaby:
