superih Posted January 31, 2017 Share Posted January 31, 2017 It has been discussed on here before about an aftermarket park brake kit that is way better than OEM, can someone please point me in the right direction? The park brake on the 856 won't hold unless you set it and slowly let off the hydraulic brakes or the park brake just skips, won't stay engaged.

65806 Posted January 31, 2017 Share Posted January 31, 2017 I just did the update on my 806 the kit is available from CIH little over $100 but well worth it. Pretty strait forward installation. Comes with some new linkage pieces and a tough spring. Only semi tough part of installing it was that you need to remove the top cover on range transmission to install that spring. Mine was doing same thing. Just ratchet sounds as it rolled down any type of hill. Now it make one click and that spring engages the lock and it holds good. I can look up the kit part numberin my recipes if you want. Link to comment Share on other sites More sharing options...
Sparky Posted January 31, 2017 Share Posted January 31, 2017 64578C91 is the kit... $173.00. Worth every penny. Travis Link to comment Share on other sites More sharing options...
pete23 Posted January 31, 2017 Share Posted January 31, 2017 A kit is well worth the money HOWEVER, a properly adjusted park lock will hold just a good. The difference is you can't just jam the original one in park as then you bend the linkage and it does not hold. There is a rather simple trick to get it in park that only requires turning the steering wheel and that will move the gears enough to pop into park. It has to have a over center action if properly adjusted. Link to comment Share on other sites More sharing options...
superih Posted February 1, 2017 Author Share Posted February 1, 2017 Many thanks. So all I need to order is that kit part number and a gasket for the range transmission cover? That's it? Link to comment Share on other sites More sharing options...
65806 Posted February 1, 2017 Share Posted February 1, 2017 Yes that's it. Link to comment Share on other sites More sharing options...
dumbfarmer Posted February 1, 2017 Share Posted February 1, 2017 I have the kit on all my tractors except the 1066 hydro. If it gives problems I'll put it on there too. Like Pete says it should work fine without it... but... no matter how many times I would tell my well intentioned helpers how not to use it, I would still get on the tractor sometimes and the lever would be jammed down so tight I could barely lift it. Bent linkage yup. It's a park lock, people not a brake! Link to comment Share on other sites More sharing options...
65806 Posted February 1, 2017 Share Posted February 1, 2017 I think the 1066 had the new style with the spring from the factory. Link to comment Share on other sites More sharing options...

We have two that we converted and one that needs converting so maybe only the later ones did? Link to comment Share on other sites More sharing options...

Our 1066 and 1466 must have something different than the 806. They don't overcenter and lock like the 806 did but they don't have as heavy of a feel to it like the update kit gives you. Not sure I guess. One thing I'm sure of is I like the new kit on the 806. Gives you some feeling of trust that it's not going to just roll away.

leeave96 Posted February 1, 2017 Share Posted February 1, 2017 What is it that this kit fixes/improves? Link to comment Share on other sites More sharing options...
pete23 Posted February 1, 2017 Share Posted February 1, 2017 It is a new locking lever with a heavy spring that all goes under the range transmission cover with some new external linkages also. All it does is allows you to put it into park by compressing the spring and if gear and park pawl are not in alignment, the spring just pops it in when the tractor moves a hair. With the original park lock, those pawl and gear have to align when you engage the park lever. What happens is that when it does not align operators force the lever and that just bends the wimpy linkage so then it will not engage properly to hold tractor.On the original factory park linkage, you have to adjust it so it has a over center action when fully engaged in the park pawl. If you are not all that familiar with how to adjust it, jack up one rear wheel so you can turn wheel by hand . Then when operating tractor, do no force lever into park. If it does not go the gear has to turn a tiny bit to align. Most of the time, just turning the steering wheel back and forth will wiggle that rear of tractor and it will go into park. I preached this for over 50 years now, but still have to adjust, straighten or replace linkages. Link to comment Share on other sites More sharing options...
jass1660 Posted February 1, 2017 Share Posted February 1, 2017 On my 1206 dad must have put an aftermarket linkage on it as the linkage that goes to the cover has a spring inside of it. I believe it is doing the same as the update kit it just was as simple as removing the factory rod and putting this one in. Link to comment Share on other sites More sharing options...

Actually, it's not doing the same as the update kit is, but it does help prevent the park lock linkage from bending, as you can force the lever into park even if the pawl isn't lined up with the gear tooth.

I have one of those on my 806, works okay but if I ever need to pull the range cover for some reason it's getting the park lock update. I found one of those links on a customer tractor that had jam nuts on both ends. That one didn't work as designed. Link to comment Share on other sites More sharing options...
801486 Posted February 2, 2017 Share Posted February 2, 2017 I got the stuff I needed to put the spring loaded park in my 856 from a salvage yard for $65 I think it was. Link to comment Share on other sites More sharing options...
gary1466 Posted February 4, 2017 Share Posted February 4, 2017 Don't miss the step in the kit about removing the upper pin on the lower end of the rod before installing the new spring. Link to comment Share on other sites More sharing options...
65806 Posted February 4, 2017 Share Posted February 4, 2017 I never read the instructions and didn't remove that upper pin. Probably explains why it feels harder to disengage than I thought it should. Dont know if it's worth taking it apart again or not. Link to comment Share on other sites More sharing options...

I'll bet you didn't put the heavy spring on, either....lol Travis Link to comment Share on other sites More sharing options...
65806 Posted February 5, 2017 Share Posted February 5, 2017 Haha. I put the spring on but never took the upper pin out so it's compressing that spring even more . Its like a SUPER park brake now. To use a IH term from old days. Link to comment Share on other sites More sharing options...
