Super hard to get NP203 into 4 Hi, 4 Hi LOC is easy though

[goathearder]

Hey Guys,
I am having a VERY VERY VERY hard time getting my 73 into regular 4 Hi. I takes about 20 attempts to get it to grab and it makes some seriously nasty sounds when it does. The weird thing is that if I just pull all the way back it goes into 4 Hi LOC with absolutely no issues. I can also geting into 4 lo and 4 lo LOC with 0 issues as well.

Could this just be an adjustment issue? If so, what should I look at adjusting?

Keep in mind that I can get it into 4 Hi, its just very difficult. I am hoping this is a common issue with an easy solution.

Thanks,
John

do you have lockout hubs or the drive flanges?

my bet is the shifter. Mine sucked all the time. pull the shifter boot off and pull the shift levers off. try to click them manually. If they go in then your shifter is the culprit.

There is a way to adjust them, i just opted to do this. http://www.4xfanatics.com/forums/showthread.php?1883-np203-homemade-twinstick

Its totally stock so I am guessing drive flanges. There isn't a lever or switch on the hub or anything.

Dang, that twin stick build is pretty cool! When I can get out to some junkyards I will look for a second shifter and give that a shot. For the time being, I will take the shifter off and see what I can make of it. I didn't know there were two levers.

Well, for the time being I found this nice little picture and description of how to adjust the linkage. I am going to try this tomorrow and I am pretty sure it will fix my problem for until I can do the twin stick build.

Where are people getting extra shifter assemblies??? From the junkyard? I couldn't find a single one on ebay.

Well I am happy to report that adjustment worked like a charm! I have all 5 slots now and no more bucking in low speed turns!!!

I can't wait to make a dual shifter so its even better!
