Speedo gear swap.

Ok, I did some searching before posting this. I'm looking to correct my speedometer because I am now reading WAY over what I am actually traveling now that I swapped to 4.11 gears. This means it will look like I am putting on more miles, than I really am, so I want to correct this.

According to several sources I need a 36 tooth gear to bring myself back upto par. However, for the year of my jeep (90) there isn't a 36 tooth gear listed. According to sources ( http://www.jeepforum.com/forum/f12/speedo-gear-250875/ ) This chart is wrong ( http://www.gotjeep.net/speedo.html ), but they list all of the correct part numbers. No 36 tooth gear is listed for a 90. Would I be safe ordering one for a 91-93 jeep since it is still a long shaft gear? Or should I order the short shaft version and swap the plastic gear over to my original shaft?

part # J321 2736 Red 36 tooth speedo gear for 87-90 (long shaft).. it is in the parts manuals for a cherokee.. but i went to a junkyard and found one from an 85 xj with a 242 (i think).. but the 242, 229, 231 take the same gear. simple plug and play.

i must have checked around 20 xjs and i got lucky.. now if you can settle on the speedo being slightly off, a lot of xjs come with a 35 tooth.. i only paid a buck for my speed gear.

Thanks man! Looks like the website just omitted the 36 tooth version. I'll be chatting with my dealer tomorrow to see if they can get it, and what kind of price.

Called the dealer here, and that number has been superceded by part number52068158. About $38, and a week to order it in. Oh well, atleast I will get it eventually

Little more pricy than I would have thought but oh well.

I went to a dealer and 25 bucks and was here in two days. dealer is the best place to get wat you want. open it to make sure its a long or a short whick ever one you need,

Why always me? The things that start out being so simple, always go horribly wrong....

Ok, since you need to order parts in person, I got my father to drop by, and gave him the number 52068158 to give the parts guy. I find out from my father afterwards, that part number corresponds to a green 34 tooth gear! I'm supposed to be getting a RED 36 tooth! $38 is lots of money to spend on a gear that gets me speed 'kinda' close.

Since it is a special order item, I cannot return it. NOTHING is ever as simple as it should be...

i would talk to the manager there.. if they gave you the wrong cross reference #, then they should let you return it. but honestly for $38, i would have just gotten a 35 tooth from the junkyard (they are common) and be of a percent or two.

Did some googling, and aparently the cross reference he gave (and I ordered) is good. It comes out to a 36 tooth red gear. The guy who ordered it thought it was a 34 for some reason, but it looks like I'll be getting the right one afterall.

As for going to the junkyards, I wish. There are zero jeeps of any make in any junkyards in eastern canada. They are immediatly bought up as parts vehicles by other jeepers who are lucky enough to get ahold of a wreck. I may have been able to get one from someone in the local jeep club, but it would be hit or miss.

I paid a bit more, but at least it will be the right part. Also that was canadian dollars, so it is closer to $25US or so.
