Colorado B/S Thread

Re: The Colorado BS thread

ya lemme know...stock gears off the light suck but cant beat doing 80+ at 2k rpm :D


Well Mike, the highway driving was awesome. No more downshifting to pass and gain speed. She held at about 75mph just under 3000 rpm's. The only thing that sucks is my speedo is fawked! I was following my parents to Firestone and I looked down and knew there was no way I was doing 85. So I called my Father and asked how fast we were going and we were at 65!:wow:

Yeah the speedo is definitely messed up. It is like 1.15 mph under what the speedo says. So for 30mph on your speedo, you are really going less than 27mph. I found the 39 and 40tooth speedo gear but everywhere I looked it was like $60-$70. Ouch!

37 tooth? WTF?

Right now I need a 40 but am going to get a 39.

Verify it first, check what you have then figure it out then. I called and talked to the guy and I told him 4.56's with 33's and he said according to their chart it was a 37 tooth but to check what you have in the heep first to make sure. Some of the charts on the net are figured with a specific OE tooth count. They used (3) different OE tooth gears in the speedo, so only way to really make sure is to check what you already have.

Hmmm ok.....

I was going off of Yucca-Mans table on his site
 
Re: The Colorado BS thread

Not sure which charts I went off of but I got the 39 tooth part# 52067639 short shaft.

My XJ is a 99' so I'm not sure if that makes a difference but I have 4.56's and 33's and my speedo is dead on with my GPS.

It only takes a second to pull it out though so might as well verify like Skully said. Just make sure you get the o-ring in there correct or it WILL leak and rip the o-ring in half..........
 
Re: The Colorado BS thread

Too bad i need a 37...

That is weird? 33's a 39 and then 35's with the same gears it goes down?

I looked at that chart orignally Frank, but then I found a couple other charts that were different then I found threads on this forum and others talking about they were off etc. When I talk to whoever at Parts mikes he said that is because Jeep used different OE tooth numbers; 940, 970, and a 1000 something. which is why he said check what you already have then figure in at 60 mph the difference in %, and figure 3mph per tooth. Made a lot of sense.................

Churrrrrokeeeees are laak a box-o-chocolaaats: You never know what you got 'till you open it up!

My bud has been building an XJ on a shoestring budget. I've helped him find used parts: Springs, shocks, LCAs, track bar, tires and wheels, shackles, skids, a lunchbox locker, the 4.10 gears out of my parts truck...

Getting those rear gears out didn't go as expected. I told him about a 4-cylinder XJ with manual tranny that I saw in the yard. The rear axle was already on the ground, it should have 4.10s.

He bought it and brought it over. We pulled the cover to find...

...and it has 3.73 gears.

I don't know why I think that's funny.
 
Re: The Colorado BS thread

finally got started on the tire carrier -- D44 hub/spindle/shaft for a hinge ala FrankZ and others unnamed....

cut a slot in the bumper for the base and cooked that 1/2" mother in there, once again testing the ability and duty cycle of my little welder - slow and hot...

Came out pretty well - it will get a gusset underneath tonight (I hope)

Shaft and spindle are now one, and with a little more grinding work will be ready to cook onto the base

maybe next week I can get it actually operational, although I'm also picking up the new trailer axle this weekend, tiling a couple of bathrooms, building a murphy bed... crap, too many friggin projects! :cry::peace::laugh2:
