Finally have no choice but to swap out the Q-trac. The new chain I put in close to a year ago, is starting to jump teeth already. Road driving it is fine, 99% of wheeling it is fine, the 1% when I need to put some mustard on it, not so fine.
When the first chain stretched, I figured with 90some thousand miles, it was just it's time. A cheap Crown replacement lasted literally 4 hours. The brand new Morse lasted almost a year. Add that to the stripped out inner splines of the previous clutch cones, and it's just too much to keep fixing.
It seems it's just not meant for the type of wheeling I like to do.
After searching high and low, and trying to find what I can from anybody that has swapped in a Dana 18, I came up blank. Many people start threads asking about doing it, get advice on swapping everything but what they asked about, and the thread dies with no conclusion.
I've decided to start this thread so maybe somebody else can learn from it. But mostly because I have no idea what I am doing, and will surely have some questions along the way.
Picked up a small bore, 6 spline input, 1.25" intermediate shaft Dana 18 for $100. I know the guy, and trust him. He told me if there was any problems other than normal wear and tear, he'd give me another one.
Opened up the pan. The oil looked kind of funky, but no signs of water. Scraped the bottom of the pan, no signs of metal shavings.
What I really wanted to do was check for wear on the intermediate shaft. It looks fine as far as I can tell, no marks other than what looks like normal bearing marks. As of now I don't plan on replacing it.
Ordered a gasket and seal kit from Novak.
I have some time as Novak is running off the adapters right now. They won't be read to ship for about a week.
So I might as well strip it down and replace all of the gaskets and seals while I am waiting.
First step of the swap.
