I bought an Advance Adapters kit from All-Pro some time ago.
The garage is now fitting it for me & having difficulties.....
I have two transfer boxes, one is a Mk1 pre 1984 ( this is the one we've dismantled ) and the other is a Mk2 to which we're adding the split Mk1 box.
The instructions say to "remove the main gear from the output shaft and fit it to the new intermediate shaft".
Here's the problem... The Mk1's main gear seems to be part of the output shaft & refuses to move despite having had 15,000Kg ( yes - fifteen thousand kilos ) of pressure put on it. There seems to be no seam between the two, it seems to be one piece.
Is the Mk1 a one piece unit ? Should we be using a Mk2 output shaft ?
Also if the Mk2s are 2 seperate pieces how do you press a gear onto the shaft so it takes the drive forces & doesn't spin ?
Any advice, tips & tricks greatly appreciated.
PS
I'm in the UK using UK parts not that I think that matters as it's all Toy at the end of the day.
Ok it is not a one piece unit it can be dismantled no matter what year you have.
There are no differences between the years in the main shaft
I just pressed mine off and yes it took a whole hell of a lot of force, as stated above make sure you removed the snap ring or the bearing will not come off.
Maybe the confusion is that you are not trying to press any gear off, as the gear rides on a caged needle bearing and will slide right off after you press off the output shaft bearing. This bearing is held on by a snap ring. Once the snap ring is removed, you can place the shaft into a press, and by pressing down on the end of the shaft, and supporting the shaft by the main gear, which is not the little gear which is the very end of the shaft, but the big gear next to it. This will not take a whole lot of pressure to remove. The only piece of the output shaft that you are interested in is the big main gear which you will install onto your new little stubby output shaft.
Once you have the main gear on the new shaft, and put the spacer on with the little ball to hold it from spinning, and press the new bearing on after it, then you install the whole thing into the adapter plate, and put the new, very strong snap ring on the end of the new shaft. This is easy with about 4 hands, and a sweet set of snap ring pliars. I broke a set of snap on pliars doing this once. Now I place it in a press, and center the snap ring on the shaft, then apply a small amount of pressure to the snap ring via a large socket. Then I use a screwdriver and lightly tap it down into the groove.
We have a UK DJ that regularly phones the US on his show ( mainly garages ) to ask for help with his car cos the boot's knackered.
It's a word that constantly baffles you yanks.
Getting back to me jam-jar.... I'll let you know if it all goes titsup.
Obviously a bit worried about this gaff as it cost me best part of a pony or was it just a couple of monkeys. Either way the trouble & strife weren't to happy about it.
Garage still havent got back on it yet. Alleging they're gonna have a go Friday. They need a week rest after last time.
What they're saying is.....
They think they have to ghange the input shaft on the receiving t-case rather than the output on the 1st reduction box ??
If only I could find some crawler gears that worked as slow as they do ?
Nah that'd be toooo sloooow !
This was a 2 week project stared over a year ago as a stop gap as the previous 2 week project was started 4 years ago by then & all I have now for it is parts.
How much they charging you by the way? This should be about a 2 hour job for the adapter portion, with some more time for installation, and drive line changes.
Just read this...hope all goes well. Let us know if you have other problems.
They're not just bodging it are they
