Before we can reinstall the assembly into the transfer case, we have to prepare the cases for the larger Marlin Crawler gears.
To do this, we'll first clearance the rear case. Using a die grinder or an air-powered cut off wheel with a 2" to 4" cut-off wheel, remove part of the low range oil slinger as shown in the below image.
Additionally, a section of the housing will need to be clearanced as shown below. This section is circled green in the above image for reference.
Finally, the oil slinger located in the front case must also be clearanced in the same manner. Tip: Take extra precautions to protect both housings from debris. For the front case, we used a cardboard cut out to properly fit the housing to minimize the amount of exposure to the case. Afterwards, we sprayed the interior of the case with brake cleaner and used high pressure air to blast out any traces of debris.
