The Caterpillar 248B Skid Loader has three windscreen sections fixed together with structural sealer. It’s certainly not a job for the DIY technician unless you have the glass already pre purchased, or cut to size.
With that in mind we are not going to go into minute detail with the installation. We will assume that you will have enough understanding of the basics that you will not require a step by step.
In this case we cut and processed the windscreens onsite from one of our pre made OE templates. Cutting the right hand shaped windscreen is a challenging job even for an experienced glass cutter, so we will not be discussing the glass cutting and processing in this blog also.
The loader we had to repair had two of the three windscreens damaged. The right hand side and the centre windscreen.

First off we have to remove the windscreens. To make life easy we prefer to use the BTB glass removal system. It takes little effort with the BTB and it speeds things along ten fold. You could do this manually with a Olfa Knife or other manual tool, however, it will test your patience as it makes the job much more difficult.
|Main tools for the job|
The BTB system not only removes the windscreens quickly is also keeps them in one pice. This makes life so much easier as there is minimal clean up. In this case we used and old BTB-W4KS Blade. No need to use a new one as this kind of work does butcher the blade a bit.
|Use OE templates to cut windscreens when possible|

Ok, now we are all good to bond in the windscreens. If you have used OE templates everything should be nice a snug with tight tolerances. The gaps to the middle windscreen should be about 5mm.

The adhesive we use is Sika Drive. It has a one hour drive away time and will be stuck fast in about 10 minutes. As we don’t want to disturb the position of the newly installed windscreens you can now go off and do something else for 10 minutes. We use this time to pack away all of our equipment. By the time we are done, the adhesive has cured enough for use to work on the windscreens without disturbing them.
|Cut a nozzle as wide as the actual gap|
We tend to not pump the sealer right into the gap, but rather just hover the nozzle over the gap. This way the sealer is injected into the gap and on the edges of the glass too.
|Be gentle on the first pass to work in the adhesive|
|Firmly run you finger down the sealed joint|
Remove the tape carefully and all is complete. The more time you spend with your preparation the better the end result will be. The more experience you have with kind of work the better you will get. However, if you take your time there is no reason you can’t get it right first time.
