Maintenance & Repair for MSR WhisperLite™ International Stove

My buddy Ron gave me his old backpacking stove and told me that it leaks white gas and he was never going to use it again. I took the stove figuring what do I have to lose! It might be something simple to fix or worst I just throw it in the trash and call it a day.

I really didn't know what he had given me at first, but after getting home and taking everything out of the stuff sack I saw that he had given me an MSR stove. After doing a little research I found out that he gave me an MSR WhisperLite™ International stove which is a multi-fuel backpacking stove. Four things I liked about the stove right away; proven reliability, rebuildable in the field, multi-fuel, and made in the USA.

Who would have figured a U.S. made backpacking stove! A fair amount of  MSR products about 53% are made in the US and can either be repaired by the user in the field or sent to their downtown Seattle repair shop.

Okay, back to one of the four things I liked about the stove, it's rebuildable! If it's rebuildable then I should be able to get the stove from leaking and working again. There are two service kits available for the stove, the Annual Maintenance Kit, and the Expedition Service Kit. Since I didn't know how old the stove was and the last time it had been service if at all, I selected the expedition kit since it has everything you need and then some. The kit runs about $29.

The MSR WhisperLite ™ stove comes with a fuel pump, windscreen, heat reflector, small parts, instructions book, and stuff sack. I had all the original parts plus two fuel bottles.  I first dumped the old white gas out of the fuel bottle. No idea how long it had been in there. Next, I inspected the bottle for damage which none was found. The MSR bottles that Ron gave me came with Expedition Fuel Bottle Cap. The service kit comes with two O-rings that are used to replace the O-ring on the bottle cap. No more leaking white gas!

There you have it! A stove that was going to be thrown out was able to be saved with a repair kit. It's easy to do and the instructions are easy to follow. But if you don't have the skill or time you can send it in to the MSR repair shop for a fee and they will get you going again.

Always great to rebuild something in the throw away age we live in. Nice job.

On your earlier post about cycling clothes made in the USA. My son is now racing for a team, whose main sponsor does that just that - make cycling and other clothes here in the US:

Cool, eh?
That's cool I will have to check them out
