Hello all, Picked up an 8R on Craigslist and cleaned it up and replaced most of the gaskets, graphite, etc. Has anyone ever seen a Factory pump model? The pump has a riveted holder in the center of the lid that looks factory. Fits between the tank and bell when closing, and even pushes the heat shield against the tank. Ideas on date. From reviewing the forums, it seems a later model. Could be a cold weather model as is from the Pacific Northwest where we snow camp quite a bit. Thx, M
I've never seen an 8R with a bracket for a mini pump, so I think that was added by a previous owner. The mini (and midi) pumps were offered as after market items. They are sometimes available on that auction site, though it looks like you already have one. The pump is not necessary to operate the stove. ....Arch
Pump holders retro-fitted to Op.8R https://classiccampstoves.com/threads/pump-holster.17576/#post-179325 Best Regards, Kerophile.
Thank you for your input. I posted this to see if anyone else had seen a pump fitted similar to mine. The pump mounting clip is formed spring steel and looks very factory. It may have come with the pump, but doesn't look home or shop made. Time will tell if this is a one off or factory. If anyone else has one post pics. WOW, the pumps really inspire strong feelings on the forum. Lots of posts that they are not needed. The old Hunter advertisement seems to think they have a place with increased BTUs and decreased boil times. Will have to wait until next winter's snowshoe backpacking trip to see how it does directly placed on snow. Thanks for all of the helpful information on the forum. The restoration photos are inspirational. Really helps maintaining these old stoves.
I have used an 8r without the mini pump in below zero temps by digging a hole in the snow and placing sticks beneath the stove to elevate it off of the snow...the stove worked fine. The same stove did poorly when used in a lean-to at 30 degrees F...too much heat loss from the tank did not allow it to build up very much pressure. In mild weather, no pump is needed. Once the temperature drops, insulate the stove from the cold ground and use a reflective wind shield...or use to pump. The pump is fun, but not a necessity.
Hi, All, I am one of those that, in Winter, takes a pump along with those of my stove that could possibly use it. The list varies, but just for grins, 8R, 99, A SVEA 123/123R, Ranger #10, 199, #85 Loke, and other such stoves. Sometimes I need it, sometimes I don’t. But, the pump weights very little, and so I take it along. Others may choose not to do so, and that’s great. I made my choice, they made theirs. As to a snap-on place for the pump on a factory 8R, I seriously doubt that happened. I have been at this for a long time, as have many others in CCS, and I’ll wager none of us have ever seen such a think, unless a previous owner had installed it. Just sayin’..... Take care, and God Bless! Every Good Wish, Doc
Hi, let me agree with Doc @Doc Mark . The pump and “Terry” clip are indeed factory made, but they were skilfully brought together by a previous owner. Best Regards, Kerophile.
Neat clip for the pump. A side note - When Norway lifted the ban on petrol stoves some time in the 1990's, the local Optimus distributor introduced the 8R only with midi pump supplied. They were afraid that the lower output compared to 111 and 199 on self-pressure would be a disappointment to the market. Also winter usage played a role. The Optimus denomination was 8RP where "P" stood for pump. But there was no clip, the pump was just supplied with the stove.
