Leather vs rubber pump cups

Coleman stove users have reported that the rubber cup that comes with the modern pump assemblies does not seem to perform as well as the older leather cups. The rubber cup tends to dry out and degrade over time, requiring users to add engine oil to the sides of the cup to maintain functionality.

Leather cups, on the other hand, are preferred by many Coleman stove users, especially those who use their stoves heavily. While the leather cup may be stiffer and more difficult to manoeuvre initially, it can be softened by soaking it in engine oil overnight.

Leather cups can be used as a replacement for the rubber cups in modern pump assemblies. The leather cap will need to be oiled before use and can then be locked into place using the spring clip.

If you are experiencing issues with your Coleman stove pump, you can try twisting the plunger to the side to create friction or adding a small amount of oil to the rubber cup. However, these are only temporary solutions, and you may need to replace the pump cup entirely.

To replace the pump cup, you will need to remove the spring clip, take out the old pump cup and metal plate, and then place the new plastic backup plate onto the plunger shaft. Finally, you can slide the new leather cup into place and lock it by sliding the locking clip back into position.

It is important to note that the process of replacing the pump cup may vary slightly depending on the model of your Coleman stove and the specific pump assembly you are using.

Soaking the leather cup in oil

Neatsfoot oil is a classic choice for soaking leather pump cups. It is important to use this oil sparingly as it can thicken when cold. Other oils such as vegetable oil and used motor oil are not recommended due to their tendency to polymerize and turn into a plastic-like substance, and their high acid content, respectively.

When soaking the leather cup, it is important to ensure that it is fully soaked before attempting to reassemble the pump. The cup will likely be dripping with oil, so it is advisable to have paper napkins or tissues on hand to manage the mess.

Some users have reported that they did not add any extra oil to their leather pump cup and were satisfied with the results. However, the general consensus is that oiling the leather cup improves its performance and longevity.

In addition to soaking the leather cup, it is important to follow the correct procedure for replacing the pump on a Coleman stove. This includes removing the spring clip, pump cup, and metal plate, as well as placing the plastic backup plate on the plunger shaft.

Removing the push nut

To remove the push nut from your Coleman stove, you will need a small flat-tip screwdriver and a wrench.

First, turn your pump upside down to see how the pump cup is attached. You will likely see a thin self-locking "push-on" nut. Place the blade of the small flat-tip screwdriver between the nut and the pump cup. Carefully pry the push nut off the shaft. Be cautious not to damage the pump shaft.

Alternatively, you can use a pair of needle-nose pliers with round, tapering jaws that are about 1/16th of an inch. Fit the tips of the pliers into the notches on the push-on nut and carefully pry it off. This method is safer and reduces the risk of damaging the pump shaft.

If your stove has grills that are secured with nuts and bolts, use a medium flathead screwdriver and a 7/16” wrench to remove them. If they are attached with clips, it is best to leave them alone as they are challenging to remove. Instead, work around this by flexing the grill's arms to free them from the clips.

Using a replacement kit

When using a replacement kit, it is important to first identify the model of your Coleman stove. This information can usually be found on a label inside the lid or legs of the stove. Once you have identified the model, you can choose the appropriate repair kit.

The repair kits typically include all the necessary parts for a successful repair, such as a plunger assembly, pump cap, pump cap clip, push-on nut, and a cushioning spring. In some cases, you may need to purchase additional parts separately, such as a leather pump cup or a metal nut.

To install the replacement kit, follow the instructions provided with the kit. In general, you will need to remove the old pump assembly and replace it with the new one. This may involve disassembling the pump and removing the push nut that holds the pump cup in place. It is important to be careful during this process to avoid damaging the pump cup.

Some users have reported that the repair kits have improved the performance of their stoves, while others have experienced issues with pressure and rough operation. It is recommended to follow the instructions carefully and ensure that all parts are properly fitted and compatible with your stove model.

Compatibility with older models

The Coleman stove plastic pump is compatible with a variety of older models, including lantern and stove models. The pump repair kit is designed specifically for the lantern model 226 and stove models 442 and 550. It includes a plunger assembly, pump cap, pump cap clip, push-on nut, and cushioning spring. This kit has received positive reviews from customers who have successfully repaired their older Coleman stoves and lanterns.

In addition to the models mentioned above, the pump repair kit is also compatible with other older Coleman stove models, such as the Peak 1 model 550-499. While the design may differ slightly from the original pump, it still functions effectively, building pressure and lighting as intended.

For older Coleman stove models that utilise a leather pump cup instead of the modern neoprene or rubber cup, it is possible to replace the plastic cup with a leather one. This modification can improve the performance and longevity of the pump, especially for heavy-duty stove users. However, it requires careful installation and may involve additional steps such as soaking the leather cup in engine oil to soften it before use.

The repair kit is also compatible with a range of other Coleman stove and lantern models, including 222, 229, 400, 440, 445, 3022, and 3024. It is recommended to refer to the model's label to confirm compatibility before purchasing or installing the repair kit. Overall, the Coleman stove plastic pump repair kit offers a viable option for restoring older models to working condition, ensuring uninterrupted outdoor adventures.
