Hello Mr Badger I can not thank you enough. I have a 214 that I was having fuel issues with. I'd even called around to have one of the local shops fix it for me. But after watching your video I was able to fix it myself. and quite frankly I had given up right before that again thank you. P.S you definitely saved me a lot of money yes SIR ! 😊
Took my fuel pump off my 15 hp koehler today and yep, the top valve had popped out of place a bit. Pushed it back in place with a screwdriver and it worked. Filled fuel filter and away it went. Thanks for the video help !
Great video. You must have had an OEM pump. The two I was working with had cheap plastic baffles inside. The first pump was working but cracked where the fuel line went in. The second one never worked. After watching your video I took them both apart and low and behold the new pump's brass lever thingy was longer and had a different bend. I rebuilt the two pumps into one and viola! Started right up. Thanks for the post!!!
Great to hear Glenn, I had that happen a few times too. Yes, this was an OEM pump that was 27 yrs old and the replacement pump failed in about 6 months. So, I put this one back in and had no issues after I cleaned it .
Excellent and highly useful video. Just fixed my 15.5hp Command fuel pump. Turns out the upper check valve was partially unseated. Pushed it back in and works fine. Hopefully doesn't come loose again. But if it takes another 25 year to come loose that's OK. Some tips I learned: Go easy on the pump bolts - the aluminum mount will strip fairly easy. Just snug it up. The upper fuel stem screws into the pump. Make sure it's snug before remounting it. Mine was loose. Put a little dab of grease on the actuator where the cam rubs to keep it lubed initially.
@@jetzombie Well here is an update and another tip. So my mower died again last week and sure enough it was the pump again. This time one check valve came out fully and the other was loose. They are a press fit. I decided against trying to glue them in. Instead I stuck a small thin strip of tape to the edge of the check valve and pressed them back in. That extra thickness of tape made the fit a lot more snug. I don't expect them to come loose again. I used 2 mil shipping tape as regular scotch tape is probably too thin. If you use that maybe go twice around.
@@jetzombie Thanks, so far so good. I should have mentioned to clean the edge of the check valve with some rubbing alcohol so the tape sticks better. Basically it acts as a shim so you get a tighter fit.
Kohler M18 correct After rebuilding carb still having starting problem. Cranks fine but will not fire I believe due to lack of fuel. This looks like my next step. Can I remove fuel pump top section and leave the lower section with lever arm in the engine? Thanks
I have the same carburetor but it looks completely different on the inside and then the outside could you offer any help? I can send pictures of the difference if you if you think it'll help
Great video. My tractor has 14hp Kohler , I'm not having any issues but I've noticed my fuel filter is always dry. No liquid gas in it. But the tractor runs perfectly and its been on the same tank of gas for many many cuts now. Is the tractor running on vapours due to a fuel pump issue ? Have you seen this before ?
Thank you for the video, the only one like it on youtube. I just pulled my pump off a 20hp magnum Kohler that cranked but would not fire. The pump looks almost like the one you're working on. When I opened the pump, on the diaphragm side, I found a bit of rust on the round flat metal piece, as well as rusty looking material around the diaphragm material. Would you suggest using the MMO to clean this up? Could it be that the pump was seized up and not pumping fuel in?
There are tons of the diaphragm kits on eBay. It appears you need to rotate the diaphragm post 90 degrees as it sits in a keyed slot at the bottom of the post. Unfortunately none of the rebuild kits seem to include the check valves. Fortunately the check valves seem to be pretty sturdy.
Cam inside engine can wear down. New fuel mechanical pump will not solve either. I resorted to bypassing old pump and installed low pressure electric pump. Problem solved.
I've got an old Cub Cadet w/ a Kohler Commander 12.5. I don't know how long it has been sitting (came with the house) but the fuel pump doesn't seem to be drawing fuel. I just ordered a replacement on Amazon, but it looks like maybe I could just take the current one apart and hit it with some carb cleaner and work those plugers to get it working?
If you get it a part and want to clean it, use very little carb cleaner. When I do it most of the time I use marvels mystery oil or wd-40. It keeps from drying out the rubber and causing any damage to the membrane.
T P's thanks for the tip. Unfortunately when I tried to move the plungers, I broke it. The post it rides on was very brittle and snapped. Fortunately I have a new pump on order from amazon. It was pretty inexpensive and is supposed to arrive tomorrow.
@@jetzombie So, I ordered the cheapest pump that looked right on Amazon. Turns out it was slightly different. The inlet and outlet was inline with the lever that rides the cam inside the engine, so I had to unscrew the top and rotate it 90 degrees. Also, the lever arm on the new pump was much straighter than the J shaped arm on the old pump. I used some channel locks and and a big adjustable wrench to bend the arm until it matched the profile of the old pump. My 10 year old has been helping me with this project and he was so excited when we were finally able to make it start! Just need tires and a battery now.
That's great for you and your son to be working together on this project. I've gotten a few off of amazon and eBay, where I had to flip them 180 and or 90 degrees and tweak the arm. just be mindful to check the arm every once in a while for stress cracks, they usually won't happen, but might. Keep me up to date and if you need any more help.
