  1. TD18 injection pump issues

    Any thoughts
  2. TD18 injection pump issues

    Hello, so im still working on it as time permits, just reselaed the fuel transfer pump this evening/morning. Installed it on the injection pump and i am still getting the pump to overflow. And i checked the overflow valve and its clean and free, new gasket is positioned correct. i was told on the b model pumps there is two oil drains. Is that correct? If so that is what the rear 90 degree fitting is for. Now i know the transfer pump is not leaking. Where should i start to look next? Plunger return? Sorry for the long post
  3. TD18 injection pump issues

    Howdy, ive hot the engine running good on diesel, the only issue im having is after swapping back to the B pump im not sure how its suppose to be plumbed? None of the manuals i have show a fuel line diagram very well. There is a 90 degree fitting the the rear bottom of the pump (im assuming plunger overflow) that is draining on the ground. Where does this get plumbed into? on a side note he also has a 35 TD40 i decided to get running for him, cleaned the carb and gas primer and jets? Fires off on the second crank now, pulled the injection pump, cleaned it and free'd up the suction checks. Been sitting for at least 25 years. Got it running last night and just got her all cleaned up!
  4. TD18 injection pump issues

    Okay, i found out this pump is not correct, it had a b pump on it from the factory.. and what do you know, the plungers were the only frozen parts in the pump. I swapped the plungers from the A into the B and resealed the pump (didnt touch the transfer pump) installed the injection pump and after bleeding the system it fired off. Does anyone have a schematic or could take a picture of the plumbing for the injection pump? I noticed the fuel delivery is different then the A model.. also where is a good place to get filters? I drained the tank, fresh diesel and ran it through the filters until the fuel was clear and not cloudy. Yet i still dont have good fuel pressure. thanks!

    Good to know Russ! I see how it will be time consuming. and thanks for the advise with a small pipe wrench. ill do some more searching, I know computers seem to pull up more relevant information then phones at times.
  6. TD18 injection pump issues

    Okay soumds good, ill have to hop on my computer, i wasnt getting anything usefull searching the forum on my phone. It is an excessive leak, thats what made me wonder if the pump was fuel cooled/lubed. the gentleman that owns the TD18 also has a shram air compressor that has the same engine so more then likely ill be doing the same with that pump (hopefully not!) my manual should arrive wednesday so ill be able to study the pump a bit more
  7. TD18 injection pump issues

    okay, I am assuming it will say the thickness for the gaskets in the pump manual? the distribution block did not have a gasket on this pump, so I lost you there. yes, that is the seal I am talking about. fuel weeps out between the shaft and what's left of the seal. the transfer pump was pumping quite a bit of fuel out the pump breather, probably a pint to a quart a minute. is it best to just let the distribution block soak in solvent until it frees up? the delivery valves are pretty frozen and without the correct socket I don't want to destroy the splines.
  8. TD18 injection pump issues

    Howdy all, finally finished tearing it apart. Got the fly weights free and they move while rotating the shaft now! I pulled the distrubution block off and free'd up those plungers (in the pump body) but only one is free in the distribution block.. whats the best way to free them up? (Soaking in solvent at the moment) as expected the fuel pump seal is gone, just filling it with solvent it weeps, no pressure needed. Ill just size it up and order a douple lip seal. Whats the best thing to use as a fuel pump gasket? (Between the sections) it seemed like it was a couple thousands thick.. Also the front cover has a giant A on it so im assuming its an A type pump is that correct? thanks again Dalton
  9. TD18 injection pump issues

    Okay that is what I was assuming but with it being full of fuel I wasn't positive. I contacted Central Injection and he said he doesn't have enough to sell out right or a seal kit. so I plan on just sizing up O-rings and giving her a try. Thanks everyone for the help! it is much appreciated

    I just ordered a pump manual. Figured it wouldnt hurt to have one!
  11. TD18 injection pump issues

    Honesltly im not sure, pump number 253701 R92 serial nunber 22759 ive read if the transferpump shaft seal goes out it can fill the pump, also i noticed that if the plunger seals leaked (they fell apart once i pulled the top cover off) it would also fill the pump. How is the pump lubricated?
  12. TD18 injection pump issues

    I plan to disassemble everything besides the governor (making sure all fly weights and shafts are free) the plungers are completely disassembled due to how bad they were frozen. I will give them a call, I appreciate the number! ill try to get a video when i finally get it running. on a side note the fuel in the IP had solidified both plunger screens were plugged from the inside also is the housing suppose to be full of fuel? there is a second "drain" at the top of the housing that isn't going to anything.. it was leaking a lot of fuel (im assuming its a return line and someone swapped a different pump on the tractor, IE A pump on a B tractor or vise versa.
  13. howdy all, I'm working on a friends granddads td 18, I got it running on gasoline and couldn't get it to push any diesel to the injectors. pulled the pump and free'd up the plungers and the rack. now im needing gaskets and O-rings for it. does anyone have a source for some O-rings or maybe a list of sizes? if not I"m going to start sizing up O-rings. I did try calling the shops on the sticky but didn't get anywhere with them.. Thanks Everyone Dalton
