Forklift Heat exchangers..help!
My Baker/Linde forklift has been down for a while...and Im needing to
get it running again. Historically..I could start it..it would run for a few seconds..and if I waited a minute or so..it would then start and keep running. Now its gone goofy. I pulled down the carby, cleaned it, checked it..it appears fine. Seals are ok, no leaks and if I shoot starting fluid in it..it starts fine. So I then pulled the heat exchanger unit, pulled it down, cleaned it, checked the seals..no problems found. I reinstalled everything and it still doesnt want to run. If I press and hold the primer button on the heat exchanger..Impco Mod J..it seems to run fine. The Carby is a Impco CA-50. Damned thing is driving me nuts. The exchanger is supposed to take the 180psi from the tank and drop it down to a couple pounds and deliver that to the carby. There are two hoses from the carby to the exchanger..a small one..which apparently is supposed to be either a vaccum line..which when the carby starts sucking...is supposed to open something in the exchanger and allow fuel to flow through the big hose. I suck or blow on the small hose..and nothing seems to be happening. Anyone want to give me the poor mans school on what I have..how its supposed to work and some suggestions on what to check? Gunner "The ruling class doesn't care about public safety. Having made it very difficult for States and localities to police themselves, having left ordinary citizens with no choice but to protect themselves as best they can, they now try to take our guns away. In fact they blame us and our guns for crime. This is so wrong that it cannot be an honest mistake." Malcolm Wallop former U.S. Sen. (R-WY) |

Forklift Heat exchangers..help!
Fuel, air, fire...
After that, if gets a bit more complicated... Does sound like fuel tho, doesn't it? Linde: http://www.lmh-na.com/service.php Diesel? You bled the fuel lines correctly? Or Propane? Conversion document http://www.tulsagastech.com/documents/forkman.pdf Model 30 Parts manual - mayby? http://www.urmediazone.com/signup?sf=search_books&ref=4712591&q=linde_h30_for klift_parts_manual.zip This one you have to sign-up for.

Most likely you have to disassemble, clean, and replace membranes and seals. They are easily available. i |

In fact they blame us and our guns for crime. This is so wrong that it cannot be an honest mistake." Malcolm Wallop former U.S. Sen. (R-WY) Your "heat exchanger" is actually a combination evaporator/demand regulator and converts liquid propane to gas at just under atmospheric presure when the sense line indicates demand. If sucking on the sense line does not cause propane to flow something is wrong in the regulator. You are going to need to have it rebuilt or replace it. If you are brave you can look at http://www.teecoproducts.com/catalog...J%20Series.pdf and see a breakdown and all the part numbers to try to fix it yourself - but I wouldn't reccomend it. Troubleshooting info at http://altenergy.rrc.state.tx.us/com...mpcosystem.pdf. My suspicion is someone ran the tank empty, then put on a new tank and opened the valve too fast - bending the valve in the primary regulator, Electric shut-off valve or VFF30 vacuum valve? The VFF30 is better. Likely damaging the diaphragm too. Needs a kit, at the very least. Better yet, replace the model J with a Cobra. The Cobra isn't bulletproof, but it is more reliable than the old J or JB. There is a 1/8* pipe plug you can remove and install a primary pressure guage - should read about 1.5psi not running and .5 to 1.5 running. ##On-Vehicle Pressure Test Shut off fuel supply at fuel storage container and run engine out of fuel. Remove the primary test port plug (see diagram). Connect the ITK-1, 0-5 psi gauge to the primary test port.•Remove secondary test port plug. Install the ITK-1, 0-10 inch wc (water column) gauge. Slowly open fuel storage container valve. Start engine. Note gauge pressure readings. Primary pressure should be approximately 1.5 psi. Secondary pressure on regulators with a blue spring should be negative 1.5 wc. Secondary pressure on regulators with an orange spring should be negative 0.5 wc. Flip throttle several times then allow engine to idle. Gauge readings will fluctuate and then should return to normal as engine idles andpressures stabilize. If pressure readings differ from those stated above the regulator should bedisassembled and inspected ##Regulator Disassembly, Inspection and Cleaning Shut off fuel supply at fuel storage container and run engine out of fuel. Disconnect fuel inlet and outlet lines. Drain cooling system or clamp hoses. Remove regulator. Disassemble regulator•Clean primary and secondary valves with soap and warm water and inspect forwear. Replace if required Clean primary and secondary diaphragms with soap and warm water and inspectfor wear. Inspect primary diaphragm lever for straightness. Replace if required. Always replace the coolant chamber gasket. Clean regulator castings with parts cleaning solvent and inspect. It is very rare forthe castings to require replacement. Reassemble regulator. Use an anti-sieze compound on screws. Use an approved pipe sealant on fittings. Bench test regulatorRegulator Bench Test Remove the primary test port plug. Connect the ITK-1, 0-5 psi gauge to the primary test port. Connect compressed air to the fuel inlet. Pressurize the regulator. Note reading on pressure gauge. Gauge reading should be approximately 1.5 psi. There should be no air escaping from the regulator outlet. If air is escaping from the regulator outlet check the secondary diaphragm,secondary valve and seat. Slowly push primer button several times and release. Gauge will fluctuate but should return to approximately 1.5 psi. |
