We have a link belt 330lx that intermittently bogs under a load. it will run for a while in the morning then i starts to stall out, then if it sits for a while it will run fine for a short period then do the same thing. we have replaced the electric hp fuel pump and are currently checking to see if it is a line/filter issue or vent issue on the cap. the cold weather seems to effect this problem as we had it last year and swapped a few lines and filters and it fixed it but it also warmed up and through the summer and the last couple of months the machine has been working hard and running fine. when it is bogging down it does not blow any white or black smoke, has anyone else encountered a similar problem?
it's most likely got a in line filter/screen in one of the banjo fittings on the transfer pump screwed into the hollow bolt
Which engine is installed in it. I've seen plenty of Isuzu motors now with electronic issues that the machine manufacturers don't have the factory Isuzu tools for troubleshooting the problems.
There is possibly a screen in the banjo bolt on the transfer pump. There is also a hidden screen/filter in the hydraulic pump compartment. If you stand looking at the pump there is a metal guard to the right side unbolt this guard and find an electric fuel pump and a screen and a filter if I remeber, this system is found in the common rail Isuzu engines which I believe came out new in 2005....TIO
Thanks for all the comments and John C was right it ended up being an electrical issue with the isuzu motor we finally found a mechanic that found it and the link belt dealer just wanted to turn the pump down. He has ran into this problem with other machines that have the common rail fuel system
