I just got a Kubota l2500dt with a front end loader. The 3 time using it the pump started to smoke,get very hot and now noisy. The pump I need is about $600. The shank for that pump is short and has spines on it. I have found the same pump for about $250 but it has alittle long shank on it. Has anyone or could I make a spacer it's not that much gap and used the longer shank one?
