Forklift engine removal

RBnSC · Nov 21, 2022

Boss has 120 hyster. Engine locked up for lack of oil(operator will probably lose his job). I was wondering if anyone is familiar
with these machines or could tell me where to find information on removing the engine? It is a 4.3 chevrolet. I've worked on
equipment all my adult life. Any help would be appreciated.

I spent most of a 28 year job working on forklifts in a large factory. We only had 1 or 2 hysters. But, by and large, Almost all of them needed the counterweight removed to pull the engine. You need to get the rad out of the way and many times its hidden in the weight. Like any vehicle, its a matter of unbolting the tranny and torque converter, usually a crank driven hyd pump on the other end and lifting straight up. Need to support the the tranny with jack or hanger.

I think you are right about removing the counter weight. I had a heck of a time replacing the clutch in the one I have. I did it without removing the motor. Stan

Hi,
I'm Hyster fleet mechanic.Normally you don't need to pull the counter weight.About what year is that 120?Generally speaking you want to get the truck off the ground about two feet,make sure it's blocked safely.Pull floorboards and seat/hood assembly.Basically straight forward from there...much the same as pulling a 4.3 from a car or truck.Depending on year there might be a driveshaft mounted to front of crank that drives hydraulic pump but again pretty straight forward.Matter of unhooking battery,exhaust,wiring,hoses,drain coolant etc...if it runs on propane be carefull unhooking fuel line chances are it'll be under pressure.Engine to trans or trans adapter bolts and either four or six torque converter bolts.Over head crane works best for pulling engine but a cherry picker will work.If it has rops then you can work around and thru it.If cab remove doors or tie them back.Can pull engine hanging a come along from rops or around cab roof and then fly the load out either side of truck.Here in my shop can have engine out in about six hours working by myself.Hope this helps.

If its anything like our old 110, the mechanic here just pullede the guard and seat/cover off of ours and had the engine out in I guess around 4 - 5 hours. I didnt see the whole process, I just helped lift the guard off with one of my lifts.

Radiator,counter weight and overhead guard stay on.Run a bar through the hook of a come along or chain hoist(preferred) and crossways over the top of the over head guard for a pick point...bar will be well supported sitting on top of overhead guard.You will have enough room to pull engine this way.When engine clears the engine bay you can use another truck or a cherry picker to fly the load out either side of truck.
