Looking at a HD7 dozer. How hard is it to change the main clutch and also the steering clutches if needed? They also say the hyd is "a little slow" Any ideas. Thanks

on those style monolithic powertrain, it requires pulling engine to replace clutch. if you cant stand on your head and do it through the hole in the floor, the engine has to come out. no experience on steering clutch on a 7 but if if its like a 10, you have to pull the pinion out and move some things around to remove steering clutch. slow hydraulic is probably worn pump but could be too light viscosity of oil.
