How many speeds does a New Holland Puma have?
The semi-powershift transmission used in New Holland’s T7 range and Case-IH’s Puma is pretty tough, but it isn’t infallible. The box has six speeds in three ranges – low, medium, high – and it is possible for these range packs to give up the ghost.
What happens when you change your wheel bearings?
As with most types of auto maintenance, you’ll want to take all necessary precautions when changing your vehicle’s wheel bearings to ensure your safety. The worst thing that can happen when changing your wheel bearings is for your vehicle to suddenly shift or roll away. Before you begin, park your vehicle on a level surface.
Why is my New Holland Magnum 340 leaking oil?
A replacement unit was about £225 from New Holland, but he sourced one from Bepco for roughly half the price. Magnum 340s and T8.390s have a nasty habit of leaking oil from the sump gasket. If the sump could be dropped in situ, this would be a straightforward task, but unfortunately it requires the engine to be lifted out.
What causes problems with fan and blower bearings?
Many common problems are caused by the improper selection of pillow block housings, seals, bearings, lubricant, and lubrication systems. Mountings or pillow blocks are available for most types of rolling element bearings.
What causes the bearing on a fan to grow axially?
When a shaft is rotating at high speed, it develops heat, causing it to grow axially. This axial growth places a load on both bearings if they are fixed in their housings. It is advisable to fix the bearing closest to the drive coupling or belt.
How can I tell if my fan bearing is unloaded?
Verify that the bearing is unloaded by rotating the bearing’s outer ring manually; it should easily turn within the housing bore. Once the bearing has been driven a certain distance up the adapter sleeve, lower the shaft to take another bearing clearance measurement.
What should the bearing be on an induced draft fan?
This measurement can be confirmed by using a feeler gauge. The fan’s DE thrust bearing must be fixed in place rigidly in axial direction, with no more than 0.003-in (0.075-mm) axial clearance allowed. Otherwise, the fan impeller forces will push the shaft hard against the NDE bearing and damage it.
