Turbo charger pressure pipe FR 500 and FR 600

On the FR 500 and FR 600 with FPT Cursor 13-engine from year of construction 2012 up to and including 2015, the connecting hose for the two charge air pipes is so close to the exhaust gas turbine of the turbocharger, that it regularly breaks due to the enormous heat generated.

Attaching a small heat shield as shown below will permanently solve the problem.

Linkage tensioning lever for fan drive belt

On the earlier "FR" models, the pivot point of the lever for the fan belt tensioner pulley was attached directly to the axis of the fan blade.

The design of this bearing has not proven to be durable, so that in some cases the bearings had to be replaced after only 300 hours of operation.

In the modification shown below, the pivot point in question was moved away from the fan wheel to the already existing traverse of the fan blade, which finally solved the problem.

Center-bolt rear axle attachment FR

There is a certain series of the "FR" that does not have a grease nipple installed on the center-bolt for attaching the rear axle, although high surface pressure and permanent friction occur at this point.

In the long run, this load condition puts so much strain on the center-bolt that it can break without any prior warning!

There is a specific case where a machine lost its rear axle while chopping grass in the field!

The owner of the machine on the following photos retrofitted a grease nipple, which of course means an intervention in the machine's statics. However, it should be considered: some machines have this grease nipple installed at the factory anyway, and a massively wear-out of this bolt is also not beneficial to the machine statics.

At this point, the express note: Retrofitting is carried out exclusively at the risk of the machine owner!

We strongly recommend removing this bolt every 2,000 hours at the latest and checking it for wear!

Attachment grass-header on FR-Series

With the attachment supplied ex works for the 3m grass-header, the harvested crop has to cover a relatively long distance without being actively conveyed, which inevitably results in uneven feeding of the chopper.

To solve this problem, which is also more or less known from other manufacturers, the linkage on the pick-up shown was changed: A 100mm wide rectangular steel-tube was used on the upper cross frame, where the intake-unit lifts the header, so that this change taken on its own, the pick-up would initially have to be raised a little higher, or in the harvesting position the chopping unit would have to lower itself further.

So far, however, this is in no way expedient, since the flow of forage at the outlet of the chopper drum would deteriorate massively. So, to complete this modification, the header's lower locking points were moved significantly forward.

Ultimately, the pick-up was only tilted forward much more steeply and the original mounting height was retained. The improvement in the flow of fodder is now due to the fact that the pick-up is discharged much closer to the feed rollers, making the feeding much more even.

The improvement achieved can already be seen in the significantly shortened transfer plate of the pick-up.

The following pictures show the original condition with the red arrows, the green ones the modification.

Bearing steering knuckle rear axle

As one of the last harvesters, the FR has high-quality roller bearings installed on the rear axle steering knuckles instead of any cheaper plain bearing solutions.

This roller bearing design does not cause any problems and is not dependent on a permanent supply of grease from the central lubrication system.

However, this complex construction has a small disadvantage: This type of bearings is susceptible to water ingress. In order to prevent corrosion and defective bearings here, experienced New Holland drivers retrofit grease nipples here, which are operated after washing the machine to press any water out of the bearings.

Partition net as dust protection

In order to better protect the entire area in front of the radiator packs from dust, which is also thrown up by the front wheels, among other things, this "FR" was fitted with a partition net between the fan and the maintenance space in front of the radiators.

It is simply hung in with hooks and eyelets and can be easily removed again if necessary.


Chute flap FX hydraulically controlled

The older machines of the "FX" series still had the end flap on the chute controlled by an electric motor.

However, as with other manufacturers, this electrical control has not proven very effective, especially due to the low speed. The flap shown on the left in the picture was therefore converted to "hydraulic"; the solenoid valve required for this is supplied by the low-pressure pump (see photo below).

Rotating radiator screen "FX"-series

The rotating radiator screen of the "FX"-harvesters is originally driven by a small electric motor.

After this defect was resolved, this FX-450 was immediately converted to a more robust version with an oil motor.

The oil supply comes from the low-pressure hydraulics.
