Chipper engine speed

[bolla]

Hi I have a Entec 30 DH 1997 Chipper with a Kubota 4 cylinder diesel its the same as a Timberwolf 150

Am trying to find out what RPM the engine should be running at while chipping and how I can check the RPM

The rollers on the entec turn alot slower and they will jam much easier then my mates Timberwolf 150, his Timberwolf sounds to be working at a higher RPM

I would like to check the RPMs on both chippers to compare Is there a reliable method of doing this

Is there any recommendation of what is the ideal working RPM

Thanks

I brought one of these for my crushers. Evertime I replace an engine, i have to set the max revs to 2200 down from the 2600 they are set at. You basically put one of the stickers they give you into the flywheel, then point the laser at it when running to give the rpm.

Not sure what rpm it should run at though. Timberwolf might help

Hi

The manual says that this model machine could be fitted with a number of different model Kubota engines, either the 1205cc 30Hp, 1305cc 30HP, 1305cc 35HP or a 1505cc. The 1505 is the same as the TW150 and they run at 3600RPM.

 

The specification of the roller drive motors on the CH30 may be different to the 150.

Other things to check would be operation of the Direction Control Valve (DCV) To ensure it is moving freely and not sticking which can hinder hydraulic flow.

Ensure all drive belts are tight and in good condition.

 

If you haven't done so already, we recommend contacting your local Timberwolf dealer for technical support for your machine

I have schliesing machines which have Kubota engines, the rpm of the flywheel is important as this is monitored by a proximity sensor which manages to 'no stress' control. Therefore the drive ratio between the engine and flywheel will be the factor that tells you what engine rpm will give an adequate flywheel rpm in order to work effectively and efficiently. We require a flywheel rpm of above circa 1300, but not exceeding this by much.
Non of this may be relevant but I do have a Kubota Series 05 engine workshop manual on pdf if that helps? Let me know and I'll send a copy.
Good luck.
