Cam 11,5

Cam 410286115 with an angle of 11.5°, made of aluminium, is a drive component of the Kranzle Profi-Jet B line pressure washer pumps – it fits the Profi-Jet B 13/150, Profi-Jet B 170 T and Profi-Jet B 200 T models. Mounted on the pump shaft, with a thrust bearing pack underneath it and the pump housing further down. The rotary motion of the motor turns the cam – its 11.5° angle generates the motion transferred through the bearing onto the pump pistons, converting shaft rotation into their reciprocating movement.

Application

The cam is mounted on the pump shaft of the Profi-Jet B 13/150, Profi-Jet B 170 T and Profi-Jet B 200 T washers. A single 11.5° angle variant covers all three models in this line – meaning the pumps of these models have identical cam assembly geometry and the same piston stroke, differing from each other in other parameters or equipment. The 11.5° angle determines the pump's flow rate and pressure characteristics.

Replaced during cam assembly repair – after identifying wear on the cam surface, damage to the thrust bearing, or as part of a comprehensive pump drive overhaul.

Symptoms – when to replace

• Vibration or irregular pump rhythm not caused by piston seals or valves – suggesting wear of the cam working surface or thrust bearing.
• Visible signs of seizure, scoring or dull wear marks at the contact surface between the cam and the bearing.
• Axial play on the shaft with the cam fitted – wear of the component at the mounting position or in the bearing pack.
• Damage to the thrust bearing combined with signs of heating on the cam – bearing seizure frequently causes secondary damage to the cam surface.
• Corrosion or mechanical damage to the aluminium body – particularly at points of contact with the steel components of the bearing pack in the presence of moisture.

How to select the right part

Identify by reference number 410286115 and the washer model – Profi-Jet B 13/150, Profi-Jet B 170 T or Profi-Jet B 200 T. The 11.5° angle is shared by all three models in this line, confirming interchangeability within them. Do not extend this interchangeability to other Profi-Jet B models without confirming the reference number.

During disassembly, assess the condition of the bearing pack at the same time – both components work together and wear over a similar timeframe.

Compatibility

Cam for the Kranzle Profi-Jet B 13/150, Profi-Jet B 170 T and Profi-Jet B 200 T pressure washer pumps, angle 11.5°, aluminium body. Not a substitute for Profi TST cams (40473 series) or other 41028 series cams. Verify the exact compatibility range by reference number 410286115.

How does the Profi-Jet B line differ from the Profi TST in terms of servicing and part selection?|Profi TST (models Profi 160/175/195 TST) are stationary electric washers with an AM pump (steel swash plate, 40473 series), 18mm plungers and service kits 41.049 1 and 41.748 1. Profi-Jet B is a separate line – with a petrol engine. Service parts for both lines are not interchangeable despite the similar product name. When servicing the Profi-Jet B, always identify parts exclusively by the reference numbers specific to this line.

How to identify early wear of an aluminium cam in Profi-Jet B pumps before noticeable vibration appears?|During disassembly of the bearing pack, examine the cam race in raking light – early aluminium wear appears as a dull, slightly concave surface at the bearing contact point, before distinct scoring develops. Check the thrust bearing rotation by hand – resistance or grating indicates damage to one of the components. Also assess the contact between the aluminium and the steel bearing pack components for galvanic corrosion if there are signs of moisture in the pump housing – in petrol engine washers exposed to varying field conditions, the risk of moisture in the housing is higher than in stationary electric washers.
