Questions about this front idler
Practical guidance for CAT 299C Front Idler. Use the specifications above for the recorded dimensions and references.
What should I inspect around the front idler before replacement?
Check for uneven running-surface wear, bearing play, leakage and damage around the idler guides. Inspect the tensioning assembly and track alignment as directed in the machine service manual; a replacement idler alone may not resolve a damaged guide or tensioner.
Do the OEM references mean this is a genuine machine-manufacturer part?
IPX supplies aftermarket replacement parts. OEM references identify the replacement applications.
Does this front idler include the tensioner assembly?
The product photographs and specifications show the supplied front idler assembly.
Can I use a rear idler in the front position?
Front and rear idlers are listed separately by machine and position. Choose the front-idler listing for a front replacement.
What should I check when the replacement arrives?
Check the delivery for transit damage and keep the packaging until installation. Contact IPX if you need help with your order.
