Cat 65/70/75/85/95 Challenger Polyurethane Mid Rollers

Core Charge:

General guidelines for Midroller replacement

• More than 1/3 of the total rubber is missing around the entire midroller
• All the rubber is missing at any point all the way across the midroller
• Any flat spots are seen which may indicate midroller stopped turning

Note: you should always change midrollers & idlers in pairs to promote equal down pressure from the axle to the track.

Preventive maintenance

• Check the condition of the midroller seals. Look for any wet areas that indicate a leaking seal. We recommend using Kile Clear View Caps as they assist you by giving operators the ability to view and maintain proper oil levels.
• Check condition of midroller rubber. Worn or midrollers in poor condition can damage the track if not replaced in a timely fashion.

Wheel Remanufacturing Service:

Want to significantly reduce the cost of replacing mid-rollers & idlers?

Contact D & J Farm Supply to make arrangements to have your worn midrollers and idlers sent in to be reconditioned with high performance polyurethane.

Once the wheels are received, they will be stripped of all the old rubber compound and the rims will be cleaned and prepaired for the retreading process.

The cleanned wheels will then be retreaded with Agritraxx® high performance polyurethane and shipped back for installation.

Turnaround time can be as little as 6 weeks but could take as long as a few months.

Wheel Reusability Guidelines:
