FAQ

Questions We Hear Every Time

Straight answers — no runaround.

Do you work on Kenworth, Peterbilt, Cummins, and Paccar?
Yes — these are our core specialties. We have deep experience with Kenworth T680, T880, W900, Peterbilt 579, 567, and 389, Cummins ISX, X15, ISL, and L9 engines, and Paccar MX-11 and MX-13. We know these platforms inside and out.
Do you carry parts on your truck?
We carry commonly needed parts and filters for routine service. For larger repairs or specific components, we source parts fast through local suppliers and have them on-site same day or next day in most cases. We'll always confirm parts availability before scheduling.
How quickly can you get to my yard?
We work by scheduled appointment and yard visits — not first-come-first-served. Most customers get scheduled within 1–3 business days. After hours yard calls are available by arrangement for urgent situations that can't wait.
How do purchase orders (POs) work with you?
Simple — get us your PO number before we start work and we'll include it on your itemized invoice. We support net 30 payment terms on approved fleet accounts. We're familiar with fleet billing processes and can work within your existing vendor system.
Are you insured?
Yes. Banks Diesel Repair LLC carries general liability insurance and commercial auto coverage. We can provide a Certificate of Insurance (COI) and W-9 for vendor setup. Most fleets have us set up and approved within 48 hours.
Do you work on ready mix trucks?
Yes — and it's one of our specialties. We service Con-Tech and McNeilus mixer applications including drum drives, hydraulic systems, pumps, charge hoppers, chutes, and water systems. Most mobile mechanics don't touch mixer hydraulics — we do.
What does a service call cost?
Our standard labor rate is $125/hr with a trip fee based on distance from Denver ($85 within 20 miles). Specialist work on Cummins, Paccar, and ready mix systems is $145/hr. Fleet accounts get a contracted rate of $115/hr with no trip fee for regular yard visits. See our full pricing section for flat rate service estimates.
Do you do DOT inspections?
Yes — DOT inspections are available at your yard or fleet location. We can inspect multiple units in a single visit for fleet customers. Inspections are documented and we flag any compliance issues on the spot.
What areas do you serve?
We serve Denver, CO and the surrounding metro area including Aurora, Lakewood, Thornton, Westminster, Arvada, Commerce City, Englewood, Littleton, Brighton, Broomfield, Greeley, Lafayette, Centennial, Castle Rock, and Longmont. For fleet accounts outside this range, contact us — we can discuss coverage for regular scheduled service.
Can you set up a regular maintenance schedule for my fleet?
Absolutely — this is how we prefer to work. We'll set up recurring yard visits around your dispatch schedule, track service intervals across your fleet, and flag issues before they cause downtime. Contact us to discuss a predictive maintenance program for your operation.
