howsthat1959 Posted June 11, 2014 Share Posted June 11, 2014 I have tried to find this info via Google with no luck. Just how does the steering gear work on a COE truck? I'm doing a Frieghtliner COE and for the life of me I can't figure out how the steering wheel connects to the steering box (and allows the cab to tilt). Do some trucks have telescoping shafts? Do some have the gear disconnect during a tilt? I've got a pretty good mechanical imagination but I can't figure this out. Thanks Quote Link to comment Share on other sites More sharing options...
Mackvision Posted June 11, 2014 Share Posted June 11, 2014 Most trucks I've seen or driven used a universal joint under the cab,along with a "slip joint" to allow the cab to tilt........................................Mark Quote Link to comment Share on other sites More sharing options...
Mackvision Posted June 11, 2014 Share Posted June 11, 2014 (edited) Kinda hard to see,but here is an F-600 Series Mack C.O.E,you can see the steering shaft extended with the slip joint in the up or tilt position if you click on and enlarge the picture................................Mark Edited June 11, 2014 by Mackvision Quote Link to comment Share on other sites More sharing options...
howsthat1959 Posted June 12, 2014 Author Share Posted June 12, 2014 Thanks for the info. The slip joint makes sense. Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 12, 2014 Share Posted June 12, 2014 yes, the steering shaft telescopes above the u-joint on the steering box on a Freigtiner COE. Shift linkage is chassis mounted and the shift lever goes through a hole in the deck beside the tunnel. Have to make sure the lever aligns with the hole to tilt the cab. Clutch linkage seperates - there is a small frame mounted guide that aligns a fork on the end of the clutch rod with the lever on the pedal below the deck. Most of the air brake control and heater plumbing between the cab and chassis routes around the cab pivot on the passenger side. Sorry, this isn't much detail, but hopefully helps you find more information. Quote Link to comment Share on other sites More sharing options...
