Hello All:
THE steering gear on our stock coaches is a 3 1/3 turn gear. (lock to lock). It has an extended end cap and spacer in the Rack cylinder to decrease
the overall stroke to achieve that. The limited stroke is so the lower control arm is not the stop for the end of the steering motion.
I even have a used one I got at Pick and Pull from a 72 3/4 ton that is 3 1/3 turns (not what I would have expected from available information.)
While otherwise regular Trucks that use the same gear have a 4 1/4 turn Rebuilt Gears are readily available for the series if trucks. There is no
way to identify the different applications. (Some 1/2 ton are limited and others are 4 1/4. ) But there is no indication in any listing that
separates the 2 and it is not possible to specify the limited steering box.
Rebuilt steering gears (Cardone 27-7501) do not seem to have a limited stroke and i suspect you might get one by random given that there is no other
difference and it would depend on the core they got. (Unless they machine out the end cap and omit the spacer so they all are 4 1/4 turns)
This may be no surprise to some of you.
Of course I will get responses to change out the Parts: I know that is one solution already. But I would like to avoid that. One reason is that
opening up that gear will VOID any Warrantee. Every adjustment has a Seal on it!
BUT!!!! This coach has a Manny one ton front end kit. I'm suspecting that a 4 1/4 Turn box is no issue in this case.
Can anyone tell me if a 4 1/4 turn box will be a problem with the One ton front end?
HMMMMM??
Regards.
