My brothers new 7.3 6 speed. Got a couple questions



So my brother picked up his first 7.3. CCSB 6 speeds which are hard to find around here let alone for a reasonable price. He picked this up for 8k. Minimal rust for a PA truck (came from TN at some point). It does need glowplugs. Is it worth doing the injector o rings while it's opened up? It seems to run/start perfectly fine when warm. Just stumbles on cold starts without plugging in. Secondly, the clutch pedal has play up top and then it engages way down at the floor. It makes it hard to drive. I don't think this is normal (nothing like my truck) first thought was low fluid which I'll check. Could it be the hydraulics are wearing out and just need the master and slave unit replaced? Thanks

First, a good 6 speed is hard to find anywhere. Second, congrats on finding a great truck. It took us 8 months to find ours, but the wait was well worth it.

Changing glow plugs is much less labor intensive than injector o-rings. If the truck does not need new o-rings, don't fix what isn't broken... Some things should be replaced before failure, but some things should just ride until they are nearing failure. Check on the GPR as well, Stancor makes a great replacement if you want to go better than stock.

Your thoughts on the clutch pedal are dead on. Just start looking at things and see what not be right. Look at the mounting/pivoting pins for the pedal, sometimes they can get worn down and make the pedal "act funny". Fluid and master cylinder would be my next places to look too.

Does the clutch engage and disengage OK despite the pedal acting strange?

Also since you plan on going in there anyways for glow plugs check the torque on the injector hold down bolt since it's right there. If they are below 50 INCH pounds you need to replace the orings. Set the INCH pound torque wrench to 50, and check them all, then just torque them down to 120 INCH pounds.
But first set a FOOT pound torque wrench to 20 FOOT pounds and check the torque on the rocker bolts which uses a 8mm socket. Then you can test your INCH pound torque wrench for the injectors on the rocker bolts right before you snug them down since the injector bolts also use a 8mm.
If you want the motor to run quieter look into doing a hot torque on the injectors to 130 INCH pounds. Basically after VERY carefully torqueing injectors to 130 INCH pounds start the truck without intercooler piping or valve covers and let it run for 40 minutes so the entire engine is at operating temperature, then shut it down and retorque the injectors while it's all hot.

glow plugs; need a thin wall deep well 10mm socket, 14 FOOT pounds

valve covers, 13mm whobble socket 90 INCH pounds

Trucks' a butte, Clark👍..
. Having a handshake myself, I'd start fresh. Remove the master/slave assy and install a new/pre bled system..#pf9021. While your pondering on replacing it, remove the slave from down under. Then, stick a tape measure in there until you hit something. If anything more than 2-3/4in, your clutch fork is bent and/or the plastic pibot is broke too...

. There's mods for the peg on the clutch pedal. I went a shoulder bolt route. Others, use a Heim joint. Until then, Dorman has the "birdcage" plastic connector, to connect the actuating rod to the pedal...

once you see/inspect what/how everything is, its not intimidating

I was going to give input, but these guys all have you going in the right direction. Nice find! I looked all over the country last year for this setup exactly. I ended up settling on an extended cab because a CC was non existent. Let us know how it goes!

Thanks for the input! I did forgot about checking the relay and that would be an easy fix. Also i will first check on the fluid level first and then get under the truck and do some looking around. Its been miserably cold here recently and my garage is full so im not sure when we will get to crawl around and check it out. It rides well and runs well and seems to have more power than i would expect for not being tuned. I guess i dont remember what a stock truck feels like either lol. And i looked for a lot longer than what he did when i bought mine (same truck other than a 2000 and this is an 01). The worst part is he will probably ripping the 6 inch lift off and take it back down 2-3 inches to get closer to where we can haul our gooseneck with it. I guess the lift has only been on for 2000 miles. Oh well, when you find a CCSB 6 speed, you have to jump on it lol

I COMPLETELY agree on the lift removal. They are pointless in so many ways and definitely not conducive to trailer hauling of any serious magnitude.

it will definitely be taken off and sold but I'm just not sure when he will get to it. Especially with the temps around here.
