Shimming injectors to help cold starts.

I try shimming my injectors to help with cold starts after checking all the usual suspects. Truck was moody in 60 degree weather. Plugging it in was the only way to help and that seemed like oil thickness issue.

[@terrypurviance2513]

Awesome tutorial. I wasn't aware that drilling the spacer plate would be so helpful

[@bayoudiesel]

This has helped me with a few that are moody. Getting that thick oil out really helps the cold start issues. Appreciate the comment and thanks for watching.

I am just getting ready to shim my 97 7.3 and seen your video. I am amazed at the extra half-moon at the bottom of the spacer. Excellent idea. I am going to do mine as well. Thank you so much for your videos I a new subscriber.

I really appreciate the comments and am always glad to hear the you guys are getting something outta the videos be it help or entertainment. We’ll keep them coming. Thanks for watchin.

Your welcome. Thanks for giving your valuable time to my channel.

[@geraldhawkins2643]

Man!! That was a great video, I wished I would of known about this last week just put new injectors in mine but I did keep my old injectors and I'm gonna order the shims for my old ones and drill like you did thanks for the awesome video I did subscribe

[@bayoudiesel]

I appreciate you giving my channel your time. And thank you much for the subscription.

I don't have stock injectors. I'm assuming that it's the same for the injectors that I have. I've been putting this off for two Winters now. The shim kit's been sitting in the top of my toolbox I definitely ain't going through another winter without doing this. I've been plugging it in in the Sub-Zero winter up here in Buffalo New York. It won't even start with 1540 I've got to put full synthetic T6 10w30. You definitely covered the confusing part for me with the difference in shim sizes between Armature Sims and magnet shims. I used to live down in Charlotte I sure do miss the South man. never really had this problem down there. thanks for the vid.very helpful

[@bayoudiesel]

Hey bud. Thanks for the comments and for giving my channel some of your time. I have done this to a few 7.3’s now and have been very pleased with the results. Some of these trucks were having trouble 65 degree weather and had to be plugged. My assumption is that when ever plugging the Block heater in helps then it’s an oil problem. Shimming deals with wear in the injector travel and drilling the drain in the spacer plate helps evacuate oil so it doesn’t stay under the armature plate. That thick oil when cold limits travel also.

I have a DT 466 and it won't start in warm weather but starts fine in cold weather. It is lazy on a hard pull until you keep it wound up for a few miles. Replaced inj and orings, HPOP, regulator and sensor. I will check my shims. Thank you Rod Shelley

[@bayoudiesel]

I hope my info helps. I don’t have much knowledge on the DT 466

[@michaellatino3057]

Thank you for a great video. This is my next fix

[@bayoudiesel]

Glad you got something out of it. And hope it helps. I’ve had good luck with these shim kits on several trucks. No replacement for new injectors but when ya don’t have $2500 to spend it will get ya down the road till ya do. Tip. Make sure you are squarely on the head of the armature bolt and keep a good bit of down pressure till she breaks loose there ain’t a lot to get the socket on with those. That why I like how the shim kits send torques to replace them with. And drilling the larger drain holes in the spacers is key as well. Feel free to hit me back if ya have any questions. Even before ya start if needed.

[@rickeydriskill1096]

Great video. South Louisiana is like south Mississippi we share the same bi polar weather. Hot one day cold the next. Im in the middle ofva engine build. I will be checking that for sure when i begin swapping things over.

[@bayoudiesel]

Shimming has helped when they give cold start issues in warm weather. Buys ya some time before you have to buy injectors.

[@marcuswyatt5642]

Thanks for this video. I've been kicking around the idea of doing this to my hard starting Louisiana truck. First I've heard of drilling those holes. Seems to be a no Brainer though after watching this. Again, thanks for the video.

[@bayoudiesel]

Glad I could help. I’ve had some that were moody to start even in 60 degree temps. This really helps if u need to shim and when I have injectors out I’ll drill even tho they don’t need shims. Really helped a few of mine out. Let me know if I can help and good luck.

[@marcuswyatt5642]

@@bayoudiesel Mine hard starts at 60 and a little above that. I certainly will let you know. Thanks

[@bayoudiesel]

@@marcuswyatt5642 also check the usual suspects for moody starts. Glow plugs, relay, buzz test ect. As well as the tolerances for shims. You’ll get her dialed in and purring.

[@marcuswyatt5642]

Absolutely, already done all that. All new with a White Rodgers gpr and Motorcraft gp's.

[@bayoudiesel]

@@marcuswyatt5642 good deal. Please let me know how it goes. We may be able to help someone else.

[@drifter9425]

Try 5w40w RotellaT6 mine runs WAY better on it and I actually picked up 2mpg after a while

[@adamwright5235]

I did this to my truck 6 years ago. It wouldn't start in 50 degrees or cooler weather. After the shims, I started it in -13 degree weather. Too bad the damage was already done from ether starting it for 3 years. I am in the process of replacing the pistons now because cylinder #1 piston cracked last winter.

[@bayoudiesel]

I have shimmed a few of mine and have been impressed. The combination of shims and drilling out the drain hole seems to really help the moody starts.

[@rexwilson6598]

Great Video ! Just Subscribed to your channel ! I have to do this to my 450 where did you get your shim kit from ? Thanks Again !

[@rexwilson6598]

watched it again and heard where you got the Kit ! Thanks Again !

[@bayoudiesel]

I picked a couple of shim kits off Amazon. They run around $60 each.

[@bayoudiesel]

Thanks for giving some of your time to my channel. I appreciate it and hope ya got something out of it.

[@StevenCollects]

I've been having cold start issues on my 2001. I assumed it was a glow plug issue. It will not start in cold weather unless plugged in. I do have good oil pressure and when the temps are above 70 degrees it will start up just fine.

[@bayoudiesel]

I have had the same issues with a few 7.3’s. If the injectors have some miles on them I will usually shim them. As you can see in the video part of the shimming process is drilling out larger drain ports in the spacer. My thought process is if it’s hard to start in 60 degrees and plugging it in for an hour makes it start then it on the oil side sense that is the primary thing effected by temp. I’ve had good results on everyone I have done. Feel free to hit me back if ya have any questions and thanks for watchin.

[@StevenCollects]

@bayoudiesel thank you for responding. That's exactly the problem I'm having. I'm here in South Louisiana as well. Don't get many days it won't start but it happens. I'm gonna order a shim kit and give this a try.

[@bayoudiesel]

[@rubengomez7972]

Hello friend, good video, could you help me, how did you loosen the screw on the injector plate?

[@bayoudiesel]

Hey bud. Are u referring to the screw in the armature plate underneath the solenoid?

[@bayoudiesel]

Had to go out to the shop for something and looked at my inverted torques socket set. The socket for the armature plate bolt is an E-5. The shim sets I get on Amazon come with all the tools u need. They are really finicky so u have to be dead straight on them and be pushing down to break them. Hope that’s the info u wanted.

[@thevikingwolfpack836]

If you wanna improve your starting an fuel economy switch to 10 w30 rotella

[@bayoudiesel]

Appreciate the info. I have had some 7.3’s on thinner oil but here in south Louisiana they usually do good on 15-40 Rotella. I have seen more improvement on southern trucks with moody cold starts, some at warm as 60’s, with the shims and especially drilling the larger drain holes.

[@thevikingwolfpack836]

Your starter will like the thinner oil too .

[@chrisallen3741]

What causes the injectors to loose its tolerances

[@bayoudiesel]

Normal wear and tear
