- This is my 1st video in almost 2 years.
In this video I will be continuing with restoring and rebuilding the OM352 engine on my 1973 Unimog 406. I hope you enjoy!
thanx bud. really enjoyed the clinical measurements. cant be too accurate. just spot on
Good work, this is a great level of precision 💪
Very precise work, i enjoyed watching this video and cant wait to see more !
great to see you back !!! love the content !
Thankyou very much!!
London sucks for nice motors. I’ve been working there for a while now and not a fan of all the parking and driving fines! Glad to see you back at it though. Keep the chin up and I’m liking and subscribing as we speak
I know mate, not a place for hobbies that require open space! Thankyou very much 👍🏽👍🏽
Good to see you back on RUclips. Really sorry to hear that ULEZ has forced you to get rid of a vehicle which (especially with you as the owner) would have lasted pretty much forever, sounds like a really environmentally friendly policy to me 🤔
Negativity aside, you’re moving on and keeping yourself busy, you can always build another Land Rover. I had to sell a few vehicles recently and it’s never fun parting with stuff especially when you’ve put so much sweat and blood into them. Power to you mate. Keep up the good work
😂 if only it were 15 years older. You got the nail on the head, it’s all a bit of a scheme!
God willing, one day I will build another one yes and go all out on it. Thankyou very much for your comment 👍🏽
Always "spring pass" your final cut for Boring on a Milling machine. Lathe not so much. bigger bearing set on a lathe. The Mill has centrifugal inertial forces loading on the bearings and boring bar. slowing it down reduces this load. (not necessary for this op or set up, just making a point) FYI nice shop I'm totally Jelly !!!
Thankyou very much mate, yes it’s surprising how much a spring pass or even a few spring passes can remove. It’s hard to demonstrate to people who may not have much experience in machining just how hard it can be to remove that final 0.005mm. @14:25 I had to do a spring pass a couple of times to hit the final dimension.
Thanks for your comment!!
nice work man. Them wrist pin bushings. Are they not made from nickel aluminium bronze vs phosphor bronze? My worry is you custom one might blemish and peen where the wrist pin force pushes on the power stroke. I know these are quite low power engine so may not matter.
Hi mate, Thankyou for very much.
So the bronze I have used isn’t a phosphorus bronze it’s LG2 bronze. The original factory bushings seem to be some form of leaded bronze also but I can’t say for sure.
What I can say is the custom made bushing that was in that rod from the previous rebuilder was the only one of all 6 that was still within spec, all others had become oval due to combustion. That was most definitely an off the shelf bronze and I’m fairly confident it was leaded instead of phosphorus.
The “feel” I got from boring the LG2 bronze in comparison to the factory bushings also gave me the impression that the LG2 would withstand a lot more abuse than the “sheet rolled” factory bushings.
At the end of the day however, it’s all theoretical until this engine has been put through its paces 😂 only time will tell for sure.
I wanted to try the lg2 bronze as I’ve heard of it being used for custom small end bushings and bushings in general before, I could have just ordered a new rod for £100 but I’d never get a solid confirmation on whether or not the LG2. Is a good material (that’s my experimental side).
@KeepitBigBore Oh i see pal. Im sure youll be fine then by the sounds of it. Its a low stressed engine anyway isnt it. Keep up the good work. 👍
That was the other thing as well, I wouldn’t do it on someone else’s engine or any high performance engine of my own. ….. not until I see how this one performs at least 😬
Thankyou for commenting 👍🏽👍🏽
Do you think the unimog is ulez compliant, or you could get a ford focus camouflage cover 😂
I hate this government squeezing every penny out of us and expect us to just keep taking it
I hope it is, there is no going back for me now. I’ve put too much in to it! It HAS to be ULEZ compliant now 😂 could put an om352 generator on the back, put a Tesla motor on the transmission and say it identifies as an EV….
I know it’s crazy, when you see how much we all get scr***d you can’t un see it 🤦🏽♂️
@@KeepitBigBore there's an idea mate you could say the 6 cylinder diesel beast is to charge the ev battery I'm sure they won't flick an eye lid over it 🤣😂
