Hi guys,
I’m a 60s owner looking at a customers 40 series at my work, and have offered to give my two cents about it since I know these rigs best. (I work in the office at a small JDM van import shop and we usually work on vans) the guys in the shop are in a little over their heads as they don’t know this vehicle well. I’d love to figure out with the help of ih8mud what the issues I list below are over the next couple days and recommend outsourcing the resolution to a cruiser ship etc. ih8mud is my primary arrow in the quiver as of now so here goes nothing:
context: the rig has been driven around town and is spotless from rust, but is running rough and has some suspension issues. I’ll be able to go more in depth with photos and videos tomorrow after my actual inspection, but getting the thread started now as the guys want this rig completed by Thursday and we want to know whether or not it has bigger problems etc.
My experience is limited to my vehicle even though I did a whole engine rebuild and baseline with the knowledge of ih8mud. I’ve got a few questions that have come up upon inspection before I go into either fixing them or referring the customer to a cruiser shop depending on the issue. The actual techs have done their inspection but I’m the second set of eyes even though I have less overall mechanical experience. I suspect a few things are wrong with the rig which I’ll outline.[ If you’ve seen my threads youll see I’m 26 and have spent the last 3 years getting my 60 back on the road so I’m probably now


]. would love some cheat sheet notes to go off of regarding the following:
—what I should look for for vacuum readings? Should the 1F vacuum be the same as the 2F? This is an early 70s 40 series. I was told 15-18 bb for my engine at 5800 ft in elevation where I live.
— Is the fan clutch meant to be stiffer than a 2f and very hard to spin? The one on my 60 spins about 400 times easier. The 40s one creaks and has a ton of friction between it and the belt portion of the clutch (Can send videos tomorrow)
— The techs are swapping the left and right front leaf springs as the rig was sitting cockeyed. I’m not aware of the leaf spring coming in intentionally varying heights and would love input on this ti not waste the shops time and the customers money. I have a feeling they’re off on this cause my 60 didnt appear to have Intentioanlly offset springs.what else could be causing this?
—Is operating temp of about 220 the same on tje 1f and the 2F? (2/3 up the way on the gauge?)
—The rig runs a bit rough and the owner wants us to give our two cents, but the rig is mainly in for suspension work and a power steering upgrade. I’m gunna hook a gauge up tomorrow, check the timing, etc and do a lean drop tune to see if that helps. Is the principle of (advance it to the point where it doesn’t ping uphill apply just like the 60?) — the rig is desmogged—
—What should the top speed approximately be? It’s still carbed with stock tranny etc. We’re at about 5800 feet here in Idaho.
I’m gunna take it for a longer test drive tomorrow, the customer has been driving it around town but I wanna see if it’s hitting around the typical top speed and not overheating first. Hence why I’m asking the metrics above.
Appreciate any input on this to save me some time for our company and the customer (we’re in small town in Idaho and are one of the only shops)
And, I’m also very aware that these questions are researchable elsewhere and asking em on a forum isn’t doing it by the book, but I’ve had great luck with this communities willingness to help and the forums being more helpful in some instances and we’re on a deadline. The other techs have also given it their once over already.
I’m open to think we should outsource certain things depending on what the problem is. The point is I’m the second set of eyes to catch something like a vacuum leak, pinging, running rich etc. which I think I can do with the above metrics.
ALSO, any threads you guys know about that may be helpful about the 1F fj40s and the questions I’ve asked would be awesome.
Happy to send more photos videos tomorrow as well. The rig ideally leaves this Thursday.
TLDR even the smallest of input appreciated. Like I said we are the first and last line of defense in this town when it comes to older rig. Would love to at least figure out the suspension cock eyed issue and determine if the rig is having serious tuning/running problems. I can probably do this if the above questions are answered. As far as fixing them, I would love to know by our deadline of Thursday so we can recommmend to a salt lake crusier shop if need be. Trying to help out a fellow cruiser and I’m sure some of you guys might be willing to answer some stuff in a short period time.
Thanks in advance
Dan
