oldschool90 Posted February 12, 2014 Report Share Posted February 12, 2014 Hey all, got myself in a bit of a predicament. I've got this forklift at work (we call her Big Alice, because she's got a big ass) and I was giving her a tuneup, and I forgot to mark the plug wires before I took the cap off. Now normally I would have switched them over to the new cap, but I had to take it into Carquest to find a new one. I've tried hooking it up per the l28 motors, but either the rotor at TDC is pointing somewhere else, or the firing order is different. I was hoping someone on here would recognize the motor and be able to help. Pics: This is Big Alice. Truck on the right for reference: Motor pics: Water pump: Under the cap: 1 Quote Link to comment
yellowdatsun Posted February 12, 2014 Report Share Posted February 12, 2014 God luck with finding any parts, that's a Nissan Patrol engine. Getting parts is extremely difficult. Way worse than the 4 cylinders that you usually find in Nissan forklifts. 1 Quote Link to comment
captaingamez Posted February 12, 2014 Report Share Posted February 12, 2014 Hmm, try and see if you can find the firing order for the old Nissan Patrol P engines 1 Quote Link to comment
DanielC Posted February 12, 2014 Report Share Posted February 12, 2014 Pull the valve cover off, turn the engine slowly in it's normal direction, and watch the exhaust valves. The exhaust valve will open, then the intake valve will open, on each cylinder as you rotate the engine. As the engine is rotating, write down the order the valves move. That is your firing order. This works with ANY four stroke cycle engine. 2 Quote Link to comment

ggzilla Posted February 12, 2014 Report Share Posted February 12, 2014 The firing order is 1-5-3-6-2-4, anti-clockwise Quote Link to comment
260zkaboom Posted February 12, 2014 Report Share Posted February 12, 2014 Firing order: 1-5-3-6-2-4Point gap" 0.45-0.55mmDwell angle: 35-41 degreesSpark plug Standard: BP6ES - Gap: 0.8-0.9Turn anti-clockwise. from-----http://patrol4x4.co.za/viewtopic.php?f=48&t=2469 find #1 firing spot by putting your thumb over the #1 plug hole (#1 plug removed, and cap removed), crank over the starter with real quick blips until it 'burps' your thumb away from the hole and turn the key off. Get a socket n ratchet and put the pulley at top dead center. Hook up the plug wires and it should run. Quote Link to comment
260zkaboom Posted February 12, 2014 Report Share Posted February 12, 2014 danielc had a good comment, it works perfectly, and it looks like it needs a new valve cover gasket anyways. I just relearned something i forgot from this. Quote Link to comment
oldschool90 Posted February 13, 2014 Author Report Share Posted February 13, 2014 So I got the wires hooked up today in 1-5-3-6-2-4 order lined up to what I thought was TDC, but no go. Then the damn starter died. (It was already on it's way out, this was the final straw I guess) God luck with finding any parts, that's a Nissan Patrol engine. Getting parts is extremely difficult. Way worse than the 4 cylinders that you usually find in Nissan forklifts. Yay. <_< Pull the valve cover off, turn the engine slowly in it's normal direction, and watch the exhaust valves. The exhaust valve will open, then the intake valve will open, on each cylinder as you rotate the engine. As the engine is rotating, write down the order the valves move. That is your firing order. This works with ANY four stroke cycle engine. I'll have to do this tomorrow. Wow. P series. Interresting It'd be nicer if it was an l28 or something that has more parts availability. .That fan looks wicked, carefull I see nothing wrong with it. The firing order is 1-5-3-6-2-4, anti-clockwise Thanks, I found this right before work. Unfortunately, I don't know where TDC is on the dist. I can't get to the front of the motor very easily and fine tuning crank positioning is gonna be a bitch.

Get a socket n ratchet and put the pulley at top dead center. Hook up the plug wires and it should run. I'm not sure yet how I'm gonna get things lined up yet. I can't get to the front of the motor very easily and I'm pretty sure that even if the markings on the pulley are clean, theres just too much other shit in the way to see it, and fine tuning crank positioning is gonna be a bitch.

ggzilla Posted February 13, 2014 Report Share Posted February 13, 2014 Don't bother pulling the valve cover to try to determine firing order. You already know the firing order. All straight six have the same firing order, but some are clockwise and some anticlockwise. Quote Link to comment
oldschool90 Posted February 13, 2014 Author Report Share Posted February 13, 2014 I still need to figure out where the rotor points to at TDC. Quote Link to comment
ggzilla Posted February 13, 2014 Report Share Posted February 13, 2014 Disconnect coil. Remove #1 spark plug. Put your thumb over the hole and crank until your thumb is blown off. The rotor will be pointing to #1. Quote Link to comment
ratpatrol66 Posted February 14, 2014 Report Share Posted February 14, 2014 The much hiped Nissan forklift with Patrol power really does exist. I read about this so much on Patrol sites years ago with no proof until now! The rotor in pic no.10 down from the top is the same as my 66 Patrol with none water proof dizzie. I don't see points in that diz. If there is a part no. on the diz. ignition module pass it on please! Check for PM. 1 Quote Link to comment
oldschool90 Posted February 17, 2014 Author Report Share Posted February 17, 2014 Hey guys, got it running. Rotor ended up pointing at about 2 o'clock for #1 and the order was 1-5-3-6-2-4, A-C. She's nothing special, but if anyone's interested, I can get a vid of her running. The much hiped Nissan forklift with Patrol power really does exist.

I posted here because it's Nissan powered. The part number is in that pic (39s-v4). There's no other numbers as far as I can tell, but I'll double check, and those wires go straight to the coil.

datzenmike Posted February 17, 2014 Report Share Posted February 17, 2014 There nay be a part number stamped on the side of the dizzy. It will start with 22100-????? Quote Link to comment
