    Injection Pump timer cover leaking and loose

    Maybe . . . I'm sure if I really literally screwed it up or out that could make a big difference but, as far as I know, the timer mechanism there is to advance the timing under load so little adjustments should be ok. Fuel comes from the feed pump and partly channeled through the timer. Extra...

    Injection Pump timer cover leaking and loose

    According to the manual: "The hydraulic type timer installed in the lower part of the injection pump is operated by the fuel pressure of the pump housing, and movement of the roller ring by the timer advances the injection angle and controls the injection timing." I don't think I can screw...

    Injection Pump timer cover leaking and loose

    Agreed on the pouring out thing. It was just dripping on cold startup. How about backing the adjust screw off another turn or even more? What are the implications of increasing the timer piston stroke? I realize this is probably diesel shop stuff but thanks for any hints! Michael

    Injection Pump timer cover leaking and loose

    I tried tightening the timer adjusting screw up to two turns and the sound seemed to get worse. So I tried backing off a turn (from the original setting) and the sound is definitely is a lot less. Should I back off even more???? According the manual I am adjusting the piston timer stroke...

    Injection Pump timer cover leaking and loose

    Great feedback! How long did you drive yours with the rattle? It's been about 200 kilometers for me.

    Injection Pump timer cover leaking and loose

    Gotcha . . . funny thing though is when I get the rattle I can feel it through the back timer cover way more than the front (which is where the adjusting screw is). I can see the Timer Adjusting Screw (FU-52) is preset to a range (7.5mm - 8mm) so maybe I can try "tightening" it closer to 7.5...

    Injection Pump timer cover leaking and loose

    Hi, Thanks! Looks like that might be the problem. Unfortunately getting access the back timer cover means pulling the pump. I can do that in about a month but what is causing the "rattle"??? No sound cold but once it heats up you get a high pitched vibrating sound between 1200 and 1600...

    Injection Pump timer cover leaking and loose

    Thanks for the feedback. You may be right about the rebuild! 180k on the truck and run with additive since I've had it from 120k. The mechanic would be for pulling the pump and putting it back on. There is a good diesel shop in Cranbrook B.C. which does a lot of mine trucks if I have to get the...

    Injection Pump timer cover leaking and loose

    Hi, 1990 1HZ I had a cold start fuel drip in the winter and it went away with spring so I didn't worry about it too much. It started leaking the first few cool nights of September and, soon after, I started hearing a funny rattle at about 1500 rpm. I put some bio in the fuel and the...

    1PZ seized

    Low oil pressure cut off would cause "seizing" after starting . . . Causes of that could be a number of things from minor to major on the repair scale.

    Replacing electric hubs

    Installation? Hi Guys, Since I'm going to replace my ehubs in the next few days (once the temps drop a little) some instructions would be GREAT. The procedure looks pretty straightforward. You take out the ehub assembly and then attach the Raddapter (tm) and then the manual hub . . . I hope...

    Actual improvement with intercooler

    Hmmmm, good question about the conflicting ic info. Confusing! I am thinking turbo and intercooler for my 1HZ so this is a pretty important point. Some people saying 100 - 200 degree less EGT's and someone else saying it's a no go. . . What's up?

    Headlight gremlins in HJ-60

    Kick me if I'm wrong . . . but I remember a couple of years ago when I lost one bulb . . . both didn't work. Both lights out with just one bulb bad.

    Optima Batteries 24v NFG?

    Same problem for me in my 24 volt HZJ77 . . . my blue tops are bad and this is just the second winter . . . I've been told (by my local elec shop) that the 24 volt charging system is hard on batts and just go with the cheapest with the best warranty.

    Marine/Car and General Battery Questions

    AGM in a 24volt system??????? I second the question . . . I probably have to replace my Optima red tops in the next little while (only 1 1/2 years old) and, though Walmart has just dropped their red top price down a whole lot, it doesn't sound like Optima is the way to go with a 24 volt...

    Marine/Car and General Battery Questions

    Optima Red Top Problem? My red tops are 1 1/2 years old and lately they don't seem to be holding a charge . . . Dual batteries, 24 volt . . . I will check for a parasitic drain but I haven't added anything to the truck in the last few months.

    Clutch Fan - Older Cruiser Weak Link????

    Around 8 bucks per small container . . . I'm told takes about 3 of those to fill an empty clutch fan. But there are different weights and a lot of people think that Toyota's stock weight for North America, 3000 CST, is a little light, especially since stock weight for Australia is 10000 CST...

    Clutch Fan - Older Cruiser Weak Link????

    I think that the clutch fan would probably be fine, as long as it's working. (Big point here) :) But with a fixed fan you don't have to worry about whether it's working or not. Is there a spec for when these fans should be kicking in??? There's a big difference between what Rick says is right...
