Hey SeanF
Now while you have those engines down . . . observe with the cylinder heads off if you rotate the engine crank shaft BACKWARDS from top dead center indicated for cyclinder #1 ALL of the pistons will be down enough you would NEVER Have an open valve hit problem. Years evolving past the old doesn’t matter cam in block pushrod types into the dosen’t matter either deep combustion chamber SOHC Vega’s, Pinto’s and Chrysler 2.2/2.5’s did not teach me this either. A 70’s Fiat 124 Syder and a 60’s BMW 1600 sure did.
Then I learned to 90 degree back ALL of the inline fours. 45 degree back the V-6’s and V-8’s automatically BEFORE REMOVING the timing belts/chains for a cylinder head removal. Many DOHC especially once the cam driving stuff is removed will have one of the cams spin forward or backwards under half up lobe pressure bending one of the new small stem multi-valves against one of the up to top of cylinder pistons!!
And on reassembly with crank TDC positioning with always one or more pistons UP you have to be super carefull before cylinder head(s) setting back on of ALL of the camS positionings; and that especially on the DODC’s that they are tool locked and cannot move until the job through timing gear/belts setting and relaese is completley done. Pistons all down you can with installed cylinder head(s) cam repositon and/or install the cams and have oopes safely.
You carefull then the crank forward as late as possible UP to TDC carefully feeling for any problems.
Still a butt squeeezer T-belt setting and then cam and tensioner releasing on known loose cam spinner engines like the Mitsubishi DOHC V-6’s and others.
No degree wheel set up needed for this. 1/4 turn back from the marked TDC with a breaker bar is easy to see/feel. (90 degrees). Then 1/2rd forward of this position towards TDCmovement also easy to see/feel. (subtract 45 degrees from the first 90 degrees). Then 1/3 of the remaining initial distance forward to TDC is good 'nuff. (15 degrees subtracted from the 45 gives the ~30 degree setting)
30 degrees Back from TDC because of the later encountered inline 3 cylinders, narrow 15 degree angle VW 6’s, and the various V-10’s and V-12’s out there!!
So far 30 degree back from TDC BEFORE disassemble seems to cover them all. Confess I have never worked this deep on the flat Suburu and Porche DOHC’s to be able to confirm this. Only on their SOHC flat engines.
Chrysler factory book has you align up to thier cast in marks at an actual 30 degrees AFTER TDC before disassembly to be valve/piston interfiernce safe on thier 2.7 DOHC V-6’s. Ha! Ha! Problem is they do not tell you this is what they were setting you up with thier marks to be doing. First one I disassembled was a locked up unable to turn at all rental car fleet oil filter fall off - 8000 miles on the odometer… Very surprized at engine buildup restore and reassembly with my normal 30 degree back off of the factory marks to see two pistons all of the way up. I’d read the book and fell back to thier procedure and Hand wrote the explain into the paper book for others after me. Tech next to me had NOT read the book and bent valves on his reassembly he found out with a two dead cylinder no-start. Expensive out of his pocket to save his job.
Set up good habits you can do automatically tired, distracted, sunburned, sea-sick recovering (had all of these) will save you a lot of grief. I havn’t done the hangover working for years now - avoidable, really foolish and dangerous. Flu sick, still needing to work duplicates this pretty much exactly. Good, thought out, consitently done habits trumps every single time having to brain power trough every new encounter.
Had a good day at our Maple sugar camp, we have been collecting sap sense monday and bolied maple sap all day and pulled off about 4 gallon of fresh maple syrup, Had a pot of chili on the wood stove for lunch with hot dogs, boiled eggs and home made maple sasafras tea. One of lifes pleasures of country life. I think we have out about 300 taps with 6 gallon bags hanging on trees. Hoping for a good season.
Hi Richard that is a nice little evaporator and sugar camp set up.With real maple syrup running $40-$50 a gallon I dont buy much, but a little goes a long way!!
The maple syrup season doesnt seem as long as it was30 years ago, but it is a lot easier gathering sap with out a foot or more of snow on the ground.
Hey SteveU
Some how I missed your post from 2/8/13 Sorry I had a lot going on. This tear down was for someone else not my stuff this time. LOL
Anyways 98 Isuzu hombre(gasoline powered) 2.2 liter 4cyl pushrod design. (basically a chevy s-10 wannabee) Some have still not learned that it is a bad idea to fill a truck radiator with nasty well water. Nothing will rust and gunk up a cooling system faster rendering it useless. This lack of cooling caused high heat in the engine and blew out the head gasket between cylinders 3/4. Not a bad truck to work on but definitely no where near the engine room in the little Dakota with twice the engine. All back together now running on all 4 cyl. Thanks Sean
For the last few years i’ve been going to Kenya to work on my stove project.We started with a fan assisted stove as a pilot program and have evolved with a natural draft model thats simpiler and easier to fabricate.
Check out our website www.wisdomstoves.org if you want to see updates go to wisdomstoves on facebook.
I have really enjoyed following all the builds going on in this forum and look forward to getting back to mine when i return in April.
BBB-But only in a TLUD for now
The dairy farmer down the road makes round bales off my hay field for me, cheaper to make than square ( we always used square bales before as we board horses ) Still saving up for a tractor so for now I had to rig up a cheap way to get the round bales to the feeder. A pallet, a pair of old downhill skies from a yard sale and some screws. The old 6 wheeler is hard to part with, I’ve had for 15 years and it never let me down. The sled works very well on grass and mud too ! After about a year the skies and pallet are ready to be recylced in wood stove - this is my third edition I got him to bale 4 footers so they are easy to roll and stack. I don’t much care if I see a square bale again !
Been getting some new Honey bee hives ready for the spring splits. I lost one of two hives to the cold weather, hoping my other holds on through these last days of winter. Gave then some sugar water today to help them through.
This time of the year the cattle have found that the grass is greener on the other side of the fence. I have some leased pasture that is near a housing subdivision. The lawns are very nice but to the cows they look like the perfect pasture. Most of the people that live in the homes are folks that moved out of Birmingham and think if a cow walks across a lawn it justifies a 911 emergency.
Son and I were able to get the cattle back in the fence and caught about half of them and will try for the others tomorrow morning.
If the cattle get back on those nice lawns they will have to walk 10-12 miles to do it.
Sorry to hear that Wayne. Glad your family and house are okay. Had an ice storm here last night. No damage other than a few downed limb (AKA gasifier fuel).
Sorry mother nature had you in her cross hairs. Hope the hay didn’t get to wet and the wind only pulled the tin off and didn’t do to much damage to the members it was attached to
