Combo guns, as a generic term, usually refer to shoulder-fired guns that feature a combination of two or more barrels that fire a shot charge through one and a bullet through the other.
How To Rebuild 22R
The concept is an old one, originating in Europe, where the wealthy classes could afford the extra costs of a two-barreled gun that doubled its hunting utility by allowing it to chase either a stag or a bird on the same hunt as the opportunities presented themselves. Landed gentry, without the restrictions imposed by the modern day hunting seasons we deal with today, could and did hunt anything they wanted to—any time they wanted to, on their own extensive estates. Eventually, the idea caught on here in the U.
Tracing its roots back to the Model 24 inthe Savage combo gun has been gone from the lineup for a while, but in late Savage brought the concept back in the form of the new Model 42, a lightweight adaptation with inch barrels and black synthetic furniture that should draw interest among those who like a trim long gun for small-game uses in either a camp or trail gun role. Chambered in. Pull back on that lever with your trigger finger to unlock the action, and the forward barrel section swings down to expose the chamber mouths.
Load the chambers, and the barrels swing back up to their locked firing position. You have to manually cock the hammer each time for firing, regardless of what you do with the hinged action, and Savage has included an additional safety feature in the Model 42 to resist any unintentional discharges as a result of mishandling.
Extraction is also totally independent of the action opening; in line with the no-frills utility theme of the Model 42, the extractor is actually a two-piece assembly with one single stamped-sheet-steel part attached to the polymer sliding manual extractor body and bent to engage both the rimfire case rim above and the shotshell rim below when pulled to the rear by the thumb and forefinger.
Up on top, the little Savage is fitted with black polymer sights. The rear notch is small and tight, but it works with the front blade for a decent sight picture.
The instruction manual that comes with the Model 42 indicates the factory sets its sights at yards. The trigger was a trifle heavy at 5.
The Savage Model 42 is no target rifle, with single-projectile rimfire loads printing fully 8 inches high at 50 yards, and slugs impacting higher, with the rear sight at its lowest elevation setting.
Think Skinner- or Williams-type peep sights. The sight system aside, the rifle did pull off a best-of-session 0. One advantage of the single-shot, break-action design of the combo gun is that, in this case, it allows more versatility in shell length.
Where other action types may limit you to the shorter 2. I also tested two types of. The stamped-steel extractor worked every time on the rimfire empties but failed to engage several of the shotshell rims.
The top barrel is chambered for.If you are rebuilding a 22RE or any variant thereof, including the RET this rebuild guide will be very similar but of course vary whether or not your motor is EFI or carb. We will be swapping a 20R head to increase compression ratio and make best use of our project that will weigh less than lbs. Now with the valve cover free of any nuts, you should be able to gently pry up and remove.
Use a deadblow hammer if you must, but the valve cover should come off relatively easy unless you overheated your 22R. The next step in our how to rebuild 22R is to remove the 17mm head bolts that run through your 22R valvetrain tray and into the engine block.
Now that you have all 10 cylinder bolts loosened, you can lift up on the rocker arm try to remove the entire 22R assembly. You should now be faced with your cylinder head and camshaft as shown above. Begin by removing all the engine mounts and accessories such as the intake manifold and exhaust manifold, if you have not already done so.
You should have the left side of your 22R engine completely clear, mostly so that you can access the water pump bolts. With this air conditioning bracketry removed, you can now remove the 22R water pump by removing the 12mm bolts that secure it. Once you remove the water pump, allow to dry and then clean the surface of the block with a razor blade. When prepping to install your new water pump, make sure to properly clean your 22R surface and use the right gasket.
Now lets go ahead and remove the crank pulley, this can be tricky because of the multiple keyways in the crank snout of the 22R. Now remove the 14mm bolts that attach the oil pump assembly through the crankshaft snout.
Make sure to take care not to damage or hammer the oil pump assembly. Remove the oil pump and flip over to inspect the oil pump drive gears. If you need to know how to test your 22R oil pump, check our How To here. Make sure you get the right part, many times this oil pump can come bare, without the right front main seal and without the relief valve internals. Take this time now to remove the second keyway, which is responsible for your oil pump drive gear. This is hideaway 12mm bolt number 1, located near the water neck and right by your oil dipstick.
Now remove the 19mm bolt that runs through your camshaft, take care not to lose the distributor gear. Our early 22R has the nice dual row timing chain, as well as the metal chain guides. Remove this 19mm bolt and you can now remove the camshaft drive gear as well as the distributor gear. Now with this cam bolt removed, you can turn your attention to your front engine cover. Slide the timing chain off your 22R engine, and then gently remove your cam gear. You should now have enough clearance to remove the 14mm bolt that runs through the front of the engine cover.
Remove the entire front engine cover, and you should now be able to see your chain tensioner and timing chain as well as the guides. These 22R chain tensioners can wear over time, leading to more and more deflection of your timing chain. Remove this tensioner and discard it. Never re-use your chain tensioner, always replace with a new unit.
Gently lift your cylinder head up and off the engine block.
Use a razor blade to clean the shortblock mating surface to prepare for your new 22R cylinder head gasket. After cleaning the surface of your shortblock, you can flip your 22R engine over and remove the engine oil pan, windage tray and oil pickup.Whether it's for street use or competitive drag racing this is the kit to maximize the horsepower of the Toyota 22 engine. The LC Engineering's High Boost Turbo Kit is designed for use with a stand alone engine management system such as the Haltech System or any tunable stand-alone engine management.
The Haltech ECU can be programmed to provide the correct fuel and ignition curve for a performance turbo engine. For this high-boost setup, we highly recommend your engine is set up to handle boost before adding a turbocharger kit. Lower compression or less is the biggest factor. All pipes are ceramic coated for great looks and lower underhood temperatures.
Comes with fittings to add to Oil feed and drain lines. See Part for the kit that is designed for Factory Turbo Blocks. Check out LCEngineering.

R22 Toyota.Started by oddball Parts Wanted. Started by oddball Parts For Sale. Started by GaJoker Engine. MCR19 Registration is now open! Click for event thread. This board has had a lot of talk about this over the years so I thought Id share my experience. I acquired an engine from a friend with the intent of using it for a replacement for my tired 22RE in my 86' Toyota 4x4.
The engine had a propane turbo setup on it, and I was not familiar with Toyota 4 cylinders.
Apon closer inspection after removing the turbo manifold, I noticed a difference in intake port shape. Thinking it had to be compatible with EFI I started to do a little research.
Research told me its a 20R head, And they are not compatible with stock EFI under normal circumstances. Yes it has been done, I found DOAs welded head, and pics of a adapter that were so so, with no explanation.
They arent where you need them. The most important being for the thermostat housing. Estimating the sq in of the EFI manifold passage I knew the 20R passage would need to be made as big as possible within the constraints of the boss width and height. This passage in a blind hole in the 20R head meaning it goes nowhere. Some of the manifold bolts line up, some have to be countersunk, and some tapped.
The details of my engine are 84'?
Pro Turbo Kit
It runs good but I thought it lacked bottom end so I checked the cam, turns out its retarded 2. Timing its 5 jumped, Weird thing is it goes to 40 at RPM no matter where you put the inital setting. I read somewhere this was a ECM problem. Well that is interesting.Deck height of the block was decreased to The decrease in height is only 14mm so it can at times be difficult to spot the difference between the early and late blocks even when side by side.
The single roller timing set up remained but the shorter block required shorter guides and timing chain. The links on the timing chain were reduced from 98 links to 96 links. Many other changes were made and Toyota stuck with the design from thru to the end of production in The E seen on the end of the engine classification signifies that the engine has electronic fuel injection instead of being carbureted.
The turbo included its own cylinder head design with a larger chamber than that of the kidney shaped chamber of the Late 22R but smaller than that of the Early 22R. For the turbocharger an oil drain back hole and oil pressure feed were added to the 22R turbo block on the left side.
The Toyota 22R turbo engine is not a common engine and when it comes time to replace the head a new one can be close to impossible to locate, however, we here at NW TeamYota, carry a new 22R turbo head castings and take pride in providing this hard to find part for your Toyota needs. All new cylinder head castings are available through our parts store at YotaShop.
Turbo oil pump must be matched with turbo timing cover that has extra hole to match. High volume is not the same as high pressure. This will NOT raise your oil pressure, it will increase volume. If you have low oil pressure that is a sign of other problems. Combustion chamber is cc Aplications: Pickup - 98 4Runner - The block is hot tanked, surfaced, and torque plate bored and honed. Head bolt holes are tapped out to ensure proper torque readings.
New freeze plugs installed. Crankshaft is turned to next size. Crank is installed with TaiHo O. Connecting rods are re-sized on large end, cleaned, honed, re-bushed with new pistons and pins. All bearing clearances are measured and documented on a build sheet. Ring end gaps are all checked and recorded. Rebuilt engines have the block hot tanked, surfaced, and torque plate bored and honed. Connecting rods re-sized on large end, cleaned, honed, re-bushed with new pistons and pins.
Installed timing set is O. Includes new timing chain, tensioner, sprockets, and guides. Japanese head gasket with new head bolts. Rocker shafts and arms are replaced with new arms and shafts.
Oil pump is new Aisin O. With correct carburetion and exhaust HP can be achieved. This does now work with 22R engines or turbo applications. High Compression engines require octane fuel. Engines are built differently for different applications, if you plan to use this engine for race application let us know.

The Toyota Pickup really got an increase in performance for the years. The version came with a 2. These 2 type engines are almost identical except for the fuel pump mounted on the cylinder head and the intake. This style 22R motor was also used in the Toyota Celica. It was a re-design from the earlier 22R used from This 22R motor had a different deck height and more important an upgraded cylinder head.
The result was a different stroke and better fuel flow.
Toyota used this version of the 22RE engine exclusively in the truck line after This was simply a modified 22RE long block into a turbocharged model. This did not go over well. Toyota should have learned just as other makers like Oldsmobile Cutlass when converted it from gas to diesel. It is best to build an engine for its specific use and tough to modify with any success and any durability.
Starting from the Toyota Truck also had a 3. This was the same engine used in the Toyota 4Runner.22R with 22RE head, RedLine Cams and Cranks
Again, the 3. Some people get the 3VZ 3. The Toyota Truck was offered in a 2 wheel drive and a 4 wheel drive. These 2 type drivetrains came in both automatic and manual shift. The transfer cases for the 22R type were different depending on the engine.
Some has 2 shifters on the transmission and the other type had 1 shifter on the transmission and 1 shifter on the transfer case.Forums New posts Search forums.

1985-1995 Toyota 2.4L 22R & 22RE 4Cyl
Thread starter Hilux Start date Apr 12, Well, thanks to a PO I suspect used brake fluid instead of oil! I'm doing an engine swap with my weekend! I have a couple of questions, some regarding the swap some maybe not. To let you know where I stand I have heard about the swap but when I've asked about some details I'm not getting the answers I need to hear.
Below are some pics one of what I call "crowned" or "crown top" pistons and below it are standard 22RE pistons.
