Baffle, Oil Radiator Inlet, Yak 52
Don’t tolerate oil temperature needles in the low caution range when you fly - land and do something about it. Remember, however chilly you feel on the ground, what matters is the temperature of the colder air aloft, blasting across your Oil Radiator at 130 knots.
In combination with the radiator outlet door, this ground-adjustable Oil Radiator blanking plate will keep your Yak’s oil in the green in the coldest months of the South Western US winter.
Further East and into the Midwest, if your oil Temperature needle hasn’t moved into the green during the run up, you can shut down, remove the plate & flatten up to four of the flaps to block even more cold air from entering your Oil Radiator.
Just to get us all on the same page, this ground adjustable baffle plate is designed to be bent once - to find the sweet spot for your Winter conditions, rather than to be adjusted every flight.
How many times can you bend a flap before the material will crack?
And don’t forget to remove this baffle when warmer Springtime weather comes...
Made from 5052-T32 Aluminum, riveted and anodized. Three rubber buffers, screwed to the rear face, prevent damage to the face of the Oil Radiator core.
Yak Instrument Panel green - Color plus Matte Clear Coat aerosol system
Skip the hassle of trying to match 'THAT' green for your new Instrument Panel ....TYC has done a digital color match for you!
This classic, calming shade is PPG's Omni Acrylic Urethane basecoat with integral converter. Links to detailed instructions for its correct application come with purchase.
By itself, this colored basecoat will be very fragile so a Matte Clearcoat ( 2 part- mix in the aerosol) also with instructions, is included.
Color aerosol contains 115 milliliters ( 4 fluid ounces), the Matte Clearcoat contains 400 milliliters.
This product cannot be returned or refunded.
For customers outside the United States, aerosols must be shipped by other methods than by air.
Cylinder Base Nut Wrench, M14-P
When does a tool become...a precision instrument?
You actually know the moment you pick it up.
This wrench is a pattern of the field service tool included in Yak 52 toolboxes. The test of accuracy in reproduction wrench geometry is the cylinder base nut next to the sump, shown here.
But surely adding a half inch drive couldn’t hurt for accurate torque wrenching?
The factory spec for cylinder base nuts is 27.5 ft lbs ( Source: Termikas engine manual) but an informal survey we made of several well-respected Yak mechanics suggests many people are using closer to 45 ft lbs - the value for Lycoming cylinder base nuts. We tested this wrench to failure at beyond double that value.
Will you be able to break yours ?
If that’s what you set out to do, then certainly.
But if you treat this instrument with the same care as the other tools in your toolbox, then most likely it will neither break nor the socket’s 12 points become dull.
Not going to lie, we went down the Rabbit hole with metallurgy and heat treating on this one.
Want us to go into all the blah blah blah about grain structure and Brinell Hardness?
No, of course you don’t
You’ve already got a drawer-full of busted Chinese ones.
The Yak Collection - tools for a lifetime
Yak 50 / CJ Cooling Gill Louver Axle rework kit
This kit includes a re-usable plastic drill bushing template (plus three steel bushings with lock nuts) to repair Cooling Gills that have excessive movement because of wear in their axle support holes.
This template will accurately locate the center of the Gill Vane Axle before damage occurred.
After removing several Gills either side of the damaged location, lock your template in position.
Do this by pressing two of the short M4 Gill Vane Positioning Screws you just removed through the two smaller holes in the template and into aligned holes beneath.
A fence molded in to the template ensures correct edge distance.
These hardened drill bushings will keep your 5/16” diameter drill bit centered and on a true perpendicular axis. Remember to remove material with the least drill pressure required because the plastic template may soften if excess heat is generated.
Insert the hex head of the new axle support bushing next to the lower end of the Gill Vane and secure the bushing on its far side with the MS21042-4 locknut supplied.
Use a 100 degree piloted countersink to prepare the outer fishplate for the newer Yak 52 style Axle that has a slotted countersunk head.
Installing these bushings with a Yak 52 style axle eliminates the lower double locknuts which are difficult to adjust - creates a robust bearing surface between the aluminum ring and the new steel bushing and provides easy axle tension adjustment using a flat blade screwdriver.

Baffle, Oil Radiator Inlet, Yak 50
Unlike the Yak 18T, 52 or 55, no provision was made on the factory Yak 50’s fiberglass Oil Cooler scoop for fitting a cold weather blocking panels.
These days, many Yak 50’s are to be found outside of Mother Russia, fulfilling a different mission in their new homes. Owners may find this device a useful modification that will keep your oil temperature in the green arc during the few months of the year that require it.
Just like TYC’s baffle for the 52, those four vertical tabs may be bent back to further block the exposed area of the Oil Cooler. The intent is to adjust them to find the sweet spot for your local winter operating conditions - then leave them at that angle. They are not intended nor will they survive more than 3 bending cycles.
This kit includes:
- 2 securing wire clips,
- a fixed hinge section that gets riveted to the lower mouth of the radiator scoop plus
- 2 upper clips that you rivet to the upper roof of the radiator scoop opening.
- 9 pop rivets are provided for installation.
- the baffle itself, with rubber mounts that go against the Oil Cooler face,
The baffle is anodized blue to distinguish it from the equivalent Yak 52 part. The two clips and fixed hinge are supplied clear anodized so you can paint them to match your oil scoop.
1.Begin by placing the hinged assembly (as delivered) in situ.
2.With the rubber buffers firmly against the radiator fins, use a drill & Clecos to position the lower hinge ensuring the door appears centrally placed.
3.Next line up the small clips with the two prongs along the upper edge of the Oil baffle. The small joggles in the clip face downward & overlap the prong, preventing them from moving forward.
4.The two rivet holes in these upper clips are close together and use of Clecos may not be possible. Secure both these fixed upper clips with four of the nine pop rivets provided.
5.The pins of the wire clips are designed to be passed through the formed hinge holes from the center, outwards so the wire overlapping takes place at the outer edge of the baffle plate.
6.To release the baffle plate, after removing the wire clips, rotate the lower edge of the baffle forward toward you 45 degrees or so.
7.Move the baffle downward slightly so the upper prongs clear the upper clips, then remove it.
8.To install the baffle, first remove the wire clips then rotate the upper edge away from you as you engage the upper prongs behind the joggles of the upper fixed clip.
9.Swing the lower edge down until the hinge holes line up and secure the plate with the wire clips.
Make inspection of these wire clips part of your daily pre-flight, so that as the weather becomes warmer you do not overlook whether the baffle is still necessary for flight.

Valve adjusting tool set, M14-P/Houssai - Repro
This pair of reproduction Factory valve adjustment tools is made from heat-treated chromoly steel, plated for long life.
These tools suit either Vedeneyev or Houssai engines.
Two Additional functions were designed in - the first completely unrelated to valves.
The square hole in the socket handle is for installing/removing the 7mm plug in the right hand side of Nose case (where cast-in passages supply oil to the Prop Governor.)
Second, the slotted cylindrical boss on the other end the blade tool will help you over-center the wire ring that secures the valve cover.
Ideal wire tension is such that you can almost over-center the D closure with your finger or thumb. (So adjusting the threaded D to where you can barely do it with all the newfound leverage of this tool is not the goal. )
Instead, use the added ‘feel’ from this tool to evaluate and adjust the wire loop tension to the ideal value. Any tighter will shorten O ring life unnecessarily.
Used in the valve adjustment process, the 12 point socket releases the valve adjust nut, and allows you to hold it where the nut is just starting to ‘bite’. Then insert the blade and adjust the slotted center to the required valve clearance (using a shim between rocker and valve.)
Holding the blade tool still at the desired clearance, use the socket in your other hand to snug the nut.
With a little practice it’s a great procedure for getting your valve clearances right the first time!
