Thank you for this ! Just had a fight against gravity with my golden knight FA100 which damaged rear bearing on impact . So everything needed to come apart and be replaced . But this is the first you tube I found on timing it .
Hi David. I just tore down my FA-72. The timing mark on the cam gear was mated to the shaft at BDC not TDC. Does it really matter since it's a glow engine (not driving a spark)? Thanks!!
Another cool trick I learned with Saito cam timing is to put one side of a strong rubber band under the rod pin and the rest around the case. This holds the crank at TDC. Thanks David !
Pulling the timing gear from Housing , I thought would be evil to get the nylon washers back in place , some oil to hold them and went back togeather fine . Question , after cleaning ,i was putting barrel back in carb, a turn felt a snag so removed the barrel and had a look inside the carb body and it appears someone [before me ] had taken flat screw driver and scoured around inside the body [ for what reason?]. Since inside the body is etched with ? some tool , WILL this allow more air to enter ?causing lean and had I better find a new carb housing? The barrel rotates in the body OK , after i used small emory paper and went around inside with some oil. Thanks
I have a FA-65. It's all apart. When I try to push a screwdriver (or a T pin) down the intake valve, I hit a wall. And it's not the cam shaft. The camshaft turns freely. I can't get access to it. I've been soaking the cam housing in Marvel Mystery Oil and heating it to see if something will break loose. Short of taking a punch and a hammer to it, I don't know what I'm trying to break through or if I''m supposed to get aggressive with it. Thanks for any advice.
Sounds like you are headed for destroying the engine to me. It is a simple as I have shown. If it isn't then there is something wrong and you need to find out what it is. Have you taken the timing gear off the engine and the gear out of the case? Not much information provided but the path you are going down is the wrong one.
You never answered the question, let me rephrase what the guy said - how do you put screwdriver through the hole there's a tappet inside - how to remove that first. I am completely stuck with my own 56 engine trying to find this answer
David McIntire hi just want to ask i follow you video and started my saito fa 91 i notice that it consume too much fuel and going out of the muffler, try to put my hand to feel the smoke coming out but its too cold thinking throwing fuel without burning it and cosume the nitro immidately? Can you share possible problem?
as you said david the darn cam gear is very free/ i wedged a bit of dowel rod into the guide to try and generate a bit of drag i wonder how criti acil are they if they are out a tooth?
David, Does one Need to remove timing gear from the case . in order to push out the ? tappet from the case , In order to insert a driver; down in the hole of timing gear? could not find a video on timeing gear case . Thanks
If the timing gear isn't removed then the timing can't be off. Yes the timing gear must come off you you intend to replace bearings. The crankshaft cannot come out without the timing case off. I show this is several Saito videos, just watch them all!!
I see what ya mean , as I see the timing gear OUT of the case in container with all the parts . I've had all the parts in the Ultra sonic , cleaner is brown now . I just hate trying to get the nylon washers back on the shaft in the case . Patience Patience Thanks
Let me amend what I said above. If the timing gear has not come OFF the crankcase, then the timing is not messed up. If you have removed it from the crankcase, then yes it will have to be re-timed.
I found a screw driver phillips that the OD was almost the ID , but not quite snug in tube to lock gear in place , looked around found a small plastic straw that would fit where push rods go . So with straw and phillips , it was SNUG and held gear in place. I found that getting shaft at TDC , was easy - with bolts that hold cyl on ,screwed into block, was able to keep wrap around where connecting rod attaches , looping rubber band around and up and around the 4 bolts . Held it up just perfect at TDC. then lower the timing gear etc down on shaft.At first it would not mesh ? Further exam showed the main bearing was not fully seated! urrg Back to heat and press- fully seated timing gear meshed just fine. The Ultra sonic cleaner worked well , the Yellow cleaner Awesome Al's , was brown after several timed runs .
Hello David, i have a problem with Saito Fa 56... I have watched your video, but i can't figure it out how to lock camshaft for timing. When dot on gear is at bottom, i put screwdriver in intake hole, but it don't want to lock in place! I don't know what i am doing wrong.
Older 180? The FA-180 is one of the later model engines. I am about to reassemble a 180 this weekend. To see how I did it on my 120S watch this. th-cam.com/video/crgxE_5x9Ig/w-d-xo.html
For my 120S I could not use this method. Watch these to see why. th-cam.com/video/wq8vJ763sBI/w-d-xo.html See time mark 2:14 And this, th-cam.com/video/crgxE_5x9Ig/w-d-xo.html
OK, that explains why I couldn't use the Hole/Screw Drive method. I'm waiting for new gaskets and need to clean up some carbon build up but the engine is in pretty good shape otherwise . Reason I'm doing the was a clanking noise heard when spinning the Starter and lack of restart. I did get white smoke out the exhaust strangely enough. Your Videos a greatly appreciated...well done Dave.
Hi Dave, just updating the clean up of both my Saito 120 and Saito 52 four strokes that you helped me with. Both are running perfectly. One note to mention that you might like to try when setting the timing that I did was to determine exact top dead center an easier way. On the 52 Saito I had the head off and just watched the cylinder come up to the top of the cylinder, and on the 120 with the head is still on put an allen wrench down the hole to touch the cylinder head and just watched it , rise to the top. Worked perfectly and was easier then watching the connecting rod through the back of the case when putting the Timing gear in.
Sorry, but you have it wrong for the first series Saito 150 the cam followers are shouldered, so you can't pull them out to put your screwdriver down the hole, they come out only after you have taken the cam gear out.
Thank you. This video was made before I had ever worked on a 120 and up. if you look at my later videos you will see the correct information for those size engines.

Thanks for the video! I plan to replace the bearings in my 15 yr old Saito 100 this week. Engine runs great except for noise original bearings.
Thanks for your very helpful videos David,much appreciated,cheers from Australia.
One question David how do you remove the cam followers so you can get your little screwdriver into the hole in the crank?
@@sarahhoskins8492 I also would like to know this
Thank you David!
Learned alot throu your channel.
I returned to rc airplanes a few years ago and went with 4strokes saitos.

Great videos, when you insert the push rods back in which end of the push rod goes towards the bottom ( cam housing) the tapered end or the round end?
The round end goes into the cam, the tapered and goes up into the rocker arm.
@@dmrcflyr2 thank you David
thank you for the video... but how much torque do you put on yhe head bolt... 25 pounds?

as you said david the darn cam gear is very free/ i wedged a bit of dowel rod into the guide to try and generate a bit of drag i wonder how criti
acil are they if they are out a tooth?
Extremely critical for proper operation. Depending which direction the tooth is off will make a big difference in how the engine runs.
thanks david/ you are running a brilliant forum heare!!!
Much appreciated.

Well I really don't know what to tell you.
David McIntire Ok, i will figure it out... Can you please tell me marks, numbers for bearings for Saito fa 56... Thank you very much!
The front bearing is a MR698 and the rear bearing is a MR6901. The numerals are the most important part.
David McIntire Thanks David, cheers!
whats the story, with the older 180 fs the cam followers have to be in the housing before assembley??

Thank you my saito 62 are poor running not peak RPM then I try with your tell.
Thank you sir!
Perfect Timing ( pardon the pun) I just opened up my SAITO 120 to clean it up and was wondering how to set the Timing.
For my 120S I could not use this method. Watch these to see why.

Tip: A strong rear earth magnet on the outside of the timing gear case will help hold the gear in position.

Just what we wanted to see 😀🇳🇱
Very great lesson! thanks man
Thanks for sharing
I can't get the video to load. I can load other TH-cam videos.
I think it is a TH-cam issue. I can't see any of them now either.
thank you!!
En saito fg61 bicilindrico no coincide.
¿Dije que era para motores bicilíndricos? Este video es para un gemelo boxer Saito.

@@dmrcflyr2 perdón, no te enojes, muchas gracias
Engine continues to misfire since rebuild. Yes the timing is correct.
What engine are you referring to? If it misfires either the timing is incorrect or the tuning is WAY off.
Thanks for replying. It was a rookie mistake on my part. I installed the incorrect drive washer. The magnetic pickup was off by 90*.
