Glad it was helpful! Not sure if I said in the video, but I will be putting this in a Speedy Bee I will be building soon. I think these types of engines are great for either the lazy or speedy bee. Thanks for the comment

Lucky man would love 1

Thanks

Hi, thanks for the comment. The dot is lining up with the bottom of the push rods, hope that helps 😃

Thanks for the comment, pleased you found the video useful. Those collets on the valves are horrible to do, having a plastic back to catch them is a great idea. I usually just hold down the spring with my thumb nail while I slip the clip in, holding the clip with forceps, but yes not a pleasant job and always a relief when done!

Hi Steve, much better to take the bearings out and measure them before ordering, than to trust someone else's word, then you will know you are ordering the right sizes. I can't help you with US suppliers, I ordered mine from Henderson bearings here in the UK. Both bearings will be a fairly common standard size.

Sorry, I dont have the part number, the best thing to do with any engine is remove the old bearings and measure them as there are some times variations in the bearings used. This way will ensure you get the right size first time round. The bearings for this will be a fairly standard easily available size.

@@MarkRobinson555 Hello Mark. The original bearings where NSK 6901 and 698Z. I have ordered the SKF 61901/6901 and the 619/8-2Z. The front bearing is double side shielded and the original one single side shielded. Could only find the 2Z version. Hopefully ok.

Hi Mark, thanks for the comment. If my engines are really mucky I clean them in an ultrasonic cleaner, using a product called SeaClean2, which is available in the UK, but not sure about elsewhere in the world. As I am sure you know you do have to be carfull as some cleaners will darken the alloy, think some of the carb cleaners are probably very good, but always good to test first. Also use a toothbrush and soap! To clean between the head fins I use a credit card and some very fine wet&dry! This engine, was not too bad, despite being mucky inside, think it was fairly low runtime, just not looked after, so all I used was a tooth brush.

I just got an FS 26 that needed considerable work but it was an unbelievable bargain. I use an ultrasonic cleaner and a product called "L.A.'s Totally Awesome" dilute 1 part Awesome to 4 parts water. It does a remarkable job. Without an ultrasonic cleaner I have used Awesome undiluted and diluted 1:1 and light scrubbing with a nylon parts brush or toothbrush. In the US it's available at most of the "Dollar stores," Walmart, Home Depot and Amazon. It's very inexpensive.

I would remove the nylon pade each end of the pin, soak for while with thin oil, then heat the piston and place on a block of wood with a hole in it just larger than the pin and gently tap with a bronze punch, and it should slide out. But, only tap lightly, too hard and you could damage somthing.

Thanks but you are assuming I already removed the piston. I cant get the piston out, how did you do,that?

You did ask how to remove the wrist pin from the piston, did you not? If you need to remove the piston and con rod from the engine you need to remove the head and back plate, take the cylinder liner out and then the piston big end will slip off the crank and the piston and con rod will come out the top of the crankcase. Is that what you are trying to do? Hope that helps

So I got the small,plastic pad off, but not the pin. I applied heat, and turned the piston to TDC, then used a small pic the pull the con rod off the crank. It worked. Turns out you don’t need to remove the wrist pin. So now I was finally able to remove the bearings and have new ones on order. Cleaned up everything in my ultrasonic cleaner, looks like it will be a new engine now!

Hey, have you not done that little job yet?
