McCulloch Titan 50 57 lines

[chainsawwhisperer]

I have to agree that the lines on the 50/57 are a pain, but once you do a couple you figure out that ...they are still a pain. lol
The crank case oil seal/ oil pump ass. is strange.
Any of you guys have a chain brake/cover for a Double Eagle 50? or Titan 50/57 ?
Thanks Jim

Here what one of mine looked like a few months ago, I had to make a case gasket for it.

With the exception of the case split that is how I received mine. I wasn't going to split the case I figured I could clean the outside with simple green and water with a rag around the piston and rod and then remove the rag and rinse the inside out and flush the clutch side bearing with premix to clean out the crank area?

Here are a few photo's showing the Titan 57 in a bit more detail. First up are the typical condition you will find when you take one apart. Pretty good chance there will be several bit that just fall out, maybe an elbow and a breather/vent since the lines have turned to crumbs.

Here is the tank off before clean up, the lower two holes are in the fuel tank for the pick up and vent. The upper hole is where the Tee fitting plugs in for the oil pick up.

And this one is for the oil tank vent.

Here is what is left of the oil pick up line. The Tee simply plugs in to the line and makes a friction fit in the hole.

To simplify installing the fuel line, I ran it all the way through the tank and installed a more conventional fuel filter, then pulled the line back into the tank.

There are two vents, one for the oil tank and one for the fuel tank. The oil tank vent is the horizontal line on top, fuel tank vent is plugged into the fuel tank below and pointing up.

Here is the manual oil pump, the longer fitting on the bottom is the pick up /inlet, the top with the clamp is the outlet.

I opened up the clamp with a small screw driver.

Here you see the manual pump installed with the outlet clamped to the top, the inlet can just press over the barb on the bottom.

The oil pick up is pressed into the tank, and the tank portion is plumbed and ready to go. Notice the fuel tank vent is now installed as well.

Oil pump and oil line removed.

New oil pick up line installed and the pump back in the saw. There is a spring inside the pick up line to prevent it from kinking or collapsing. I would recommend priming the pump before you put it all together as it takes a long time to prime the pump once you start the saw.

The hard (black) plastic line supplies oil from the manual pump to the saw, the pick up line for the oil pump is the tygon.

Here is the port for the impulse line...

and here is the fitting that installs in that port.

Impulse fitting installed...

and the impulse line connected

Before assembling the tank to the engine, be sure to put the retainer plate for the bottom of the handle in place...

I installed a couple of screws to keep in it place.

Here is the large "hose pliers" I used to squeeze the clamp joining the flexible oil line over the hard plastic delivery line to the saw.

In hind sight, I think it would be easier to connect the lines to the tank portion, then pull them back through the opening in the engine when you put it all back together.

One thing I did not show is one elbow fitting between the flexible line on tee (pick up) that connects to the long flexible line to the oil pump on the engine, this makes turning the corner possible without kinking the line.

Wow Mark! those photos and instructions will be great for me later this week. I just got my dead diesel jetta back up and running and can get back to the titan. Thanks for the pics and time spent to Detail the process for us.

Spent a half hour or so cleaning this crank case up. Rinsed good with mix, bearings feel like crap. Maybe this is why it was in a box in a million pieces. Guess i will pop it open now...

The case splitter I built for my Pioneer 25 fit perfectly on the Titan 50. Popped it open, sprayed out bearings with carb cleaner, let it air dry for awile and sprayed WD40 in all the bearings. Feels smooth now, no rough patches. Do you think I can reuse the old case gasket if I use laquer thinner to clean it up and then use high-tack on both sides?

 

[heimannm]

Keep in mind that you must have a perfect seal, if the gasket cleans up smooth with no tears, scratches, our gouges out of it you should be O.K.

It came off very easy. Wiped both sides down with paint thinner then laquer thinner. Do you think high tack or motoseal would be better?

BUMP oke:

 

[briantutt]

Ahhhh. Looking better now. I need a fuel filter and a new oring for the pulse fitting so i can't mate the halves today...

This pic is better i hope

Can one of you guys confirm the correct spark plug is DJ8J for the titan 50?

According to Chain Saw Collectors Corner it is one of these; AC CS45T, Champion DJ8

Great photos! Your rebuild looks to be coming along very well

Best of the season!

It seems the titans are "the" winter" project saws. I just picked up a titan 50 on CL and Mitch sent me a tank for my 57 that was crushed when a loaned it out to a friend. The saws are easy work on but just take time to do all the lines. I find the titan 57 to be a much nicer saw than a 3.7 timberbear. Hopefully the 50 will be just as nice.

Looking good guys! I was pleased with the power my 57 produced.

My lease was up at the end of the year so I cleaned out my old shop and moved everything over to the new one. I found another near complete 57 and a complete 50 in the pile. Seems that I have given away all the good coils I have left though lol.

Rob, I have that carb "bucket" but no filter.

Jim, I have the chainbrake handle you are in need of. PM me your addy and I will get it out. It is already boxed ready to go.
