Finally got around to fixing the hydraulic line that got a pin hole in it. Had a new one made at a local hydraulic shop. Also got the brakes working some. In all the line switching one of the lines got left loose and all the fluid was escaping. I got them bleed some but I think it needs to be...

I am but if I trade it I would like to trade toward a 5 ton so I can get my 816 running.

Well it looks like I'm going to have to go into the tcase. I finished putting all the torque rods and rear drive shaft back in so I decided to take it for a drive around my yard. While driving forward I kept getting a loud bang and the truck would jolt. I pulled the front drive shaft and I could...

I'm missing one leg from my 5 Ton myself.

So good new bad news. The threads on the 2.5 ton are just shy of 1 3/4 and the threads of the 5 ton are just shy of 2 1/4 so there is no using the threaded part from one to the other. The good news is the overall outside of the pipe is about the same on both trucks. So you could put a complete 5...

If you need to remove an axle for an M108 the out rigger are real handy. The rear drive shaft was missing when I got the truck and I was already changing the torque rods so I figured why not just roll the axle out to make beating the torque rods out easy. Made knocking the frame ends out a snap...

A Cat with an Alison behind it would be fun. The guy that sold me the M816 was trying to sell me a v12 Detroit engine and a HET transmission to put in it. That would be a monster.

I'll give that a check. I just hooked everything up the way it was when I got it and figured it must be right. Also I was corrected, what I have is an M816 not the M936.

Well it looks like I'm going to have to let my M108 go to fund a new project I just purchased. That being an M936 5 ton wrecker. The M936 is missing its engine and trans plus a few other things but I couldn't pass up the deal I got on it.

The joys of working with a 66 year old hydraulic system. I replaced the steel line and the rubber line for boom up and everything works.....But and there is always a but. The cylinder for boom up has started leaking from the head nut. Has anyone removed the main cylinder on a 108? Trying to...

You can really tell the boom is bent when the extension is out. I removed all the outriggers to free them up and found something fun. It looks like they bent two of the outriggers so they cut the 1/2 inch wall pipe off and replaced it with some 1/4 wall pipe. Because that will work right? :roll:

SUCCESS. I hooked up my new line and checked the function on all controls. It had to whine a little while fluid was being sent to places it hasn't been in years but all functions are working. Well they where until one of the steel lines for the boom raise popped a pin hole in it. I'm going to...

Here what the fitting looks like. I got it from Hydraulic supply company. The part number from them is 2024-16-16s. They said they have four stores in Georgia so there might be one near you.

The fittings in the control box are standard fittings you should be able to get at any hydraulic supply shop. The control block uses NPT threads I think it's consider 1 inch NPT. So you just need NPT 90 degree to JIC fittings. I'm going to get some tomorrow and I'll get you a part number.

That's an idea. I will defiantly fish plate it after I get it straitened if I go that route. For now I still need to get the hydraulics working to see if the inner boom is bent too.

So it turns out cattelrepairman is correct there is a bend in the boom. So I'll be on the look out for a new boom for it. I'm going to keep working on it as I don't think I'll ever pick up anything that would stress it further but a non bent boom would be nice.

Here is the control box. You can see two fittings have been changed by the last owner to modern JIC fittings. Most of my steel lines have adapters on the end to use JIC as well.

cattlerepairman I'm not sure but it is possible there is a slight bow in it. SETOYTA Mine has adapters to go from the old style to JIC but a few are rusted out so I'm going to change the fittings at the control box to make them all JIC. Getting JIC fittings that size is no problem if the price...

Made a mile stone yesterday. First time running since the tear down. Still need to get some hydraulic lines made before I can try out the crane. I had one made last week and wow. 150 buck for one line and there are ten total. Here's the truck now. Also got an idea on what year it is now to. I...

Ya it's real tight between the nut and yoke so a normal socket won't fit. It's an 1 1/2 socket. I used a punch to get the nut loose but figured I had better put a a bit of torque to it so it didn't back off.
