Dave,

I didn't have any trouble with mine so I'm thinking maybe you have the lever going under the lobe rather than riding on top? In that case I would make sure the lobe is pointed down before installing.

I don't know.

Dave,

I turned cam so the long part of the lobe is facing in towards the center of the engine and I am pretty sure that the arm was on top of the cam. I'll give it another shot as soon as I get the bolt out and order a new bolt.

Brake Lines

Post by ocwd »

I am running my brake lines. Any one have any pictures in their photo album that would be useful? Just wondering how the lines coming off the master cylinder are routed. It'll probably work itself out but some pictures would be nice.

Still trying to dig the busted off bolt out. It's mostly drilled out but having trouble picking the remnants out of the threads. :roll:

This is all I have. I have an a1 but I think they are the same?

The line running from the back goes into the boxed part of the frame and out a hole.

Brake Lines

Post by ocwd »

Well, I got the fuel pump bolt out.

The brake lines are mostly run. And, If I had to do it all over again, I would install the brake system before installing the engine and steering box.

Thanks for the picture Dave. It looks like the front brake line is a bit different between M38 and M38A1.

Progress

Post by ocwd »

Thanks Wes. That helped. Brake lines are in and I am waiting for a replacement fuel pump bolt. My carb is off being rebuild. I will probably test run my engine using the Solex until my correct carb comes back. I couldn't find the correct hose size for the hose between the cross over tube and oil filler tube. I just used what I could find. It works OK but looks a bit stretched out.

Looks great Dave.

If you are using a new brake line kit, don't be surprised if you get a leak hear or there. I found that I had to tighten up the lines more than I thought. Must be the initial seating of the flare. After the initial seating they seam to seal without much effort.

Yes, much easier to run the lines with the engine out but could be worse. At lease you have your tub and fenders off.

Fuel Pump

Post by ocwd »

I swear something is not right with my fuel pump or engine plate. The bottom bowl does not match up with the rectangular pocket in the front engine plate. Does anyone notice anything unusual in these pictures? t also looks like the top bowl is riding on the top of the engine plate.

Your pump looks correct. The spacer looks like it is about 1/2" so that only leaves the front mount plate as suspect. Since the civvy dual fuel/vac pump has a smaller diameter upper pump section and does not use the spacer I would assume that front plate is from a CJ3A or CJ3B. What model pump was installed on the engine originally?

I think you need to extend the lower pump bowl opening in the front plate aft and trim a little that contacts the top pump section or get a M38 front engine plate.

Engine Plate

Post by ocwd »

I'll Have to think about it for a while. I am guessing that I will get the correct engine plate. I'll post here and on G503 to see if anyone has one. Here is a picture of my engine before it was rebuilt. The previous owner told me that he removed it from a generator housing and the rest was scrapped. I purchased this front engine plate on Ebay for $20.

I thought about changing the plate also but I wasn’t up to taking the front of the newly rebuilt engine apart and trying to pull the gear off the camshaft can be a pain. Good luck with your project..Jeff

Front Engine Plate

Post by ocwd »

Got back to work on my Jeep last week. I removed the timing gear cover and pulled the fiber timing gear. My engine was timed with the fiber gear and crank shaft gear marks lined up and the timing mark on the flywheel lined up also. Then, after I pulled the fiber gear, and like a big dummy, I turned my engine. It seams that it should be pretty easy to get everything lined up again.

I'll need to replace the timing cover and oil pan gaskets now. Anyone have an opinion on the oil pan gasket? I have one cork gasket and one paper gasket. I used a paper gasket and RTV last time and it looked like I had a pretty good seal.
