OEM-like rivets? Oh boy....

Very cool. If you wanted to save some money on the gun, bucking bar and oven I'd bet you could bring stuff up to Ogden and get the D&RGW 223 group to buck them for you. They've bucked roughly 5000 rivets rebuilding that locomotive's tender over the past two or three years...

Hello all - getting back to work on the BJ42 and have her quite taken apart.

I am going to be replacing the clutch. Do you guys know if this is the correct clutch?

NAPA AUTO PARTS

NAPA Part# ATM0762407

I went to napa.ca to get the number and then napa.com to find my local price. 360 dollars, ouch.

Also, what's the going rate to turn a flywheel these days? It's been a good 2-3 years and I think I paid 50-60 bucks?
 
Good to see you workin' on it again! I got my clutch at 4Wheel but then I am only 300Km away and in the same country as Dan. My flywheel I will take to a local shop called Pat's Driveline. They do all sorts of diff and tranny work right up to industrial stuff. Should be a shop around you that can do it. Just ask a local gearhead. I was told by a former employee of Pat's that it should run about $30-$40 in Canuck denero so should be like $5 down there :bang::lol:
 
Sweet! And that looks like Genuine Toyota stuff at about the same price as local. I'll check them out.

To be honest, I just threw the old clutch in there to mount/adjust the 3B....and it is haunting me. So, I plan on taking it all apart now and just doing it right.

Question: Since this 3B is out of a BJ60 - is the slave cylinder/clutch throw the same? I tried to adjust it and I am not sure the "throw" of the slave nor the length of the push-pin into the slave is the same as a 40?

Maybe I am wrong and just need to spend more time adjusting. . .not sure.

thanks!
 
I used the the 42 bell housing on mine and it was different from the 60 since I had to get a different slave then the one I got with the tranny.

You should be good brother.

I used the stock '79 FJ-40 clutch master/pedal assembly to drive the BJ-60/70 clutch slave cylinder. Works a treat!

The bolt pattern was different on both BUT basic size and shape were the same

Yeah, there's a few bolt patterns out there (even different depending on the year of BJ-70), but in terms of fluid movement and clutch engagement.... you'r good to go.

BTW Dallas--we've still got the "wrong" clutch slave new in the box if you want to measure the bolt spacing on yours we'd let it go for a song. Just cluttering up the shelf right now...

Here is what the slave cylinder looks like:

Looks to be about an inch and a quarter-ish center to center of the two 12mm's?

I hope it works out ok and I don't have to hunt for a rare bellhousing and slave cylinder!!
 
That looks like mine and I was told its for a 40

This is the BJ60 one that didn't fit mine

Yours looks exactly like mine, which is a BJ42. Looks like your going to have to weld your clutch fork or do what I did to prevent the push rod from extending too far out due to the puncture in the clutch fork. Based on another mud members fix I used an acorn nut on the end of the push rod where it cradled in the clutch fork hole. If you don't do this you'll end up unevenly wearing the slave cylinder, which will result in an early fail. I had to replace mine after only a few drives around the block.
 
hmmm - I am not sure I understand what you mean. Did you happen to take a picture of what you did?

I was told this 3B/Tranny/T-case setup came out of an 81 BJ60. Did the early BJ60's and 40's have the same bellhousing/slave?

Are you saying that when I push the clutch, as it is....the slave will extend too far? Thus - tack welding an acorn nut onto the end of the slave push-rod to get the same results without extending too far?

Sorry for being dense on this....just trying to understand.
