Original dimensions,new original 2F camshaft...

[Landcruiserfj45]

Hello folks,

I have a question about the original 2F camshaft.
The dimensions in the repair manual are,so to speak,the wear dimensions.
I mean the dimensions I circled in the foto.
Does anyone of you have exactly these dimensions of a brand new original 2f camshaft ?
Because if I were to have my camshaft overhauled,the engine builder would have to have the original dimensions when it was new,so that he knows how much he has to weld on before he grinds the cams again.
Because if he just grinded the cams like that without welding them on,the cams would become shorter and therefore the valves wouldn't open wide enough,or am I looking at that wrong ?

Thank you very much for your answers and have a nice day,

Jürgen

A real workshop/facility would have that info IMHO.
You need a camshaft for a Merlin - yep you will find repairing yours a good plan.
Welding up and grinding is an option - I'd want a place that does it for a living. I worry about finish, heat treat, straightness and the dizzy gear

The OP is in Germany, as in Europe..

From the 1975 2F OEM factory service manual:

 

[charliemeyer007]

Yea I saw that. Its on planet earth. Shipping isn't that big a deal anymore. A whole engine is a different story.

When they grind it, they should take it off of the entire lobe. So the whole lobe or teardrop becomes slightly smaller but keeps the same distance from the base circle to lobe tip (centerline of cam to lobe tip vs centerline of came to lobe heel). The slight difference in height should be able to be taken up by the rocker arm adjustment. If that makes sense.

Yes great,thank you very much for the measurements !!!
Unfortunately,the dimensions are not in my 2f engine book from 1980,only the wear dimensions...

Here is a photo of one of my camshafts.
Doesn't look really good anymore I think...

Hello Jürgen,

I understand your concern based upon the pictures of your camshaft.

This is a link to a later 2F engine factory service manual available here in the resources tab.

FSM - 2F Engine Repair FSM 1991 printing

De-bound and good scan of manual. -Argyfoe

forum.ih8mud.com

That manual is what you already have.

Try this link, Land Cruiser manuals, FSMs, and repair resources - https://heritagecruisers.com/pages/manuals
and you can see the camshaft specification table in the "1991 2F Engine Repair Manual (98126E)"
It lists the camshaft data on page 10-9.

Soooo, I haven't written anything here for a long time, but now there's news, although not particularly good news.
I ordered or bought a brand new original camshaft for my 2F, the seller got it somewhere from Dubai or something.
A few days ago the camshaft arrived and I was very happy, unfortunately my joy only lasted until I unpacked the camshaft. I almost went crazy when I held the brand new camshaft in my hands.
Luckily, the seller understood that I definitely didn't want to keep the camshaft and immediately offered to take it back and transfer my money back, which he has already done.
I'll show a few photos here so you'll definitely see immediately why I didn't want to keep this brand new camshaft.

A kind greeting from Germany,

Jürgen

Wow that's a lot of rust. How did they not notice that, would be fine for a candidate to re-grind but being sold as new. It is nice they gave you your money back too bad they wasted your time. Mail order is sadly often not without issues. I would try again as the motor is a brick without a cam shaft.

Sometimes dried grease looks like rust. I have bought ebay old bullet molds that looked like that but cleaned off with brake clean.

The dealer from Germany who got the camshaft from Dubai did not unpack and check the camshaft after it arrived, but sent it directly to me.
But luckily he takes her back.
And unfortunately it wasn't dried fat, but definitely rust, unfortunately.

I thought back and forth for a while about what I was going to do now and came to the following decision.
I'm going to send my old camshaft to Tacoma to DELTA CAM and have it reground into a KC859.
I wrote an email to Delta Cam and got a reply.
And I think it's a really great price that they quoted me...

 

[charliemeyer007]

I thinks that's a good price. I see shafts listed $300 up to $750 rv regrind with springs/lifters plus a $150 core charge and shipping. I hope it works out for you this time.

Hello good morning from Germany,

Before I send my camshaft to Delta Cam in Tacoma, I have another question for the professionals here.
If the camshaft is now ground, material will be removed and the diameter of the individual cams will become smaller.
And if the cams now become smaller, then the valves no longer open far enough, which would actually be counterproductive, or am I making a mistake?

And since one or the other probably uses the Delta Cam KC 859 camshaft in their 2F, how does this change the engine characteristics?
I don't want to lose torque under any circumstances.

Thank you very much for your answers,

Jürgen

I think that they grind the metal from the entire lobe surface, that way the difference between the high and low remains the same for small correction. Others with more damage/wear they weld them up and then grind them back to spec.
