I have seen that site before and it is very interesting but I feel that the tool he used to remove the heads is more complicated than necessary.

I feel the single plate design is perfectly adequate for safely removing the heads. I don't really see a need for the extra plate and hardware needed for the 2-plate design.

As soon as I get the dimensions needed for the single plate design I will have it made and tested.

Good Luck with the puller Mark. If you want a shortcut to obtaining all the required dimensions you might want to try here?

The tool may be a bit of an animal but it hasn't been known to fail yet. It makes the job easy, is satisfying to use and can sort out the Greek debt crisis (OK - I made the last bit up).

All proceeds are added to my project money-pit (or maybe just a few beers to help oil the wheels)

I with you on that! I've got three of these beasties to care for and possibly another on the way.

Too help offset the cost I've been thinking about bolting all of the cars up to a wheel and taking it to the local carnival. I'll charge a buck per ride in a genuine "Jag-wire".

Please look at mine! You will have to remove come shaft any way! this is ridiculous! believe me it will work!

 

Hi Marek
More often than not a more flimsy tool will work. However, I have come across engines where the damn heads are pretty much stuck. This beast will pull heads even if the odd nut is left in - not recommended though :-)

 

I want to get one like that also but this is Jaguar it will come of like bandage from the scar.Just gentle moves on the screvs! Believe me!

 

I have had my step son build one of these "tools" using the pdf and a CNC machine at his work and the dimensions are all spot on, it slips over the cam bolts fine and every bolt hole lines up with the studs poking through the head.

The interesting thing is that even after using lots of penatrating fluid and hours soaking the head will not come off. I have so far bent two sets (14 bolts each time) of 8.8 grade bolts trying to pull the head up. The bolts bend so much i have to cut them off as they cannot be undone without damaging the thread in the "tool".

Any advice would be welcome


Well how embarrassing I was in to much of a hurry to try the new "tool" and I didn't have all the nuts undone! what a idiot i must remember the additional nuts on the timing cover

 

not sure where you are to rent this head puller but I am in Brantford Ontario Canada

 

Why would you "rent" one for $150? Simply download the plans and have your local machinist make one off your plans for the $$ instead of renting it.

 

Excuse my ignorance, do you have a link to plans for a proper heavy duty V12 head puller ?

 

I'm in work on it. I've a friend in the club with one. I may be able to barrow it and take some pictures, measurements etc.

 

If you fill out the info on the link the gentleman will email you complete plans (he sent the to me an hour after I submitted) put v-12 head remover in the subject and ask for the plans in the message.

Anyone needing this info can PM me their email address and I'll forward it to you.

 

If you are having the head machined, have it done by someone who knows these engines.. The heads can warp, and if the shop only machines the side that goes against the block,, when you install it, the other side gets twisted and the cam can't rotate.. Have them machine both the top and bottom of the head.

Don't forget that if the head is machined, you will have to adjust the valves.

 

Thanks, contacted Neville at xj13 and he very kindly and speedily emailed detailed drawing for making 'the tool'

 

JTsmks,
Do you have any pictures of the Neville head-pulling tool in use? I am having one built but I cannot seem to find any images of how it is used. Thanks.

 

jcna rent them I believe

 

There is a recent post on this....

I have the drawing if needed but all info is here.
PM me if needed.

 

RGP JCNA does not rent tools but rather loan them to members. https://www.jcna.com/tool-loan Recently we were allowed by our carrier to stock the one and only tool that is not factory-----a V 12 head puller!

I appreciate everyone's effort to help. Maybe there is some confusion in what I call the "Neville" tool and what other people are thinking of. I purchased the plans from Neville Swales for a very unique looking two-plate tool. The pictures to which I was referred are all for the single-plate type puller. I am currently borrowing a single-plate type but, I am paying a machine shop to produce the two-plate tool.

My question is does anyone have any photos of the two-plate (I call it "Neville" tool) in use. Sorry if I confused anyone. Thanks.
