JD115 front spring compressor
 

I have recently acquired the drawings for the elusive JD115, I was just going to have one made for my own use but it became apparent that if I could find a few more people interested in having one the price would tumble. I have contact with an engineering firm that can make a short run of 10 - 20 for between 150 and 250 depending on number of items.
As I'm not in this to make a profit but just get to get the price of my own one as low as possible, I can pass these on at cost plus shipping to anyone interested. so if any one is interested in the chance to own this rare and useful piece of equipment please PM me.

Front Spring Compressor
 

My Google search turned up your post indicating you had plans for the Jag front spring compressor, and your survey to see if anyone wanted to participate in an order.
The cost and shipping to me here in Canada would likely be prohibitive however I am also in need of a compressor and am planning to build one.
Any chance you might share the plans (or sell a copy for a modest fee)?
I would use grade 8 fine threaded rod and just neet the bottom collet pieces from a machine shop (re; the need for the plans)

I could design the collet pieces myself but if I could get the actual design from you it would be safer.

Thanks for your consideration of this
Dave

Dave,

This thread is two years old and I'd expect grommet's compressor issue has long been resolved or timed out.

Try googling SPX Servicing Solutions. They list 204-111 as the equivalent of the Jaguar JD115. Could save you a lot of time and $$.

I've borrowed a JD115 several times and the SFX illustration looks identical.

As GGG said probably moot now but I have to say I think it is elusive because you don't need it.:icon_deadhorse:

I have used the regular style two piece compressors just fine and when I was stupid enough to let PepBoys work on my car and replace the front shocks I am fairly sure they did not have Jaguar part JD115 :P

Found this...
 

Some more :icon_deadhorse:.....

These are pics of the tool and a pic of a home made tool. The rod is about 18" long and fine threaded. A 1/4" hole is drilled about 3/4" from the top end of the rod to allow a 1/4" pin to pass thru for the anchor point. The other dowels are guide pins to help locate the lower spring pan during reassembly.They are the same thread as the bolts that hold the pan in place. Don't let the rod spin while tightening or loosening and check the condition of the upper key way to be sure it is not too rusted out to hold the upper end of the rod.

Doesn't seem too hard to duplicate, and the jag style tool seems safer than using regular spring compressors due to the curve in the spring.
Anyway, hope this helps somebody, just be careful!

The SPX tool 204-111 is the JD115 it's just their stock # it is $513.00

JD115 Same as Old JD 6F??
 

Is the JD115 Spring Compressor the same as the JD 6F Spring Compressor the repair manual says is needed for pre 1987 Jags? Looks similar in the pictures.

The soft metal 3/4" all-thread available in hardware stores throughout North America will work fine for the few times you will need it. If you are going to use it daily in a repair shop, you might want better quality rod but you can also make 3 or 4 and use them a few times and discard for the cost of the rod. (maybe $10 for a 2 or 3 foot section??)

Drill a 5/16" hole through an end of the rod and use a heavy roll pin like the Jaguar tool. Or you can press fit a 5/16" section of round stock short enough the fit the oblong hole in the top of the spring seat. Rotate the rod 90 degrees, drop it into the slots and use the all-thread to compress the lower plate to the lower arms.

The Jaguar tool is 20mm threaded rod but 3/4" (19mm) is 'close enough'.

I fabricated my own compressor based on one created by Win at the Jag-Lovers forum, with a few of my own tweaks (e.g. the self-aligning washers). The parts were all purchased from McMaster-Carr (mcmaster.com). I used 20mm threaded rod because I wanted to purchase a ratcheting wrench to speed up the process of compressing and decompressing the springs. A 30mm wrench seemed like a better long-term choice for working on our metric cars than the Imperial equivalent (1-3/16 in.?), which would probably never have been used again. As it turned out, the 30mm wrench was exactly what I needed to remove the mounting studs when I rebuilt the differential.

Here's the compressor, 30mm ratcheting wrench, and the 8mm rods used to guide the spring pan:

Here's a phototutorial showing how I made the compressor and how it is used:

Several guys have made similar compressors but simply used a stack of heavy washers as the "thrust device" instead of the drilled steel ball.

Cheers,

Don

Steel balls are always good to have :D

I built my own following Don B's pics.- thanks again Don- I used standard threaded stock and hardened nuts with a simple stack of flat washers. Yes I was careful, Yes I wore one out and made a second. Yes the cost was under $30.
