I have got the shocks put on the 109 at last but the standard ones are too short with the lift that the ex military chassis gives it.
Does anybody know the part numbers for the correct ones I need?
They need to be at least an inch longer than the standard ones
I did a search and somebody asked the same question a few years ago but never got an answer..
I found some 1 ton shocks listed at Paddocks are they longer than standard ones?
Thanks

Yes, the 1-ton shocks are longer than the standard ones as the 1-ton has the same extended shackles as the military 109.
The part numbers are RTC4231 front and RTC4233 rear.
There's info about the the shock dimensions on the Heystee Automotive website as part of their range of parabolic springs:

I have the standard Britpart 1-ton rear shocks on my 109 ex-military and they've been fine over the past 9 months. I did consider a parabolic upgrade but decided to stay with the standard springs.
 
Thats great info thanks. I have got a feeling that the ones on it at the moment are probably swb- it was like it when I got it so don't know whats gone on in the past.....
Those 2 part numbers you gave are the ones I was looking at on Paddocks website so I will go with them now I know somebody has got first hand experience of them.
Thanks
 
When I needed std shocks for my ex-mil LWB (mil chassis and 2" lift) the parts numbers were the 1 ton ones and they fitted fine, but watch out as the brake hoses are 2" longer too and I recall haveing a lot of trouble getting the right part numbers. I would be asusred the number was correct and the part was 2" over only to find it was std length when it turned up, took 4 attempts.
 
Yes I have got some +40mm braided hoses on order as well, I think there's a kit of 3 (DA242040S) for around £30 from Paddocks in a blue box.
 
As an addendum to this the shocks have arrived and are indeed longer, the braided hoses though have a short flat thread one end thats for screwing straight into the brake cylinder on the hub.
My lines have an intermediate short length of copper that links the flexy to the cylinder, would it matter if I got rid of that do you think and fit the flexy straight to the wheel cylinder-its a double type with a copper link between the two. The braided hoses are more than long enough to accomodate this.
Thanks

Is yours an S2 or S3? The brake pipe arrangments are different. Mine is an S2A and these fitted, you may have the S3 set up. Mine run from the union on a braket by the chassis direct to the top cylinder. I also bought a box of assorted copper washers, they come in very handy for jobs like this.
 
Its a series 2(1960) on a series 3 military chassis so I'm thinking as long as it fits and works it'll probably be OK.
don't want to do anything stupid though so put the question out there.
Its a bit of a mish mash but with so many arrangements to choose from the choice is a bit of a minefield.

A couple of before and after pics of the original flexy setup and the new braided ones.
They seem to fit perfectly without the copper link piece to the wheel cylinder.

On a related note I put on a new master cylinder as the old one was leaking but when I tightened up the nuts to hold it to the servo there was no fluid coming out of the rear port on the master cyl.
When I slackened it off a bit fluid poured out so had to put on an 'O' ring and make a rubber gasket out of a bit of old inner tube to act as a spacer. I'm guessing the plunger was too tight onto the master cyl and not letting it return fully to give a full stroke but never come across this before has anybody else?
And yes it was in a blue box.....
 
New braided hoses are looking good! Are those the new shocks or the originals?
It sounds like you need to adjust the pushrod on the master cylinder. I assume it's the same as the Series 3 i.e. you remove the plate on top of the brake pedal box and adjust to get around 1.5mm free play. You need a bit of free play on the pushrod otherwise the port at the end of the m/c stays closed and pressure can build up in the brake circuit.
 
Those are the original shocks, turned out when I put the new ones on they were the same so even though they are 1ton shocks they are still pretty much at the extent of their travel. The back ones were a couple of inches longer though.

I should have said its a series 3 servo pedal box to upgrade the system, there's no adjustment for the plunger (unless I'm missing something) so I made a rubber gasket and put a thick O ring on it . Seems to be fine now and got a good hard pedal.
