C15A - WO16 - Chev Blitz - Looking for guidance

[S LATHERON (RIP)]

Hello Andrew
Well my guess that the angle of cut was 45 degrees was correct.
You have written proof from the manual that this is the best way to proceed if any one has a frame to " adjust ". I have worked in the heavy truck industry in the UK at dealer level for 40 years [makes me old I guess] and have seen many chassis altered to suit various needs, I have also seen the bad effects of poor modification and unsuitable body mounting ,Twisted frames, Frames cracked at stress points like UN WELDED UN USED bolt/ rivet holes.
I am sure the guys that stretched this original 101 w/ base never thought that it would still be in exsistence 40 plus years on, maybe a compliment to there welding ability.
Regards Stephen

It is a bit hard to tell from the photos but it looks like they used the ends off a different chassis and slid it over the original chassis and welded it on
Behind the flitch plate they have used has it got the original hitch holes at the end of the original chassis (where the draw bar bolts) ?

Another interesting thing i noticed about your chassis is that it has the 1/2 crossmember behind the winch crossmember .The 2 i have here do not have this crossmember .These are both Sydney manufacture .I wonder if this was a Sydney vs Melbourne difference ?

Andrew & Stephen, Thanks for the detailed comments on how to approach the Chassis for me. All the comments are very, very helpful indeed.

We think that the Upper Chassis and the part used to extend the 101“ wheel base to 129“ is off a C60. They did slip over the C15A Chassis as you thought Andrew and used the holes for the leaf springs and the actual double springs off that same C60 set up for the rear set up. The welding is good & has a 2 ft overlap. They did fill in Holes too as you suggested & they are solid. I have braced with a L shaped section that is 1.3 m long and bolted to side and lower parts of the rail to temporarily straighten it all up so we can get everything together. Someone else suggested I replace the chassis with a new C15A. Not sure if I will be able to either find or want to do that. Still considering. In the mean time, we braced everything and have replaced all bolts on the rear, including the spring mounts. The brace you referred to was off the upper Chassis but they had installed that upper chassis upside down do it was questionable if it was adding much strength. I shaved 3 mm off each side and installed into the smaller C15A Chassis (bolted up and down) and think this will give us more cross strength and it has helped to bring everything into alignment, all directions.

Now that it is all stabilized, we can keep on moving it about and get on with our planning for the project.

Very happy to get all that timber off but also the WINCH… ! It was Huge and so, so heavy. Just listed on OZ ebay now. It is a monster. See the pictures. I am going to search for the original Winch for a C15A and put as it would have been originally with the PTO set up that is all in 100% working condition.

I think you may want to take your winch off ebay then
It looks to me like a cmp winch with the housing slid to one side to allow for the bigger drum ,of which you will probably find is the original drum with an extension welded in the middle
the cmp winches are big as they are basically a ford differential cut and modified

Thanks Andrew. Will take another look.

That is a CMP winch as Andrew stated with a widened drum on it and it fitted All models of CMP and was the only type of original winch for CMP's. So if you want to add a winch to your truck I'd remove it from eBay and keep it.

Got a hold of a Winch I can get to and recover in the Summer if we chose to go that way - Looks like this one also have brackets that will be easier to fit to my chassis. In summary, proceeding to sell the extended winch so save my hassle with the mods on the widened spool and altered configuration or keep as a nice piece about the place if it doesn't sell & use for parts in the future. Thanks for the opinions on solving this one for me. Very helpful.

Can anyone give me some pointers on this? Can't find reference in the manual.

Hello Peter
Looking at the picture of the winch you can buy. Yes that looks a lot less work than re working the heavily modified one. However is the whole chassis that the [summer] winch is in for sale? maybe not to daft an idea to use that rolling frame as a Basis for the rebuild and use the best parts of the two chassis to give a straight forward project At the very least just use the frame and add your own Cab, Engine ,Transmission Springs and Axles.
In this scenario providing they are both Chev You can Overhaul A complete Axle and suspension off your original unit and after Sandblasting summer frame just re assemble the Reconditioned units.,straight onto it.
Once you have a fully rebuilt truck you will have a pile of Used items that someone else may wish to take on Without the hassle of removing them!
Whatever you decide to do all the best

Stephen
