trendkill Posted February 12, 2012 Share Posted February 12, 2012 I've been asked by a friend to shorten a 110 chassis he has lying around to a 90" so he can build it up with 90 parts Whats the best way of going about this? Many thanks..... Quote Link to comment Share on other sites More sharing options...
Frax Posted February 12, 2012 Share Posted February 12, 2012 Sell the 110 and buy a 90. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted February 12, 2012 Share Posted February 12, 2012 A 110 is longer between the wheels (obviously) and behind the rear wheels. As Frax said sell it and buy a 90 chassis. Legally I think that would also be your only option unless you fancy an SVA/IVA (I always get them mixed up) test. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 12, 2012 Share Posted February 12, 2012 Does he know a 110 chassis is not just a 90 with an extra bit in the middle? They're deeper and have other changes like the fuel tank being in the back. Quote Link to comment Share on other sites More sharing options...
trendkill Posted February 12, 2012 Author Share Posted February 12, 2012 I'm guessing he knew none of the above It'll be for an off roader so SVA etc... isn't a problem. The fuel tank won't be a problem, just need to know where to cut out and re-weld Thanks again Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted February 12, 2012 Share Posted February 12, 2012 The dimensions of the 90 and 110 chassis are in section 76 of the workshop manual. Download Rave and you should have all your answers hopefully. Quote Link to comment Share on other sites More sharing options...

stuck Posted February 12, 2012 Share Posted February 12, 2012 Surely if you sell the 110 you would make more money than it would cost to buy an off road only truck? Plenty of off road only trucks on fleabay. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 13, 2012 Share Posted February 13, 2012 If he can't work out where to cut by looking at it then he probably shouldn't be going near it. Of course the rear prop will be wrong as the 110 will have a salisbury back axle, so you'll need to make it shorter than a std. 90 one.

need4speed Posted February 13, 2012 Share Posted February 13, 2012 ...Which will have a knock-on effect for trailing arm mounting points etc Quote Link to comment Share on other sites More sharing options...
sean f Posted February 13, 2012 Share Posted February 13, 2012 Got to say my first advice would be like others have said if you want a 90 sell the 110 and buy one. If it is offroad only and vehicle id is not a problem then buy a second hand 90 chassis and rebuilding all the parts onto it will be much easier. Even an old chassis once it is bare can be patched up easier than the work involved in shortening a 110 chassis. If you are determined to do it this way then cut inbetween the suspension mounts so you end up with two chassis sections with axles attached that way all the suspension mounts etc stay correct, measure very carefully before welding up to keep things square and after welding it plate over the welded area, if done well it should be stronger than origional. The back end of the chassis you will probable have to be fabricated to fit not sure if you could get away with buying a 90 crossmemeber and extentions or not. This was the way we used to cut range rover chassis down to fit under series motors for trials etc(pre SVA or IVA days then and 90's didn't exist!). If you don't get it right it won't drive well and will look like an abortion. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted February 13, 2012 Share Posted February 13, 2012 If you are going to shorten it, i'd do it the way my friend shortened his rangy chassis for his 88. He cut it between suspension mounts (radius and trailing arms), and then welded 3mm thick plates inside the chassis, using plug welding (through a hole in the original chassis rails) and welded the inside corners of the new box. He also ran the grinder down the old corners of the chassis rail, and welded through there onto the new box section and dressed the weld back so it look original. He then slotted the rear section over the new box, butt welded old and new together, making sure it fused to the new inside box too, and plug welded aswell. He then dressed the butt weld flush, and then over plated all 4 sides with more 3mm steel plate. The chassis is 8 or 9mm thick at that point, on all four sides, extremly strong! But my first advice would be to get a 90 chassis anyway. Quote Link to comment Share on other sites More sharing options...
