Hi Zak.
you might consider calling Richards Chassis or XD chassis. XD in particular build up their chassis using OEM rails and tailor them to suit - there are also other companies that take Puma-era chassis and convert them for use in earlier models. Instead of asking their advice (which might not be forthcoming), you could ask to buy a Puma-TD5 conversion kit complete with measurements. You might end up paying for brackets you already have, but at least they'd be engaged in supplying the correct measurements. Just a thought. |

Another way to help...
If you can get hold of a 300Tdi gearbox crossmember (bolt in, off a discovery), then mount that and bolt the gearbox to it along with the engine (suspended from a crane of course!) That way you'll have the right front-back location for the engine mounts. as far as I remember when I've built the last couple of Td5's, the engine chassis brackets are the same for both sides. |

Thank you guys, that's great advice and much more helpful than countless replies I had on french boards
Sounds good. I had the impression that only a handful of brands produce the Puma chassis. Do you think I would be able to find out the origin of it?

Just wanted to make sure that the fitting "template" is suitable for all chassis. |

If engine mounts were welded in the wrong place, would that not put the distance from engine mount to gearbox mount off, and you would not be either to fit either the gearbox mounts or the engine mounts depending which you engage last?
I am not too familiar with the Td5 engine mount brackets, but are left and right mount brackets the same? If not, possible that you welded left bracket on right side of the chassis? But I believe that the chassis brackets are identical left to right, only the engine brackets are of different lengths. Edit: dorsetsmith confirmed my thinking. Dimension B = 2A. So left and right mount brackets are equally spaced from centerline. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

I think I'm right in saying that the OEM manufacturer for the puma chassis was GKN Marsland (happy to be corrected). They also sell to the aftermarket. Some companies buy complete Puma Chassis (or even just the main rails) from Marsland and modify them to suit different models. Re: Dixon's not being willing to export, I'm sure there are plenty of people on the forum who would be willing to receive the delivery in the UK and forward it on to you. |

@dorsetsmith thank you very much for the measurements! would you have the second page in a better quality?
As of now, the engine is laterally centered. The fan fits perfectly in the cowl. The only thing that bugs me is a 10mm difference I found for this measure between the rails (63 vs 64cm). Is the Puma chassis supposed to be different? Click image to enlarge @Dinnu, brackets are the same yes @Gasket, Richards confirmed the chassis is not theirs. Will try with Marsland @excossack thanks for the offer, that's very kind. My company is based in Sheffield so I already have a UK shipping address 
I'll go ahead and order Dixon's kit (although he could not confirm that it would be 100% suitable for the TD4 chassis) |

I have a slightly different chassis dimensional drawings, and the inner dimensions between the chassis rails is stated at 636 - 634mm. So at worse your chassis is 4mm out of spec.
It is not clear in the drawing if this measurement is at the top edge of the chassis rail, or if it is between the 2 brackets that are welded below the rail for the front jacking point. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

its not show on 110 drawings but looked at 90 drawings and as ^ 636- 634mm just had look my 90 chassis leg in side dimension 635mm just behind bumper at the top have you check at several pinots along your chassis may be gav heat has distorted it as i had noted from gav chassis pic that LR tie down have been left in place and the post gav fettling is not been cared out by galvanizers Last edited by dorsetsmith on 3rd Sep 2021 10:43am.
