Sam Monoogian Posted October 16, 2002 Share Posted October 16, 2002 Having previously scan-read many of the threads regarding Type 9 boxes I had missed the vital statistic - the 8.1 inch length input shaft. I'd been under the impression the 5-speed box I had was a Type 9 but on measuring the shaft last week I found it isn't. Without the long-input shaft the sandwich plate will be unnecessary, but this also means the whole engine/bellhousing assembly will be shifted back 15mm - will this cause a problem (apart from the less suitable ratios). Am I going to have to source a Type 9 box instead? If so, I've got 2 regular Sierra 5-speed 'boxes and a 4-speed rocket box to part-exchange - and I'd need it by Friday as I'm travelling down to Worthing to (hopefully) install the engine.

ECR Posted October 16, 2002 Share Posted October 16, 2002 Not sure which box you have got but can the gearbox move forward rather than the engine move back... If you can still mount the rear of the gearbox on the cross member then the main question is whether the prop shaft is long enough (which I would suspect it is...) Your gear lever will be further under the dash also.. Link to comment Share on other sites More sharing options...
oilyhands Posted October 16, 2002 Share Posted October 16, 2002 The input shaft (1st motion shaft) can be swopped from one box to another if you can lay your hands on one. I'm sure RRT or BGH would do it for you for a small fondling of wonga. The difference is only 1.2 inches... Oily Link to comment Share on other sites More sharing options...
Sam Monoogian Posted October 16, 2002 Author Share Posted October 16, 2002 Thanks guys. I think I'll have an attempt at putting it in "as is" and if it doesn't work, I'll take the box to have the input shaft swapped. Link to comment Share on other sites More sharing options...
Sam Monoogian Posted October 22, 2002 Author Share Posted October 22, 2002 Ok, short-input plan abandoned ☹️ Does anyone know roughly how much I should expect to pay to swap my box for a Type 9, or to have the shaft swapped? I'd like to have the 1st gear ratio changed at the same time but reckon it may prove too expensive. Link to comment Share on other sites More sharing options...
Nigel Riches Posted October 25, 2002 Share Posted October 25, 2002 Mr B.G.H, in Kent, he's the man to talk to to sort your 'box problems, what he doesn't know about these Ford gearboxes, got one of his and wouldn't have any other now, sorry I don't have his phone/fax no, regards Nigel.

NickD Posted October 27, 2002 Share Posted October 27, 2002 You can't just swap a short input shaft for long as the XR4i long input type 9s have different ratios to the short input ordinary Sierra type 9s so the input shaft gears have different diameters and numbers of teeth. Brian Hill is a good bet if you want advice and/or closer ratios. Link to comment Share on other sites More sharing options...
