Fitting Tillett seats

[Squadron Leader]

What's the secret to fitting these to you Caterham?

 

I have just spent the best part of today trying to fit the drivers side one in my car. I have managed to get the two rear bolts in but there doesn't seem any way of getting your fingers onto the front two. Also I now have a floor that looks a bit like a Swiss cheese - lots of holes in it.

 

There must be a knack. Can the power of BC help?

 

Many thanks,

 

Phil

The runners are a pig. Some weld the screws into the runners, I persevered, there's no real knack other than to put the screws in, position the seat over so that the screws go in the holes (some persuasion may be required) then get the nuts on a few threads. Then you have to squish your arm down the back of the seat to get a screwdriver on the side of the head, and use your extremely useful friend to tighten the nuts underneath. For the front ones, slide the seat all the way back and repeat.

 

Once the floor starts sagging, and you get some grit in the runners, they'll become awkward anyway so I got some more fixed runners, put the seat where I wanted it, marked the fronts and sides of the runners, jumped out, removed the runners, marked where to drill the holes through the floor, drilled, and refitted using screws from underneath.

Use cap head allen bolts put in from the top a long extension and a suitable allen bit, then nylocs and washers from the bottom.

 

If you use normal bolts they are meant to be held captive in the ally chanel however they have a habit of 'escaping' and then it's a right faff trying to secure them to undo the nuts.

Thanks for the replies chaps. Problem is, I can get the back bolts in by sliding the seat forward, but when I slide it back to the rear bulkhead it still won't go far enough back for me to even see the front two bolts

I think I used a screwdriver to wedge the bolt above at the front of the runners whilst I got the wife underneath tightening the nut on. Worked fine, although I think I had to put a bit more of my fair share in to doing the washing for a day or two as a repayment

I did this on my own! Get the bolts in place - lower them (carefully) through the floor - get a nut on to the bottom and as you get purchase pull the bolt towards you with a spanner above the washer as you tighten the nut. When the nut is mostly on, you'll find that the bolt stays mostly in place as it's in a groove.

 

Alternatively, don't bother, as they're a pain, and use ally box runners on the drivers side too - much better, as long as you don't need to move the seat forwards. Mind you, the sliders will be full of grit within a couple of weeks anyway!

PS enlarging the original holes slightly may make it easier to fit the bolts.

Just covered this on my thread 27 june , next page ! Not suprised other folks have found it a bit tricky !

Put extra nuts on the bolts first and tighten them solid - 1/4" increase in seat height won't make any difference. It also helps the runners to work a little more freely

Sounds like a wizard wheeze! Similar fitting issues with my leather S-type seats and, even when finally in, the base of the seat scrapes along the floor in a horrible seat/grit/aluminium interface.

 

Will probably give it a go.

Welding the back bolts to the rail is an effective way of stopping them turning , makes it easier if you have to take seat out another time too .
