Stuart Wilson Posted April 2, 2016 Share Posted April 2, 2016 How much end float is there normally on the 1500 crankshaft? Quote Link to comment Share on other sites More sharing options...
thescrapman Posted April 2, 2016 Share Posted April 2, 2016 should only be a few thou. 5 max or similar.If you can see the crank move, it is way too much, if you can feel it, probably too much, and hear it, about right. Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted April 2, 2016 Author Share Posted April 2, 2016 Bugger, can see it move.Looks like some internal investigation needed, hopefully new thrust washers will sort it Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted April 2, 2016 Share Posted April 2, 2016 8 - 12 thou not unusual. So long as it's not measured in mm!Thrusts can be changed with the engine in situ by dropping the sump and rear main cap.Nick Quote Link to comment Share on other sites More sharing options...
WIMPUS Posted April 3, 2016 Share Posted April 3, 2016 I've done the thrust washers (and shells) on my 1500 a year ago.Done it with the engine in the car and one thrust washer (clutch side) looked pretty bad ! ...Rear main bearing cap off, then get a zip tie or something to push the old thrust washer out or rotate the engine a bit 🙂 Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted April 3, 2016 Author Share Posted April 3, 2016 Cheers chaps. I've not got the engine fitted yet so I'll get it on the engine stand and take the sump off and have a look.It's got about 1mm which is why I noticed it, hopefully new thrusts will sort it.

glang Posted April 5, 2016 Share Posted April 5, 2016 Thats a lot of play! Hopefully you wont find damage to the crank because either a thrust has fallen out or they have worn down to the base metal..... Looks like the biggest oversize thrust available is only 15thou (0.381mm) Quote Link to comment Share on other sites More sharing options...

Stuart Wilson Posted April 6, 2016 Author Share Posted April 6, 2016 I'll look at it once I've got chassis sorted Quote Link to comment Share on other sites More sharing options...
Deleted User Posted April 9, 2016 Share Posted April 9, 2016 Quoted from Nick Jones http://www.customthrustwashers.com/NFI - satisfied customer.Nick Brings back memories - after some Glacier thrust washers fell out of a recon engine in a customers car in Luxembourg, I ensured that all future engines had Vandervall or equivalent for the rear one - glad to see someone has fully sorted the issue.

don cook1 Posted April 18, 2016 Share Posted April 18, 2016 How have you got on Stuart? You say 1mm (39.3 thou) gap but you have to measure the end float from a known datum point and that is with standard size thrust washers fitted. Order standard size and fit them, then measure the gap with a dial gauge or feelers. Once you have the 'new' total gap size, in thou, deduct the required clearance (is it between 4-8 thou and what is left is what you have to make up with oversize.I'd order a set of standard size for the datum and at the same time take a punt and get another oversize set at whatever you think you'll need. You can then mix or match. I'd also have a good read up of how to measure the end float as I believe there is some inertia by the con-rods that may give a false reading, my engine builder used a large lever rather than just pushing/pulling by hand. Make sure the slotted (oil way) side of the washers are against the moving part i.e. the crank. Quote Link to comment Share on other sites More sharing options...
Stuart Wilson Posted April 20, 2016 Author Share Posted April 20, 2016 I've not had a chance to look at it yet as been busy with working at weekends. I'm getting busy over the next few weeks but will have to get cracking with it soon.My plan was to order up a selection of various sizes and see what I come up with, I say about 1mm that is just looking at the front pulley when its pushed/pulled, not with a DTI or feeler blades Quote Link to comment Share on other sites More sharing options...
