Tom Posted June 29, 2022 Report Share Posted June 29, 2022 Hello, I’ve just fitted new timing sprockets and chain and then had a minor brain freeze when it came to the timing cover oil seal. I know 99% of the time the spring side faces in towards the oily side and the flat surface to the outside but I thought I’d double check!!!

Nigel Clark Posted June 29, 2022 Report Share Posted June 29, 2022 Yes, fit the oil seal with the spring to the inside of the cover and smooth side outwards. Nigel Link to comment Share on other sites More sharing options...
Tom Posted June 29, 2022 Author Report Share Posted June 29, 2022 Cheers Nigel, I was confident that was the case but thought I’d check👍🏼 Link to comment Share on other sites More sharing options...
Pete Lewis Posted June 30, 2022 Report Share Posted June 30, 2022 some of the seals with a plastic body dont seat well ( too thick) and can pop out the cover seals with a steel body seem to be much better when fitted just test push its firmly going to stay put Pete Link to comment Share on other sites More sharing options...
Tom Posted June 30, 2022 Author Report Share Posted June 30, 2022 Well the timing cover is back on, Seal tapped in nice and firmly👍🏼 I’ve nipped up the pulley nut but thought I’d check the best way torque it up? I’m thinking 4th gear, handbrake on and wheels chocked? I don’t have a socket big enough for my torque wrench but do have a big old spanner about 14inches my grandad left me. I’m thinking tighten it as much with the said spanner and then tap it a few more degrees with a hammer? I don’t want to risk damaging anything so thought I’d check my methodology here first!!

Wagger Posted June 30, 2022 Report Share Posted June 30, 2022 No need to use a hammer with a spanner that long. Your method is ok, but no need to go mad as there is a risk of twisting the crankshaft. Presumably you used this method to remove it? Some use Locktite for threads, but that can be a beggar to undo next time. Link to comment Share on other sites More sharing options...
PeteH Posted July 1, 2022 Report Share Posted July 1, 2022 I don`t actually know what the torque figure for the 1200 is?, (and unbelievably, the 1200 handbook does not specify it!!) but the 6 cyl, according to Haynes, is 90/100ft-lb. In which case 90lb near the end of 14" is still a big bag of sugar!. "Flogging up". A time honoured method in heavy engineering circles, is at best inacurate, and more learned art than science.!! Calculation of the degree of turn to provide said torque involves many factors, including wether there is a washer between nut and face, 2 friction surfaces, the pitch of the thread, et:al, and is something I have long forgotton!!.

Wagger Posted July 1, 2022 Report Share Posted July 1, 2022 90lbs would be very approximately hanging onto the spanner with your upper body. If you have weights, hang 90lbs with the spanner horizontal, at the 12 inch point. That is 90lb ft. It may be possible to make a 'Tab Washer'. Alternatively, mark the nut with paint on it and the shaft after tightening. You can then take a look periodically to observe any movement.

johny Posted July 1, 2022 Report Share Posted July 1, 2022 Luckily the crank pulley bolt seems to self tighten in use or certainly mine has never loosened and I dont give it that much torque... Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 1, 2022 Report Share Posted July 1, 2022 many do not take into account that putting in gear and applying silly torqurs to the crank can overload the damper springs and clutch disc hub 1200 engine toque output is 61 - 75 lbft so applying 90 lbft is overloading the drive line this needs to be in mind when gorilla's at work the lack of tightening torque specs for 1200/1300 is poor in the 60s torqure control was in its infancy there is a 150lbft for the blasted nut on the 1500 but nowt showng for 1147/ 1294 engines ............... so its do it nice hand tight after all it doesnt do that much Pete Link to comment Share on other sites More sharing options...
johny Posted July 1, 2022 Report Share Posted July 1, 2022 Course if it did come undone while driving it wouldnt be very pretty😱 Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 1, 2022 Report Share Posted July 1, 2022 you mean the fan belt wont keep a loose one aligned then Ha ! the 150 on 1500 nut gives many a nightmare to undo Pete Link to comment Share on other sites More sharing options...
Tom Posted July 1, 2022 Author Report Share Posted July 1, 2022 Thanks guys, I’m going with what I’ve done and the paint dots observation method 👍🏼 yes Pete that’s exactly what. i was worried about overloading the transmission with too much torque, I was worried about snapping a tooth of a gear, I hadn’t really considered the clutch!! I’m happy with it’s tightness. Putting my newly obtained water pump housing with the threaded areas for temp sensors on tonight, some of you might recall me asking about coolant sensor positions and temp gauges in general a few weeks back?
