Too tight 29 November 2009

I changed the oil seal on the OD output yesterday. Not too bad a job. The nut holding the flange in place is a castle nut with a split pin holding it in place so it was not torqued up too tightly and the flange just came off in my hand. I tapped the new seal in place using a couple of socket extensions through the propshaft tunnel. Lining the castle nut up to the holes was the hardest part of the whole job, I initially torqued it up too tight and could not get to the next slot and then had to undo it. The impact wrench had a bit of trouble then due to the slop in the extensions absorbing the energy but reordering them sorted that. I also tightened up the flange on the replacement diff, I don’t think I got to 200 ftlbs but it is certainly on tight!

Zerk fitting 29 November 2009

The replacement axle feels better to me so I fitted the new pinion seal to it. Now I just have to do the swap! I have also done the universal joints in the prop shaft. These caused me quite a bit of concern as they seem very tight when put back together. However the two ones I did first have eased up nicely and I assume the last one will as well. The first time I put the first UJ together it was tight and I undid it to check it which meant cleaning it all out and regreasing it. It went back together just the same but eased while I did the second. I ended up doing the third one twice as well due to getting it 90 degrees wrong which meant that the zerk fitting was fouling the arm on the prop shaft. The new centre support bearing and carrier is in place, that all went easily having undone the big nut while the prop shaft was in the car. I just need to put some fresh molybdenum sulphide grease on the sliding joint and fit the new protective bellows and the prop shaft will be all set to refit. However before that goes back in I’ll need to do the axle swap and also change the oil seal on the output of the overdrive as that is also leaking. The OD flange should not be as hard as the differential except for the fact that you can’t get tools on it directly as there is not enough room before the prop shaft tunnel starts.

I drove the car a bit more over the summer which was good although it still sounds a bit rough and I noticed noise coming from the drivetrain as well. I now have the car up on jack stands. The new impact wrench undid the pinion flange with no bother at all. When I removed the old oil seal I felt that the pinion had a bit too much movement in it which I thought might be the cause of the drivetrain noise. So I now have a spare rear axle on hand and I will see what the movement of the pinion is like on that one. I also intend to replace all the universal joints and centre bearing and carrier on the propshaft so that came out as well. I undid the big nut on the propshaft before removing it but I had to remove the starter and jam a screwdriver into the ring gear to do it. The centre bearing carrier was rotten and had torn through almost half way round. The rubbber gaiter protecting the sliding joint was missing and to cap it all the sliding joint had been put back together 90 degrees out of line which may have been the cause of the drivetrain noise. Some serious rust found in the front chassis members which may well need sorting before the next MOT. Maybe I’ll save up for a MIG welder.

The saga of the pinion oil seal continues. I ordered the new seal and was then a bit concerned as it did not look like the one that is currently installed but it turns out the design was updated so that is OK. A couple of weeks ago I made the counter hold lever from some angle iron and had a go at undoing the nut. I couldn’t shift it so I put a jack under the breaker bar. This then bent the angle iron and one of the bolts tore out of its hole. I tried again the next day with a bit more metal separating the bolt holes on the angle iron from the edge but it had the same result. I am now the owner of a new DeWalt cordless impact wrench and will try again at some point. Last weekend was a meeting in Basingstoke, primarily for Amazons but all Volvos were welcome and so we took the 1800 along. It was the only 1800 there which quite surprised me. Unfortunately the engine started to sound a bit rough during the trip there. It did however get us there and back OK. Oh well, something else to fix I guess. There was a missing clip on the passenger side headlight bowl which meant that there was no way to secure the chrome trim ring in place although it was reasonably firm fit. I did however decide it was time to fix it so I ordered a replacement plastic bowl from Amazon Cars and have just fitted it.

I had booked an MOT for 12:10pm today so at about 11:00am I headed out to the garage to start it up and get the battery charged. I used booster cables to hook up to my 240 to charge the battery for a while before I attempted to start it. I got the engine started on about the third attempt which was when I found that the clutch had seized again. I got the car out of the garage on the starter and let it warm up the engine while I had occasional attempts to unseize the clutch. It took quite a few tries before I finally broke it free and I did not have much time left before the MOT appointment. The MOT went fairly smoothly with just a headlight needing adjusting and an advisory for a seatblet beginning to fray. I did have a bit of a worry when I saw a liquid dripping from the car when it was up on the ramp but I eventually realised it was just the screen wash from the wipers test. So I now have a shiny new MOT certificate, the insurance and tax disc were also renewed last month so it is all road legal again. The pinion seal definitely needs replacing and sooner rather than later as there was quite a pool of oil from where it sat and dripped all winter. This is not an easy job as the torque required to undo the nut on the flange is quite high indeed, so you need a robust way to stop the flange rotating.
