As I said when joining the forum, I got myself a non-running Lada. I started it in the meantime and it doesn't sound too bad. When selecting any gear, nothing happens. I took out the transfer case this morning, and found that the splines on the intermediate shaft between the gearbox and transfer was pulled out from the cv joint. The rubber boot is also torn. Could this only be due to poor fitment (the transfer was fitted way back on the 2 mountings), or should I look for another fault as well? The splines on the tip of the shaft are damaged a bit, but the rest looks fine. Could I just re-assemble it?

Hi Jaco
I believe you were told "Apparently, it only jumps out of gear" ;D
The intermediate shaft is a good place to start. First you would need to replace the rubber boot - should get it locally. Check the rubber doughnut as well - replace if there are any cracks.
When you get the boot fixed put some CV grease in (not too much). Also check if the yellow cap on the front is still ok. Mine was leaking grease and I sealed it on the outside with red devil.
The splines should be ok - so after that you can put it back together.
If you still don't have drive - check if the high/low is not in neutral. If still no drive you should be looking towards your front diff. Hopefully that would not be the case.
Bottom line - die vorige eienaar het die kar deur sy gat getrek - so jy kan maar nog issues verwag - veral as hy lank gestaan het. Be patient and you will be rewarded.

Marius, Thanks a lot! And yes, the guy told me that it only jumps out of gear! Will let you know what happens!

To save time you should actually take the gearbox down as well.
DO THIS FIRST THOUGH - If the nut at the end of the output shaft on the gearbox came undone it would be the fifth gear jumping out. You can re-tighten it and road test it but chances are very good that the damage is done already.
Read everything there is to know about "the gearbox" before you take it down and download the repair manual if you haven't done so yet.
Quite a mission to take it down - but the box itself is very easy to work on.
It would also be wise to check your clutch for wear and I would also give the car a complete service incl changing all the oils.
Best of luck and let us know of your progress.
Marius

Hi Jaco
I also believe you should rather take things step by step, and make sure all components are in good condition - otherwise you might never trust and enjoy the car properly.
Regards
Danie

Inspected everything as you guys advised, except I didn't take the gearbox out. I refitted the transfer this morning, everything seems fine, except for one problem: there's not enough (+- 2mm) clearance between the front propshaft and the gearbox crossmember. It is catching while driving. I can't see anything wrong on any mounting or crossmember, any idea why this would happen?

Think I found the problem! I checked in the online manual, and came upon a picture of the transfer with the 2 propshafts connected. The picture shows the front propshaft connected the other way around from what mine is connected. The sliding part, with a much smaller circumference, should be at the transfer side, not the diff! Previous owner really messed around on this car!

Hi Jaco I would think that your TC case is a bit low (perhaps in the front of the TC only?). Remove some spacers/washers - if any? Hope that might solve the problem. Standard issue is a backing plate (x2) between the body and the TC and 4 spacers/washer (one on each corner) Just make sure that your intermediate shaft runs straight and smoothly in the end. What was the nut like on the end of the shaft (could have been re-tightened by the PO) and did you manage to fix the shaft? Regards Marius EDIT>> Got your previous message too late - shite that guy really did his best to f the car

Hi Jaco
I think having the prop round the right way will make a BIG difference. It pays for all of us to just have a quick glance at the manual when doing things. It is easy to make stupid mistakes ;D

Hi Guys, I took the car for a testdrive eventually, just to find out that it is jumping out of third gear! I also noticed that there is a bearing whine from the gearbox as well. I took out the box last night, will strip it tonight. Will I be able to obtain the GB bearings locally? I also need a Reverse light switch.
Regards Jaco

Hi Jaco
First check your reverse light switch by pushing the ball in with your finger. My switch works when I push in with a finger but not when in place in the box.
Gbox bearings are available in SA , you just need the old ones and take them in to a bearing shop and they will measure them and give you NTN,NSK,FAG,SKF, or import them from russia, or contact chris swales, ventz lazarov, jan pretorious

Thanks Ari, My reverse lights stay on, unless I unplug the wiring from the switch on the gearbox. As for the bearings, could this also be the reason that it jumps out of third gear?

Hi Jaco You could compare the bearings on your Gearbox with the list of replacement bearings on Baxter's website: www.ladaniva.co.uk/baxter/resources/ReplacementBearings.htmThe part numbers on the original Russian bearings are stamped on the bearings - so it will be easy to compare the numbers with the SKF bearing numbers on the above mentioned list. You don't have to buy SKF bearings - just tell any local Bearing Supplier what SKF part number (bearing) you need, and they will immediately know whether they could supply any other brand (NSK / NTN, etc) or not. The part numbers are more or less the same on all different brands. Regards Danie

Hi Jaco
Very unlikely to be a bearing - but not impossible. My guess would be the selector fork or the syncro - in that order.

Hi Marius
I do agree - on the other hand one never knows whether the previous owner kept the oil level at the correct level, or whether the oils have been changed when needed.
Low oil levels will obviously cause (bearing) overheating /lubricating problems, and could cause premature bearing failure. Dirty oil could easily act like a grinding paste, and destroy everything - including bearings.
Believe me, we often see this at work - in other applications.
Regards
Danie

Yes Danie - and judging by the way the PO screwed up with the car - NOTHING would surprise me.
