Jcovenden Posted August 21, 2020 Share Posted August 21, 2020 As a first post I would be very grateful for some information on a LIMA O Gauge 4F gear train. As a lockdown project I have been trying to restore this loco to run on a newly created garden railway. The motor is overhauled and picks up power from the rails but I am missing a gear to connect power to the rear wheel. The pinion on the motor shaft is present, as is the next gear wheel that engages with it (this has a small cog to the rear) . But the next gear wheel that connects this small cog to the large gear wheel attached to the rear wheel is missing. Is this gear wheel unique to the 4F or is it shared with other LIMA models - even other gauges. Can anyone please suggest a source for this rather crucial part! With thanks.

PatB Posted August 22, 2020 Share Posted August 22, 2020 It's 35 years since I looked inside a Lima 4F, but memory tells me that the motor and gear train were rather small. Quite possibly comparable to the pancakes in their 00 diesels. Hopefully someone on here might have a stash of Lima gears that could be measured up for a possible fit. 1 Link to post Share on other sites More sharing options...
Il Grifone Posted August 22, 2020 Share Posted August 22, 2020 If they are the same pitch as the 00 gears something might be available from China as they are a standard size. Link to post Share on other sites More sharing options...
Jcovenden Posted August 23, 2020 Author Share Posted August 23, 2020 Thanks for all the replies to date and suggestions. The gear train on the O gauge 4F does look very small and the earlier observation prompted me to look this morning at those in a pancake motor-driven LIMA HO/00 GWR 94xx. The first gear on the 94xx (that feeds off the pinion on the motor shaft) is identical with the first gear on the O gauge 4F! (assuming that the 4F gear is the correct part). Unfortunately the next gear ( the one I am missing) on the 94xx is very small and is not common to the 4F. This at least suggests that gear parts could well be common between LIMA's O and 00 gauges.

alastairq Posted August 23, 2020 Share Posted August 23, 2020 https://www.ebay.co.uk/itm/363048068639 Has a useful photo of he gear train too. Maybe an email to the vendor might elicit some assistance? 1 Link to post Share on other sites More sharing options...
